ABSTRACT
A study was performed to evaluate the physical capacity of elite female volleyball players from Kyushu Bunka Gakuen Senior High School (Kyu. B. G.) . Twenty-four players were examined for body composition (underwater weighing), cardiorespiratory function (VO<SUB>2</SUB>max and O<SUB>2</SUB>debtmax by treadmill exercise test) and skinfold thickness, from 1988 to 1989.<BR>These measurements were compared with those of 16 second-class players from Nagasaki Prefecture, and also with the results of other investigations.<BR>The results were as follows :<BR>1. The mean parameters for the Kyu. B. G, players were : age, 17.5 yr ; height, 168.3 cm ; weight, 59.8 kg ; percentage body fat (%Fat ), 17.9% ; lean body mass ( LBM), 49.0 kg ; LBM/ Ht, 29.1 kg/m ; sum of eight skinfold thicknesses, 109.1 mm ; VO<SUB>2</SUB>max, 2.71 l/min, 45.7 ml/kg· min ; O<SUB>2</SUB>debtmax, 5.69l, 94.8 ml/kg.<BR>2. The average %Fat of the Kyu. B. G, players was significantly lower than that of the second-class players from Nagasaki Prefecture.<BR>3. The average VO<SUB>2</SUB>max (ml/kg·min) and O<SUB>2</SUB>debtmax (l, ml/kg) of the Kyu. B. G, players were significantly higher than those of the second-class players.<BR>4. The average %Fat and VO<SUB>2</SUB>max (ml/kg·min) of the Kyu. B. G, players were similar to those of Japan League and All Japan volleyball players.<BR>5. When the progress of physiological function due to training for 11 months was examined in five Kyu. B. G, players, the average VO<SUB>2</SUB>max (ml/kg·min) showed a significant increase of approximately 8%.<BR>These results indicated that the Kyu. B. G, players had a superior body composition, aerobic work capacity and anaerobic work capacity, equal to those of top volleyball players in Japan.
ABSTRACT
A study was performed to evaluate the physiological function of elite senior high school soccer players (Kunimi) . Forty-six players were evaluated for cardiorespiratory function (maximum oxygen uptake : Vo<SUB>2</SUB>max, maximum oxygen debt : Max O<SUB>2</SUB> debt), body composition (underwater weighing) and skinfold thickness, all parameters being measured four times over a two-year period.<BR>The following means were recorded : age, 17.8 yr ; height, 173.0 cm ; weight, 65.8 kg ; percentage body fat (%Fat), 10.0%; lean body mass (LBM kg), 59.2 kg ; LBM/Ht (kg/m), 34.2 ; sum of eight skinfold thicknesses, 63.5 mm ; Vo<SUB>2</SUB>max, 60.0 m<I>l</I>/kg⋅min ; maximum ventilation (V<SUB>E</SUB>max, BTPS), 136.8<I>l</I>/min ; maximum oxygen debt ; 8.2<I>l</I>, 124.8 m<I>l</I>/kg.<BR>Results for percentage body fat, Vo<SUB>2</SUB>max (m<I>l</I>/kg⋅min) and Max O<SUB>2</SUB> debt (m<I>l</I>/kg) were compared with values found in other soccer players at various levels.<BR>In summary, one of the most outstanding attributes of the Kunimi senior high school soccer players was a high level of both aerobic power and anaerobic power.
ABSTRACT
Investigation on the working time, energy expenditure and fatigue were carried out for members of three families engaged principally in raising silk worms.<BR>Group examinations of physical conditions and blood constituents and survey of nutritional intake were performed on the residents, including the above families, in a community in Fukueisland, Nagasaki-prefecture.<BR>The results were as follows;<BR>1) The average values of energy expenditure on a most busy day in a raising period of silk worm calculated to be 3150 kcal (max. 3500 kcal) for males, 2340 kcal (max. 2890 kcal) for females of the above three families. Their working times on this day were about 14 hours.<BR>2) The physical fatigue of the subjects was estimated by means of Fliker frequency, near point and threshold of patellar reflex. Remarkable changes of these values were found, suggesting the heavy physical load of the raising works, and the changes were more remarkable in olders and females than in youngers and males.<BR>3) Donaggio's reaction and Na/K in the first urine of morning were investigated at an interval of five days during one period of silk worm raising.<BR>The Donaggio's reaction values were increased about two times higher in the latter term, on the other hand Na/K dropped in the former term of the period.<BR>4) The group examinations of the inhabitants in the community showed that the body fat of silk raising farmers were fewer than that of the farmers engaged in other kinds of farming reported by the present authors.<BR>Blood values (Ht, Hb and TP) of them in 1975 were lower than in 1974, because one more raising period was added and so the physical load of them might be greater in '75 than in '74.<BR>5) The nutritional intakes of silk raising farmers were almost as same as these of the farmers in other districts.
