RELATIONSHIPS OF MECHANICAL POWER TO PERCEIVED EXERTION AND VARIOUS PHYSIOLOGICAL PARAMETERS MEASURED IN ELITE YOUTH DISTANCE RUNNERS AND CONTROLS

##article.abstract##

In many studies of human movement, calculations of mechanical energy and physiological energy costs of exercise (Aleshinsky, 1986; Bhambhani & Singh, 1985; Cavagna, Thys & Zamboni, 1976; Robertson & Winter, 1980; Pierrynowski, Winter & Norman, 1980; Saito, Ohkuwa, Ikegami & Miyamura, 1983; Sakurai & Miyashita, 1985; Williams & Cavanagh, 1983; Williams, 1985; Winter, Quanbury & Reimer, 1978; Zurrugh, 1981) have been used as tools to describe and compare performance. The purpose of the present study was to expand upon these comparisons by drawing relations between mechanical power and ratings of perceived exertion as well as relations between mechanical power and physiological costs of exercise.
