[Method] Fifteen sheep about one-year old as experimental material were divided into three groups (group A, group B end group C), into whose basal feed 0, 4 and 10 g h/sine were respectively added. After 28 d of feeding, the experimental sheep were all slaughtered for sampling; then total RNAs were extrac- ted from the samples and used to clone GHR and GAPDH genes via retrotrenscription for analyzing the expression abundance of GHR mRNA in Iongissimus dorsi muscle from different treatments. [Result] The expression of GHR mRNA in treatment B was significantly higher than that in treatment A( P 〈0.01 ), and significantly higher then that in treatment C ( P 〈0.05) ; while that in treatment C and treatment A was insignificantly different( P 〉 0.05). [ Conclusion] Addition of lysine into basal feed of sheep could dose-independently improve the expression of GHR gene in Iongissimus dorsi muscle.展开更多

According to Whitehead(2010), physical literacy is defined by motivation, especially by competence-based and interest-based motivation. This point of view is consistent with vast amount of research evidence on children and adolescents' physical activity behavior. In the article I attempt to interpret and operationalize physical literacy from a perspective that children's motivation in physical education is both an innate mental disposition and an acquired/learned attribute. Particularly I rely on the conceptual learning theory and motivation regulation mechanisms of the self-determination theory to argue that in physical education, children should experience tasks that inspire them to embody competence and interest along with self-regulation strategies necessary for developing and sustaining the motivation to move.展开更多

Different exercise training modalities and strategies exist. Two common exercise strategies are high-intensity interval training (HIIT) and moderate-intensity continuous exercise training (MCT). HIIT was first used early in the 20th century and popularized later that century for improving performance of Olympic athletes. The primary premise underlying HIIT is that, compared to energy expenditure-matched MCT, a greater amount of work is performed at a higher intensity during a single exercise session which is achieved by alternating high-intensity exercise intervals with low-intensity exercise or rest intervals. Emerging research suggests that this same training method can provide beneficial effects for patients with a chronic disease and should be included in the comprehensive medical management plan. Accordingly, a major consideration in developing an individual exercise prescription for a patient with a chronic disease is the selection of an appropriate exercise strategy. In order to maximize exercise training benefits, this strategy should be tailored to the individual's need. The focus of this paper is to provide a brief summary of the current literature re^ardin~ the use of HIIT to enhance the fimctional capacity of individuals with cardiovascular, pulmonary, and diabetes diseases.展开更多

This pilot study explored a causal mechanism for such relationship, and hypothesized that when FMS proficiency is improved, enhanced PA uptake will be found in children with and without disability. It was further hypothesized that improving FMS proficiency will have a greater impact on children with disability than those without disability. Methods: Participants include typically developing (TD) children without disability and children with cerebral palsy (CP), who were allocated to FMS training groups (CP-FMS n = 12, TD-FMS n = 13) and control groups (CP-C n = 12, TD-C n = 13). Training groups practiced five FMS (run, jump, kick, throw, catch) in weekly 45-min sessions for 4 weeks. Control groups had their regular physiotherapy (CP) or physical education (TD) sessions. FMS were evaluated using process- and product-oriented measures, and PA was measured using accelerometers, before and after training. Results: It was verified that training groups gained improvements in FMS while control groups did not. No significant changes in weekday PA were found. Increased weekend moderate to vigorous physical activity (MVPA) was found in the CP-FMS group, while decreased weekend sedentary time was found in the CP-FMS and TD-FMS groups. The percentages of participants who exceeded the minimum detectable change (MDC9o) in MVPA and sedentary time were larger in children with CP than in children without disability. Conclusion: The findings suggest that improved FMS proficiency could potentially contribute to heightened PA and decreased sedentary time during weekends for children. Such effect of improved FMS proficiency on PA appears to be greater in those with physical disability than in those without disability. It is recommended that the findings of this pilot study should be further examined in future research.展开更多

Our aim was to systematically review the pathogenetic link between overweight/ obesity, dietary habits, physical activity and GERD, and the beneficial effect of specific recommended changes, by means of the available literature from the 1999 to the present. Obesity, in particular, abdominal obesity, plays a key role in determining GERD symptoms and complications through mechanical and metabolic effects. Controlled weight loss (by diet or surgery) is effective in improving GERD symptoms. No definitive data exist regarding the role of diet and, in particular, of specific foods or drinks, in influencing GERD clinical manifestations. Moderate physical activity seems to be beneficial for GERD, while vigorous activity may be dangerous in predisposed individuals. In conclusion, being obese/overweight and GERD-specific symptoms and endoscopic features are related, and weight loss significantly improves GERD clinical-endoscopic manifestations. The role of dietary behavior, mainly in terms of specific dietary components, remains controversial. Mild routine physical activity in association with diet modifications, i.e. a diet rich in fiber and low in fat, is advisable in preventing reflux symptoms.展开更多

Methods: Training for SG and VG consisted of twice-weekly 15-min sessions with average heart rates (HRs) of ~ 155 and 90 bpm respectively. Pre- and post-measurements of body composition (DXA), phosphocreatine (PCr) on- and off-kinetics, and HR measurements during stand- ardised submaximal exercise were performed. Results: After 16 weeks of training in SG, fat percentage was lowered (p = 0.03) by 1.7%±2.4% from 37.5% ± 6.9% to 35.8% ± 6.2% and the PCr decrease in the quadriceps during knee-extension ramp exercise was attenuated (4% ± 8%, p = 0.04), with no changes in VG or CO (time- group effect: p=0.03 and p = 0.03). Submaximal exercise HR was also reduced in SG after 16 weeks of training (6%± 5% of HRmax, p = 0.01). Conclusion: Short duration soccer training for 16 weeks appears to be sufficient to induce favourable changes in body composition and indicators of aerobic fitness and muscle oxidative capacity in untrained premenopausal women.展开更多

Important issues evolving from neuroscientific research, specifying the identity of human beings, are explained as resulting from the development and stepwise changes of highly dynamic neuronal networks. These conclusions appear to fit the (meta)physical concepts developed by Whitehead, who claims that the elucidation of immediate experience, proceeding from objectivity to subjectivity, is the sole justification of our thought. Both lines of thought assume that our bodily experience, emerging from the perception of various bodily organs, is the basis of our existence.展开更多

The movement power for the cognition is not produced by the contradiction between people's thinking and the objective things, for the thinking and the objective things are not in a same substance, which is Hegel's problem. Then, where is the power for people's cognition from? This paper has a conclusion as this: The "Ego" and the "Nonego" are a pair of contradiction within a person's body. The cognition is a kind of people's movement. So, the cognition is the process moved by the power from the "Ego" and the "Nonego" of a person's body.展开更多

Sand-filtered water in salinity 30 and temperatare 25℃ was used. Twenty-nine fish individuals were divided into three groups: 11 to group 1 (G1) fed on diet 1, 11 to group 2 (G2) fed on diet 2, and 7 to contrast group. Diet 1 was a commercial feed, more valuable in nutrition than diet 2 that similar to natural detritus. The results show the intake phosphorus (IP) of G1 was significantly higher than that of G2, and both increased linearly with body size at a certain amount of diet. The retention phosphorus (RP) in fish of G1 was lower than G2. The relationship between retention phosphorus and body size was positive and stronger in G2. Significant difference in faecal phosphorus (FP) was found between G1 and G2. Body size significantly impacted the excretion phosphorus (EP) in G1 but G2. The loss of intake phosphorus in G1 was 10.83-20.27 mg per g fish weight gain, higher than that in G2 for 6.63-9.56. Of the phosphorus, about 10% was allocated into growth, 50% in faeces, and the rest lost in excretion. The main part of phosphorus was lost in faeces but excretion. The phosphorus budget of the fish could be described as 100IP = 7.40RP + 47.39FP + 36.63EP (Diet 1) or 100IP = 11.93RP + 56.64FP + 21.76EP (Diet 2).展开更多
