Role of muscle spindle in weightlessness-induced amyotrophia and muscle pain

Using method of questionnaire,investigating condition and analyzing the cause on the muscle soreness in physical education teaching of schoolgirls in college,and putting forward the methods of preventive and terms of settlement.

By questionnaire,the author investigated the condition and analyzed the cause for the muscle soreness of schoolgirls at the vocational schools in physical education ,and put forward the methods of prevention and solation,which has an active meaning in improving the interest and effect on physical education among schoolgirls at the vocational schools.

acupuncture Acupuncture and magnetic treatment to allveiate muscle ache were adopted respectively,in contrast with the controll group,the manifestation degree of muscle ache,electromusclegram amplitude and disappearing time of muscle ache in every period were observed.

Long time exercises will extend the feeling of muscle ache because of injury and spasm of the muscle fiber.

The Positive Function of DOMS on Human Body from the Perception of Super-compensation Theory

Mechanic injury,spasm,inflammation and inchoate reperfusion injury are of great importance in mechanism for the DOMS.

The unaccustomed eccentric activities may lead to DOMS.

By comparing the researches in skeletal muscle ischemic reperfusion inj ury and delayed onset muscle soreness,according to their characteristics in occu ring time,the changes in microstructure,the main biochemical indexes,we put forw ard a hypothesis: skeletal muscle ischemic reperfusion injury is the mechanism o f delayed onset muscle soreness.

There might be three phases of delayed onset muscle soreness (DOMS)recovery, endogenous glucocorticoids might premote proteolysis of damaged proteinsin the second phase, but inhibit protein synthesis in the third phase.
