Excess body fat has generally been considered to influence physical fitness and motor ability in obese boys. However, very few studies have been done on the relationships of percent body fat (%fat), body fat and fat-free mass with physical fitness and motor ability. The purpose of this study was to clarify the relationships between body composition and selected physical fitness and motor ability elements in obese boys. The subjects were three hundreds and five boys aged 12-14 years. Eighteen physical fitness and motor ability elements were tested and skinfold thickness was measured at six sites using an Eiken-type caliper. Impedance (Z) was measured using a tetrapolar bioelectrical impedance plethysmograph (Selco SIF-891) . Body density was calculated from the formula of Kim et al. Variables which represented muscular power and endurance were negatively affected by %fat, while muscular strength was positively related to %fat. Flexibility variables were found not to be affected by %fat. In order to further examine the effects of %fat on physical fitness and motor ability, the subjects were categorized into three groups according to %fat: lean= less than 12% (n=64), average=12-20% (n=192), and obese=greater than 20% (n=49) . The results of comparison among groups clearly indicated that the obese group was significantly poorer in muscular power and endurance but was better in muscular strength than the other groups. To analyze the factorial structure in obese boys, principal factor analysis was applied to the correlation matrix which was calculated with 18 variables, and then six factors were extracted. The differentiation and integration of factorial structure was investigated from the hierarchical factor model. Two factors (muscular power and speed, and flexibility) were extracted at a lower level of rotation. The body fat was found to be one important factor that affects many physical fitness and motor ability elements. The relationships between physical fitness, motor ability and degree of fatness seem to be rather complicated, and a great deal of data should be accumulated for analysis of influence of body fatness in the obese.

The effects of fencing uniforms (U) on thermoregulatory responses were analyzed in both practical field investigation (PFI) and laboratory experiment (LE). In PFI, six fencers (college-aged) performed regular fencing practice wearing U and wearing a short-sleeved shirt and pants (T) in summer. Rectal temperature (Tr), chest skin temperature (Tch), mask temperature (Tmk), heart rate (HR) and sweat rate (SR) were measured during fencing practice. In LE, seven male college-aged subjects performed three sessions of 20-min cycling at light intensity (250 W/m^2) in a room temperature maintained at 28 WBGT (wet bulb globe temperature). Esophageal temperature (Tes), mean skin temperature (Tsk), mean body temperature (Tb), HR, and SR were measured during exercise wearing U and in a semi-nude condition (N). In both PFI and LE, increases in Tch, Tsk, Tb, Tes, Tr and SR were significantly (p<0.001) greater when wearing U than when wearing T and N. In PFI, the maximal value of Tr correlated significantly with the maximal values of Tch (r=0.513, p<0.001) and SR (r=0.635, p<0.001) during practice wearing U and T. In LE, positive correlations between Tsk and Tes (r=0.797, p<0.001), and between Tb and SR (r=0.658, p<0.02) were found at the end of exercise wearing U and N. In PFI, although the Tsk decreased within a few minutes of a decrease in Tmk, a significant relationship between the decrease in Tmk and Tsk or Tr was not observed during fencing practice. These results demonstrate that when wearing U, a higher skin temperature induces core temperature elevation, and higher skin and core temperatures are associated with increases in SR and HR during exercise in a hot environment. Thus, wearing light clothing during exercise, and taking off the fencing jacket and mask during rest periods would be recommended to reduce the heat stress during fencing practice in hot environments.

A study was performed to evaluate the physical exsrcise characterristics of 29 Japanese elite judo athletes by treadmill exercise test. Functional aerobic impairment (FAI), heat rate impairment (HRI) and peripheral circulatory impairment (PCI) in the judo athletes were not significantly different from those of normal sendntary subjects. Howevar, myocardaial aerobic impairment (MAI) was lower than in normal sedentary subjects. %V^O_2max at the anaerobic threahold (AT) was 57.5±3.3% in male, and 57.0±4.3% in female judo athletes. %HRmax at AT was 72.4±3.8% in males, and 75.2±5.3% in females. These findings suggest that functional aerobic capacity and peripheral circulatory function in Japanese elite judo athletes are not significantly different from those of normal sedentary subject, but that judo athletes have high left ventricular function. The blood biochemical profile and urinalysis date revealed that values of muscle injury enzymes plasma uric acid and cholesterol were increased with relatively high freqency in elite judo athletes. Similar data were also obtained in individuals with suspected diabetic nephropathy and rhabdomyolysis.

There have so far been no studies examining the physical fitness and physical activity (PA), measured using objective measures, in homebound elderly people. The purpose of this study was to examine physical fitness levels and PA patterns and evaluate their relationships in homebound elderly people. In 2004, a total of 3964 community-dwelling elderly aged 65 years and over participated in a base line survey. The subject data were directly collected by in-home interviewer. Subjects were defined as being homebound if they went outdoors less than once a week. However, the subjects who could not go out without assistance due to sickness and/or disability were excluded from the analysis. In 2005, 38 homebound (22 men, 16 women) and 70 non-homebound (33 men, 37 women) older adults who participated in the base line survey were selected. Measurements of physical fitness levels and PA patterns measured using an accelerometer, were taken in 2005. The total steps per day did not significantly differ between homebound and non-homebound men and women. The time spent in 1.8 METs activity (corresponding to activity level 1 of the accelerometer) was significantly higher in women than in men for non-homebound and homebound, respectively. The time spent in lower-, moderate-, and high-intensity PA did not significantly differ between homebound and non-homebound men and women, respectively. Handgrip strength, knee extensor strength, leg extensor power, stepping and maximum walking speed were significantly higher in non-homebound than in homebound men and women. These results suggest that the physical fitness levels of homebound were lower than those of non-homebound, but no difference was observed in the PA levels between homebound and non-homebound.
