The effect of method of instruction given on muscle activation and kinematic during vertical and horizontal based strength training

Abstract

Lunge and squat exercises are two exercises mainly used in strength training due to its multi-joint, structural and free weights nature and benefits. Main aim of this study is to determine the effect of verbal and video-based mode of instructions on both exercises. Joint angles and muscle activation were measured as an indicator or determinants of the effect of the exercises. Thirty male participants were recruited and involved in two testing occasions. Results of the study indicated no significant differences for both exercises in term of all determinants measured. As a conclusion, mode of instructions may give variety to teaching and learning approach for both exercises, but it produces similar effects. Most important is to ensure in any mode of instructions utilized, the technical aspects given are based on correct biomechanical ques for optimal mechanical effect.
