A basic study for establishing a suitable exercise prescription with long distance walking. II / 体力科学

ABSTRACT

The present study was performed to investigate the effects of 120 km walking, 40 km a day for 3 successive days on the condition that taking rest and foods freely, upon physical functions for healthy male and female subjects. All measurements were enforced at postabsorptive state early in the morning for the 10 successive days including the days of walking. Blood pressure, heart rate, and body weight were measured every morning. Blood samplings enforced, too. Urine collections were enforced from first day to 7 th day. The results obtained were as follows;<BR>1) There were no changes in heart rate, blood pressure, and body weight, which were measured early in the morning, before and after 120 km walking.<BR>2) Serum GOT and GPT activities had little changes, while serum LDH, α-HBDH, and CK activities increased gradually after walking.<BR>3) Serum CK-MB activities, which indicate myocardial injury, increased after walking, on the contrary CK-MB/CK ratio decreased. It was suggested that effects of 120km walking to myocardium were rather than slight ones.<BR>4) In spite of the same sorce in which serum CK-MB and LDH-1 were resulted, both did'nt exhibit same patterns in serum.<BR>5) Serum lipids decreased gradually after walking.<BR>6) Urinary excretion of creatinine and uric acid increased after 120km walking especially.<BR>7) If it is allowed to take sufficient foods and rest, 120km walking, 40km a day for 3 successive days, would not result in such a physical stress over the following days.
