Efeitos dos treinamentos aeróbio, anaeróbio e concorrente na composição corporal e capacidade aeróbia de ratos wistar

Resumo (EN)

Objective – To analyze the effects of aerobic, anaerobic and concurrent on the body composition and aerobic capacity of Wistar rats. Methods – Twenty-two Wistar rats, 100 days of age, were assigned to the following groups: control (CTLE, n= 05), anaerobic training (TAN, n= 06), aerobic training (TAE, n = 06), and concurrent training (TCC, n = 05). The following variables were measured: body mass index (BMI) and Lee Index (iLee); epididymal adipose tissue (TecAdp), and feed efficiency coefficient. Results – The body mass demonstrated an increase in CTLE (pre 450.96 ± 17.63, post 463.08 ± 17.7547), TAE (pre 369.05 ± 18.22, post 388.13 ± 18.74), and TCC groups (pre 408.60 ± 6.39, post 430.72 ± 9.30) between the pre and post-training periods. The iLee presented a significant difference between the TAN (3.08 ± 0.44), TAE (2.93 ± 0.04) and TCC groups (2.91 ± 0.23), and the BMI showed a significant difference between the TAE (0.63 ± 0.03) and TAN groups (0.73 ± 0.02). For TecAdp, a significant reduction was observed in the TAE group (6.91 ± 0.43) compared to the CTLE (13.87 ± 1.46). Conclusion – That aerobic training was more effective than TAN and TCC for reducing BMI and iLee, in addition to the TAE group presenting a lower mass of epididymal adipose tissue than the CTLE animals.
