NCT05009641

Brief Summary

The primary aim of the current research project is to investigate the effect of carnitine supplementation on muscle strength and body composition. A secondary aim of this project is to explore the effect of circulating trimethylamine N-oxide elevation, induced by carnitine supplementation on muscle strength and body composition.

Outcome Measures

Primary Outcomes (2)

  • Muscle Strength using Biodex System 4 Pro dynamometer

    Peak torque measured by performing maximum voluntary contractions during isometric knee extension and flexion. The test performed in concentric-concentric mode consisting maximum 4-s knee extensor isometric contraction and maximum 4-s knee flexor isometric contraction, separated by 20-s recovery, repeated three times. Muscle isokinetic strength assessed in 5 repetitions of flexion and extension at a speed of 60°/s. Muscle endurance assessed in 10 repetitions at 300°/s determine the ability of the muscle to maintain the work. Strength testing performed on the Biodex System 4 Pro dynamometer.

    24 weeks

  • Body Composition: Body Fat Mass, Fat Free Mass, and Skeletal Muscle Mass using a bioelectrical impedance analyzer (InBody720)

    The InBody720 measures impedance of five segments of the body (each arm, each leg, trunk) at frequencies of 1, 5, 50, 250, 500, and 1000 kHz through the 8-polar tactile-electrode. Based on the impedance, body fat mass, fat free mass, and skeletal muscle mass are calculated.
