[Purpose] The purpose of this study was to examine the characteristics of physical fitness, lifestyle, and appearance of unidentified complaints in young children exhibiting hyperactivity and impulsive behavior. [Method] The subjects of this study were 628 young children. We analyzed 21 items related to children's behavior, lifestyle, and unidentified complaints, and 5 physical fitness items. We used these items to compare normal young children and young children exhibiting hyperactivity and impulsive behavior. [Results and Discussion] The proportion of young children exhibiting hyperactivity and impulsive behavior was slightly larger than that in the preceding research. From the results, it seems that a considerable number of children who were not medically diagnosed exhibited hyperactivity and impulsive behavior. In addition, it was confirmed that the lifestyle of these young children was significantly unhealthier than that of normal young children. We think that young children need assistance in order to ensure both appropriate behavior and lifestyle. It is necessary to examine the influence of these behavior and lifestyle upon physical fitness in older children.

Curcumin, from turmeric, has been investigated for its anti-inflammatory activity. We investigated the effects of giving the curcumin on delayed onset muscle soreness and muscle function following eccentric exercise. We used a randomized, double-blinded, placebo-controlled, crossover trial with two 8-day testing phases and a 3-month washout period. Ten healthy male subjects performed two bouts of eccentric exercise involving elbow flexion (6 sets of 4 repetitions) 30 min after curcumin (150 mg) or placebo was given. Perceived muscle soreness, maximal voluntary isometric elbow flexor strength, elbow range of motion (ROM), and upper arm circumference were assessed before, immediately post (0), 24, 48, 72, and 96 h following exercise. All parameters changed significantly (p<0.05) in both groups at 0 h. There was significantly (p<0.05) less perceived muscle soreness and higher maximal isometric strength in the curcumin group compared with the placebo group after 48, 72, and 96 h. There was a significant (p<0.05) smaller reduction in elbow ROM in the curcumin group compared with the placebo group at 0, 24, 48, 72, and 96 h. No differences were observed in upper arm circumference. This suggests that curcumin can alleviate muscle soreness and enhance muscle recovery after exercise-induced muscle damage.

This study aimed to clarify the exercise intensity of the motor learning scenes in elementary school physical education class. The subjects were 28 children (16 boys and 12 girls) in the 5th grade. We examined all five exercises of long jump, physical expression, tag rugby, hurdle run and tee ball. Lifecorder GS (SUZUKEN Co.,Ltd.) was used to measure exercise intensity. The results of the analysis showed a significant difference in exercise intensity among individuals. The analysis revealed difference in exercise intensity between tag rugby and tee ball, between tag rugby and long jump, and between physical expression and long jump (p<0.05). About differences among the average of exercise intensity in exercise, hurdle run was significantly higher than tag rugby, physical expression, and tee ball, and the long jump was significantly higher than the tee ball(p<0.05). In each exercise, the proportion of motor learning scenes was 75.4%, 70.7%, 62.8%, 58.0%, and 43.9%, for tee ball, physical expression, long jump, hurdle run, and tag rugby, respectively. These findings suggest that exercise intensity did not increase when motor learning scenes were secured. The incorporation of high-intensity activities in exercises with low exercise intensity may be necessary.

Masked obesity is the presence of obesity based on percent body fat (%BF) when the body mass index (BMI) shows an absence of obesity. To examine the relationship between masked obesity and arteriosclerosis risk factors, we compared both serum lipid levels and the prevalence of hyperlipidemia in male and female high school freshmen with and without masked obesity. Subjects consisted of 403 male and 326 female high school students aged 15〜16 years. Of these, 34 (8.4%) males and 36 (11.0%) females had masked obesity, defined as 17≦BMI<23.60 and %BF ≧25% in males, and 17≦BMI<24.17 and %BF≧30% in females, while the remaining 300 males and 246 females were not obese, having 17≦BMI<23.60 and %BF<25% and 17≦BMI<24.17 and %BF<30%, respectively. For both sexes, serum total-cholesterol (TC), low-density lipoprotein cholesterol (LDLC), triglycerides and the arteriosclerotic index (AI) were significantly higher (p<0.05〜0.01) in those with masked obesity. And many of the subjects with masked obesity had abnormal levels of TC, LDLC and AI, compared with those who were not obese (p<0.05〜0.01). Additionally, we compared both serum lipid levels and the prevalence of hyperlipidemia between subjects with masked obesity and control groups with the same BMI values. As a result, subjects with masked obesity had high serum lipid levels and a prevalence of hyperlipidemia. These results support the existence of masked obesity and suggest that masked obesity is associated with increased serum lipid levels, and thus could be a risk factor for arteriosclerosis in male and female high school freshmen.
