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.

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.

The Carpathian Euroregion comprises the population of 5 countries, including Poland, Slovakia, Hungary and Romania - members of the European Union, as well as the Ukraine. Young women are statistically less involved in high-intensity physical activity than young men. The objective of this study was to assess the relationship between physical activity of young women aged 18-21 years and the BMI and conditioning factors. The study was conducted between 2010-2011 among 2,339 women. The Minnesota Leisure Time Physical Activity Questionnaire (MLTPAQ) was applied. It results from the study that 74.2% of young women are considered to have the proper BMI rate (18.5-24.9). As many as 16.2% are considered underweight and almost 10% have a higher BMI rate and are overweight. More than one third of respondents did not achieve the level of physical activity of 1,000 kcal/week, which is the minimum recommended amount of leisure physical activity time per week. In the case of women with low level of physical activity (<1,000 kcal), as many as 52% of the week activity is considered low-intensity activity EEPAlight. The character of changes of the BMI index with reference to the level of physical activity is very similar in women from towns/cities and women from villages. An increase of BMI along with the total physical activity was related to the increase of free fat mass FFM, despite of the level of physical activity. © Annals of Agricultural and Environmental Medicine 2014.

With the deepening of reform and opening up, all walks of life is running stable and orderly, but it lacks of emphasis on public sports, establish a set of completely public sports service comprehensive evaluation system is particularly important. The paper just along this direction, by establishing multilayer fuzzy evaluation method, applies mathematical statistics, analytic hierarchy process, questionnaire survey, component analysis and other methods to go deep into research, and refer to maximum membership corresponding principles. Research table concludes that a Chinese public sport service basically belongs to satisfied state, but it still has many problems that need us to constantly improve them. © 2014 Trade Science Inc. - INDIA.

With progress of times, Taekwondo has also been rapidly developing, and become formal event in Olympic Games. In order to find out Chinese athletes' shortcomings and defects, the paper analyzes mechanical relations and dynamical relations when athletes make roundhouse kicking; it gets athletes' potential energy generated when they make roundhouse kicking. And analyzes athletes data, it gets that when athletes make roundhouse kicking, their hip joint, knee joint and ankle joint kinematic features. Finally it gets that when athletes make roundhouse kicking, in case that quadriceps femoris and hamstrings fully contraction, they should try to reduce hip abduction angle and hip inflection angle as much as possible, shorten each phase completion time, improve motions' speed and motions surprise, so that arrives at anticipative effects and let own party get advantage. © 2014 Trade Science Inc. - INDIA.
