简要总结
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.
详细描述
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.

结局指标
主要结局
Muscle strength
时间窗: Post 6 weeks
Handheld dynamometer will be used for measuring muscle strength of bicep muscle of all participants by single examiner
Arm circumference
时间窗: Post 6 weeks
arm circumference will be measured in centimeters at the midpoint between the acromion process and the center of the elbow(by measuring tape)
1 Repetition maximum
时间窗: Post 6 weeks
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
时间窗: Post 6 weeks
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
时间窗: Post 6 weeks
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
