Abstract
Healthy mice were submitted or not to daily chronic swimming and/or daily yerba mate (YM) infusion intake and had their bloods analyzed after four weeks. We hypothesized that daily intake of YM may act differently on lipid mobilization and, on the creatine, lactate and irisin levels in sedentary mice and those submitted to chronic exercise. The groups were (n=48): YM-non-treated control (NTC), YM-non-treated swimming control (NSC), non-roasted YM (NRY), roasted YM (RY), swimming plus non-roasted YM (SNRY), swimming plus roasted YM (SRY). No significant (P>0.05) difference was observed concerning creatine phosphoskinase (CPK) value. Lactate level decreased significantly (P<0.05) for SNRY and SRY, suggesting accelerated lipid mobilization and glycogen sparing potential. There was significant (P<0.05) body weight loss in all, except for NTC. Higher weight loss in NRY, RY, SNR and SRY indicated greater lipid mobilization. Thiobarbituric acid reactive substances (TBARS) and irisin had significantly (P<0.05) higher values for RY. This is first report that deals with the effect of YM consumption on serum irisin level. Major amounts of caffeic acid derivatives, slightly increased caffeine and less amount of rutin may be responsible by accelerated lipoperoxidation in sedentary healthy mices chronically treated with roasted YM. Chronically consumed YM plus swimming aid in healthy weight loss. Sedentary lifestyle plus roasted YM chronic consumption may cause accelerated lipid mobilization and increased TBARS production via irisin overexpression leading to an increase in lipoperoxidation.

The yerba mate (YM), a native South American plant, is consumed as a hot or cold beverage which is appreciated around the world
Our group hypothesized that the daily intake of YM may exert a different action in the lipid mobilization and, irisin, lactate and creatine levels in sedentary group compared to that submitted to chronic swimming
There was a synergistic effect between aerobic chronic exercise and YM consumption, which resulted in significantly (p
Summary
The YM, a native South American plant, is consumed as a hot or cold beverage which is appreciated around the world. Reference [9] investigated the effects of YM consumption on muscle damage and strength recovery after acute eccentric bout. Both variables were favourably modulated in the treated group when compared to control. Our group hypothesized that the daily intake of YM may exert a different action in the lipid mobilization and, irisin, lactate and creatine levels in sedentary group compared to that submitted to chronic swimming. Our group have investigated the effect of YM on blood total CPK, lactate, body weight, TBARS value and irisin in sedentary and aerobically exercise-trained healthy mice
