摘要: Abstract Twenty young adults (ten males − mean age = 21.1 years; ten females years) were tested for their two-handed push-pull strength in sagittal plane at heights of 35 cm (low), 100 (medium) and 150 (high) isometric isokinetic modes. The lower extremities the subjects stabilized a custom-designed device hip, knees ankle. twelve experimental conditions (2 activities push pull × 3 2 modes) randomized. strengths measured using modified Static Dynamic Strength Tester with SM 500 load cell. analogue data sampled collected 50 Hz through Metrabyte DAS 20 an IBM XT. Males as well strongest pulling medium height mode. pushing ranged between 41% to 68%, 27% 44% respectively when normalized against height. invariably significantly than (p
