Comparable effects of two types of interval and traditional resistance exercise on lipolysis and glycolysis in healthy young men

Exercise is one of the lifestyle interventions that is recommended for weight loss and improving health. The Purpose of present study was to compare the effects of two types of resistance exercise with active and passive recovery on lipolysis and glycolysis in healthy young people.Twelve healthy males (Mean±SD; age, ۲۵.۵±۳.۱ years; Body mass index, ۲۴.۲۱±۲ kg/m۲) after familiarization and determination of maximum strength ۱RM performed the first session. in this session subjects after warm up performed traditional resistance exercise (TRE) at ۸۰% of ۱RM included ۳ sets of ۶ repetitions with ۲ min passive recovery, and In the second session an interval resistance exercise (IRE) trial at ۶۰% ۱RM (include ۳ sets of ۶ repetitions) followed by active recovery (۱ set of ۶ repetitions at ۲۰% of ۱ RM). Three blood samples were taken before and immediately after exercise, and after one hour recovery and were analyzed to measure glucose, insulin, non-esterified free fatty acid (NEFA) and glycerol concentration.Statistical analyses revealed a significant effect of IRE on insulin concentration. Plasma insulin significantly decreased during recovery after IRE session (P=۰.۰۰۲). Plasma glucose concentration significantly increased during recovery after IRE (P<۰.۰۵). No significant differences were observed between responses of NEFA and glycerol to two resistance exercise trails but the concentration of NEFA increased significantly during the recovery period, (P<.۰۵).We conclude, that IRE leads to more reductions in insulin concentrations during exercise and subsequent recovery and as a results more lipolysis during recovery period than TRE protocol.
