Comparison of Occlusive and Classical Hypertrophy Training in Terms of Thickness and Stiffness of The Muscle

Not Applicable

Completed

• Conditions: Hypertrophy; Muscle Tightness; Occlusion Vein
• Interventions: Other: Light hypertrophy training; Other: Heavy hypertrophy training

• Registration Number: NCT03149133
• Lead Sponsor: Istanbul University

Brief Summary

Occlusive or ischemic training is a type of strength training which is becoming more and more popular every day. The safety, efficacy and detailed description about the use of occlusive training is well documented in the literature. However, the effects on hypertrophy and the stiffness of the muscle tissue are not studied. We aimed to measure these changes by ultrasound technology in a randomized controlled design.

Detailed Description

Patients were randomized into classical hypertrophy and occlusive hypertrophy groups. The participants are free from any systemic disease, infection or recent injury. Both groups perform hypertrophy training with different intensities. The outcome measures are; thickness determined by B-mode ultrasound and stiffness by shear-wave elastography. Comparison of both groups will be made.
