Abstract
Backgrounds: In order to remain competitive, athletes and coaches are constantly looking for ways to enhance performance. The aim of this study was to investigate the effect of HIFT training and hypoxia mask on maximum oxygen consumption and respiratory efficiency of the players of Iran's men's national ice hockey team.
Method: In this semi-experimental study, 14 players of the Iranian national ice hockey team were divided into two HIFT and HIFT exercise with hypoxia mask groups, then both HIFT groups and HIFT exercise with hypoxia mask, performed HIFT training sessions with 30 seconds repetition and five sets for about an hour, three sessions a week for six weeks. Before and after the training session, anthropometry, body composition, maximum oxygen consumption (VO2max) and respiratory efficiency (vE/VCO2) were measured using in-body device and gas analyzer. The data were analyzed using the analysis of covariance test at the P<0.05.
Results: The results showed that HIFT exercise and HIFT exercise with hypoxia mask have an increasing effect on VO2max in elite ice hockey men, but there was no difference between the effect of HIFT exercise and HIFT exercise with hypoxia mask on VO2max (P=0.390). After the training, vE/VCO2 decreased in both groups, but there was no difference between the effect of HIFT training and hypoxia mask on vE/VCO2 in elite ice hockey men (P<0.05).
Conclusion: According to the results, it seems that HIFT and HIFT exercise with hypoxia mask may be able to help improve the performance of respiratory system in elite ice hockey men.

Abstract
The aim of this study was to investigate the effect of 8-weeks of resistance training and vitamin D supplementation on some indicators of renal function in male rats with renal failure. Methods: In this experimental study, 16 male rats (7-8 weeks and mean weight: 350 to 370 gr) were divided into four groups (n = 4): training, supplement, training and supplement and control group. After induction of kidney damage through NX 5.6 surgical method and two weeks later, resistance training was performed for 8 weeks. Simultaneously, 1000 unit of vitamin D per week intramuscularly was injected. Finally, glomerular purification (using urea and creatinine levels) and serum levels of vitamin D, calcium and phosphorus were measured. Descriptive statistics, one-way ANOVA test and Tukey post hoc test were used to analyze the data. The results showed that glomerular filtration and vitamin D in the training and supplementation groups showed a significant increase compared to the control and training groups (P<0.05). However, Urea and creatinine and serum calcium and phosphorus significantly was decreased (P<0.05). It seems that the simultaneous use of resistance training and vitamin D supplementation can affect glomerular filtration rate.
