Adaptation to Exercise in Middle-Aged and Old Runners
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.3 Vol.3】
Effects of 7km running on heart rate, electro-cardiogram (ECG), plasma noradrenaline, serum CK isoenzyme and LD isoenzyme in 3 middle-aged and old healthy men (46-48 years old: range) having exercise habits (3-7 years: range) were investigated.
The results were as follows:
1) No changes were observed in ECG before and after exercise.
2) Heart rate were elevated up to 123 beats/min (mean value) immediately after exercise.
3) Plasma noradrenaline concentration showed increase of 1.82 ng/m (mean value) immediately after exercise.
4) Mean value of serum CK-MB activity was 12.6, 14.7 and 11.1 Iu/L (rest, immediately after exercise and next day, respectively).
5) Plasma noradrenaline, LD₄, LD₅ and CK activity in next day remained elevated for rest level.
