HEAVY-RESISTANCE TRAINING DOES NOT IMPROVE SEATED SHOT PUT POWER
Mayhew, J. L., Ware, J. S., Johns, R. A., & Bemben, M. G. (1997). Changes in upper body power following heavy-resistance strength training in college men. International Journal of Sports Medicine, 18, 516-520.
The effects of heavy-resistance training on measures of bench press power using absolute loads and seated shot put performance were measured. College men (N = 24) trained twice weekly for 12 weeks. Bench press power was measured by timing free weight actions at 30%, 40%, 50%, 60%, 70%, and 80% of 1 RM.
1 RM performance increased significantly (9.1%) after training. There was no change in shot put performance. Peak power was produced between 40-50% of 1 RM before and after training. There was no relationship between changes in shot put performance and changes in resistance-training strength.
Implication. Heavy-resistance training improves the activities involved in the training, such as 1 RM. Such gains are not transferred to more explosive activities. This adds support to the specific nature of resistance training and its inability to transfer to other activities.
