The Relationship Between Body Composition, Anaerobic Performance and Sprint Ability of Amputee Soccer Players

The purpose of the present study was to investigate the relationship between body composition, anaerobic performance and sprint performance of amputee soccer players. Fifteen amputee soccer players participated in this study voluntarily. Subjects’ height, body weight, body mass index, body fat percentage (Jackson and Pollock formula) and somatotype characteristics (Heath-Carter system) were determined. The sprint performance at 10m, 20m and 30m was evaluated, whereas the counter movement jump (CMJ), relative CMJ (RCMJ), squat jump (SJ) and relative SJ (RSJ) tests were used for the determination of anaerobic performance. The results of the Pearson Product Moment correlation analysis indicated that body composition was significantly correlated with CMJ and SJ (p < 0.01), on the other hand, no measure of body composition was significantly related to the other component (p > 0.05). A significant correlation was found between CMJ, RCMJ, SJ, 10 m, 20 m and 30 m sprint performance (p < 0.05); whereas, in contrast, no measure of body composition was significantly related to the 10 m, 20 m and 30 m sprint performance (p > 0.05). In conclusion, the findings of the present study indicated that sprint performance was described as an essential factor in anaerobic performance whereas body composition and somatotype play a determinant role in anaerobic and sprint performance in amputee soccer players.

Relationship between efficiency of pistol shooting and selected physical-physiological parameters of police

Purpose – The purpose of this study is to investigate the relationship between selected physical-physiological parameters and efficiency of pistol shooting. Design/methodology/approach – In all, 237 male volunteers, studying at a Turkish Police Academy within the age range of 19-20 years old were investigated. The physical fitness levels were evaluated by valid and reliable test batteries. The efficiency of pistol shooting was evaluated by the total points of the bullets which hit the target from 10 m. Findings – Significant differences were found between the sets of students according to shot accuracy groups for wrist circumference, biceps circumference, femur diameter, hand grip strength, flexibility, aerobic capacity, reaction time, balance, coordination, state anxiety level, anxiety variability, average heart rate, maximal heart rate and heart rate changes. The correlation coefficient between the pistol shooting result and change in heart rate, anxiety variability, mean heart rate during shooting, coo...

Investigation of the Relationship between Physical Activity Level and Healthy Life-Style Behaviors of Academic Staff.

The purpose of the study was to determine the relationship of physical activity (PA) level and healthy life-style behaviors in academic staff in Bartin University, Turkey. The short form of International Physical Activity Questionnaire was administered for the determination of physical activity level of academic staff. Their PA levels were categorised as inactive, minimally active, and physically active by using MET method. For the determination of healthy life-style behaviors, Health-promoting Life-style Profile Questionnaire was used with self-actualization (SA), health responsibility (HR), exercise (E), nutrition (N), interpersonal support (IS), and stress management (SM) subscales. Results of Pearsons Product Moment Correlation analyses indicated significant positive correlations between total physical activity level and exercise (r=0.52; p 0.05). The findings of the study indicated that healthy life- style behaviors were not indicators of physical activity level of academic staff.

FARKLI SPOR BRANŞLARI İLE UĞRAŞAN BEDEN EĞİTİMİ ÖĞRENCİLERİNİN KUVVET VE ESNEKLİKLERİNİN BELİRLENMESİNDE MORFOLOJİK DEĞİŞKENLERİN ROLÜ

Bu calismanin amaci, Beden Egitimi ve Spor Yuksekokulunda yer alan farkli spor branslariyla ugrasan sporcularin kuvvet ve esnekligin degerlerinin belirlenmesinde morfolojik degiskenlerin etkisinin belirlenmesidir. Calismaya farkli branslarla ugrasan toplam 71(Xyas: 21.16±3.65 yil) sporcu gonullu olarak katilmistir. Calismaya katilan deneklerin morfolojik (boy uzunlugu, vucut agirligi, vucut yag yuzdesi vucut kitle indeksi, 7 bolge deri kivrim kalinligi toplami) ozelliklerinin belirlenmesi icin olcum yapilmistir. Vucut yag yuzdesi Yuhasz formulu ile hesaplanmistir. Esnekligin belirlenmesinde otur-uzan testi kullanilirken toplam pence (PK), bacak (BK), sirt (SK) ve toplam kuvvet (TK) belirlemesinde ise izometrik bacak-sirt kuvveti dinamometresi kullanilmistir. Sirt, bacak, pence ve genel kuvvet degerleri arasindaki iliskilerin degerlendirilmesi amaciyla Pearson Product Moment Korelasyon Katsayisi yontemi kullanilmistir. Elde edilen boy olcumu ile sag el pence kuvveti (r=.267, p<.01) ve toplam kuvvet degeri (r= .354, p<.05) arasinda pozitif iliski bulunurken kilo olcumu ile sag el pence kuvveti (r=.250, p<.01) ve toplam kuvvet degeri (r=.542, p<.05) arasinda pozitif iliski bulunmustur. Elde edilen 7 bolge deri kivrim kalinligi toplam degeri ile (r=.286, p<.01) sol pence kuvveti arasinda pozitif iliski bulunmustur. Sonuc olarak, calismada ki bulgular Beden Egitimi ve Spor Yuksekokulunda yer alan sporcularin morfolojik degiskenlerin kuvvet performanslarinda belirleyici rol aldigini gostermistir

Comparative analysis of the 1-mile run test evaluation formulae: Assessment of aerobic capacity in male law enforcement officers aged 20–23 years

ObjectivesThe purpose of this study was to compare values of aerobic performance in the 1-mile run test (1-MRT) using different formulae.Material and MethodsAerobic capacities of 351 male volunteers working for the Turkish National Police within the age range of 20–23 years were evaluated by the 1-MRT and the 20-metre shuttle run (20-MST). VO2maxvalues were estimated by the prediction equations developed by George et al. (1993), Cureton et al. (1995) and Kline et al. (1987) for the 1-MRT and by Leger and Lambert (1982) for the 20-MST.ResultsThe difference between the results of the different formulae was significant (p = 0.000). The correlation coefficient between the estimated VO2max using Cureton’s equation, George’s equation, Kline’s equation and the 20-MST were 0.691 (p < 0.001), 0.486 (p < 0.001) and 0.608 (p < 0.001), respectively. The highest correlation coefficient was between the VO2max estimated by the 20-MST and Cureton’s equation. Similarly, the highest correlation coefficient (r = −0.779) was between the 1-mile run time and the VO2max estimated by Cureton’s equation.ConclusionsWhen analysing more vigorous exercise than sub-maximal exercise, we suggest that Cureton’s equation be used to predict the VO2max from 1-mile run/walk performance in large numbers of healthy individuals with high VO2max. This research compares the use of 3 different formulae to estimate VO2max from 1-mile run/walk performance in male law enforcement officers aged 20–23 years for the first time and reports the most accurate formula to use when evaluating aerobic capacities of large numbers of healthy individuals.
