Abstract :
This study aimed evaluate the effect of short-term detraining following 6 weeks of high-intensity interval training on HIF-1α, bronchus, and bronchioles apoptosis levels on lung tissue in male Wistar rats. For this purpose, 18 healthy Wistar male rats (4 weeks with a mean weight of 72±9.9 g) were divided into experimental (n=12) and control (n=6) groups. After 6 weeks of high-intensity interval training, 6 rats the experimental group was transferred to the detraining group (n=6) and kept in detrain condition for three weeks. To measure of HIF-1α and bronchus and bronchioles apoptosis, a lung tissue sample was taken and measured at the end of the ninth week. One-way analysis of variance at the significance level (P≤0.05) was used to analyze the data. The results showed that despite the significant increase in HIF-1α and bronchial apoptosis and pulmonary bronchioles (P≤0.05) during high-intensity training, there was a significant decrease (P ≤ 0.05) in HIF-1α, bronchial apoptosis and bronchioles of lung tissue were observed. It seems to be done by the increase of the amount of HIF-1α and apoptosis in multiple cell lung bronchi and bronchioles, but the detraining period will decrease..
