چکیده مقاله:
This study aimed to determine the delayed effect of one session of concurrent exercise on serum leptin and resistance insulin levels of
sedentary men. Materials and Methods: Fifteen healthy young men with a mean age of ۲۲.۹ ± ۱.۷ years and a body mass index of ۲۳.۳ ± ۱ kg/m۲
voluntarily participated in this experimental research. They participated in one session of concurrent exercise including ۲۰ min of aerobic
running on a treadmill at ۶۰%–۷۰% maximum oxygen uptake plus a resistance exercise at the intensity of ۷۰% of ۱‑repetition maximum with
ten repetitions per set to second round. Blood serum leptin, glucose, insulin, and insulin resistance index were assessed before, ۲۴, ۴۸, and
۷۲ h after the exercise program. Results: The results showed that leptin level did not change statistically significantly immediately and ۷۲ h
after the exercise termination (P > ۰.۰۵) but did decrease statistically significantly ۲۴ and ۴۸ h after the exercise program (P ≤ ۰.۰۵). The
result also showed that insulin and insulin resistance levels decreased statistically significantly immediately after the exercise and lasted for up
to ۴۸ h postexercise (P ≤ ۰.۰۵); however, it returned to its initial value after ۷۲ h of recovery (P > ۰.۰۵). Conclusions: It was concluded that
energy use in one session of concurrent exercise might reduce leptin levels up to ۴۸ h of recovery. In addition, a decrease in insulin, a known
inducer of leptin expression in adipocytes, occurs before the decrease in leptin. This change may mediate the decrease of leptin concentration.
