The physiological characterisitics of 28 elite synchronized swimmers (SSs) were studied. The examined variables were body composition, aerobic power(V˙O_2max) including lactate threshold(V˙O_2@LT) and blood properties. The SSs were superior to non-athletic(untrained) women in aerobic power. Furthermore, the significant 10.7% increase(46.3±4.2 to 51.3±4.3ml/kg/min) in V˙O_2max and 20% increase(25.2±2.7 to 30.5±3.2ml/kg/min) on V˙O_2@LT were observed 1 year after, while the % body fat was similar to nonathletic women. Interestingly sport anemia was not found in the elite SSs. Except both high %fat and sport anemia, these results suggested that physiological profiles of SSs were similar with those of long distance runners.

The purpose of this study was to elucidate the effects of whole-body vibration training (WBVT) on knee function and physical performance in middle-aged and older Japanese women who suffered from knee osteoarthritis (OA) and knee pain. Thirty-eight middle-aged and older Japanese women (aged 50-73 years) with knee OA and knee pain were divided into two groups: (1) a WBVT group (n = 29) engaging in WBVT 3 times a week for 8 weeks, and (2) a control group (C group, n = 9) performing exercises at home. The WBVT program consisted of a warm-up, strength training mainly of the quadriceps and their surrounding muscles and cool-down exercises. In the WBVT group, there were no dropouts, and there were significant improvements in the physical function (Cohen’s d = 0.28) and total score (Cohen’s d = 0.25) of Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). There were also statistically significant improvements in all lower-extremity function tests (5-times sit-to-stand, timed up and go, standing time from a long sitting position, sit and reach, 4-way choice reaction time; Cohen’s d = 0.34-1.24). The item that changed significantly in the C group, however, was only the sit and reach (Cohen’s d = 0.52). In addition, all items in the Japanese Orthopaedic Association Score (JOA score) improved significantly (Cohen’s d = 0.63-0.67) in the WBVT group. In conclusion, the 8-week WBVT program can safely improve knee function and physical performance in middle-aged and older Japanese women who suffer from knee OA and knee pain.

Body fat generally has been considered to be liable to physical fitness and motor ability. However, very few studies have been done on the relationships between body fat and physical fitness and motor ability. The purpose of this study was to clarify the relationships between percent body fat(%fat) and selected motor ability elements. The subjects were seventy-nine boys and ninety-eight girls aged 10-11 years. Selected motor ability variables were grip strength, back strength, 50-meter dash, running long jump, vertical jump, belly grind, side step, trunk flexion, trunk extension, modified chinning, zigzag dribble, softball throw, and step test. Skinfold thickness was measured at three sites(triceps, subscapular, abdomen)using an Eiken-type caliper. Percent body fat was measured using a tetrapolar bioelectircal impedance plethysmograph(Selco 891). Negatively affected variables by %fat were those which involved muscular power and coordination, while muscular strength was positively related with %fat. Flexibility variables were found not affected by %fat. The subjects were grouped according to %fat in order to further examine the effects of %fat on motor ability. The groups were less than 10%fat(lean), 10∼20%fat(standard)and greater than 20%fat(obese) in boys, and less than 15%fat(lean), 15∼25%fat(standard)and greater than 25%fat(obese) in girls. The results of comparision among groups clearly indicated that the obese groups were poorer in muscular power and coordination but greater in musular strength. The body fat may be one important factor that affects on many motor ability elements. The relationships between 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.

To validify the physiologic availability of the playport game, we examined the metabolic and ventilatory responses of second and fourth grade boys(n=6) and adult men(n=4) during playport games. In children, maximal oxygen uptake(V˙O_2max) and lactate threshold(V˙O_2 LT) measured on treadmill, averaged 47.3±3.4 ml·㎏^1·min^1 and 27.6±1.9 ml·㎏^1·min^1, respectively. The playing at the 8 min playport elicited an average of 44.1±5.2 ml·㎏^1·min^1 during the last 4 min after starting the play, which corresponded to approximately 90% of V˙O_2max. When compares the lactate (La) levels between children and adults, the children has significantly lowered La at 2.44±0.6 mM/ l and below than the adult groups. The present results suggested that children experience high intensity physical activity during playport game seemingly contributed to the enhancement of cardiorespiratory function.

[Purpose] To date, there have been no reports on whether weight reduction causes decreases in muscle mass, muscle strength, or physical performance that could lead to health problems. Thus, in this pilot study, we investigated the appropriateness of the changes in muscle mass, muscle strength and physical performance after weight reduction. [Methods] Obese men who completed a weight reduction program to decrease and maintain a body mass index (BMI) of less than 25 kg/m2 for one year were recruited for the study. One year after the completion of a weight reduction program, the participants’ muscle mass, muscle strength, and physical performance were compared with those in a reference group composed of individuals whose BMI was less than 25 kg/m2. Whole-body scanning was performed using dual-energy X-ray absorptiometry to analyze muscle mass. Handgrip strength and knee extensor strength were measured to evaluate arm and leg muscle strength, respectively. For physical performance, a jump test was employed. [Results] The results showed that the biceps, triceps, subscapular, and suprailiac areas of professional fashion models were significantly thinner than those of women in general (p<.001), and that their waist size was also significantly smaller (p<.001). However, hip circumference showed no significant difference. Body mass index, waist-to-hip ratio, and body fat (%) in professional fashion models were significantly lower than those in women in general (p<.001), while the body density in professional fashion models was significantly greater (p<0.001). [Conclusion] Weight reduction participants showed an average reduction in body weight of -16.47%. Normalized arm muscle mass and handgrip strength were significantly greater in the weight reduction group than in the reference group; however, no significant differences were detected between the two groups with respect to the other variables. After one year, there were no significant differences between the two groups.

It has been well known that maximal oxygen uptake(V˙o_2max) is ca-nsidered a good indicator or ca diorespiratory fitness of aerobic power. However, direct measurement of V˙o_2max requires expensive laboratory equipments such as oxygen analyzer and carbon dioxide analyzer. The purpose of this study was threrfore to predict V˙o_2max from a simplified questionnaire pertaining to the evaluation of cardiorespiratory endurance and to evaluate cross-validation of the developed questionnaire could be generalized to other samples. The questionnaire consisted of 5 Question concerning the current walking ability, long-running ability in youth, current exercise habits, responses to rush-up of stairs(imaginatory response), and body composition. The V˙o_2max estimated by our questionnaire was not significantly different from the criterion measured V˙o_2max. Test-retest reliability of the questionnaire on 31 subjects was 0.92 as determined by Spearman's correlation coefficient. The correlation between the measured and V˙o_2max(ml/kg/min) estimated from the simplified questionnaire was 0.868(SEE=5.12ml/kg/min) in men(n=201) and 0.853(SEE=5.54ml/kg/min) in women(m=127), indicating either a relatively high relationship between the two variables. The cross-validity of the questionnaire using directly measured V˙o_2max as the criterion was very good(r=0.874). These results suggested that the indirect assessment of cardiorespiratory fitness from questionnaire survey accurately estimates V˙o_2max, and is safe and suitable for measuring aerobic power in epidemiologic studies of people between the ages of 30-70 yr. However, the slightly less acurate V˙o_2max prediction were observed in the highly active men and elderly.
