The effect of 8-weeks circuit judo training on the AGRP amount and functional characteristics of trained judo males

  Judo is one of the weight categorized combat sports which keeping the ideal weight or reducing it, is vital for athletes. Many obstacles involved in energy hemostasis and storage which seems that AGRP or agouti related protein is one of them. AGRP is appetite-related neuropeptide which affects food consumption, obesity and energy hemostasis. Thus, the aim of this study was to compare the effect of 8 weeks judo-based circuit training versus common judo training on AGRP amounts. for this purpose 20 trained judo athletes voluntarily participated in this study and randomly placed in 2 groups (judo technique based circuit training, common judo training). Blood sampling was performed 24 hours before 1st and after the last training session. Comparing of AGRP changes among groups had performed using t-student and the levels of significance differences defined as (p<0.05). AGRP increase and body fat percent loss were significantly higher in circuit training compare with common judo training. In addition this group experienced more increase in VO2max, max power, mean power and fatigue index. The observed decrease in the AGRP can be related to the negative energy balance occurred in training that secretion of AGRP would be as a compensating way for restoring the energy
stores. Thus this method of training could be used as a better conditioning program for weight loss and achieving higher level of physical fitness for judo athletes.
