The objective of this research was to scrutinize the impact of three resistance-training programs on absolute and reciprocal durability and muscular strength. Forty-three male subjects were assigned to three groups: high resistance-low repetition group (HRLRG, n=15) performed 3 sets of 6-8 RM (repetition maximum) each session, the medium resistance-medium repetition group (MRMRG, n= 16) performed 2 sets of 30-40 RM per session and the low resistance-high repetition group (LRHRG, n= 12) worked out a set of 100-150 RM per session. The training for the participants was bench press thrice a week for nine weeks. The data revealed an improvement of 20% in maximal strength of the HRLRG and this was greater than 8% and 5 % improvements recorded for MRMRG and LRHRG, respectively. Regarding the absolute endurance, the trends however were reversed as LRHRG registered gains of 41%, MRMRG improved by 39% and HRLRG gained only 28%. The results for relative endurance assessment reported that HRLRG’s accomplishments essentially was declined by 7 % after training and was considerably inferior to the 22 % and 28 % improvements achieved by other two groups. It was established that skeletal muscles make general and specific modifications to a training stimulus and the stability of these adaptations is primarily reliant upon the intensity and duration of the training protocol.
