تاثیر پیش آماده سازی محدودیت جریان خون/ خون رسانی مجدد همراه مصرف مکمل بی کربنات سدیم بر تولید نیروی زیربیشینه پویا

Background and Aims: Sodium bicarbonate is a supplementation that used to reduce fatigue and increase power output in short-term training. On the other hand, the Ischemic Reperfusion Preconditioning (IRPC) is appropriate stimulus to increase the submaximal contractile response. The aim of this study was to investigate the effect of Ischemic Reperfusion Precondition in along with sodium bicarbonate supplementation on submaximal dynamic force generation. Materials and methods: 9 female student-athlete in double-blind randomized crossover design were three mode, sodium bicarbonate + IRPC, sodium bicarbonate and placebo+ IRPC. Participants move forward single arm dumbbell hand with a weight of 2 kg can be carried out most frequently. Every three training conditions records were collected. Plasma lactate concentration after the test was measured in all three conditions. In group IRPC, before testing the upper hand was under partial restriction of blood flow (BFR) for three minutes and after 1 minute reperfusion, motion carried. Data were analyzed using the Shapiro-Wilk test, analysis of variance with repeated measures and Bonferroni test at a significance level of P≤0.05. Results: The results showed that plasma lactate concentration and records of sodium bicarbonate + IRPC and sodium bicarbonate conditions were significantly difference compared to placebo + IRPC (Respectively p=0.001, p=0/02). Conclusion: According to the research findings, bicarbonate supplementation in IRPC training condition increased force and delay fatigue in submaximal dynamic contraction
