Resumo

This study was undertaken to characterize the effects of the linear periodized training in rats on aerobic and anaerobic performance, glycogen concentration in soleus, gastrocnemius and liver, hormones concentrations (testosterone and corticosterone), enzymes and metabolites (creatine kinase, lactate dehydrogenase, creatinine, uric acid and urea) as well as antioxidant system (catalase, superoxide dismutase and sulfhydryl groups) after basic, specific and taper periods. Seventy male Wistar rats were randomly separated in two groups: control/sedentary (CT, n = 40) and linear periodized training (LPT, n = 30). The LPT was carried out during a period of 12 weeks (w) with frequency of 6 days/week. The training period was subdivided in three mesocycles: basic (6 weeks), specific (4.5 weeks) and taper (1.5 weeks). The real volume of the training obtained in LPT reduced 7% in relation to the estimated volume. The anaerobic index in LPT after basic and taper was higher than CT in respective period but unchanged intra-group during mesocycles. The aerobic performance in LPT was higher than CT after basic, specific and taper. The creatine kinase and catalase reduced after the taper period in relation to CT and baseline. The glycogen stores in soleus increased after basic in relation to CT. The liver glycogen concentration increased after taper in relation to basic and specific period as well in comparison to CT. In conclusion, the stress biomarkers reduced in taper period in order to increase the aerobic and anaerobic performance in relation to CT. (AU)
