Carnitine Supplementation and Skeletal Muscle Mass

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.

Primary outcomes

  1. Muscle Strength using Biodex System 4 Pro dynamometer

    Time frame: 24 weeks

    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.

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

    Time frame: 24 weeks

    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.

Secondary outcomes

  1. Plasma trimethylamine N-oxide concentration

    Time frame: 24 weeks

    Blood samples taken before the start and after finishing the supplementation protocol. Plasma trimethylamine N-oxide determined using ultra performance liquid chromatography - tandem mass spectrometer (UPLC-MS/MS) method
