Resistance training has been widely recognized as an effective stimulus for increasing skeletal muscle size and strength. This study intends to compare the effects of high resistance training without blood flow restriction and the low resistance training with blood flow restriction training on bicep muscle performance.
The study is Randomized Control Trail, which is being conducted in RIPHAH COLLEGE OF REHABILITATION SCIENCES. Sample size of 40 individual was calculated using Epitool with 95% confidence interval (CI) and power 80%. Individual will be screened out according to inclusion criteria. Individuals will be allocated randomly into two groups, 20 in high resistance training group and 20 in low resistance training with blood flow restriction group by sealed envelope method. High resistance training will be use in control group.Low resistance with blood flow restriction training will be used in experimental group. Assessment will be done on baseline 2-4 days prior to the intervention and after 8 weeks of training. Data will be analyzed on SPSS version 21.

Total 20 males will participate in this group after warmup , Blood flow restriction will be provided through sphygmomanometer optimum pressure will be measured through following formula occlusion pressure (mmHg) = 0.514 (SBP) + 0.339 (DBP) + 1.461 (Arm circumference) + 17.236 then 30% of 1RM will be used for training . The standard protocol will be used which is four sets (1st set-30 repetitions, 2nd set-15 repetitions, 3rd set-15 repetitions, and 4th set-15 repetitions) with 30-60 s of interval between sets. ( the cuff must be deflated between sets of exercise) for 8 weeks (24) sessions on non-consecutive days. participants will be re-assessed for all baseline variables after 8 weeks of training biceps curls will be used for training. Heart Rate and oxygen saturation will be measured during the session through Pulse oximeter
Total 20 males will participate in this group after warm up. 80% of 1RM will be used for training, 3 sets of 8 repetitions will be used with 30-60 s of interval between sets. for 8 weeks (24) sessions on non-consecutive days.No blood flow restriction will be applied to this group Participants will be re-assessed for all baseline variables after 8 weeks of training. Bicep curls will be used for training.

1 Repetition maximum
1RM will be assess using Epley's formula of 1RM , RM= w(1+r/30) where "w" is the sub maximal weight and "r" is repetition then percentages of 1RM will be used for training purposes 80% of 1 RM for control group and 30% of 1RM for experimental group.

Bicep Muscle power
Muscle power will be assesses of all the participants using power formula(Power= W/t= FS/t) for that force (F) will be assessed through dynamometer in newton covered distance (S) will be taken as covered range of motion and will be asses through goniometer (elbow flexion in supinated position). Time (t) will be calculated using stop watch

Bicep muscle endurance testing
Bicep muscle endurance will be calculated prior to the intervention by asking participants to lift light -moderate weight and perform bicep curls in supinated position the total number of repetition they will perform doing complete eccentric and concentric movement of the muscle will be taken as the endurance of the bicep muscle
