conclusions acute l-carnitine supplementation possibly affects exercise performance and triglycerides in athletes rather than sedentary men. objectives this study aimed to investigate the acute effects of l-carnitine supplementation on aerobic metabolic efficiency and lipid profiles in sedentary and athletic men. methods fifteen sedentary (20.4 ± 1.5 years) and 15 athletic (21.5 ± 2.4 years) me...

the aim of this study was to determine the effect of 6 weeks of aerobic training and l-carnitine supplement on body fat percent and serum lipid profiles in active men. the method used was semi-experimental. eighteen active men were selected voluntarily and randomly divided into two groups of experimental (nine individuals with the average age: 44.4+8 years, weight: 8.2+16.6 kg, height: 173+6 cm...

the aim of this study was to investigate the effect of 8 weeks of selective exercise activity and estrogen supplement on satellite cells in ovariectomized sprague-dawley rats. at first, subjects were ovariectomized and after one month of complete recovery, they were randomly divided into four groups: control, exercise activity, estrogen supplement, and exercise and estrogen supplement. only exe...

Carnitine has important roles in skeletal muscle bioenergetics. Skeletal muscle carnitine deficiency is associated with profound impairment of muscle function. It has thus been natural to ask if carnitine supplementation can improve skeletal muscle function and athletic performance in healthy individuals. Oral carnitine doses of several grams cause no significant clinical toxicity, further enco...

Carnitine metabolism has been previously shown to change with exercise in normal subjects, and in patients with ischemic muscle diseases. To characterize carnitine metabolism further during exercise, six normal male subjects performed constant-load exercise on a bicycle ergometer on two separate occasions. Low-intensity exercise was performed for 60 min at a work load equal to 50% of the lactat...
