ABSTRACT Introduction: This is a study on the reasonable organization and collocation of sports health elements in different sports forms, and how this is reflected through scientific exercise instructors. Objective: To improve the effect of sports medicine on the biomechanical energy metabolism of human health. Methods: The biomechanical model of knee joint stress was used to analyze the mechanical behavior of knee joint flexion, such as movement and contact; the variation law and peak value of stress on the contact surface of the tibiofemoral joint were obtained. Results: Based on the changes of stress on tibiofemoral joint contact surface and the peak value of the data obtained in this paper, the model and data basis were provided for guiding scientific sports training and sports medicine treatment, preventing knee joint sports injury, knee joint inflammation, and reasonably improving sports performance. Conclusions: Sports medicine is effective in improving human health. The objects of clinical exercise guidance include all people, from infancy to the old age. The function of exercise is recognized in the effect of the whole process of prevention, treatment and rehabilitation of a variety of clinical diseases. The effectiveness of exercise in the whole process of disease is also recognized. Level of evidence II; Therapeutic studies - investigation of treatment results.

Sulfur Containing

Hydrogen sulfide (H2S) is one of the main pollutants in the atmosphere, which is a serious threat to human health. The decomposition of sulfur-containing organics in chicken houses could produce a large amount of H2S, thereby damaging poultry health. In this study, one-day-old broilers were selected and exposed to 4 or 20 ppm of H2S gas (0-3 weeks: 4±0.5 ppm, 4-6 weeks: 20±0.5 ppm). The spleen samples were collected immediately after the chickens were euthanized at 2, 4, and 6 weeks. The histopathological and ultrastructural observations showed obvious necrosis characteristics of H2S-exposed spleens. H2S exposure suppressed GSH, CAT, T-AOC, and SOD activities; increased NO, H2O2, and MDA content and iNOS activity; and induced oxidative stress. ATPase activities and the expressions of energy metabolism-related genes were significantly decreased. Also, the expressions of related necroptosis (RIPK1, RIPK3, MLKL, TAK1, TAB2, and TAB3) were significantly increased, and the MAPK pathway was activated. Besides, H2S exposure activated the NF-κB classical pathway and induced TNF-α and IL-1β release. Taken together, we conclude that H2S exposure induces oxidative stress and energy metabolism dysfunction; evokes necroptosis; activates the MAPK pathway, eventually triggering the NF-κB pathway; and promotes inflammatory response in chicken spleens.

Temperature And Humidity

In this study, a series of references on human physiology and psychology response to hot and humid environments were analyzed. On basis of the thermo metabolism system, energy metabolism system, cardiovascular system and respiratory system, impact mechanism of high temperature and humidity on human health was presented. The results indicate that the high temperature and humidity in working environment have significant impact on human health. The high temperature and humidity cause the reducing of temperature difference in vitro and in vivo, the difficult of metabolic heat diffusion, the significant increasing of energy metabolism and oxygen consumption, heart failure, hypoxia and other physiological responses.
