Relationship among Speed, Power ＆ Fatigue Index of Cricket Players

Objective: The purpose of this study was to observe speed, power and fatigue index of under 19 year cricket players. The design of this study required participants to perform six sprints each of 35 meter. Thirty one (N=31) trained male cricketers between the ages of 15 and 19 years volunteered for this study. The mean age, height and weight of cricketers were 16.81 +/- 1.13years, 172.23 +/- 6.85cm and 61.33 +/- 8.93Kg. The mean sprint time of -1st, 2nd, 3rd, 4th, 5th and 6th of cricketers were 5.39 +/- 0.34 seconds, 5.53 +/- 0.31 seconds, 5.61 +/- 0.36 seconds, 5.85 +/- 0.26 seconds, 5.94 +/- 0.25seconds and 6.07 +/- 0.17 seconds respectively. The mean power of -1st, 2nd, 3rd, 4th, 5th and 6th sprints of cricketers was 491.00 +/- 105.90 watts, 454.90 +/- 94.81watts, 435.23 +/- 90.49 watts, 382.84 +/- 78.54watts, 364.68+/- 78.62watts and 339.94 +/- 58.96watts respectively. The maximum power, minimum power and average power of cricketers was 511.55 +/- 94.97watts, 333.71 +/- 65.83watts, and 411.42 +/- 73.59 watts respectively. It was concluded from the results of this study that sprint time and power decline in cricketers may be due to the reduced energy production via anaerobic glycolysis and muscle acidosis.
