Abstract

Aerobic recovery after a 60-sec tetanus of skeletal muscle of frog was studied using the in vivo 31P-NMR method with a topical magnetic resonance spectrometer (TMR) at 17 degrees C. Creatine phosphate recovered with a time constant of about 25 min-1. Sugar phosphates increased by the Pasteur effect, and saturated at about 4.5 mmol/kg muscle. The high level of the sugar phosphates was sustained during the following 60 min.

摘要

使用局部磁共振波谱仪（TMR）在17℃下通过体内31P-NMR方法研究了青蛙骨骼肌60秒强直收缩后的有氧恢复情况。磷酸肌酸以约25分钟-1的时间常数恢复。糖磷酸盐因巴斯德效应而增加，并在约4.5 mmol/kg肌肉时达到饱和。在接下来的60分钟内，糖磷酸盐维持在高水平。
