[Comparing the effect of Iranian NBC protective clothes [with and without mask] and usual combat clothes on aerobic capacity]

ABSTRACT

In many jobs such as military personnel especially in chemical attacks must active clothes to avoid physical, chemical and environmental damages. Such clothes should cause minimal physiological, mental and organic limitations on the body, beside their protective features. The of this study is to compare the Iranian NBC protective clothes with usual combat clothes, in terms of their on Aerobic capacity of the subjects. This is an experimental study. Thirty healthy male individuals according to criteria recruited for this study. After selecting type of clothes performed a physical activity according treadmill test while wearing NBC protective clothing with mask, NBC protective clothing without bind usual combat clothing. After physical activity such parameters as exhaustion time and distance measured. Aerobic capacity [Vo2max] was also predicted with Bruce equation. its data showed that Aerobic capacity [Vo2max] in NBC protective clothing with mask was 43.4 +/- 7.91mi/kg/min, in NBC protective clothing without mask 52.05 +/- 8.37 mI/kg/min and in usual combat was 59.57 +/- 6.54 mI/kg/mm. This difference was significant [p<0.001]. These three sets of clothes had different values in Parameters such as exhaustion time and distance. In the case of tolerance time and aerobic capacity [Vo2m.ax] the results obtained from the usual combat clothes showed greater values than NBC protective clothing with and without mask [P<0.05]. The results showed that Iranian NBC protective clothes with mask cause that the person has ass tolerance time, because the aerobic capacity [Vo2max] for these clothes was observed as less than NBC protective clothes without mask and usual combat clothes
