The aim of this study was to investigate quantitatively the power ability of middle and older aged men in the vertical jump.
And, we would try to point out the changes with increasing ages and the influences of the environments factor to the power ability.
Based on the environment point of view, we put an emphasis and consideration on those who did physical exercises and also those who drove a car in a daily life.
Subjects were the health 201 men who visited the sports sauna training center of national stadium for physical exercises.
The power was calcurated from the force and velocity concerning of jumper's C.G. during the take off motion. The force was measured by using a strain gage type tranceducer, and the velocity was calcurated by integrating the equation of motion about of C.G.
Result:
The power ability of middle and older aged men in the vertical jump decreased with increasing ages.
The rate of decrease with every 5 years of age was 0.248 horse power, 2.960×10^-3 horse power in the maximum power and maximum power per body weight.
In comparison with the power ability of 25 years old, the power ability, in terms of maximum power per body weight, of 35 years old, 45 years old, 55 years old were 90.8%, 81.1%, 59.0%, respectively.
There were evidently differences between trained men and untrained men, and then car driver and no car driver in the power ability. The differences of maximum power per body weight were 12.190 × 10^-3 horse power, 9.231×10^-3 horse power, respectively.

Recently, the popular usage of the sauna bath has been greatly increased but this is not necessaeily based upon scientific ground.
This investigation has been made on the most ideal usage time with special emphasis on duration of time in the actual sauna room.
The usage pattern, in view of the times of taking the sauna room and the cold water, has been established.
And then the influences on the body function were measured.
The usage pattern were as follows (Repetition were all 3 times)
(1) 5 minutes stay in the sauna and 1 minute in the water
(2) 7 minutes stay in the sauna and 1 minute in the water
(3) 7 minutes stay in the sauna and 2 minutes in the water
(4) 10 minutes stay in the sauna and 2, 5 minutes in the watar
The result were as follows
1. The usage pattern (1) gave the good result for the function of whole body reaction time, patellar-tendon reflex time, maximum power of vertical jump.
Another usage pattern (2), (3), (4) gave the wrong result for those function.
2. There were no remarkable differences blood pressure, heart rate and skin temperature among the usage pattern (1), (2), (3), (4) .
3. Oxygen intake in the usage pattern (2) gave a large value than the usage pattern (1) .
In the view of the energy expenditure, it was recognized that the usage pattern (2) was the best usage.

We implemented a questionnaire survey targeting mothers who are in child care and had participated in consultations regarding drugs and diseases. We examined the future roles of community pharmacists by exploring the mothers’ concerns and, anxieties about child cares and their backgrounds, and their expectations for profession of community pharmacist. Mothers have listed anxiety and concerns of child care about “dermatitis such as rash and atopic eczema”; “food allergies”; “infectious diseases such as measles, chicken pox, and mumps”; and “side effects of vaccination”. In addition, most of them indicated their own concerns and anxiety about “solutions to children’s illnesses.” Despite their anxieties and concerns, however, approximately 60% of the mothers have never consulted with community pharmacists. Among them, approximately a half of them indicated the following three reasons why they have never consulted with pharmacists: “I have nothing to talk about,”, “I do not know what I should talk about,”, and “I was not sure if it was alright to talk about my concerns.”. From these results, we concluded that community pharmacists in the future should improve their communication skills and inform their availability to consult about medicine and disease to local residents.

Vibration sensation is related to motor function. However, it is unclear which vibration frequencies are associated with motor function. Therefore, in this cross-sectional study, we investigated whether a specific frequency of vibration sensation could explain motor functions. Thirty-two community-dwelling Japanese healthy older adults aged 70 years or older participated in the present study. Grip strength, one-leg standing time, and 10-m walking time were evaluated as indicators of motor function. Vibratory (40, 128, and 256 Hz) and tactile sensory tests were examined as sensory functions. Grip strength per body weight was significantly correlated with sex, body mass index, falls efficacy scale, vibration sensation with 40 and 128 Hz, and 10-m walking time (P < 0.05). Furthermore, one-leg standing time showed a correlation between vibration sensation (128 and 256 Hz) and fall history (P < 0.05). However, 10-m walking time was significantly correlated with only the grip strength to body weight ratio. Multiple regression analysis showed that vibration sensation with 128 Hz (β = 0.427) and sex (β = -0.335) (P < 0.05) were significant independent variables associated with grip strength to body weight ratio. Vibration sensation with 256 Hz (β = 0.465) and age (β = -0.343) (P < 0.05) were significant independent variable associated with one-leg standing time. No significant variables were identified for the 10-m walking time. Vibration sensation associated with motor function shows specific frequency characteristics in community-dwelling older Japanese adults.
