Öğe ACUTE EFFECT OF STATIC WARM UP DURATION ON 50 METER FREESTYLE AND BREASTSTROKE PERFORMANCE(2016) KAFKAS, Armağan; EKEN, Özgür; ÇINARLI, Safa; KAFKAS, MuhammedThe purpose of this study was to determine the acute effect of different static warm up durations on sub-elite female swimmers on 50 m free and breaststroke swimming performance. Ten sub-elite women swimmers (age 22.46 ± 2.64 years, body height 163,4 ± 4.27 cm, body weight 56.39±9.72 kg, BMI 21.09±3.27 kg/m2 and BFP 21.77±8.06 %) were assigned randomly to 3 different warm-up protocols on non-consecutive days. The warm-up protocols consisted of only 5 minutes of jogging (WS), 5 minutes of jogging and 30 seconds static warm up (30-SS), 5 minutes of jogging and 60 seconds static warm up (60-SS). Following each morning (10.00) warm-up session, participants were tested on the 50 m freestyle and breaststroke swimming performance. Warm up protocols (WS, 30-SS and 60-SS) were compared by repeated measures analyses of variance (ANOVA). Based on the results of this study, it was found that there are significant differences between warm up I (no war up) and SS-30, SS-60 on freestyle and breaststroke swimming performance (freestyle p=.000, .014 and breaststroke p=.005, .000 respectively). When the 30-seconds and 60-second warm-up protocols were compared with eachother, a statistically significant difference was found in favor of the 30 seconds warm-up protocol in freestyle and breaststroke 50 m swimming performance (p = .001, .003). Therefore, swimmers shouldn’t prepare with static warm up protocols before 50 m freestyle and breaststroke swimming competition. However, there is still a need for studies investigating the effect of different types of warm up protocols on different distance swimming performance scores in the future.Öğe THE EFFECT OF SOMATOTYPE CHARACTER DIFFERENCES ON COGNITIVE AND BIOMOTOR ABILITIES(2016) ÇINARLI, Fahri Safa; KAFKAS, Armağan; EKEN, Özgür; KAFKAS, MuhammedThe aim of this study was to investigate the effect of somatotype differences on cognitive and biomotor abilities. This study was performed on 134 male (age average 21.85±2.34 years), 38 female (age average 21.28±2.22 years), and total 172 participants who do not have habit of regular exercise. The somatotype body types of participants were determined by Heath-Carter formula. As biomotor performance tests 30 m sprint, counter movement jump (CMJ), maximal anaerobic power (Ppeak), maximal anaerobic capacity (Pmean), Yo Yo Intermittent Recovery Test-1 (YIRT-1), hand-grip strength and flexibility (sit and reach) were measured. As measure of cognitive ability “The Transition to Higher Education Examination” (THEE) was used and evaluated the highest scores received by the participants. In this study participants with endomorph body type took the highest the THEE score (242.60±21.83), participants with mesomorph body type took lower scores than participants with endomorph (237.51±34.67) and finally participants who had ectomorphy body type showed lower scores than the ones with other two body types in terms of THEE scores (227.46±27.96). A statistically significant difference was found in jump test scores (p=0.04). According to these scores, participants with ectomorphic body type (p=0.34) and participants with mesomophic body type (p=0.14) the higher performance was seen in jump test scores. A statistically significant difference was found in YIRT1 test scores which is used to measure maximal oxygen consumption (p=0.00). According to results, participants with ectomorphic body type (p=0.01) and participants with mesomophic body type (p=0.00) the higher performance was seen in aerobic capacity scores. As result, participants with endomorphy body type who had the highest the THEE scores showed lower scores than the ones with other two body types in terms of hand-grip strength, flexibility, CMJ, 30 m sprint and YIRT-1 tests scores.Öğe The effects of different exercise programs on knee muscle strength and H:Q ratios of sedentary males and females(2014) KAFKAS, Muhammed; DURMUŞ, Bekir; KAFKAS, Armağan; AÇAK, Mahmut; AYDIN, AbdulkadirObjectives: Knee muscle strength is highly important for both sedentary and athletic people. For the reasons of both rehabilitation of injuries and performance development, strength is regarded as one of the most important elements of sports. The present study aims to determine the effect of different exercise protocols on knee muscle strength and H:Q ratios of young sedentary males and females. Methods: A total of 115 healthy and sedentary people 62 males (23.10±4.50 years, 71.90±8.90 kg and 177.80±10.30 cm) and 53 females (22.10±5.30 years, 54.40±6.90 kg and 166.60±6.00 cm) voluntarily consented to take part in the study. Participants were divided into randomly four separate groups according to exercise types (control, pilates, cardio, resistance exercises groups). Resistance exercise movements were made within 60% of 1-RM for each subject over 3 days during a week with 3 sets of 10-12 repetitions. CEG exercises were performed on a treadmill for 45 minutes over 3 days in a week with a 60% overloading rate. Pilates exercises were performed for 45 minutes over 3 days during a week under the supervision of a coach. Pilates exercises were divided into three different parts: (1) mat exercises (4 weeks), (2) Thera-band plastic resistance exercises (4 weeks) and, finally, pilates ball exercises at a beginner level (4 weeks). Results: There were significant differences between the pre- and post-exercises of knee muscle strength for REG, CEG and PEG after 12 weeks both gender and legs (p<0.05). Measures of muscle strength in both leg elicited substantial side differences in both flexor and extensor muscle strength. On average the female participants showed a 12.1% weaker flexor muscle strength (52.1±12.7 vs. 45.3±11.9 Nm, p<0.05) and a 6.7% stronger extensor muscle strength in the dominant leg (120.3±24.7 vs. 112.2±25.8 Nm, p=0.036). These data converted into H:Q ratios indicates that the knee H:Q ratio of dominant leg was 41.3±6.5% as compared with 38.6±6.9% (p>0.05) in the non-dominant leg.Öğe RELATIONSHIP BETWEEN SLEEP DURATION AND BODY COMPOSITION, BODY FAT RATIO AND WAIST CIRCUMFERENCE(2017) KAFKAS, Armağan; KAFKAS, Muhammed; EKEN, Özgür; YILMAZ, Nurkan; Kızılay, Fatma; KAYAPINAR, MuratIt remains unclear how many hours of sleep are associated with obesity in children and adolescent in Turkey. The main purpose of this study was to determine the association between sleep and body mass index (BMI), body fat ratio (BFR), waist circumference (WC) in children and adolescents. Data were from a nationally representative sample of 23633 people whose ages are 7-18 males and females from the Turkish Health and Fitness Survey. The relationship between sleep duration and body composition values were resolved by "Pearson Correlation" analysis. In the total sample, there was a significant main effect across sleep duration categories (5-6, 7-8, 9-10) for BMI, BFR and WC. Compared to those sleeping durations, 9-10 sleepers have got lower BMI, BFR and WC and 5-6 hours sleepers have got biggest BMI, BFR and WC. In conclusion In children and adolescent reduced sleep durations are strongly associated with greater adiposity.Öğe The Waist circumference in Turkish adults: 19 – 75 years age(2017) KAFKAS, Muhammed; ÇINARLI, Fahri Safa; YILMAZ, Nurkan; EKEN, Özgür; Kızılay, Fatma; KAYAPINAR, Murat; KAFKAS, ArmağanObjective: Waist circumference reference values can be vary among societies. Therefore, the purpose of this study was to determine the waist circumference values of Turkish adults people for 19-75 year. Material and Method: A total of 25.866 (11484 females and 14382 males) adult participants were recruited, grouped into categories of waist circumference in accordance with the World Health Organizasion cutoffs. Waist circumference was measured with a tape measure according to the recommendations of the World Health Organization. Results: It was found that waist circumference values varied at certain age ranges. Furthermore, there was a statistically significant relationship between the age variable and waist circumference values for male (r=.441) and female (r=.444) adults. It was determined that 87.91% of the male adults participating were to have normal values and 12.08% of them were to have higher risks of obesity related to the diseases, and 65.86% of female participants were to have normal values and 34.14% of them were to have had higher risk of obesity related diseases. Conclusions: The use waist circumference for the prediction of risk factor clustering among adults has significant clinical utility. These analyses should be continued in future studies in order to examine both health and reference values between societies
