Objective: This study aims at analysing the relationship between isokinetic leg strength and dynamic balance performances of MSK Urfa male volleyball players that play in Turkey Volleyball League of Swashbucklers.Materials and Methods: 13 voluntary volleyball players that played in MSK Urfa being a team in League of Swashbucklers in 2016-2017 season participated in the study. Bioelectric Impedance Measurement Device (Tanita MC 180) was used to measure body composition of volleyball players. Isokinetic dynamometer (IsoMed 2000 GmbH, Germany) was used to measure their isokinetic leg strength. Tecnobody Prokin device was used to measure their dynamic balance performance. The relationship between isokinetic leg strength and dynamic balance performance was determined by Spearman correlation analysis and the significance level was accepted as p <0.05.Findings: According to the data obtained from the study, there was no statistically significant relationship between the dynamic balance performance of volleyball players and the bilateral differences of quadriceps and hamstring muscles at the angular velocity of 60°/s (p>0,05); but there was statistically significant relationship between the bilateral differences of quadriceps and hamstring muscles at the angular velocity of 120°/s (p<0,05).There was no statistically significant relationship between dynamic balance performance and Hamstring/Quadriceps (H/Q) force ratio of dominant and non-dominant leg at angular velocity of 60°/s and 120°/s (p> 0.05).As a result; it was observed that the bilateral differences of hamstring and quadriceps muscles of volleyball players at 120°/s velocity affected their dynamic balance performance; but H/Q ratio at 60°/s and 120°/s velocity did not affect their dynamic balance performance.
ÖzetBu çalışmada, Karaköprü belediye spor ve Harran üniversitesi erkek futbol takımı oyuncularının bazı fiziksel (boy, vücut ağırlığı) ve fizyolojik (sistol, diastol, KAH) özellikleri ölçülerek kondisyonel (bacak kuvveti, sırt kuvveti, sürat 30 mt. esneklik) özelliklerinin arasındaki ilişkinin incelenmesi amaçlanmıştır. Ölçümlerden elde edilen verilere göre yaş ortalaması 23,46±3,50 /yıl), fiziksel özelliklerden boy ortalaması 176,20±5,10 (cm) ve vücut ağırlığı ortalaması 70,16±5,21 (kg), fizyolojik özelliklerden, SKB ortalaması 123,87±14,23 (mmhg), DKB ortalaması 73,60±16,42 (mmhg) ve İKAH ortalaması 64,50±10,48 (atım/dk), kondisyonel özelliklerden ise, bacak kuvveti ortalaması 101,83±40,48 (kg), sırt kuvveti 75,83±19,43 (kg), esneklik 34,16±6,65 (cm) ve 30 mt. sürat ortalaması 4,15±0,20 (sn) olarak tespit edildi. 30 mt. sürat ile bacak kuvveti parametreleri arasında ilişki olduğu gözlenmiştir (r=-,407). 30 mt. sürat ile sırt kuvveti (r=,429), ve 30 mt. sürat ile esneklik (r=,659) parametreleri arasında ilişki gözlemlenmemiştir.Sonuç olarak, Amatör futbolcuların sürat ile sırt kuvveti ve esneklik değerleri arasındaki ilişki anlamsızken (p>0.05), sürat ile bacak kuvveti değerleri arasındaki ilişki anlamlı bulunmuştur (p<0.05).Anahtar kelimeler: Amatör futbolcu, Bacak kuvveti, Sürat
Objective: This study aims at investigating the relationship between agility performance and perception and decision-making mechanisms of female basketball players.Materials and Methods: A total of seventeen elite female basketball player playing in Second League in Turkey Basketball Federation participated in this study voluntarily. The mean age of the participants was 21.53±2.47 (years), the mean height was 175.67±5.36 (cm) and the mean body weight was 66.80±7.76 (kg). Agility performance of the participants was measured by Newtest Powertimer 300, and perceptual and decision-making parameters were measured by Psychotechnic Vienna test system. Since the number of participants was less than thirty, Spearman Correlation test was applied.Findings: The average perception and decision making parameters of female basketball players were as follows: Visual Perception Test (VPT): 46.82±2.65, Reasoning Test (RT): 88.58±9.43, Response Quality and Speed Test (RQST) number of correct answers: 243.76±14.14, RQST time: 0.78±0.06, Speed and Distance Estimation Test (SDET): 45.00±2.76, Dual-Process Skill and Angle of View Test (DPS-AVT) viewing angle: 99.58±7.72, DPS-AVT collision number of cars: 3.76±2.13 and the number of collisions of DPS-AVT road sides: 3.23±2.01 (Table 1). When the correlation between agility performance (total time) and RQST time and SDET parameters was examined, a negative linear relationship was found (r = 0.842/r = 0.827, p < 0.01). However, agility performance (total time) and VPT, RT, RQST number of correct answers, DPS-AVT viewing angle, DPS-AVT car crash number, DPS-AVT roadsides collision parameters were not statistically significant (p > 0.05).As a result, in training contents, preference of visual stimuli, reaction and prediction studies will be important for improving agility. Furthermore, it is thought that cognitive parameters should be taken into consideration in the selection and orientation of athletes.
Objective: This study aims at examining the body composition of male football players who perform regular football training by Bioelectrical Impedance (BIA) method and comparing it with a healthy control group and investigating the effect of regular exercise on body composition.Materials and Methods: A total of 60 people participated in the study, including 30 volunteer male football players performing football trainings regularly from 11 Nisan Football Club playing in Turkey Football Federation Regional Amateur League (BAL) and 30 healthy volunteer control group consisting of male students from Harran University Medical Faculty. Both groups’ ages and body mass indexes are similar to each other. Bioelectrical Impedance (BIA) method was used for Osseosis, skeletal muscle weight (SMM), body mass index (BMI), body fat percentage (BFP), waist hip ratio (WHR), and basal metabolism parameters of the participants. The data obtained were evaluated with SPSS 23.0 statistical package program, and the significance level was evaluated as p < 0.01 and p < 0.05.Findings: There was no statistically significant difference between the values of age, height, weight, intracellular fluid, extracellular fluid, protein, mineral, skeletal muscle weight (SMM), body mass index (BMI) and muscle ratios of the experimental and control groups (p > 0.05). When the parameters of basal metabolism, Osseosis and skeletal muscle weight of the experimental group were discussed, no significant relationship was detected, although they were high numerically (p > 0.05). It was determined that the body fat percentage (BFP) of the experimental and control groups was correlated at p < 0.01 level and waist-hip ratio was correlated (WHR) at p < 0.05 level, which was statistically significant. As a result, although there was no significant difference between BMI values between the football players and the control group, the fact that the players' lower BMI values and lower waist-hip ratios showed that regular training reduces the risk of developing chronic diseases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
