Öğe Age-Related Patterns of Physical and Physiological Characteristics in Adolescent Wrestlers(Montenegrin Sports Acad, 2015) Demirkan, ErkanThe aim of the study was to examine the physical and physiological differences as dependent on age of young wrestlers. One hundred and twenty-six 15 - 17 year old wrestlers volunteered as subjects in the present study. The physical and physiological profiles included body weight, height, body mass index, flexibility, anaerobic power, aerobic endurance, strength, speed, and body composition. The statistically significant (p<0.05) results are as follows: Age group 17 (AG 17) had significantly higher leg and arm anaerobic power and capacity (leg power: 952 +/- 216 Watt (W); arm power: 684 +/- 194 W and leg capacity: 489 +/- 101 W; arm capacity: 354 +/- 88 respectively) as compared to the AG15 with (leg power: 718 +/- 279 Watt (W); arm power: 458 +/- 149 W and leg capacity: 376 +/- 132 W; arm capacity: 247 +/- 86 W respectively). AG17 wrestlers were significantly faster than AG 15 (4.29 +/-.25 second -4.53 +/-.30 second respectively). AG 15 wrestlers had significantly lower right and left hand grip strength (right: 36.4 +/- 10.7 kg, left: 34.9 +/- 10 kg) than AG 16 (right: 43.9 +/- 8.4kg, left: 42.5 +/- 7.8 kg) and AG17 wrestlers (right: 46.6 +/- 8.7kg, left: 46.4 +/- 8.3 kg). In conclusion The results of this study suggest that height, body weight, fat free mass, arms - legs anaerobic power and capacity, speeds and hand grip strengths were increased both in one age range and in two ages range together with age progression, but it was clearly seen statistical differences in two ages range.Öğe Age-related physical and performance changes in young swimmers: The comparison of predictive models in 50-meter swimming performance(GDANSK UNIV PHYSICAL EDUCATION & SPORT, 2023) Demirkan, Erkan; Özkadı, Tuğrul; Alagöz, İsmet; Çağlar, Esin Çağla; Çamiçi, FurkanAbstract: Introduction: The purpose of the study was to investigate the age-related anthropometric and motor performance changes over time and their contributions to swimming style-specific performance in young different chronological age swimmers. Material and Methods: The study was conducted on a total of forty swimmers who were divided into 2 groups. The Anthropometric meas-urements were executed from 12 body parts, and body composition analysis was determined by using the skinfold method. The motor performance tests were performed for the assessment of standing horizontal jump, handgrip strength, flexed-arm hang strength, sit-up, flexibility, aerobic endurance, speed, agility, and balance. Simple Linear Regression analysis was performed to build the models for each of the swimming styles. Results: All the models indicated that aerobic endur-ance was a significantly predictive variable on all swimming styles (p < 0.001). The results indicated that the anthropometric and motor performance predictors changed depending upon the age pro-gression in each swimming style (p < 0.001). Conclusions: The effect of many variables on swimming performance is seen to be more evident in the following periods based on the increase of age. Aerobic endurance is a common variable that shows effectiveness on swimming performance for both all age groups and swimming styles.Öğe Assessments of world and national level wrestling teams at a pre world championship competition: Hydration, body composition and body mass alterations(Edizioni Minerva Medica, 2015) Kutlu, Mehmet; Demirkan, Erkan; Özbek, Mehmet EfeAim: This study examined the changes in hydration status, body composition and body mass alterations during the camping period a pre world championship, World (N.=14) and National (N.=38) senior wrestlers (N.=52) preparing for the World Championships. Methods: Urine specific gravity, conductivity and color measurements with, body composition analyses were conducted at the beginning of the camp and the end of the camp. Results: In general, no significant differences were obtained between the world and national wrestlers in body mass and fat percentage (83.3±20-84.9±18 kg; 12±6%-11.2±4%, respectively). However, a significant difference was detected in the changes of body mass between groups (world decreased [800±1 g] - national increased [600±1 g] [P<0.05]). Body fat percentage was also observed to have a similar bias with a decrease and increase, but the changes were not significantly different (P>0.05). No significant differences (P>0.05) were observed between pre- and post-test values of urine specific gravity, conductivity or color for both national team wrestlers. Conclusion: Wrestlers achieved to adjust to weight category in a close of period through competition weigh in. Dehydration training programs should be sustained during the whole camp seasons including the last days before the weighing process for matches.Öğe Comparison of physical and physiological profiles in elite and amateur young wrestlers(NSCA National Strength and Conditioning Association, 2015) Demirkan, Erkan; Koz, Mitat; Kutlu, Mehmet; Favre, MikeThe aim of this study is to examine the physical and physiological determinants of wrestling success between elite and amateur male wrestlers. The wrestlers (N = 126) were first assigned to 3 groups based on their competitive level (top elite, elite, and amateur) and then to 6 groups according to their body mass (light, middle, and heavy weight) and their competitive level (elite and amateur). Top elite and elite wrestlers had significantly (p <= 0.05) more training experiences and maximal oxygen uptake compared with the amateur group. In separating weight classes, light- and middle-weight elite (MWE) wrestlers had significantly (p <= 0.05) more training experience (7-20%) compared with the light- and middle-weight amateur (MWA) wrestlers. No significant differences were detected between elite and amateur groups (light-, middle-, and heavy-weight wrestlers) for age, body mass, height, body mass index, and body fat (p > 0.05), with the exception of height for heavy wrestlers. Leg average and peak power values (in watts and watts per kilogram) in MWE were higher than MWA (6.5 and 13%, p <= 0.05). Relative leg average power value in heavy-weight elite (HWE) (in watts per kilogram) was higher than heavy-weight amateur (HWA) (9.6%, p <= 0.05). It was seen that elite wrestlers in MWE and HWE statistically possessed a higher V[Combining Dot Above]O2max (12.5 and 11.4%, respectively) than amateur middle- and heavy-weight wrestlers (p <= 0.05). The results of this study suggest that training experience, aerobic endurance, and anaerobic power and capacity will give a clear advantage for the wrestlers to take part in the elite group.Öğe Declared and real physical activity in obese individuals as assessed by the questionnaire and accelerometer(Edizioni Minerva Medica, 2020) Gökçe, İsmail; Can, Sema; Demirkan, Erkan; Küçükler, Ferit Kerim; Turgal, EbruBACKGROUND: Due to the lack of precise research data related to the evaluation of the physical activity level (PAL) among obese individuals, the aims of the study were to evaluate declared and real volume of physical activity, and to assess the correlations between these methods. METHODS: The study consisted of 30 female (M-age =32.9 +/- 7.3 years) and 16 male (M-age=36.4 +/- 8.4 years) a total of 46 obese volunteer individuals were included (M-bmi:37.6 +/- 6.6 kg/m(2), M-bmi: 34.2 +/- 43 kg/m(2); body fat percentage: 42.1% and 35.2%, respectively). A cross-sectional study was conducted on the obese people. The inionnation form was prepared for obese individuals who applied the Health Institutions and body composition measurements were performed with Tanita BC-1000. PAL was assessed objectively by a Sense Wear Armband (SWA) for 7 consecutive days- and seven day later the participants fill out the International Physical Activity Questionnaire - Short Form (IPAQ-SF). For statistical analysis, the data were presented as mean values, Standard deviations (SD), frequency (f), and percentage (%). Spearman's Rho Correlation were used, and the significant level was P<0.05. RESULTS: According to IPAQ and SWA, 69.6% (10.9% plus 58.7%) of the participants (N.=32) estimated activity levels as correct. The PAL of 30.4% (N.=14) of the participants does not seem to be consistent. According to the IPAQ and SWA, the rates of moderate-vigorous physical activity (MVPA) were 80.4%, 67.4% respectively. Weak correlation was found-between IPAQ-MET and SWA-step/day and SWA-MET respectively (r((s))=0.381; 0.410 (P<0.01). CONCLUSIONS: Physical activity level being assessed by a subjective method was different from the objective method in obese individuals. In addition to this, sample groups and limitations should be taken into consideration when determining suitable methods.Öğe Determination the validity of the new developed Sport Experts® hand grip dynamometer, measuring continuity of force, and comparison with current Takei and Baseline® dynamometers(Edizioni Minerva Medica, 2015) Güçlüöver, Aziz; Kutlu, Mehmet; Ciğerci, Ali Erdem; Esen, Hüseyin Tolga; Demirkan, Erkan; Erdoğdu, M.Aim. In this study the Sport Experts ™ brand of hand grip dynamometer, measuring the continuity of force with the new developed load cell technology, was compared with Takei and Baseline® dynamometers, the current in use. It was tried to determine the correlation between them. In a study with provides use of clinical, orthopedic and rehabilitative purposes in the athletes and patient populations, this developed dynamometer can provide useful data by observing the continuity of force. Methods. The sample of the study included 60 badminton players in 2010-2011; consisting of Turkish Junior National male players (N.=16, age: 16.8±1.5), Junior National female players (N.=14, age: 16.9±1.6), amateur level male players (N.=15, age: 16.3±0.8) and amateur level female players (N.=15, age: 16.1±0.6). ANOVA was used in the statistical methods in order to compare the hand grip strength made by different brands; Pearson's correlation coeficient was used to determine the relationship level between dynamometers. Furthermore, test-retest reliability analysis was completed the new developed expert dynamometer. Results. There was no statistically signiicant difference in the comparison of the dynamometers (P>0.05). Besides, a highly signiicant relationship (r=0.95 to 0.96) was found among all three dynamometers. However, the reliability coeficient was found (Chronbachs ?: 0.989, ICC:0.97, r=0.97), (P<0.01) for the new developed expert dynamometer. Conclusion. Comparison between the dynamometers and the statistical results obtained from the correlation relationships shows interchangeability of dynamometers. As a result, our observation of force continuity (progression) of the athlete and patient populations is thought to be important.Öğe Do acute weight loss and gain affect hydration status in adolescent wrestlers?(Archives Budo Science Martial Arts & Extreme Sports, 2017) Demirkan, Erkan; Avcı, Emre; Gargi, RamazanBackground & Study Aim: The rapid weight loss and gain is a common practice in wrestlers within a week before the competition. The aim of this study was the effects of rapid weight loss and gain before official weigh-in, along with during the competition in adolescent wrestlers. Material & Methods: Twenty-four collegiate wrestlers (twelve of them as the competitors, other as non-competitor wrestlers) volunteered as subjects in the present study. Body composition was assessed by using a bioelectrical impedance device (bioelectrical impedance analysis; abbreviation BIA). Hydration status was determined via to urine specific gravity (USGV) that taken urine samples. The body mass and hydration status were evaluated: seven days before official weigh in (a); three days before the official weigh-in (b); morning of the official weigh-in (c); the official weigh-in time (d); before the beginning of the first bout (e); the following day morning (f). Results: There was a significant difference in body weight changes between the first weight assessment (a) and weigh in competition (d) in competitor wrestlers (p<0.05). In hydration status, there was a significant difference between the first USGV analysis (a) and other assessments (b, c, d, e, f) (p<0.05). However, there was no significant difference in hydration status between the weigh-in competition USGV (d) and others (e, f) (p>0.05). Conclusion: The duration of the official weigh-in and the competition is not enough for wrestlers to rehydrate. The process of weight loss and hydration status should be monitored by coaches, not before a week but in a long time. Individual fluid intake strategies should be developed for athletes to be minimising dehydration risk before and during the competition.Öğe Do the body weight perception and body mass index affect the participation of exercise?(SCIENDO, 2022) Can, Sema; Demirkan, Erkan; Çeviker, AbdulkerimStudy aim: In this study, it is aimed to find out the exercise preferences based on the Body Mass Index (BMI) and Body Weight Perception (BWP), and to determine the consistency between BMI and BWP calculated via the self-reporting method. Material and methods: The study was conducted total of 297 volunteers, included 174 females (Mage = 27.19 ± 9.94 years) and 123 males (Mage = 26.08 ± 10.15 years), who were members of the physical activity center. The height and body weight values were obtained based on the self-reports. BWP was assessed by asking “how do you describe your weight?” As a statistical analysis, the Pearson chi-square test and Kappa statistics were used. Results: It was determined that overweight/obese female prefered most the strength exercises, whereas, overweight/obese men, according to both methods, preferred the different kind of exercises (p < 0.05). When the mutual consistency of the BWP and BMI methods was compared, “average” level conformity was found in female, and “weak” level conformity was found in male (Female: ? = 0.48; p < 0.000; Male: ? = 0.21; p < 0.001). Conclusion: It could be said that the type and application protocol of the exercise has been related with the frequency and duration of the exercise for both of the methods. Besides, it could be said that there was a higher consistency among female participants at the level of participating to the exercise and they had similar exercise preference, frequency and durationÖğe Do the body weight perception and body mass index affect the participation of exercise?(Sciendo, 2021) Can, Sema; Demirkan, Erkan; Çeviker, AbdulkerimStudy aim: In this study, it is aimed to find out the exercise preferences based on the Body Mass Index (BMI) and Body Weight Perception (BWP), and to determine the consistency between BMI and BWP calculated via the self-reporting method.

Material and methods: 48 healthy women were included into this prospective cohort study and randomly categorized into control (n = 14) and experimental groups (n = 12). Spinning exercise sessions were conducted for 50 minutes three times a week for 8 weeks in the study group. The control group did not exercise. Immediately before and after the spinning program, each participant underwent the measurements of the body mass index, the waist circumference, the hip circumference as well as serum anti-mullerian hormone (AMH), estradiol (EM), follicle stimulating hormone (FSH) and luteinizing hormone (LH) levels. Results: There were significant differences in both of group in terms of antropemetric features (body weight, BMI, fat percent, waist circumference and hip circumference). There was only a significant difference of AMH in the experimental group. Conclusions: Spinning exercise would be an important cause of associated with a decreased serum AMH level in reproductive young women. Further research should expand the finding by questioning whether intensity or practicing is an important mechanism in reproductive young women.Öğe Effect of short-term aerobic and combined training program on body composition, lipids profile and psychological health in premenopausal women(Elsevier Masson SAS, 2017) Arslan, Erşan; Can, Sema; Demirkan, ErkanPurpose The purpose of this study was to investigate the effect of short-term (eight weeks) aerobic and combined training program on the body composition, lipids profile and psychological health (depression), and to compare which training method is more effective in middle-aged premenopausal sedentary women. Methods Sixty-four women aged 35–45 years (age = 38.8 ± 3.0 years) were divided into three groups: Aerobic training, Combined training and the control group and women exercised during eight weeks. The subjects’ body composition was measured with anthropometric tape and skinfold caliper and also body fat percentage, fat mass and lean body mass were estimated using BIA. Total cholesterol, triglyceride, high-density lipoprotein, low-density lipoprotein and also Beck Depression Inventory scores were registered at before and after eight weeks training. Results Aerobic training and combined training showed significant differences in fat percentage (?2.6%?, ?4.2%?, and 0.2%?, P = 0.044 respectively) and fat mass (?5.5%?, ?5.7%?, and 1.1%?, P = 0.034 respectively) compared to the control group. Considering the waist circumference, there was a significant difference only between the combined training and control group (?1.3%?, ?2.6%?, and 0.5%?, P = 0.048 respectively). Aerobic training and combined training groups showed significant differences in total cholesterol (?7.9%?, ?9.7%?, and 0.9%?, P = 0.022 respectively), triglyceride (?5.8%?, ?6.9%?, and 2.0%?, respectively, P = 0.012), atherogenic index (?13.5%?, ?16.0%?, and 2.3%?, P = 0.000 respectively) and Beck Depression Inventory score (?26.2%?, ?24.7%?, and 8.7%?, P = 0.047 respectively) compared to the control group. Conclusion The results of this study suggest that both training methods could be used for loosing body weight, fat mass and fat percentage for middle-aged women. Although the combined training seems a little more efficient, aerobic training is also practically easier in order to control and maintain in a large scale training groups.Öğe Fifty-meter swimming performance in young swimmers: the effect of anthropometric and motoric values on performance(Edizioni Minerva Medica, 2019) Demirkan, Erkan; Can, Sema; Özkadı, Tuğrul; Alagöz, İsmetBACKGROUND: Sports performance may be affected by many factors, such as physical abilities and physiological efficiency, technical skills, tactical strategy, and most importantly mental preparing. The main aim of this study presents that used a regression modeling approach to identify the affecting components, including anthropometric structure and some performance variables associated with 50-m swim performance in children. METHODS: In this study, a total of 22 voluntary athletes (male: N.=10; female: N.=12) participated that the age ranging from 11-13 years (female: 12.1±0.9 years; male: 11.9±0.7 years). RESULTS: There is no statistical differences in age, height, body mass and training experiences among groups that participated in this study (P>0.05). In breaststroke, the best time was correlated with aerobic endurance, height, arm length, flexibility, biceps circumference, hand length, upper body length; in butterfly style, it was correlated with aerobic endurance, standing horizontal jump (SHJ), height, and arm length; in freestyle, it was correlated with aerobic endurance and flexibility. In backstroke, it was correlated with aerobic endurance, SHJ. Multiple linear regressions showed that the effective variables on swimming scores are shown respectively; in butterfly style, aerobic endurance, arm length, and upper body length; in freestyle, SHJ, foot dorsiflexion, and aerobic endurance; in breaststroke, aerobic endurance, foot length. In backstroke, leg flexion. CONCLUSIONS: These results indicate that the importance of considering anthropometric characteristics and aerobic endurance in of young swimmers.Öğe How does artistic gymnastics and trampoline gymnastics training affect dynamic balance, abdominal strength, jump performance, and flexibility in adult females?(Palacky University Olomouc, 2023) Aydın, Erbil Murat; Gündoğan, Burak; Demirkan, ErkanBackground: Artistic gymnastics and trampoline gymnastics are an enormously popular group of sports that develops many biomotor skills, however, their effect on various aspects of fitness is not sufficiently observed. Objective: The study aimed to determine the effects of artistic gymnastics and trampoline gymnastics training on body composition, balance, jump performance, abdominal strength, and flexibility in adult females. Methods: Fifty-one adult female non-gymnasts (age 19.59?±?1.58 years, height 160.69?±?4.74 cm) were randomly assigned to three groups: the artistic gymnastics group (n?=?19), the mini-trampoline gymnastics group (n?=?16), and the control group (n?=?16). The training groups performed either artistic gymnastics or mini-trampoline training twice a week for 12 weeks. The control group only did warm-up exercises twice a week during the study. The measurements to determine the effects of different gymnastics training on body composition, dynamic balance, jump performance, abdominal strength, and flexibility were performed before and after the exercise programs. The pre-test and post-test of the variables of groups were compared using paired sample t-test. A one-way analysis of variance was used for between-group comparisons. Results: Both artistic gymnastics and trampoline gymnastics trainings significantly improved the dynamic balance, vertical and standing long jump, abdominal strength, and flexibility compared to the control group (p?Öğe Investigating the effects of wrestling gear in flatfoot deformity of wrestlers(Iermakov S S, 2020) Acak, Mahmut; Korkmaz, Mehmet F.; Taşkıran, Celal; Demirkan, ErkanPurpose: In this study, our aim was to determine the effects of wrestling shoes, wrestling mats and wrestling styles on postural deformation of the foot and to elaborate its possible causes. Material: Study group comprised of 158 athletes (109 males, 59 females) from 26 different countries who participated in the 12th World University Wrestling Championship. Of the athletes, 102 (59 females, 43 males) performed in freestyle and 56 performed in Greco-Roman style. The age range of the athletes was 19 to 31 years and they have done wrestling for 3 to 18 years. Were evaluated to determine the relationship between flatfoot deformity and gender, age, wrestling style and years in the sport. Footprint parameters were used to determine and evaluate the overall structure of the foot. The Staheli and the Chippaux-Smirak indexes were used in the study. Statistical analyses were performed using the SPSS v.21.0 software, with the significance level set at alpha=0.05. Results: No significant relationship was found either between the gender of the wrestlers or their age and their pes planus state. A significant relationship was detected between the wrestling style performed and the wrestlers' pes planus state, and between the years in the sport and their pes planus state. Conclusions: The fact that wrestlers wear the wrestling shoes for a long time can be a cause of pes planus. The center of mass of freestyle wrestlers shifts during continuous feet movement, and the surface of their soles extends the contact surface on the mat to maintain balance. This situation can also lead to a higher prevalence of pes planus in wrestlers. In addition, the wrestling shoes wrap around the Achilles tendon and thus the stretching of this tendon is restricted. Such restriction strengthens the opinion that freestyle wrestlers experience pes planus more.Öğe Physical fitness differences between freestyle and Greco-Roman junior wrestlers(Polish Academy of Science, Committee of Physical Culture, 2014) Demirkan, Erkan; Kutlu, Mehmet; Koz, Mitat; Özal, Mehmet; Favre, MikeThe aim of the present study was to examine physical fitness differences between Freestyle and Greco-Roman junior wrestlers. One hundred twenty-six junior wrestlers, comprising 70 Freestyle and 56 Greco-Roman wrestlers, participated in this study. The somatic and physical fitness profile included body mass, body height, body mass index, body composition, flexibility, maximal anaerobic power of the legs and arms, aerobic endurance, hand grip strength, leg and back strength, and speed. No significant differences were found in the anthropometric and physical features between Freestyle and Greco-Roman wrestlers. The Greco-Roman wrestlers had a significantly higher level of relative leg power, peak arm power, relative peak arm power, and relative average arm power than Freestyle wrestlers (p < 0.05). Greco-Roman wrestlers were significantly faster, had better agility, and had a greater level of leg strength than Freestyle wrestlers, but Freestyle wrestlers were more flexible than Greco-Roman wrestlers (p < 0.05). Discriminant function analysis indicated that peak arm power, agility, speed, and flexibility were selective factors for the differences between Freestyle and Greco-Roman wrestlers. In conclusion, the present study indicates that the differences between these wrestling styles promote physical fitness differences in elite wrestlers. The results reflect specific features of each wrestling style. © 2014 Editorial Committee of Journal of Human Kinetics.Öğe The comparison of some physical and physiological features of elite youth national and amateur badminton players(Niğde Üniversitesi, 2012) Güçlüöver, Aziz; Demirkan, Erkan; Kutlu, Mehmet; Ciğerci, Ali Erdem; Esen, Hüseyin TolgaThe aim of this study was to compare some physical and physiological features of elite and amateur badminton players. The sample of the study were totally 31 Turkish badminton players in 2010-2011 season; consisting of Youth National male players (n=16, age: 16.8±1.5) and amateur level male players (n=15, age: 16.3±0.8) from Sport High School. After the body composition of players were determined, agility test, sit and reach test, multiple reaction test, hand grip strength test and wingate anaerobic power test were applied to them. “Independent T-test” was applied for comparisons among independent groups. After statistical analyses, it was determined that elite players had higher values in height (cm), agility (second), right hand grip strength (kg) (p<0.01), body fat percentage and fat free mass (kg) (p<0.05) than amateur players. As a result, it was seen that the elite and amateur level badminton affected the height, agility, hand grip strength and body composition (lower body fat percentage and higher fat free mass) of players positively.Öğe The Effect of Exercise on Serum Homocysteine, Adma, Neopterin and Oxidative Stress Levels in Young Male Athletes(Int Journal Applied Exercise Physiology, 2018) Can, Sema; Demirkan, Erkan; Avcı, EmreElevated homocysteine (HCY), asymmetric dimethylarginine (ADMA), Neopterin (NP) and oxidative stress have been established as risk factors for vascular disease and coronary artery disease. The purpose of the study was (a) to assess the HCY, ADMA, NP, malondialdehyde (MDA) and glutathione (GSH) levels and (b) to determine the relationship between these parameters in wrestlers, track and field athletes, and non-athletes. 35 subjects in total, comprising of 15 wrestlers ((x) over bar = 17.6 +/- 2.3 years), 10 track and field athletes ((x) over bar = 16.6 +/- 2.2 years) and 10 non-athletes((x) over bar = 17.2 +/- 0.8 years) voluntarily participated in the study. The HCY, ADMA, NP, MDA, GSH levels as in subjects' blood was performed through the antecubital vein in the morning while in the pre-prandial state. There was a significant difference in ADMA, MDA, GSH concentrations between in track and field athletes and wrestlers. There was a significant difference in HCY, NP concentrations between wrestlers and non-athletes. There was a significant difference in HCY, MDA concentrations between track and field athletes and non-athletes (p< 0.05). The HCY and NP showed high level correlation in all groups (track and field athletes; r = .952; wrestlers; r = .886; non-athletes; r = .900; p< 0.01). The GSH and NP showed high level negative correlation in non-athletes (r = - .900; p< 0.01). According to the results of HCY, ADMA, NP, MDA, the lowest level was found in athletes and the highest appeared in the non-athletes. In conclusion, we think that regular training may have positive effects on cardiovascular and anti antioxidant level.Öğe The effects of detraining in young elite Wrestlers: Malondialdehyde, total oxidant status, total antioxidant status, glutathione(Kamla-Raj Enterprises, 2015) Demirkan, ErkanThe aim of the present study was to investigate the effects of a 12-week detraining period after a 9- month multicomponent wrestling training program on total antioxidant status (TAS), glutathione (GSH), malondialdehyde (MDA) and total oxidant status (TOS) and some markers of performance. Fourteen young wrestlers(age: 14.9±1.1 years)and twelve non-athletes (14.5±0.5 years), making a total of twenty-six, participated in the study. MDA and TOS were significantly higher during competition period in wrestlers compared to control (p<0.05). GSH was significantly higher in control group compared to wrestlers during competition period. There was no significant difference in TAS between controls and wrestlers during the competition period (p>0.05). The results of this study indicate that strenuous exercise leads to an increase in the production of MDA and TOS in wrestlers. Despite the detraining period, MDA and TOS concentrations were still higher in wrestlers compared to the control group. © Kamla-Raj 2015.Öğe The effects of different gymnastics trainings on body composition and some performance components in adult male non-gymnasts(Univ Ljubljana, Fac Sport, 2020) Gündoğan, Burak; Demirkan, Erkan; Aydın, Erbil Murat; Turgut, AbdusselamThe aim of this study was to compare the effects of artistic and trampoline gymnastics training on body composition and some of the physical fitness components in adult non-gymnasts. Forty-eight adult non-gymnasts were randomly assigned to three groups: a trampoline gymnastics group (TG) (n = 16), an artistic gymnastics group (AG) (n = 16), and a control group (CG) (n = 16). Two of the group except the CG performed different gymnastics training, including artistic and trampoline gymnastics twice a week during 12 weeks. The control group performed only a warm-up exercise twice a week along the study. To determine the effects of each gymnastics training on body composition, Y dynamic balance test that including six postural tasks, vertical jump, standing long jump and two different flexibility tests, were performed before and after the study for all groups. The AG and TG were significantly (p<0,05) improved when it comes to all bio-motor abilities in adult non-gymnasts after 12 weeks of training. But the trampoline gymnastics exercises may be seen to be more efficient compared to the artistic gymnastics exercises. The trampoline exercises may be recommended as an alternative mode of exercise for improving bio-motor abilities.Öğe The effects of exercise preferences on body fat and body mass index by self-report(Horizon Research Publishing, 2019) Can, Sema; Demirkan, Erkan; Ercan, SerkanBody fat (BF) and body mass index (BMI) that including physical fitness with health is important to protect and improve to the health.

A total of 442 volunteers, including 180 female and 262 male participated in the study. Body weight, height, BF and exercise preferences of participants who were members of the physical activity center were obtained according to their self-reports. Body fat analysis was determined by the BIA method (Tanita SC 330). In the analysis of the data, in addition to frequency and percentage values, independent t-test was used to compare between the genders and paired t-test was used for pre and post study in genders. Aerobic exercises affected in male body weight, BMI and BF (p<0.05), in strength exercises only BF affected (p<0.05), in combined exercises it was found that both genders significantly affected on all variables (p<0.05). As a conclusion, combine exercises in both of gender, compared with only aerobic and strength, was found that have a more positive effect on body mass index and body fat. © 2019 by authors, all rights reserved.
