Correlations among Factors in Judo Contest Performance

To examine the interrelations among foot and hip reaction times, body weight, age, height, experience (1 to 12 yr. practice of Judo), belt rank, and indices of performance in a judo contest, measures were taken from 34 males, aged 15 to 40 yr. (M= 23.0). Body weight and reaction times were not consistently related to contest scores, but amount of experience and belt rank were clearly positively related (rs ranged from .76—.91).
