Reasonable amount of exercise is the premise of physical education teaching. On this premise, in the process of students’ physical education teaching, the appropriate degree of actual exercise amount will affect the effect of motor skill learning and physical exercise to a great extent. Through monitoring the amount of exercise and then evaluating the quality of physical education teaching is the focus of the implementation of physical education. Looking for simple and effective monitoring equipment has important practical significance. In this paper, through the analysis of the current situation of wearable sensor in the development of physical education teaching, put forward the effect monitoring of sports curriculum based on wearable sensor in intelligent environment. In this paper, 258 freshmen and sophomores who use wearable devices are selected for monitoring and analyzing, and the pertinence, accuracy and data of wearable sensor physical education course and traditional physical education course are compared and analyzed, and the results are discussed and analyzed. It is concluded that wearable sensor can promote physical education curriculum, not only can improve the teaching pertinence, strengthen the accuracy, but also can In order to improve the scientificity of physical education curriculum effect monitoring. The research in this paper has important practical significance for monitoring the effect of wearable sensors in physical education curriculum.
Objective Environmental and maternal exercise experienced even during the very earliest stages of life has the potential to cause developmental changes.The growing evidence demonstrated that diverse environmental stressors affect offspring in variousaspects in early stage of lifeand can be transmitted directly or indirectly by both parental lines.The purpose of the present study was to investigate the effect of across generations maternal exercise training under the hypoxic environment on mitochondrial biogenesis and angiogenesis related protein expressions of skeletal muscle in offspring ofmultiple generations.
Methods The experimental groups were divided into four groups as NCON (control in normoxia), NEXE (exercise in normoxia), HCON (control under hypoxia), HEXE (exercise under hypoxia), and studied for three generations. Exercise groups were run on animal treadmill at 60%-75% VO2maxfor one hour per day, five times per week for 10 weeks (seven weeks before conception and during conception for three weeks). Animals were sacrificed at a given time table and assayed mitochondrial biogenesis and angiogenesis related protein expressions using western blotting.
Results The major findings from the present study were firstly, maternal exercise training before and during conception under hypoxic environment increase in mitochondrial biogenesis and angiogenesis related proteins expressions in both maternal and offspring skeletal muscles, secondly, long term of exposure to hypoxic environment without exercise training increase in mitochondrial biogenesis and angiogenesis related proteins expressions in offspring skeletal muscles, and further increased when exercise training performed at hypoxic environment, lastly, there was no cumulative benefit by consecutively exposure for three generations under hypoxic environment, which is indicating world winning runners from high altitude dwellers may not relay on the duration of sojourn under hypoxic environment, but rather selection and training related factors.
Conclusions In summary, maternal exercise training before and during conception under hypoxic environment increase in mitochondrial biogenesis(PGC-1α, COX-Ⅳ, NRF-1, mtTFA) and angiogenesis(HIF-1α, VEGFtotal) related proteins expressions in both maternal and offspring skeletal muscles, especially exercise training stimulated the protein expressions under hypoxic environment than normoxic condition. Therefore, exercise capacity may be endowed by both hypoxic environment and exercise training at hypoxic environment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
