Weight training--Physiological aspects; Oxygen consumption (Physiology);
Heavy resistance and low resistance weight training methods are commonly used in off season conditioning programs for various sports. Research has indicated that heavy resistance training elicits muscular strength development whereas low resistance training elicits the development of muscular endurance. However, there is very little or no research which has investigated a comparison of oxygen consumption between heavy resistance and low resistance training while keeping work constant.
The purpose of this investigation was to compare the oxygen cost of performing heavy and low resistance weight training methods. Also, a second purpose of the study was to determine the contribution of the concentric phase to total O2 cost during low resistance weight training. Twelve males moderately experienced in weight training participated in the study. Three treatments were employed in the study. Each subject performed at 80% of their one repetition maximum for six repetitions (heavy resistance training), 40% of their one repetition maximum for 12 repetitions (low resistance training) and 40% of their one repetition maximum for 12 repetitions performing only the concentric phase. The results indicated that there was a significantly higher (p < .05) oxygen consumption for the heavy resistance method than the low resistance method and the low resistance method using both concentric and eccentric movements exhibited a significantly higher (p < .05) oxygen consumption than the concentric only low resistance method. The results also indicated that the majority of difference in O2 cost between the heavy and low resistance methods could be accounted for during the recovery periods. Heavy resistance training was also significantly higher than the low resistance method for ventilation, respiratory exchange ratio and time to recovery, while there was no significant difference in heart rate. Therefore, it would seem that the heavy resistance training method is physiologically more demanding than low resistance training even if total work is held constant.
