The People's Republic of China obtained at the 2020 Tokyo Olympic Games its best historical performance in the triple jump, thereby winning the silver medal. The objective of this case study was to present how evidence-based knowledge was applied to improve selected factors that may have contributed to this result. The factors included running speed, strength, muscle power, jumping technique, body composition, mental preparation, training organization, and recovery. Short training blocks, monitoring of training sessions and athlete's status, individualized tapering, use of activation sessions the day before competition, and postactivation performance enhancement strategies used in training and at the event were concepts followed during the preparation to the Games. Improved performance in field tests and power training was accompanied by positive changes in approach speed, run-up accuracy, and jumping technique, which, together with mental preparation, enabled two personal records to be set in the Olympic final. The results in the field tests were among the best ever reported and could constitute a benchmark for world-class triple jumpers.

This study aimed to examine the relationship between physical activity and cancer patients’ survival beliefs and constructed a mediation model involving the mediating effects of interpersonal competence and quality of life. We conducted 252 questionnaire surveys on multiple chat groups for cancer patients using the WeChat software, and assessed physical activity, survival beliefs, interpersonal competence, and quality of life using standard scales. Data were analyzed using SPSS and AMOS. There were positive correlations between physical activity and quality of life (β = 0.393, p < 0.001), physical activity and interpersonal competence (β = 0.385, p < 0.001), interpersonal competence and quality of life (β = 0.455, p < 0.001), and quality of life and survival beliefs (β = 0.478, p < 0.001). In addition, a significant mediating effect between physical activity and survival beliefs was observed between interpersonal competence and quality of life (standardized indirect effect = 0.384, p < 0.001). The study revealed that effective physical activity led to higher interpersonal competence, more excellent quality of life, and improved survival beliefs in cancer patients, and that the association of physical activity with improved survival beliefs was fully mediated through interpersonal competence and quality of life. The findings suggest that the relevant government should increase policy support and publicity to improve cancer patients’ participation in physical activity.
