The purpose of this research was to identify the relationship between jump test results and acceleration phase of sprint performance in national and regional 100m sprinters. Fifteen male (age 21.89 ± 3.26 years; body height 1.72.66 ± 3.20 m; body mass 61.35 ± 11.40 kg; 100 m personal best: 11.67 + 0.46 s {11.00 - 12.19}) track sprinters at a national and regional competitive level performed 10 m sprints from a block start. Anthropometric dimensions, along with squat jump (SJ), countermovement jump (CMJ), continuous straight legged jump (SLJ), single leg hop for distance, and single leg triple hop for distance measures of power were also tested. Pearson correlation analysis revealed the single leg hop for distance with front and back leg (respectively, r = -0.74 and r = -0.76; p = 0.021 and p = 0.017), and the single leg triple hop for distance with front and/or back leg (respectively, r = -0.84 and r = -0.89; p = 0.004 and p = 0.001), generated capabilities to be strongly related to sprint performance. Further linear regression analysis predicted an increase in the single leg hop for distance with front and back leg of 10 cm, to both resulted in a decrease of 0.07 s in 10 m sprint performance. Further, an increase in the single leg triple hop for distance with front and/or back leg of 10 cm was predicted to result in a 0.08 s reduction in 10 m sprint time. The results of this study seem to suggest that the ability to gain more distance with the single leg hop and the single leg triple hop for distance to be good indicators for predicting sprint performance over 10 m from a block start.

Study aim: To investigate some anthropometric characteristics of male and female kayakers of four competitive categories.Material and methods: Anthropometric characteristics of 83 kayak athletes were measured during the 2009 Greek Cup. Kayakers were divided into four groups according to their competitive category: Women (n = 13; mean age 22.7 ± 3.1 years), Junior Female (n = 15; mean age 16.2 ± 1.1 years), Men (n = 27; mean age 23.7 ± 4.6 years) and Junior Male (n = 28; mean age 16.3 ± 1.2 years).Results: In both groups, the BMI, lean body mass, and relaxed and flexed arm girth were significantly different with respect to age group; body mass was significantly different, but only in male groups. No differences were found between groups on body fat.Conclusions: The data provided in this study could be used as a guideline for talent identification from the general population and may help coaches establish a specific kayak anthropometric profile in order to distinguish an elite kayak athlete.

Study aim: To assess the handgrip strength in Indian university softball players as dependent on selected hand-anthropometric variables.Material and methods: Indian university softball players (121 males and 122 females) and untrained controls (98 males and 102 females) aged 18 - 25 years participated in the study. The following variables were recorded: body height and mass, BMI, right hand width and length, lengths of the right 2nd, 3rd and 4th digits and right handgrip strength.Results: One-way ANOVA showed significant differences (p<0.05 - 0.001) in all the characteristics studied, except body height, right hand length and right 2nd digit length among these four sets of data. The right handgrip strength was significantly correlated (p<0.01 - 0.001) with all the variables studied. Both in male and female softball players, the partition of R2 into the contributions of individual independent variables revealed that body height (18%), hand width (11%), body mass (8%) and hand length (5%) significantly contributed to the total variance (44%) of handgrip strength.Conclusions: The data might be useful in selecting players and in talent identification for softball.

The aims of this study were to describe kinanthropometric characteristics of elite male and female young paddlers and to compare their proportionality with Olympic paddlers. One hundred and eighty seven young elite sprint paddlers (124 males and 63 females), aged 13 and 14 years, were assessed using a battery of 31 anthropometric dimensions. Somatotypes, Phantom Z-scores and corrected girths were calculated. Comparison between the 13 and 14 year old paddlers showed that 14 year old males had greater height, body weight, sitting height, arm span and upper body lengths, breadths and girths than their 13 year old counterparts, whereas 14 year old female paddlers only differed significantly from the 13 year olds in biacromial breadth and corrected arm girth. Mean somatotypes of male paddlers were best described as balanced mesomorphs, while female paddlers were centrals. Olympic paddlers had higher proportional dimensions in upper body girths, and biacromial breadth in both genders. The data provided in this study could be used as a guideline for talent identification in sprint canoeing and kayaking.

Introduction: Because of the fact that detailed data on the physiological characteristics of Pencak Silat are still limited. The primary purpose of this study to assess the physiological responses of Pencak Silat athletes and a secondary aim is to compare the physiological responses of Pencak Silat athletes with physiological responses of Taekwondo athletes. Material and Methods: This study has included 17 male junior martial art athletes (aged 15-16 years). This study requires all participants to completed one familiarization session and two experimental sessions. During the first session (laboratory condition), anthropometry was measured in the laboratory, and during the second session (on-court condition), the participants completed tests for anaerobic capacity (sprint test 60-m, vertical jump, push-ups, and sit-ups) and VO2max test. Results: The statistical analysis revealed no significant differences in anthropometry, vertical-jump, sit-ups, push-ups, and 60-m sprint results among TKD and PKS groups. Furthermore, the TKD group had significantly higher VO2max (p=0.015), when compared with the PKS group. Conclusion: The present investigation describes similar physiological characterizes, such as weight, height, BMI, BMR, body fat and also performances of vertical jump, situps, push-ups, and 60-m sprint tests among Taekwondo and Pencak Silat athletes. However, in comparison with junior Pencak Silat athletes, the junior Taekwondo athletes have better VO2max.

B cell activation factor (BAFF) is a recently discovered member of the TNF ligand superfamily secreted by adipocytes, previously linked to autoimmune and lymphoproliferative disease. The aim of this study was to investigate the relationship between BAFF plasma levels and the non-modified, usual dietary composition as well as obesity-related anthropometric parameters in a cohort of 58 obese and non-obese Central-European Caucasian individuals. We found that BAFF had an independent predictive role for percentage of body fat; moreover, BAFF levels were correlated with waist and hip circumference. BAFF plasma levels were also significantly correlated with investigated dietary composition based on the 7-day food records, as the BAFF levels correlated with the percentage of energy derived from the carbohydrates and with energy derived from the dietary fat. Our results suggest that BAFF may play a role in linking the immune status and metabolic response to diet.
