Handgrip Training With and Without Blood Flow Restriction in Relation to Gender Among Healthy Young Adults

Study Overview
=================
Brief Summary
-----------------
In this study Investigator will determine the effects of blood flow restriction training on hand grip strength using hand held dynamometer among healthy young adults and investigator also see effects of blood flow restriction training on forearm circumference using weighted measuring tape among healthy young adults along with correlation of male and female population following blood flow restriction training among healthy young adults.

Detailed Description
-----------------
(A randomized control trial will be conducted in Foundation University Institute of Rehabilitation Sciences on 56 healthy young adults. Study will be conducted in 6 months (May 2020 to December 2020). Healthy young adults of both genders between 20-40 years of age will be included in the study. Adults with any diagnosed cardiovascular, metabolic, orthopedic or neurological disease, active/ongoing infection, recent history of upper extremity fracture or history of vascular medication will not be included in this study. The outcome variables will be hand grip strength measured through hydraulic hand held dynamometer and forearm circumference through anthropometric measuring tape.After assessment and screening, subjects will be randomly allocated in Control group A receiving low intensity strength training and Interventional group B receiving blood flow restriction training along with low intensity strength training via lottery method.Each participant will receive three sessions per week for two consecutive weeks making 6 treatment sessions in total. The outcome variables will be assessed at the start of 1st session and then at 6th session. To carry out the anthropometric assessment, anthropometric tape for circumference measurements, a digital scale for measuring weight and a stadiometer to measure height will be used.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Handgrip strength training with Blood flow restriction<br>Three sessions per week will be given to individual subject. and training will be with Blood flow restriction. Subjects will be followed for two weeks for; Hand grip strength Forearm circumference | Other: Handgrip strength training with Blood flow restriction<br>* Participants of this group will get exercise training through hand grip strengthener and DMOOSE fitness resistance bar. Participants will contracts his/her forearm at a rate of 15 times/min (1 contraction every 4 sec). The subjects will train for 20 min, 3 days per week for 2 weeks (total 6 sessions), under the supervision of a principle investigator. Participants will be allowed to take 1 min rest periods, after the completion of 5 minutes of training. However, for one of the limbs the pneumatic blood pressure cuff will be placed on the upper arm, 4 cm proximal to the ante-cubital fossa. The decision which arm would receive the occlusion during training will be randomized to avoid a dominant or non-dominant hand bias. During experimental group training blood pressure cuff will be partially inflated (80 mmHg) to ensure venous occlusion. Participants will be allowed to take 1 min rest periods, after the completion of 5 minutes of training while the cuff remained inflated.<br>|
| Active Comparator: Handgrip strength training without Blood flow restriction<br>Three sessions per week will be given to individual subject and training will be without Blood flow restriction. Subjects will be followed for two weeks for; Hand grip strength Forearm circumference | Other: Handgrip strength training without Blood flow restriction<br>* Participants of this group will get exercise training through hand grip strengthener and DMOOSE fitness resistance bar. Participants will contract his/her forearm at a rate of 15 times/min (1 contraction every 4 sec). The subjects will train for 20 min, 3 days per week for 2 weeks (total 6 sessions), under the supervision of a principle investigator. Participants will be allowed to take 1 min rest periods, after the completion of 5 minutes of training.<br>|
