Abstract

Background and Aim: Considering to the new conditions compared to the traditional concept, military training courses should be designed in such a way that becomes efficient, effective, and works properly and practical. In contrast, their physical training develops from other types of aspects such as metabolic and hormonal. Resistance exercise (RE) with different types of military and training equipments, such as gas masks, and training masks that performs with a low intensity, results in different physiological responses and effects. Therefore, the main goal of this research was to study the effect of two types of military and training masks during resistance sports exercise on lactate and growth hormone responses in the AJA simulated training program.
Methods: In this study, the case-crossover method was used. Twelve military personnel trained (with an average age of 27.75 ± 6.45 years and a body mass index of 25.41 ± 3.43 kg/m2) were randomly chosen and examined in three different physiological training methods: traditional (control) training (Intensity: 1RM 75%), training with military and training masks (1RM 30%). The RE consisted of performing 4 squat movements with a total of 65 repetitions. Blood samples were collected before and immediately after the workout. The data were analyzed using the two-way analysis of variance method with repeated measurements, with SPSS software (version 23) at a significance level of P<0.05.
Results: All three types of exercise caused a significant increase in lactate (P<0.05) and no increase in growth hormone except the traditional method immediately after the exercise, but there was a significant difference between the groups in the amount of lactate, but not in the amount of growth hormone (P<0.05).
Conclusion: Studies have shown that both methods of resistance sports activity with a military mask and exercise such as routine resistance activity can cause a significant increase in blood lactate after exercise. This research confirms the effectiveness of this type of training on lactate increase response and can meet the goals expected from high-intensity training.
