To determine exercise regimen for management of diabetic patients, we determined the PCr/Pi ratio before and after streneous exercise on healthy volunteers and diabetic patients by using ³¹P-MRS (Magnetic Resonance Spectroscopy). In healthy volunteers, the decreased PCr/Pi ratio recovered rapidly after termination of exercise. In diabetics, the ratio recovered more slowly. The metabolic and hormonal changes after exercises (15 min hard-exercise, 30 min moderate-exercise, and 60 min light-exercise) were examined on diabetics. Glycemic reductions after exercises were similar among all three exercise regimens. Hard or moderate exercises evoked the rises of metabolites and hormones. Light exercise evoked no significant responses. These data indicated that diabetics showed the delayed recovery from exercise and exercise regimen for diabetics must be programmed not to evoke adverse effects of metabolites and hormones.
