About this trial

The primary objective of this prospective study is to investigate the effects of Blood Flow Restriction (BFR) training compared to traditional low-weight resistance training on grip strength in young adults.

Despite the growing interest in BFR training and its potential benefits, there is limited research specifically investigating its impact on grip strength. Understanding the effects of BFR training on grip strength could have significant implications for individuals seeking to optimize their grip performance, rehabilitation settings, and sports performance enhancement. Additionally, examining the safety and efficacy of BFR training for this specific outcome will contribute valuable insights to the scientific community.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Participants must be between 18 and 35 years old at the time of enrollment.

Disqualifiers

Participants with a history of cardiovascular disease (e.g., heart disease, hypertension), musculoskeletal injuries (e.g., fractures, dislocations), or neurological disorders (e.g., neuropathy) that could affect exercise performance will be excluded.

Trial design

Design model

Parallel

Treatments tested in this trial

Blood flow restriction
Other intervention
Both groups will undergo a 6-week training intervention with training 2x a week, after which grip strength and other relevant outcomes will be measured and compared. Exercise sessions will be at least 48 hours apart. Participants will be allowed to continue with their normal exercise routine outside of the study.

Treatment groups

Group B: No Blood flow restriction group which just does LWRTNo intervention 0 interventions

Trial outcomes

Primary outcomes

Grip Strength

Isometric grip strength will be assessed in the dominant arm after the intervention using the Jamar hydraulic hand dynamometer (Lafayette Instruments, Lafayette, IN). Participants will be positioned in sitting with the knees and hips flexed to 90 degrees and feet flat on the floor. The shoulder will be in a neutral position with the elbow flexed to 90 degrees and the forearm in neutral pronation-supination. (Crotin \& Ramsey, 2021) The participant will be instructed to squeeze the dynamometer with maximal effort for 3 seconds while receiving verbal encouragement. A total of three repetitions will be completed with a 30 second rest between trials to reduce fatigue. (Crotin \& Ramsey, 2021) The peak grip strength value of all three trails will be used for baseline strength and 30% of the peak value will be used to calculate the resistance (in lbs.) for the exercise protocol.
