The purpose of this study was to determine the effects of short-term equal-volume isotonic training with different workout frequency on upper body, lower body, and muscle girth in male volleyball players. Thirty male volleyball players were randomly selected from Govt. Degree College Killam, affiliated with Kashmir University (UT) Jammu and Kashmir with mean ± SD: (19.45 ± 3.4 years, height of 177.18 ± 4.15 centimetres, 66.70 ± 5.30 kg and BMI 21.20 ± 3.25 were chosen). The subjects were segregated into three groups; total-body isotonic training, (12 exercises for two sessions per week) (Isotonic G-I=10), upper-body, and lower-body isotonic training (12 exercises for three sessions per week) (Isotonic G- II=10), and control group (CG=10) didn’t take part in any special training. Assessments of body composition, height, weight, body mass index, and flexed arm girth, strength (one repetition maximum in bench press) and vertical jump were determined before and after 8 weeks of training. Flexed-arm, 1-RM bench press and vertical jump was improved significantly in all training groups (P < 0.05). All groups increased body weight and body composition (P ≤ 0.05), but isotonic G-I group showed a little improvement rather than other isotonic G-II. It is concluded that in healthy young men, whole and split weight training routine produce similar results over the first 2 months of training, with minimal differences among groups.

Key Words: upper body, lower body, flexed-arm girth, isotonic training and volleyball.
