Universities put emphasis on cultivation of traditional concept culture, when setting up sports courses; they will focus on martial arts, Taijiquan and other Chinese traditional sports events so as to let students to better understand Chinese culture. However, Taijiquan course development level in all kinds of universities is not the same. The paper takes Beijing city nineteen different types of universities as examples, from the perspectives of Taijiquan course setting status professional teachers proportions and non-professional teachers' proportions, utilizes AHP method to research on Taijiquan course developing conditions. Universities types include first-tier universities, secondtier universities, third-tier universities and specialized colleges these four types. Research results shows that Taijiquan course best development universities are first-tier universities, secondly is second-tier universities. Thereupon, it indicates Taijiquan course developing conditions are related to universities strength. Copyright © 2016 American Scientific Publishers All rights reserved.

Along with social progress and the development of science and technology, people's material life has been greatly improved, so there appears a growing number of obese youth; the incidence of this group is higher, the impact on families and community is larger, and thus many experts put forward their own views for weight loss exercise. Through the study on the relationship between the walking and running sport - energy consumption - fat reduction, this paper proposes a weight loss strategy by prolonged low-intensity exercise from a optimal mathematical point of view; in order to study the relationship walking and running and energy, the paper first studies the relationship between the heart rate and the two respectively; in the study course it uses a non-equidistant Logistic model, and obtains reasonable results through the model; in addition this paper also establishes the optimization model of fat consumption and in constraint condition of stride frequency in order to verify the reliability of Logistic model; moreover, it establishes the mechanism model of fat consumption, the results validate the error between the two is within 10%, obtains the optimal exercise strategy with exercise time 120 minutes and stride frequency 140l/min; in this mode the exercise can reach a theory effect of weekly weight loss 49g; the experiment proves that the result is a safe range for weight loss, which provides a theoretical basis and methods for the weight loss exercise of majority of obese youth. © 2013 Trade Science Inc. - INDIA.

The aim of the paper was to follow up major physiological reactions, provoked by heat stress during dry and wet sauna baths. A physical strain index and subjective estimation of heat comfort of subjects who had not taken sauna baths before was also evaluated. Ten healthy males aged 25-28 underwent a dry sauna bath and then after a one-month break they underwent a steam sauna bath. Each time, they entered the sauna chamber 3 times for 15 minutes with five-minute breaks. During breaks they cooled their bodies with a cold shower and then rested in a sitting position. Before and after the baths, body mass and blood pressure were measured. Rectal temperature and heart rate were monitored during the baths. The physiological strain index (PSI) and cumulative heat strain index (CHSI) were calculated. Subjects assessed heat comfort by Bedford's scale. Greater body mass losses were observed after the dry sauna bath compared to the wet sauna (-0.72 vs. -0.36 kg respectively). However, larger increases in rectal temperature and heart rate were observed during the wet sauna bath (38.8% and 21.2% respectively). Both types of sauna baths caused elevation of systolic blood pressure, but changes were greater after the dry one. Diastolic pressure was reduced similarly. Subjective feelings of heat comfort as well as PSI (4.83 ± 0.29 vs. 5.7 ± 0.28) and CHSI (76.3 ± 18.4 vs. 144.6 ± 21.7) were greater during the wet sauna bath. It can be concluded that due to high humidity and reduction of thermoregulation mechanisms, the wet sauna is more stressful for the organism than the dry sauna, where the temperature is higher with low humidity. Both observed indexes (PSI and CHSI) could be appropriate for objective assessment of heat strain during passive heating of the organism.

Background The aim of this study is to assess if the application of different methods of active recovery (working the same or different muscle groups from those which were active during fatiguing exercise) results in significant differences in muscle performance and if the efficiency of the active recovery method is dependent upon the specific sport activity (training loads). Design A parallel group non-blinded trial with repeated measurements. Methods Thirteen mountain canoeists and twelve football players participated in this study. Measurements of the bioelectrical activity, torque, work and power of the vastus lateralis oblique, vastus medialis oblique, and rectus femoris muscles were performed during isokinetic tests at a velocity of 90°/s. Results Active legs recovery in both groups was effective in reducing fatigue from evaluated muscles, where a significant decrease in fatigue index was observed. The muscles peak torque, work and power parameters did not change significantly after both modes of active recovery, but in both groups significant decrease was seen after passive recovery. Conclusions We suggest that 20 minutes of post-exercise active recovery involving the same muscles that were active during the fatiguing exercise is more effective in fatigue recovery than active exercise using the muscles that were not involved in the exercise. Active arm exercises were less effective in both groups which indicates a lack of a relationship between the different training regimens and the part of the body which is principally used during training. © 2016 Mika et al.

Objectives: The increasing problem of population aging requires appropriate economic and health-related measures to mitigate its negative effects. The aim was to categorize the biological age of men between 20 and 70 years of age and assess its relationship to their physical activity and fitness. Methods: Data included morphological variables, total body water, the results of five Eurofit motor tests and the percentage of maximum heart rate (HR%), during a cardiovascular test of more than 1,400 20–70 year-old men living in Kraków. Biological age was estimated with regression equations. Results: There were significant and consistent differences in physical fitness profiles between the three established groups of relations between biological and chronological age (biologically younger, equal, and older). These three categories of biological age were generally consistent with the regression analysis of physical fitness results, although declared physical activity seemed to be an independent factor. Conclusions: The selected morphological variables represent a set of characteristics useful for the determination of the biological age. The existing relationship between physical activity and biological age indicates that physical activity may contribute to the inhibition of involutional changes, even if it had only been performed regularly in the past.
