In this study, we examined applicability of existing equations to predicting the body surface area (BSA) of children, and newly developed prediction equations for the BSA of children. BSA of 87 children of both genders (7∼12 yr) was determined by the three-dimensional photonic image scanning (3DPS), which was used as reference. BSA predicted using existing equations yielded overestimation or underestimation and/or a systematic error with respect to the reference. BSA prediction equations for boys and girls were developed using height and body mass as independent variables for the validation group and cross-validated for another group. The standard errors of estimation of the prediction equations were 105 cm2 (0.9 %) for boys and 158 cm2(1.4 %) for girls. In the cross-validation group, there was no significant difference between the predicted and measured values without systematic errors. These findings indicate that existing equations cannot accurately predict BSA of children, and that the newly developed prediction equations are capable of predicting BSA of children with adequate accuracy.

This study was conducted to examine the reliability of three-dimensional photonic image scanning (3DPS) for measuring body surface area (BSA), and formulate equations for predicting BSA based on 3DPS. The surface area (SA) of a cylinder with known SA and BSA of 7 males were repeatedly measured by 3DPS. BSA was determined by 3DPS for 122 subjects (25–76 yrs). BSA prediction equations for both genders were developed for the validation group (16 males and 45 females) using body height and mass as independent variables, and were cross-validated for the cross-validation group (16 males and 45 females). The standard error of measurement was 2.2cm2 (0.16%). The coefficients of variation (CV) for repeated measurements of SA were less than 0.2%. The BSA of subjects did not differ significantly on any given day nor between days, with a CV of less than 1%. The coefficient of determination and standard error of estimation of the prediction equations were 0.98 and 183cm2 (1.1%), respectively, for males and 0.98 and 204cm2 (1.3%), respectively, for females. There was no significant difference between the predicted and measured values. In the cross-validation group, there was no significant difference between the predicted and measured values without systematic errors. These findings indicate that 3DPS is reliable for measuring BSA, and the formulated equations are valid and applicable to individuals within a wide age-range.

Japan is the only country that has implemented a nation-wide measure for functional disability leading to long-term care needs in old ages. Thus, there are no previous national trials that we can refer to. Whether its disability prevention measure succeeds or not will depend on our own efforts toward the future. In this paper, I will overview a 10-year experience with the disability prevention program launched in 2006, and then will point out the relevant issues in realizing the prevention of functional disability in old ages for exercise and sports scientists.

Purpose of this study was to examine the recovery process of delayed onset muscle soreness, jump performance, force to contact with the ground and lower limbs movement after intensive jump exercise (IJE), and the relationships between muscle soreness, changes of jump performance and lower limbs movement. Nine males who have experience in special jump exercise participated in this study voluntarily. For the measurement, subjective investigation of the muscle soreness, drop jump performance using a 30 cm high box [jump height, contact time and drop jump index (jump height / contact time)], ground reaction force and movements of lower limbs. This measurement was carried out before IJE (Pre), and at 4 hours (P4), 24 hours (P24) and 72 hours (P72) after IJE. Main results are as follows ; at the time of P24 when intense muscle soreness appeared, significant jump height decreases and contact time increases were shown, and the jump index decreased markedly. This decrease of performance correlated to the change of knee and ankle joint movements during the eccentric phase. At P4, for a subject who felt strong muscle soreness, the decrease of jump height and jump index were considerable. At P72, most subjects recovered to the levels of jump height and contact time to the Pre level. The findings reveal that the jump performances are related to the degree of delayed onset muscle soreness.

Exercise intensity has been identified as a major determinant of the excess post-exercise oxygen consumption (EPOC). However, no studies have compared the prolonged EPOC after supramaximal intermittent exercise and supramaximal continuous exercise. Six young healthy male [age=26±3 (mean±SD) yr ; stature=175.4±5.7 cm ; body weight=66.8±6.7 kg ; maximal oxygen uptake (VO2max)=44.1±8.5 ml/kg/min] xercised on separate days on a cycle ergometer at two equated total energy expenditures (intermittent exercise : 7×30-second intervals at 150%VO2max with intervening 15-seconds rest periods ; continuous exercise : 5 min at 105%VO2max) and then sat quietly in an armchair for 3h. A control trial without any exercise was also performed in a counterbalanced research design. The VO2, carbon dioxide output (VCO2), pulmonary ventilation (VE), respiratory exchange ratio (RER), heart rate (HR) and blood lactate concentration (LA) were measured before exercise, during exercise and during the 3-h recovery period. The mean VO2 after intermittent trial at 150%VO2max were higher than these of the control trial and the continuous trials at 105%VO2max for 3-h recovery periods (p<0.05). The 3-h EPOC value for intermittent exercise trial (10.5±2.4L) was significantly greater than that of continuous exercise trial (4.8±2.7L) (p<0.05). The mean RER values for intermittent exercise trial were significantly lower than those of the control trial during 60-180 min post-exercise (p<0.05). We examined the effect of supramaximal exercise intensity on the magnitude of 3-h EPOC after 12-fasting. In the present study, 3-h EPOC was significantly greater for supramaximal intermittent exercise compared with the supramaximal continuous exercise when the amounts of work output performed are same. Therefore, our results indicate that exercise intensity may be a primary factor of 3-h EPOC even in a supramaximal exercise and that one of mechanisms for the 3-h EPOC would be related to the promoted lipid metabolism.

Energy balance in human body undergoes constant change, leading to a change in the weight and body composition throughout life. Energy balance at a particular time point is influenced by the psychological, physiological, sociological, and environmental factors of that moment. In addition, the regulation of homeostasis continuously monitors and maintains the energy balance; however, it complicates the identification of factors influencing the energy balance. For understanding these factors, creating a model with comprehensive factors and testing it among a substantial number of individuals for dynamic changes in the energy balance may be warranted. However, till date, to the best of our knowledge, no studies report on comprehensive modeling, including homeostasis and the other factors. Thus, at this moment, summarizing previous studies for further research is required. Accordingly, this review summarizes 1) the basic factor of energy expenditure and intake; 2) interactive relationship between energy expenditure and intake; and 3) energy expenditure and intake during dynamic changes in the body weight caused by events such as overfeeding, underfeeding, growth and aging, and pregnancy.

Physical fitness including muscle strength and endurance capacity varies substantially among individuals. Physical activity level and exercise behavior also vary among individuals. Many family studies and studies on twins have reported that genetic factors are responsible for heterogeneity in fitness-related traits. However, there is much dispersion in heritability, as previously reported. A systematic review was performed to determine the extent of heritability in physical fitness. A literature search was conducted through PubMed using the following keywords: (heredity or heritability) and ("muscle strength" or "muscle contraction" or endurance or athlete* or fitness or exercise) and (twin* or family). Finally, 43 articles that included 137 phenotypes met the criteria. Only one article focused on the heritability of athletic status. With respect to muscle strength, 23 articles and 54 phenotypes were collected, and showed a range of heritability of 0%-98% (mean: 55±22%). This heterogeneity was partly explained by the ages of subjects. With respect to endurance capacity, 13 articles and 28 phenotypes showed heritability of 0%-93% (mean: 54±25%). The considerable degree of variability in heritability of fitness-related traits may depend on age, sex, race, and environmental factors. Therefore it is necessary to investigate the interaction between genetic factor and factors other than genetic factor. On the other hand, with respect to exercise behavior or physical activity level which is important for improving the physical fitness or health status, the heritability of 0%-85% has also been reported. That is, the genetic factor plays a role in not only physiological phenotypes but also behavioral phenotypes. Understanding of these genetic factors and their mechanisms will lead to improvement in physical fitness or encouragement of physical activity/exercise behavior.
