The purpose of this study was to investigate the effectiveness of training with weighted chains in comparison to traditional resistance and plyometric exercise modes. Twenty-two (n = 22) sports performers with previous resistance training experience completed the study. The participants were divided across three groups and trained twice per week for four weeks. The weighted chain and traditional resistance treatments worked at specified percentages of one-repetition maximum, whilst the plyometric sample used body-weight only. All subjects performed a pre- and post-test three-repetition maximum squat, an unloaded countermovement jump and a loaded squat jump. These represented lower-body strength and power respectively. Analysis of covariance tests were performed on the data. Significance was set at α = 0.05. Results indicated significant improvements in the weighted chain and traditional resistance groups for three-repetition maximum scores compared to plyometrics. There were no other significant difference values, although the weighted chain intervention demonstrated the largest improvement across the entire testing battery. The results suggest variable resistance training could be a useful technique for strength and power development in this population. It should be emphasised that the peak power output scores improved non-significantly, and that more research is required before this training type can be strongly recommended.
