Abstract

Aim: The purpose of this study was to investigate the effect of strength training and c4 supplementation on strength, arterial oxygen saturation and lactate accumulation in strength training men. Methods: For this purpose, 45 men (age: 22 to 35 years) who had at least one year of regular resistance training history were randomly selected and divided into 3 groups of 15 controls, Strength training + placebo and strength training + supplement c4. Subjects performed the same resistance exercises for 6 weeks. Subjects in the supplement group consumed 5 grams of c4 supplement daily in 6 meals for 6 weeks and the placebo group consumed the same amount of starch 30 minutes before exercise. Pre and post intervention arterial oxygen saturation and lactate levels were measured. Results: strength training in both groups did not lead to significant blood lactate accumulation or oxygen saturation (P>0.05) in spite of significantly increased upper and lower muscle group strength values(p < 0.05). Moreover, no between group difference was recorded for amount of strength development throughout the intervention period (P>0.05). Conclusion: c4 supplementation nor has benefits on strength performance, neither lowers blood lactate in strength trained athletes.
