摘 要: 为了解运动对大绒鼠的生理学效应,在室内条件下,运用踏车测定强迫运动训练8周后大绒鼠体重、代谢率、能量摄入的变化。结果发现:强迫运动训练8周对大绒鼠的体重无显著影响;大绒鼠的代谢率和能量摄入均出现了显著增加,其中训练8周后静止代谢率较对照组增加了29.9%;运动最大代谢率较对照组增加了10.7%. 研究结果表明:在强迫运动训练期间,大绒鼠主要通过增加代谢率和食物摄入的方式维持自身的体重和能量平衡。经过长期的强迫运动,大绒鼠运动最大代谢率增加的幅度较低,这可能与其运动能力有限有关,也可能与其只分布在横断山区而没有向外扩散有关,其有关机制尚需进一步研究。
关 键 词: 生态学;大绒鼠;代谢率;能量摄入

Abstract: Maintaining a stable body weight requires a balance between energy intake and energy expenditure. Exercise which can increase energy expenditure, is one of the most important factor affecting energy balance for animals. In order to understand the physiological effects of exercise, changes of body mass, metabolic rate and energy intake were measured in Eothenomys miletus during 8-weeks of forced exercise training with treadmill. The results showed that exercise training had no significant effects on body mass, but the metabolic rate and energy intake were increased during 8-weeks exercise training, rest metabolic rate increased 29.9% and locomotor maximal metabolic rate increased 10.7%, respectively. All results indicated that increasing the metabolic rate and energy intake was the main way to regulate the body mass and energy balance in Eothenomys miletus during long-term forced exercise training. Moreover, the increase ratio of locomotor maximal metabolic rate was lower during long-term forced exercise training, it might be related to its ability of locomotion, and it was also related to its distribution only in Hengduan mountains region, not diffusing to other area. Its mechanism of lower ability of locomotion needs further study.
