Low Resistance Venous Blood Flow Restriction Training (LR-VBFRT) on Biceps Brachii Muscle Performance

Not Applicable

Completed

• Conditions: Muscle Weakness Condition
• Interventions: Other: High Resistance training; Other: Low Resistance training with venous blood flow restriction

• Registration Number: NCT04181671
• Lead Sponsor: Riphah International University

Brief Summary

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.

Detailed Description

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.

Arm && Interventions

Group	Intervention	Description
High Resistance Training Group	High Resistance training	Participants of this group will receive High resistance training (80% of 1 RM) without blood flow restriction.
Low Resistance Training Group	Low Resistance training with venous blood flow restriction	The experimental group will receive low resistance blood flow restriction training with 30% of 1 RM.

Primary Outcome Measures

Name	Time	Method
Muscle strength	Post 6 weeks	Handheld dynamometer will be used for measuring muscle strength of bicep muscle of all participants by single examiner
Arm circumference	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	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	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	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
