Product Description （Small Animal Metabolism Treadmill）

The small animal treadmill is mainly used for training and metabolic research in mice, rats, and other animals. It can make training quantification more accurate, and it is also necessary experimental equipment for animal physical fitness/endurance/sports injury/running nutritional drugs/sports physiology and pathology research.

The device is controlled by a seven-inch touchscreen, which can turn the power on or off, adjust the magnitude of the electrical stimulation, shield the corresponding channel, and preset the number or time of electric shocks to determine when the small animal is exhausted. The treadmill tilt angle is adjustable from 0 to 30 °.

Brief Explanation of the Operation of the Small Animal Treadmill

1. Firstly, the purchased rats and mice are placed in the laboratory for adaptive feeding for about a week

2. Then perform adaptive exercise training on the treadmill in the second week

Usually, the treadmill runs slowly, with a set speed of 15-20 meters per minute. (To achieve better training results, different speeds can be set in segments. For example, the first three-minute speed is set to 5 meters/minute, the second three-minute speed is set to 10 meters/minute, the third three-minute speed is set to 15 meters/minute, and the last one-minute speed is set to 20 meters/minute. This progressive training method can help animals adapt faster to the treadmill training rhythm. ) After putting the mouse into the chamber for one minute, electrical stimulation is applied, and the stimulation current is adjusted to around 0.8 mA. After receiving electrical stimulation, the mouse will immediately jump onto the moving treadmill and move in the opposite direction of the treadmill. If the mouse that jumps onto the table does not run, it will be brought into the electrical stimulation area by the conveyor belt and hit again by the electrical stimulation, and it will jump onto the conveyor belt to run again. Running training should be conducted once a day, for ten minutes each time. This training should be conducted approximately 5-6 times (individual mice that consistently refuse to run should be excluded during formal experiments).

3. During the formal experiment, researchers set the movement speed, slope angle of the running platform, etc., according to the research project's needs to conduct animal sports running platform experiments.

4. Explanation of Comprehensive Application of Sound Light Stimulation and Electric Stimulation

Electrical stimulation is a physical contact stimulation that generally affects the physiological indicators of animals. Sound and light stimulation belongs to non-contact stimulation and generally has no effect on physiological indicators. If both sound and light stimulation are applied simultaneously. Behavioral studies have shown that after multiple pieces of training, the mice gradually memorize the connection between electrical stimulation and acoustic-optic stimulation. That is, when mice hear sound and see light simultaneously, they will recognize the presence of voltage based on their memory and immediately jump onto the conveyor belt to run. The purpose of doing this is to reduce the impact of electrical stimulation on the physiological indicators of exercise mice, even when there is no voltage and only sound and light stimulation.

The gas-stimulated animal treadmill overcomes the interference of traditional electrical stimulation on animals' physiological indicators with milder stimulation and no damage to animals. At the same time, it can achieve the goal of driving animals onto the running belt.
