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

Overview

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.

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: Randomized
    • Intervention Model: Parallel Assignment
    • Primary Purpose: Screening
    • Masking: Double (Investigator, Outcomes Assessor)
  • Study Primary Completion Date: August 15, 2017

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.

Interventions

  • Other: Heavy hypertrophy training
    • Training with 75-80 % of 1-RM
  • Other: Light hypertrophy training
    • Training with 35-50 % of 1-RM

Arms, Groups and Cohorts

  • Experimental: Classical Hypertrophy
    • The classical hypertrophy group performs strength training with 75-80% of 1-Repetition Maximum.
  • Experimental: Occlusive Training
    • The occlusive hypertrophy group performs strength training with -50 of 1-Repetition Maximum.

Clinical Trial Outcome Measures

Primary Measures

  • Thickness
    • Time Frame: 6 weeks
    • The thickness of the biceps brachii muscle determined by B-mode ultrasound
  • Stiffness
    • Time Frame: 6 weeks
    • The stiffness of the biceps brachii muscle determined by ultrasound elastography

Secondary Measures

  • Strength change
    • Time Frame: 6 weeks
    • Arm flexion strength determined by isokinetic dynammometer
