Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The L-carnitine has demonstrated effects in the treatment of obesity mainly promoting the fat degradation during exercise.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

A randomized, double-blind, placebo-controlled clinical trial will be carry out in 24 woman with body mass index ≥ 25 to 29.9 kg/m2. The patients will receive 1.5 g of L-Carnitine deluded in 250 ml of water or placebo before crossfit training, 5 times a week for 8 weeks. Before and after intervention the investigators evaluate: The body composition (body fat, lean body mass), arm muscle circumference, waist circumference, body weight and body mass index.
