- Abstract
This study determined the parameters for prescribing physical training volume in rats, thus establishing an experimental model for ultra-endurance exercise. Twelve Wistar rats underwent an adaptation period on a motorized treadmill, and were subjected to physical testing of maximum intensity and volume. They were randomized in 2 groups: the control group (cont, n=6) remained sedentary and the trained group (trai, n=6) were subjected to physical training at 60% of maximum intensity and 75% of maximum volume. Data from the initial test intensity (cont: 26.9 ± 1.4 min; trai: 26.2 ± 1.4 min) and volume test (cont: 41.0 ± 7.3 min; trai: 40.4 ± 9.4 min) were similar between groups. Therefore, the trained group was subjected to an exercise regimen with duration of 30 min at a speed of 1.2 km/h per session during the first 2 weeks of training. Following this initial period of training, the t rained group showed significant gains both in the intensity test (cont: 29.7 ± 2.6 min; trai: 51.0 ± 2.0 min) and the volume test (cont: 69.0 ± 14.1 min; trai: 323.0 ± 49.8 min). After 4 weeks of training, only the volume tests showed significant differences between the 2 groups (cont: 69.0 ± 14.1 min; trai: 673.3 ± 40.9 min). These findings help to establish a model of physical training to develop ultra-endurance in rats based on volume adjustment.
