Anthropometric and physiologic properties have influence on exercise performance in sepak takraw and physiological profiles of athletes differ between sports and playing positions.

Present study was aimed to determine the effect of playing position on anthropometric, body composition and physical fitness parameters in young male sepak takraw players.

The cross-sectional study was conducted on three positional groups of total 44 male Indian sepak takraw players (spiker/killer, n = 14; tekong, n = 14; and feeder, n = 16) of national level. Anthropometric parameters, body composition profile, physical fitness variables including 30m flying, 6X10m shuttle run, vertical jump, sit up, endurance and anaerobic power were assessed by following standard protocols.

Significant differences were observed in height, weight and leg length among the positional groups. Almost all body composition parameters were significantly (P < 0.01) higher among ‘tekong’ position except fat mass. Handgrip strength, back strength, vertical jump, sit up, VO2max, explosive leg power and maximum anaerobic power were found to be significantly differed among the three positional groups of sepak takraw. Regression prediction model identified back strength (P = 0.034), peak explosive power (P < 0.001) and leg length (P < 0.001) as the significant predictor of vertical jump (R2 = 0.930 and P < 0.001).

Players of ‘tekong’ position were better in anthropometric and body composition profiles than ‘spiker and feeder’. Whereas, ‘spiker’ position was found to have higher back strength, explosive power, vertical jump and sit up abilities. Regression model identifies back strength, peak explosive power and leg length as the significant predictors of performance in sepak takraw.

Scientific researches available on anthropometric and physiological characteristics of female rugby players in India are very scanty.

The present study was aimed to evaluate and compared different anthropometric, body composition and physical fitness parameters and also to investigate whether any distinctive characteristics exist among above variables according to their specific playing position.

Twenty five Indian national women rugby players (forward, n = 12, mean age = 20.9 ± 3.30 and back, n = 13, mean age = 19.7 ± 2.48) of pre-competitive phase were chosen as subject from the national coaching camp. They were evaluated for various anthropometric, body composition parameters, hemoglobin, blood glucose level and physical fitness profile by following standard procedure.

Forward players had significantly higher body weight, BMI, fat percentage, sum of skinfold, total body potassium, total body calcium and glycogen content as compared to the back. Whereas, players of back position had significantly higher relative muscle mass (MM/Wt.), relative body cell mass (BCM/Wt.), agility, standing broad jump, VO2max and relative peak anaerobic power than their forward counterparts. Linear regression model identified agility (β = 0.59) and sum of skinfold (β = -0.45) as significant predictor of peak anaerobic power (adjusted R2 = 0.61) of these players.

Present study indicated the players of back position were faster, more agile and aerobically fit with having lower body weight and fat percent as compared to their forward counterparts. Whereas, principal component analysis identified BMI, sum of skinfold and agility as the main confounding variables to categorize the present rugby players between forward and back positional groups.
