The comparison of two protocol of resistance exercise on upper and lower body muscles strength

The objective of this study is to compare two common ways of training including weight training and elastic bandweight training in enhancing the upper and lower body parts. Thirty young untrained men (with the age, height, weight and body fat mass of 22.1±2.4 yr,174.8±4.1 cm, 72.2 ± 3.1and %18.2± 1.3respectively) were randomly divided into two groups training with free weight (WT) and elastic band-free weight (BWT).They started their eight weeks training with70-80% of one repetition maximum (1RM)and 6-10 repetitions. Their level of strength in exercises like bench press, triceps curl, shoulder press and squat were measured before and after these eight weeks, after that the acquired measures were assessed through T statistics which revealed a considerable amount α≤ 0.05.Both groups underwent a distinctive change in their strength level in the aforementioned exercises (%22.51 increase in group WT and %23.56 in group BWT),although the difference was not significant. These results showed that the improvement in strength levels for untrained men through weight training or the band-free weight are the same so it is recommended for the beginners to start with the free weights
