INTRODUCTION: This thesis is focused on comparison of submaximal load PWC 170 to three different types of cranks together with contrasting various methods of calculating this index. We have chosen one method from those four, which has seemed like having the least error and we have compared it against those three remaining ones. METHODOLOGY: It has been tested on 10 probands (5 men and 5 women) which were in age range from 20 to 29 years and without any serious health problems. Graded test without breaks has been chosen for stress protocol, where every proband started with stress 1 W/kg of his weight on bycycle and eliptical crank. We have used conversion factor 0,5 on arm crank, which means that the stress on this crank started on 0,5 W/kg. The load has been gradually increasing by 0,5 W/kg on each level (0.25 W/kg on arm crank). Every level of load has three minutes duration and number of levels used has been individual because it has been driven by increase of pulse rate. After the proband has reached at least 170 beats per minute we have been continuously increasing the stress till we have reached maximum. We have determined pulse frequency during the examination on the end of each level of stress and also when the maximum has been reached, as well as subjective evaluation of load intensity on a...
