About this study
Official title: Effects of Low Resistance Venous Blood Flow Restriction Training (LR-VBFRT) on Biceps Brachii Muscle Performance
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.
Read the 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Low Resistance training with venous blood flow restrictionOther
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

Questions about this trial
What is this clinical trial studying?
A study testing Low Resistance training with venous blood flow restriction and High Resistance training in people with Muscle Weakness Condition, run by Riphah International University at 1 site in Pakistan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 22 Jan 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Pakistan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Muscle strength (time frame: Baseline). The study lists 10 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04181671, which also lists 5 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Jan 2020.
