Anthropometric profile, body composition and somatotyping of national Iranian cross-country runners

Abstract: This study was conducted to determine the anthropometric profile of selected national athletes. The purpose of this study was to find out anthropometric measurements, body composition and somatotyping of Iranian cross-country runners. The participants were 9 male national Iranian cross-country runners. The age of athletes was between 20 to 32 years. Cross-country personal best 36min 55s (47s); training volume: 120-180 km.wk; All subjects were assessed for height, weight, breadths, lengths, girths and skin-fold thickness. Percentage of body fat was calculated from the sum of 7 measurements of skin-fold thickness. The somatotype and height to weight ratio (HWR) as well as the skin-folds extremity to trunk ratio (E:T) were also calculated. The Mean (SD) of LBM (Lean Body Mass), %BF (Body Fat), WHR (Waist Hip Ratio), HWR (Height to Weight Ratio), E:T (Extremity/Trunk) skin-fold ratio, SAD (Somatotype Attitudinal Distance) and Manourrier were 60.36 (8.25), 8.07 (1.71) %, .82 (.06), 44.01 (1.00), .77 (.17), 0.90 (0.33) and 1.10 (.63), respectively. The Mean (SD) endomorph, mesomorph and ectomorph were 1.43 (.43), 4.10 (.56), and 3.63 (.73), respectively. National Iranian cross-country runners seem to have mesomorph and ectomorph are equal (or do not differ by more than one-half unit), and endomorph is smaller. Despite population comparisons would be required to identify any connection between specific anthropometric dimensions, these reference data reported in the present study for useful to practitioners and researchers, carry immense practical application and should be useful for future investigation on endurance runners selection, talent identification in cross-country running and training program development.

Leisure Boredom Scale: the Factor Structure and the Demographic Differences

Abstract: The purpose of this study was to investigate the reliability and validity of the Turkish version of the Leisure Boredom Scale (Iso-Ahola & Weissinger, 1990) for adults in Turkey. The second purpose was to investigate the differences based on demographic variables (gender, marital status, working sector) regarding leisure boredom. In total 312 employees from public and private sectors (167 female, 145 male) residing in Ankara participated in this study. Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were conducted to test the structural validity of the scale. EFA demonstrated that this scale yielded two subscales in the Turkish version. The first factor was named "boredom" and the second factor was named "satisfaction" by the participating researchers after reviewing the related literature and examining the factor structure of the scale. The scale consists of 10 items; the item factor loadings for the overall scale range between 0.38 and 0.83; and the Cronbach Alpha coefficient for the subscales was determined 0.72 for boredom and 0.77 for satisfaction in the final form of the scale. According to t-test results regarding the demographic variables, there was statistically significant difference in gender only in the ‚satisfaction‛ subscale, and between women and men participants, with men participants having higher mean scores (p<.01). There was no significant difference in terms of marital status in total LBS and the subscales. Concerning the working sectors of the participants, the analysis showed significant differences in total LBS and the ‚boredom‛ subscale between public and private sector’s participants, with public sector’s participants having higher mean scores than the latter (p<.01). In conclusion, the results of the research demonstrated that the Turkish adaptation of ‚The Leisure Boredom Scale‛ can be used as a valid and reliable measurement tool to examine and evaluate the leisure boredom levels of Turkish adults. Another conclusion of the study worth noting is that there were significant differences between the different components of gender and working sector variables in terms of leisure boredom levels.

Relationship between core stability, dynamic balance and jumping performance in soccer players

Abstract: The purpose of this study was to investigate relationship between core stability, dynamic balance and jumping performance in soccer players. Seventeen male soccer players (mean ± SD: age, 21.06 ± 1.71 years) participated as volunteer in this study. Dynamic balance of the participants were evaluated at directions of anterior (A), posteromedial (PM) and posterolateral (PL) with Star Excursion Balance Test (SEBT). The core stability was evaluated with trunk flexion, side bridge, and trunk extension tests. For jumping performance, squat jump height was measured using a contact mat. There was a negative correlation (r = -0.705) between trunk flexion test and squat jump height ( p 0.05). There was no significant correlation between trunk flexion, side bridge, trunk extension tests and SEBT values ( p > 0.05). The results of this study suggest that trunk flexion is associated with squat jump height in soccer players, but not side bridge and trunk extension tests. The core stability does not contribute significantly on dynamic balance.

Effect of jogging and core training after supramaximal exercise on recovery

Abstract: The aim of this study is to compare the effect of jogging and core training after supramaximal exercise on recovery. 30 male basketball players (age; 23,57±1,32 years) playing in the regional basketball league participated the study. Subjects were required to visit the laboratory on 2 occasions, each separated by 3 days for recovery by 2 different methods. Subjects performed jogging or core training after Wingate Supramaximal Exercise (WSE) for recovery. The order of the 2 different recovery methods (jogging and core training) was selected randomly to prevent an order effect. Resting Heart Rate (HR) and blood lactic acid (LA) values of subjects were measured and then they performed WSE. Following the test, LA measurements were repeated in the 1 st min, 5 th min and 10 th min of recovery. HR was measured right after the test and at the every 1 minute of 10 minutes recovery. LA values were not found significantly different between two recovery methods (p>0.05). It was determined that all HR values except resting, right after, 4 th , 7 th and 9 th min of recovery with core training was significantly lower than the same minutes of recovery with jogging (p<0.05 and p<0.01). It was determined that the effect of jogging and core training on recovery LA level, carried out after supramaximal exercise were not different but they were different on recovery HR. It was determined that core training lowered HR faster.

Comparison of Gross Motor Development of 3-7 Years Old Children in Different Geographical Regions

Abstract: This study was carried out to determine whether gross motor development of 3-7 years old children differed according to their geographical regions. 131 children from the Mediterranean Region, 149 children from the Southeastern Anatolia Region, 214 children from the Marmara Region, 107 children from the Aegean Region, 114 children from the Black Sea Region, 161 children from the Central Anatolia Region, 115 from the Eastern Anatolia Region children were included in the study. Of the children participating in the study, 475 were girls and 516 were boys. In order to collect data, Test of Gross Motor Development-Second Edition (TGMD-2) was used. Kruskal Wallis H test was used to compare locomotor, object control and gross motor total test scores of the three, four, five, six and seven age groups children according to the geographic regions. The results of the analysis showed that locomotor subtest scores of children aged 5 and 7 years were differentiated according to their geographical regions. Mann Whitney U test was used to determine the difference between the two groups. As a result of the paired comparisons, locomotor subtest scores of children in five age group living in Black Sea Region were found to be significantly lower than locomotor subtest scores of children living in Southeast Anatolia, Marmara and Central Anatolia Regions. The locomotor subtest scores of the children seven age in the Black Sea Region were significantly higher than the locomotor subtest scores of children living in Southeast Anatolia and Eastern Anatolia Regions. In addition, it was determined that gross motor total test scores of the children of seven age groups differed according to the geographical region. As a result, gross motor total test scores of children in seven age group living in the Black Sea Region were found to be significantly higher than the gross motor total test scores of children living in Eastern Anatolia.
