Abstract

The purpose of the present research was a camprision of the time to exhaustion and the biomechanical parameters in the exhaustive protocols with different intensity in the active young men. for this, thity one of the students from the branch of spysical education mohageg university with the average of(age 20/12±./71, weight 65/61±6/47, length 172/80±4/26,VO2max 61/27±3/7, BMI 21/96±1/60, fat persent 13/86±2/20) had be chosen voluntarity. By using buros test, their maximum bearbearth had be determined and they run in for different protocols of running in 70,80,90,100 percent of hearbeath on tape until they became frustrated. After any protocol, they recorded the maximum running time, the distance and speed, for dertermination of the potent output, the power, the cost of energy and consumed oxygen. For analyzing these data, by means of the statical method ANOVA, the repeated measuring and following bonfrony test had be used.the results showed that there is a meaningful difference between the potent output, of power, the cost of energy and the time of running in different intensity 70,80,90,100 percent of the maximum heartbeat and they saw the effect with a high level(P≤0/001 ES=0/999). When the action intensity increased to %10, from 70 to 80 , the volume of the running time, done work and the distance decreased to %48, the output of power increased %12 and the consumed oxygen and the cost of energy decreased to %14.while, the exercise intensity increased to %20, from %70 to %90, the volum of the running time %80, the volum of done work and the distance %73 decreased, the running speed %33, the output of power %36 the consumed oxygen %29 increased and the cost energy fell down about %74. On the, from %70 to %100, the volume of the running time %96 the volum of done work and the distance %94 decresed, the running speed %56, the output of power %40 the consumed oxygen %50 increased and the cost of energy fell down about %94 so, %92 of these trans formations in the output of exercise, the output of power, the cost of energy and the consumed oxygen in defferent protocol of running is related to the exercise intensity.
