RESUMO

Numerous bodily processes deteriorate with age, chief among them being the loss of muscle mass and function. The condition referred to as aging myasthenia gravis impairs older persons' quality of life and is linked to a higher risk of several chronic illnesses. An increasing number of studies conducted in the last several years has demonstrated that moderate exercise can halt this process. Specifically, by promoting autophagy, aerobic exercise helps to postpone the onset of senile myasthenia gravis. In this work, we will explore how aerobic exercise modulates autophagy to prevent muscle aging and examine the most recent findings in this area of study. We discovered that exercise-induced autophagy can effectively balance protein degradation and relieve skeletal muscle atrophy by looking through pertinent literature. Aerobic exercise has a direct impact on autophagy, but it can also delay the onset of senile myasthenia gravis by enhancing blood flow, lowering inflammation, and boosting muscle oxidative capacity. In order to postpone the onset of senile myasthenia gravis, research on the mechanism of action of aerobic exercise in inducing autophagy will be discussed in detail in this study.

RESUMO

Athletes can also cause damage to some parts of their body during training, so specialized preparation activities should be carried out before athlete training to reduce the damage caused to the athlete's body, allowing the stressed parts to move and distribute the load. Excessive recovery has a significant effect on improving the performance level of the athletes studied and preventing sports injuries. This article studies the data analysis of body recovery and injury prevention in physical education teaching based on wearable devices. Real time collection of students' exercise data, including indicators such as exercise volume, heart rate, steps, distance, etc., by wearing wearable devices. By using Internet of Things technology to transmit data to cloud servers, data analysis and mining techniques are used to process the data and study issues related to body recovery and injury prevention. Specifically, this article adopts methods such as time series analysis, machine learning algorithms, and artificial neural networks to analyze the relationship between exercise data and body recovery and injury prevention, providing scientific guidance and support for physical education teaching. This method can monitor students' exercise data in real-time, predict the risk of physical recovery and injury, and provide corresponding prevention and guidance suggestions.

RESUMO

ABSTRACT Introduction: Contemporary table tennis teaching lacks attention to global abilities; some studies suggest that functional training can supply the demands of the high level of sport competition. Objective: Study the effect of functional training on teaching table tennis to college students. Methods: A controlled random selection was carried out (n=40), in which the experimental group (n=20) chose a functional training program. In contrast, the control group (n=20) participated in the teaching of traditional table tennis skills. The training frequency was one hour daily, three times a week, lasting six weeks. Table tennis-specific fitness was assessed before and after the experiment. Data were cataloged and statistically analyzed. Results: On the manual skills index, the experimental group's score increased from 63,194 to 79,683 points after the experiment, and the control group's score increased from 64,788 to 68,775 points after the experiment. In the regression index, the experimental group score increased from 63.645 to 78.614, and the control group score increased from 64.152 to 70.574. Conclusion: The functional training mode proposed in this paper can rapidly improve the competitive level of table tennis and improve the competitive performance of its practitioners. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

RESUMO

To improve the stabilities of low methoxy pectin (LMP) stabilized O/W emulsions for the delivery of bioactive substances, LMP was firstly modified with soy peptide (SP), corn peptide (CP) and whey protein peptide (WPP), respectively, by using dry-heat method, then the properties of LMP-peptide complexes stabilized O/W emulsions were characterized and the in vitro digestion of emulsions with ß-carotene was test to evaluate the potential applications. LMP-peptide complexes were formed by covalent bonds according to FT-IR spectroscopy. Compared to LMP stabilized emulsions, LMP-peptide complexes stabilized emulsions had smaller droplet sizes and higher stabilities in the changed pH value, temperature and ionic strength. Based on the results of in vitro digestion tests, LMP-SP and LMP-WPP obtained by incubating LMP with peptides at 60 °C for 12 h at the weight ratio of 4:1 were more suitable for the preparation of O/W emulsions to deliver camellia oil and ß-carotene.

RESUMO

An increased fracture risk is often observed in cancer patients undergoing radiotherapy (RT), particularly at sites within the field of radiation. Therefore, the development of appropriate therapeutic options to prevent RT-induced bone loss is urgently needed. A soluble form of the BMP receptor type 1A fusion protein (mBMPR1A-mFc) serves as an antagonist to endogenous BMPR1A. Previous studies have shown that mBMPR1A-mFc treatment increases bone mass in both ovary-intact and ovariectomized via promoting osteoblastic bone formation and inhibiting osteoclastic bone resorption. The present study was designed to investigate whether mBMPR1A-mFc administration prevents radiation-induced bone deterioration in mice. We constructed an animal model of radiation-induced osteoporosis by exposure to a 2-Gy dose of X-rays. Micro-CT, histomorphometric, bone-turnover, and mechanical analyses showed that mBMPR1A-mFc administration prevented trabecular microarchitecture deterioration after RT because of a marked increase in bone formation and a decrease in bone resorption. Mechanistic studies indicated that mBMPR1A-mFc administration promoted osteoblastogenesis by activating Wnt/Lrp5/ß-catenin signaling while decreasing osteoclastogenesis by inhibiting the RANKL/RANK/OPG pathway. Our novel findings provide solid evidence for the application of mBMPR1A-mFc as a therapeutic treatment for radiation-induced osteoporosis.
