Aim: Resistance training with new methods of exercise such as blood flow and respiration restriction that is more performed at a lower intensity is pursued various physiological responses. Therefore, the main purpose of this study was to determine the effect of blood flow and respiratory restriction on blood lactate concentration and growth hormone in the acute response to resistance exercise in collegiate wrestlers.
Method: In this study, a cross-sectional was used in which 8 collegiate wrestlers with more than two years' experience (mean age 26.87±4.7 years and body mass index 25.26±2.49 kg/m2) were randomy assigned in three conditions including: control (%801RM) and resistance exercise with blood flow and respiratory restriction (%301RM). Four sets with 15 repitations squat were considered as resistance exercise. Blood samples were collected before and immediately after exercise.
Results: all three types of exercise caused a significant increase in lactate and growth hormone immediately after the exercise (p <0.05), but no significant difference was observed between the groups (p <0.05).
Conclusion: The results of this study indicate that resistance exercise with restriction of blood flow and respiration such as routine resistance training can lead to increased metabolic and hormonal responses. This research also rather confirms­ the effectiveness of this type of exercise and satisfies the goals such as increased lactate and growth hormone expected from high intensity exercises.
