Objective To observe the influence of different load on the rat gastrocnemius muscle spindle of shape and structure. Methods Adopt swimming training model. Medium load group swim 60 min each day. Over load group, loaded with the weight of 5 %, swim 60 min each day, 6 days a week. Adopt muscle spindle of Faworky’s display and electron microscopy techniques; observe changes of different load training on the rat gastrocnemius muscle spindle shape and structure. Results show that gastrocnemius muscle spindle form is smaller, while muscle spindle structure is normal. In medium load group muscle spindle structure is integrate, spindle extrinsic is aligned, muscle spindle in neural myelin structure are clear and complete, nuclear bag fiber, nuclear chain fiber diameter than the control group significantly increases. In over load group spindle body increased obviously, inside and outside is separated by capsule seriously. Muscle fibrils quantity is less, sac cells are swollen, axis clearance increased obviously, spindle in neural axis lining and myelin has separated. These preliminary findings indicate medium load movement could significantly improve muscle spindle shape and structure, while over load sports training could lead to pathological changes of muscle spindle structure.
