High Intensity Resistance Training With and Without Blood Flow Restriction in ACL Reconstruction

November 9, 2023 updated by: Riphah International University

Effects of High Intensity Resistance Training With and Without Blood Flow Restriction on Quadriceps Strength, Power and Agility in ACL Reconstruction Among Volley Ball Players

This study is randomized and single-blinded. Ethical approval is taken from the ethical committee of riphah international university, Lahore. Participants who meet the inclusion criteria will be enrolled in Groups A & B through the sealed envelop method by the Non-Probability Convenient random sampling technique. Group A will perform traditional High-intensity resistance training without Blood Flow Restriction training after ACL Reconstruction Surgery. Group B will perform traditional High-intensity Resistance training with Blood Flow Restriction training after ACL Reconstruction Surgery.

Detailed Description

The objective of the study is to determine the effects of high-intensity resistance training with and without blood flow restriction on quadriceps strength, power, and agility after ACL reconstruction among volleyball players. This study is randomized and single-blinded. Ethical approval is taken from the ethical committee of riphah international university, Lahore. Participants who meet the inclusion criteria will be enrolled in Groups A & B through the sealed envelop method by the Non-Probability Convenient random sampling technique. Group A will perform traditional High-intensity resistance training without Blood Flow Restriction training after ACL Reconstruction Surgery. Group B will perform traditional High-intensity Resistance training with Blood Flow Restriction training after ACL Reconstruction Surgery. The outcome measures will be assessed by hand held dynamometer.1-RM test, Illinois Agility Test, and Vertical jump test.

The data will be analyzed by SPSS,version 25.Statistical siginificance is P= 0.05.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: High Intensity Traditional Resistance Training Group
Group A will undergo Traditional Resistance training without blood flow Restriction. A 30-minute progressive, weight training program will be initiated 8 weeks after the ACL-reconstruction and will be conducted subsequent to the individual based program. The resistance (training loads) will be increased when the individual could do more repetitions than the number specified in the weight training protocol. The exercises will be performed at a slow speed to ensure full control of the movement.

Experimental: High Intensity Traditional Resistance Training with Blood Flow Restriction Group
Group B will perform low-load blood flow restriction (LL-BFR) training using external loads of 20-40% 1RM has been suggested as an alternative to traditional strength rehabilitation. Minimum of 2 -3 sets and maximum total 5 sets,20-30 repetitions of each exercise with 30 to 60 seconds rest period and 2-3 times per weekly for 4-6 weeks to During LL-BFR training, a pressurized cuff is applied to the proximal thigh that oc¬cludes venous outflow while maintaining arterial in¬flow. The combination of venous occlusion and resis¬tance training is believed to induce muscle hypertrophy secondary to elevated systematic hormone production, cell swelling, production of reactive oxygen species, intramus¬cular anabolic signaling and fast-twitch fiber recruit¬ment.(
