In the present research, first we evaluated the association between urban area size and commuting modes with physical activity among working people. Then we investigated the longitudinal effects of urban area size and commuting modes on increased physical activity due to health guidance intervention. The subjects were 401 male employees (aged 46.3±7.8) of A corporation, and were split into two groups, metropolitan area group (N=235) and local area group (N=166), based on the population density of place of work. IPAQ-E was used for evaluation of walking environments, and physical activity was assessed using pedometers. The intervention consisted of an exercise-focused health guidance over the course of one year. The cross-sectional study admitted that in comparison with the local area group the metropolitan area group had more than physical activity (p<0.01). Not only the size of urban area but commuting modes were significantly related to the level of daily physical activity (p<0.001). In longitudinal study, regarding the effects of the intervention for the physical activity, the study showed the possibility that urban area size was not directly effective but traffic safety in residential area (p<0.05) and willingness to take a walk (p<0.01) were effective. The cross-sectional study suggested that the size of the urban area and commuting modes had independently an effect on the physical activity of working people. The longitudinal study, on the other hand, suggested that the size of the urban area and commuting modes may not any direct influence on the effects of physical activity intervention.

【Purpose】A leg press generally included in a weight training program to develop the quadriceps. However little is known about the mechanism of the load in lower extremity by the different knee alignment. The purpose of this study is to compare the muscle activity in the different knee alignment during leg press exercise. 【Methods】Four normal knee and Five genu varum performed the leg press using three stance of narrow, medium and wide stance with the load of 75%/1 RM. Surface EMG date were collected (l000Hz) from vastus medialis (VM), vastus lateralis (VL), rectus femoris (RF), adductor longus (AL), biceps femoris (BF), tibialis anterior (TA), gastrocnemius (GAS), soleus (SOL). Integrated EMG (iEMG) values were calculated for each muscle during each rep. A video camera recorded the performing form during leg press from the frontal plane. 【Results and Discussion】As the leg press was to strengthen of the thigh muscle, VM, VL and RF of both groups worked strongly. However SOL of genu varum worked as strong as the level of activity of the thigh, iEMG of the SOL showed low value significantly by using wide stance. When the genu varum group performed maximal knee flexion using the narrow, their ankle was valgus on the video screen. This result may become cause of SOL higher activity during leg press. From this we can derive the argument that it will be necessary to take that stance into consideration when athletes who are genu varum performs leg press. (Jpn. J. Phys.

A study was conducted to evaluate the chronic effects of regular physical activity on nonspecific and specific immune responses. Male Fischer rats (SPF) exercised voluntarily on running wheels for 4 months, and were then injected intraperitoneally with sheep red blood cells (SRBC), followed by measurement of the host defense functions at -2 d, 3h, 24h and 4 d of antigen stimulation. The following results were obtained:<BR>1) The ability of circulating neutrophils to produce superoxide measured by the spontaneous NBT test showed an earlier and higher (p<0.05) rise after SRBC injection in the exercise group, suggesting that neutrophils were activated <I>in vivo</I> more promptly against foreign-body invasion. This might reflect a priming response of neutrophils at the early phase of SRBC-induced host defense reactions modulated by the previous regular exercise.<BR>2) The ability of neutrophils to produce superoxide in response to <I>in vitro</I> stimulation with <I>Staphylococcus aureus</I> 209 P was markedly reduced during inflammatory response in the sedentary group, whereas that in the exercise group was maintained at a constant level. The value at 4 d after SRBC injection in the sedentary group was decreased to more than 20% below the baseline (p<0.02) . In addition, a significantly (p<0.02) lower value than that in the exercise group was shown, although phagocytic activity was similar in the two groups. This suggested that neutrophil bactericidal activity was decreased in the sedentary group.<BR>3) Plasma IgG levels in the exercise group were consistently and significantly (p<0.0001) higher by about 30% than those in the sedentary group, regardless of SRBC injection. This suggested an enhanced host defense status by regular exercise.<BR>4) The specific humoral immune response to SRBC injection was assessed in terms of hemagglutination and plasma IgM levels, but no significant differences were shown between the groups.

The purpose of this study was to investigate the influence of physiological factors which effect oxygen kinetics and energy system contribution on the power of Wingate test (WT), with focusing on the difference of aerobic capacity. Twenty three male track and field athletes (sprinters, long distance runners and decathletes) performed the WT on electromagnetic-braked cycle ergometer. The applied resistance was 7.5% of body weight, and the duration was 60 seconds. Moreover, aerobic capacity (maximal oxygen uptake [VO2max]) was determined by an incremental test, and anaerobic capacity (maximal accumulated oxygen deficit [MAOD]) was determined by a supramaximal constant load test. The oxygen uptake during each test was recorded by a breath-by-breath method. The participants were divided into two group which was high VO2max group (High group; n = 11) and low VO2max group (Low group; n = 12). In the results, although the VO2max was significantly higher in the High group, the MAOD was not significantly different between two groups. The oxygen uptake during WT was significantly higher in the High group, and the accumulated oxygen deficit during WT was significantly higher in the Low group. The aerobic contribution was significantly higher in the High group than in the Low group. In contrast, the anaerobic contribution was significantly higher in the Low group than in the High group. These results suggest that by the difference of aerobic capacity, aerobic and anaerobic energy supply contribution was different in WT.

A study was conducted to investigate the effect of exercise intensity on the recovery of autonomic nervous activity after exercise. Ten subjects performed four kinds of 10-min cycle exercise with target heart rates of 100, 120, 140, and 160 beats/min (THR 100, THR 120, THR 140 and THR 160, respectively) following 5 min of exercise to increase the heart rate to the target level. The beat-by-beat variability of the R-R interval was recorded throughout the experiment including the 5-min pre-exercise control period and the 30-min recovery period. Spectral analysis (fast Fourier transform) was applied to every 5-min R-R interval data set before, during ( 5-10 min) and after exercise at the target heart rate. The low- (0.05-0, 15 Hz : P1) and high- (0, 15-1.0 Hz : Ph) frequency areas were calculated to evaluate sympathetic (SNS) and parasympathetic (PNS) nervous activities as P1/Phand Ph, respectively. During exercise, SNS of THR 160 was significantly higher, and PNS of THR 140 and THR 160 was significantly lower than the respective pre-exercise values (p<0.05) . Althouglt all indicators recovered to, or overshot the pre-exercise values at 20-30 min after THR 100 and THR 120, heart rate and SNS were still higher and PNS was still lower than the pre-exercise value after THR 160. These results suggest that the recovery of cardiac autonomic nervous activity is slower after high-intensity exercise than after low-intensity exercise, and that the recovery of autonomic nervous activity after acute exercise does not always corrrespond linearly on the exercise intensity.

This study aimed to clarify the differences in cardiorespiratory and metabolic responses to body mass-based front lunge and squat exercises with relation to muscular activity. Seven healthy adult males performed 200 times body mass-based squat and front lunge exercises. During the exercises, oxygen uptake, heart rate (HR), blood lactate concentration (La), ground reaction force were measured. Oxygen uptake was divided by body mass (VO2). VO2 and HR was normalized to maximal VO2 (%VO2max) and maximal HR (%HRmax) obtained from an incremental load test. Electromyograms (EMGs) during the two exercises were recorded from the vastus lateralis (VL), rectus femoris, vastus medialis (VM), biceps femoris, gluteus maximus (GM). EMG amplitudes during both exercises were normalized to those during maximal voluntary contraction, and expressed as relative value (%EMGMVC). Time that cardiorespiratory parameters became stable was 4-6 min in both exercises. VO2, %VO2max, metabolic equivalent, were higher in the front lunge than the squat. No significant differences in HR, %HRmax and La were found between both tasks. %EMGMVC in VL, VM and GM were higher in the front lunge than the squat. These current findings indicate that 1) body mass-based squat and front lunge exercises are physiologically of more than moderate intensity, and 2) the cardiorespiratory responses to body mass-based front lunge are greater than those to body mass-based squat. This may be due to the difference in muscular activities of VL, VM and GM during the tasks.

Although street dance quickly became popular in Japan, and the population of street dancers is increasing, there is limited information on injuries sustained during street dance in Japan. The purpose of this study was to investigate the epidemiology of injuries in street dancers in Japan. One hundred and ninety-five Japanese street dancers (92 intermediate, 35 advanced, and 68 expert dancers) participated in this study. A questionnaire survey concerning the injuries sustained during dancing was conducted over a 3-month period. The main results were: (1) Sixty-one dancers reported a total of 72 injuries, and injury rate was 0.56 per 1000 players-hours; (2) Ankle injuries accounted for 45.8% of the reported injuries; (3) Dancing proficiency level was related to the occurrence of injury, and the occurrence was significantly higher for the expert dancers; (4) The duration of warm-up was related to the occurrence of pains. These findings provide fundamental information that may contribute to the development of injury prevention in street dance.
