    The purpose of the present study was to clarify the physiological characteristics of grass skiing from the viewpoint of aerobic and anaerobic metabolism. In slalom (SL), O_2 requirement was 3.488l and the energy sources were derived 11.7% from aerobic, 69.8% from alactic and 18.5% from lactic metabolism. On the other hand, in giant slalom (GSL), O_2 requirement was 4.086l and the energy sources were derived 31.7% from aerobic, 52.8% from alactic and 15.5% from lactic metabolism. In 20s maximal bicycle ergometer pedaling, O_2 requirement was 4.443l and the energy sources were derived 8.8% from aerobic, 55.7% from alactic and 35.5% from lactic metabolism. On the other hand, in 50s pedaling O_2 requirement was 5.848l and the energy were derived 29.4% from aerobic, 38.2% from alactic and 32.4% from lactic metabolism. O_2 requirement in SL and GSL was corresponded to about 70% and 80% of O_2 requirement in each bicycle ergometer pedaling. And they were represented by low blood lactate concentration. From these results it was concluded that in grass skiing the energy supply derived from lactic metabolism would be little and the contribution rate of alactic metabolism would be high.

    The purpose of this study was to explore effects of physical fitness, sports activities and aging on low-back pain (LBP). The subjects (age: 20-62 years) were two hundred six women who worked at a nursing home. They performed a physical fitness test which consisted of anthropometry (height and weight), muscle strength (grip, trunk extension, trunk flexion and knee extension), trunk flexibility (flexion and extension), balance (one leg standing with eyes open and eyes closed), and 1Om-walking at maximum speed(velocity, step length, and cadence). All variables in the physical fitness test except weight decreased with aging. A factor analysis with a Varimax rotation revealed four interpretable factors; STRENGTH, WALKING, FLEXIBILITY and BALANCE. The subjects answered a questionnaire on experience of LBP, sports activity, and an exercise for preventing LBP. The past and/or present experience of LBP increased with aging; 64.9% in 20-39, 71.2% in 40-49 and 75.9% in 50-59 age group. A path analysis was applied to a model, whereby four physical fitness factor scores, age, sports activities and the exercise for preventing LBP (EXERCISE) were assumed to effect on the LBP experience. The path analysis indicated that STRENGTH, FLEXIBILITY and EXERCISE had direct effects on LBP, while aging, sports activities, and EXERCISE related to the LBP experience indirectly through STRENGTH and FLEXIBILITY. This study supported the hypothesis that the experience of LBP was affected by muscle weakness and a limit in trunk flexibility which were dependent on aging and sports activities. The contribution of these factors to the LBP was small(7%), suggesting many other causes of LBP.

    A technique is presented for determining the angular momentum of the human body about its mass centre for general three-dimensional movements. The three orthogonal components of the angular momentum X, Y, and Z of 15 body segments composed of a transfer term and a local term were computed. The total angular momentum of the whole body was considered to be composed of the sum of the angular momentum of each body segment. The three-dimensional coordinates for determining the angular momentum were computed by a Direct Linear Transformation Method from film data. For calculated individual angular momentum the relative error is estimated to be within 7.2%. The application of the principle of conservation of angular momentum was discussed for the jumping smash of badminton. A large angular momentum was generated by rotation of the smash arm during the airborne phases. The lower limbs react upon the arm with an equal and opposite angular momentum to keep the angular momentum constant. This kind of counter rotation to the smash arm was useful to keep the body balance and reinforce the hitting arm.

    The purpose of this study was to investigate overhand throwing motions of adult women using path analysis. Throwing motions of 164 adult women were videotaped simultaniously from side and overhead views by two video cameras. Variables such as initial velocity of ball, velocity gained by body segments, body angle, angular velocity and evaluation of motions were obtained from video analysis. The path model indicating the cause and effect relations among these factors was investigated by path analysis. The main results were as follows: 1) Influences of velocities gained by body segments on initial velocity of ball were bigger in order of arm, trunk and legs. 2) Forward rotation of shoulder and raising of upper-body during main phase and whip-like action influenced on velocities gained by body segments directly and indirectly. 3) Style of motion of arm and legs during Postures at the starting of main phase.
