| Introduction: By increasing the intensity of physical exercises the
energy consumption is also increased, which may cause possible alterations in
serum leptin levels, independent of fat cells. Hence, the aim of this study was
to investigate the effects of various intensities of aerobic-resistance
(concurrent) exercises on the levels of serum leptin,lactate, glucose and net
protein in active men. Materials and Methods: In a semi-experimental study plan, ten healthy young active
men, aged 21.5±1.4 years, BMI 21.88±1.2 kg/m2, performed concurrent (aerobic
and resistance exercise) exercise at the three levels of low, moderate and high
intensities. Different intensities of aerobic exercise included running on
treadmill at the speed of 8, 9.6 and 11.2 km/hr. The resistance exercises were
composed of 45, 65 and 85% of 1- repeated maximum intensity in six motions. The
data for aerobic and resistance exercises were all justified to a same level.
Blood samples were taken before and immediately and 24 hours after exercise. Results: The
results show that the plasma lactate concentration increased immediately after
exercise in compareto prior and 24 hours after exercise at all levels of
intensity (P0.05). Our findings also indicated that plasma glucose and total protein
levels of participants did not significantly change immediately and 24 hours
after exercise in compare to pre-exercise levels at different intensities of
physical activity. Conclusion: This study suggests that the different intensities of concurrent
exercise does not change effectively the leptin levels in young active men |
