The effect of short-term β-hydroxy-β-methylbutyrate supplementation on changes of LDH and CRP induced by one intensive resistance exercise in untrained male students.

The purpose of this study was to determine the effect of short-term β-hydroxy-β-methylbutyrate supplementation on changes of LDH and CRP induced by one intensive resistance exercise in untrained male students. Fifteen، healthy and untrained young male students (age: 23. 4±2. 06 years، height: 173. 96±6. 77 centimeters، weight: 70. 07±12. 17 kilograms، BMI 23. 05±2. 96 kg/m2 and fat: %17. 49±5. 62) were selected and divided to two groups randomly: HMB (n = 8) or placebo (n = 7). Subjects use HMB or placebo 6 days before a bout intensity weight training with %70 - 75 of 1RM. LDH and CRP were Assessed before، 1 and 24 hours after exercise. The results show that HMB consumption before an intense resistance exercise have significant influence on the serum LDH levels (p= 0. 038)، but dont have significant influence on the serum CRP levels (p=0. 129).
