Relationships of Strength and Anthropometric Measures to Physical Performances Involving the Trunk and Legs

Abstract In this study, 16 strength and 10 anthropometric tests were related by correlational methods to 8 trunk and leg measures, involving dynamometric strength, muscular endurance, agility, and power. The intercorrelations among some of the anthropometric variables were especially high: .91, standing height with leg length; .88, foot length with leg length; and .87, body weight with both hip width and thigh girth. The highest strength test intercorrelation was .65 between trunk flexion and extension. Significant multiple correlations obtained were: .74 for leg lift with body weight, ankle dorsal flexion strength, and trunk flexion strength; .71 for back lift with knee extension strength, hip width, trunk flexion strength, and knee flexion strength; and .66 for standing broad jump with adipose tissue over the abdomen (negative) and hip extension strength (positive).
