This study used an online survey to investigate the practices and perspectives of strength and conditioning coaches (SCCs) across different high-performance sports in China. The survey comprised of the following sections: (a) background information, (b) muscular strength and power, (c) speed, (d) endurance, (e) plyometrics, (f) flexibility, (g) physical testing, (h) technology use, and (i) programming. In total, 93 SCCs from 44 high-performance sports across 25 provinces/municipalities participated in this study (age 31.5 ± 6.9 yrs, experience as a SCC 5.5 ± 4.4 yrs). Periodization strategies were used by 97% of SCCs. Clean and derivatives (37%) were deemed the most important exercises for strength and power development. Heart rate (85%) and repetition maximum (72%) were the most used methods for determining set loads in endurance and strength training, respectively. Box drills (91%) were the most prescribed plyometric exercise and dynamic stretching (91%) was the most prescribed flexibility exercise. All SCCs physically tested their athletes and 95% frequently used technology-based equipment. For open-ended questions, 30% of SCCs would change their programs by improving monitoring, testing, equipment, and facilities. Thirty-nine percent of SCCs believed digitization and monitoring will be prominent future trends. The results indicated that most practices of SCCs in Chinese high-performance sports were dissimilar to those of SCCs in other countries. SCCs generally prescribe training according to the needs of sports. However, the interferences of many external factors also affected the scientific nature of training prescription.
To explore the effect of the PRECEDE-PROCEED model (the health professional's ability to apply theories of health behavior) in health education for young and middle-aged patients with lumbar disc herniation. Ninety patients with lumbar disc herniation admitted to our hospital from January 2020 to October 2022 were selected and divided into the control group (n=45) and the observation group (n=45) according to the random number table. The patients in the control group received routine Chinese medicine health education. The patients in the observation group received Chinese medicine health education in the PRECEDE-PROCEED model. The scores of chronic pain self-efficacy, compliance rate, visual analog scale score, and lumbar Japanese orthopedic association score of the two groups were compared. After nursing, the self-efficacy score of chronic pain in the observation group was better than that in the control group (p<0.05); the compliance rate of 95.56 % in the observation group was higher than that of 80 % in the control group (p<0.05); visual analog scale score of patients in the observation group was lower than that in the control group and Japanese orthopedic association score of lumbar vertebrae was higher than that in the control group (p<0.05). PRECEDE-PROCEED model can improve the compliance of young and middle-aged patients with lumbar disc herniation, reduce the occurrence of disease pain, and promote the treatment of lumbar disc herniation.
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.
