JOURNAL FREE ACCESSThe 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;
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.
2) Serum GOT and GPT activities had little changes, while serum LDH, α-HBDH, and CK activities increased gradually after walking.
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.
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.
5) Serum lipids decreased gradually after walking.
6) Urinary excretion of creatinine and uric acid increased after 120km walking especially.
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.View full abstractDownload PDF (1199K) -

JOURNAL FREE ACCESSThe variation of lengths, cross-sectional areas, weights, tetanic tensions, and passive tensions in extensor digitorum longus muscles in mice were investigated during postnatal growth. The increase of tetanic tension was discussed in relation to morphological changes of muscle. The muscle lengths were measured at right angle of articulatio genus and talocruralis (L0) . Following results were obtained: 1) The length, cross-sectional area and weight of muscle increased rapidly up to 7 th weeks, and tetanic tension developed significantly in 2 nd to 5 th week. 2) The muscle length (ML), muscle cross-sectional area (MCA) and muscle weight (MW) correlated significantly with the measured tetanic tension (TT) at L0 (the correlation coefficient r=0.852, 0.886 and 0.903 in ML, MCA and MW respectively) . 3) TT/MCA and TT/MW decreased in 7 th to 8 th week. 4) The passive tension at 130% L0per MCA showed maximum values in 8 th and 9 th weeks. 5) Relative muscle endurance were reduced in 2 nd to 4 th week and reached to steady level after 4 th week. These observations suggest that the functional development of muscle is late for morphological one and/or rapid morphological increment affects the contractile properties of muscle.View full abstractDownload PDF (745K) -

JOURNAL FREE ACCESSFive long-distance runners and five non-athletes were examined on lipoprotein metabolism at rest, during, and after pedaling exercise (60% of the maximal oxygen uptake) . At rest, the concentrations of the cholesterol (Cho.), triglyceride (TG), and phospholipid (PL) of very low density lipoprotein (VLDL) were kept at low level in the longdistance group compared with the non-athletes. The difference is significant (p<0.01) . On the other hand, the levels of the Cho, and PL of high density lipoprotein (HDL) were maintained high (p<0.05) . The concentrations of the TG of VLDL are in negative correlation with those of the Cho. (p<0.01) and PL (p<0.001) of HDL at rest. A positive correlation between Cho. and PL of HDL was also noted (p<0.001) . The TG of the VLDL decreased gradually with pedaling exercise in the long-distance group, reaching about 12 percent below the resting value just after exercise. However, no apparent change was noted in the non-athletes.
The results obtained indicate that the long-distance runners, compared with nonathletes, tends to use lipids in order to produce energy for exercise. There is little possibility of transferring from the Cho. and PL of VLDL to the lipoprotein during exercise for the results of no change in concentrations of the Cho. and PL of low density lipoprotein (LDL) and HDL. We concluded that the Cho, and PL of VLDL could gradually transfer to HDL by a heap of the endurance exercise for long period.View full abstractDownload PDF (902K) -
