A STUDY OF PHYSIOLOGICAL-RESPONSES DURING MATCH PLAY IN INDIAN NATIONAL KABADDI PLAYERS

Objective-To determine the physical and physiological profile of kabad di players and the physiological demands of playing a kabaddi match. M ethods-Maximum aerobic capacity (VO(2)max), maximum ventilation (V(E)m ax), O-2 pulse, respiratory equivalent (RE), maximum heart rate, and O -2 debt were assessed on 16 players. The somatotype of the players was calculated by the Heath and Carter method. Heart rate was monitored d uring a selection trial match on eight players who represented India i n the Asian Games, 1994. From the playing heart rate, oxygen consumpti on (VO2) was computed through a heart rate v VO2 regression equation. Maximum lactate was evaluated from the blood samples collected at the end of the match. Results-The average heart rate and oxygen consumptio n during the match were 146.5 (SD 9.25) beats min(-1) and 2.25(0.59) l itre min(-1) respectively. During raiding the maximum heart rate attai ned varied from 162.4(11.3) to 177.4(4.2) beats min(-1). Out of 40 min of match play a raider raided on average on 8.13(2.03) occasions. The average time per raid was 20.8(6.26) s. The match heart rate and oxyg en consumption was 72.3-83.3% of the maximum heart rate, and 43.5-70.5 % of VO(2)max respectively. Maximum lactate at the end of the match wa s 6.13(2.53) mmol Kabaddi players had the somatotype of 2.68-4.71-1.83 , with absolute back strength of 175.0 kg. VO(2)max and O-2 debt were 3.59(0.36) litre min(-1) [47.82(3.68) ml kg(-1) min(-1)] and 5.3(1.85) litres (70 ml kg(-1)) respectively. Conclusions-Kabaddi is an intermi ttent sport. The rest pause during the game is sufficient for recovery . During raiding the main source of energy is anaerobic.
