Abstract

Abstract: Objective This study discusses the construction of a resistance training model for rats using a treadmill. Methods A total of 40 male SD rats aged 19 months were selected to determine the conditions for the establishment of a resistance training model. To this end, the angle and speed of the treadmill were measured, the changes of the rat tail load and lactic acid levels in their blood were tested. Results Rats underwent resistance training on the treadmill at an incline of 35°and a running speed of 15 m/min, the exercise regimen significantly improved. After exercising for 8-15 s, the average blood lactic acid concentration was 3.8-5.2 mmol/L. According to the energy metabolism and blood lactic acid half-time response, the resistance training of rats was performed as one training session for 15 s and 30 s intervals. After 4 training sessions in each group, the blood lactic acid concentration was relatively stable. The blood lactic acid concentration was 4-5 mmol/L after resistance training for 3 groups per day and 3 min intervals between groups. Conclusion A resistance training model in rats is established based on the incline, speed of the rat treadmill, and the tail load of rats.
