A086: The Mechanisms Of Mental Fatigue Among Table Tennis Athletes From The Perspective Of Positive Psychology, Jingyi Xie, Bin Wang

International Journal of Physical Activity and Health

Objective: In the realm of competitive sports, mental fatigue, as a prevalent negative psychological phenomenon, not only adversely affects athletes' immediate competitive performance, but also impedes their long-term career progression. This issue is particularly acute among table tennis athletes who endure persistent pressures and concerns. Presently, there is a burgeoning interest in investigating athletes' mental fatigue through the lens of positive psychological attributes. Notably, temperamental optimism fosters the development of positive cognitions and enhances psychological resilience. Similarly, cognitive reappraisal facilitates the augmentation of positive emotional experiences. Investigating the relationship between these variables and table tennis athletes' mental fatigue holds promise …

A098: Measuring Nudging: Can Nudges Promoting Physical Activity Among College Students?, Xinghua Wang, Hongbing Chen

International Journal of Physical Activity and Health

Background: The prevalence of physical inactivity poses a substantial public health challenge, as it is intricately linked to an elevated risk of adverse health outcomes. Within the context of college environments, students frequently face conditions that inadvertently foster inactive lifestyles. Nudges, defined as changes in the design of choice environments to help people make better choices predictably while maintaining freedom of choice, are frequently employed to promote health behaviors. Most nudge studies are based on only one or two types of interventions. However, the effectiveness of different types of nudges on improving physical activity on a large scale needs to …

A096: Analysis Of Knee Joint Load Characteristics In Different Angle Of Stride Movements In Table Tennis, Bei Zhang, Yanlong Zhang, Yanyu Yin, Minghui Wang

International Journal of Physical Activity and Health

Objectives: Stride is a typical type of footwork found in table tennis. During the game, athletes need to repeat stride movements at different angles according to the direction of the incoming ball, which makes the knee joint twist and flex, increases the burden on the knee joint, and increases the risk of knee injury. However, the effect of different angle stride movements on the load characteristics of athletes' knee joints is still unclear and needs further research. Therefore, this study used biomechanical research methods to explore the effects of 180° and 45° stride movements on the knee load characteristics of …

A106: Motivations For Grassroots Inheritance Of Intangible Cultural Heritage: The Case Of The Dh Yingge Team, Lu Liu

International Journal of Physical Activity and Health

Background: The protection movement for intangible cultural heritage is gradually becoming a global trend. However, the intangible heritage protection movements led by governmental organizations have been criticized for issues related to "authenticity" and "nationalism." Bottom-up inheritance and protection, or grassroots heritage preservation, refers to the process where intangible cultural heritage is continuously passed down within local communities and by the people themselves. Currently, there is limited research discussing intangible cultural heritage from the perspective of grassroots inheritance. This study selects collective action theory as the analytical framework and examined the motivations behind the formation of the Yingge team in DH …

A113: The Impact Of Motivational Climate On Class Engagement: Situational Interest And Self-Efficacy As Mediators, Chunli Zhong, Bo Shen

International Journal of Physical Activity and Health

Background/Purpose: An accomplishment within physical education classes involves actively involving students. Research underscores the importance of nurturing situational interest and self-efficacy to foster this engagement. Both self-determination theory and achievement goal theory propose that teachers can cultivate a supportive classroom environment, thereby boosting students' interest and confidence in their capabilities. Nevertheless, the transformable mechanism from motivational climate to actual class engagement needs further investigation. The purpose of this study was to examine the extent to which motivational climate variables (e.g., autonomy supportive climate, task-involving climate, and socially supportive climate) impacted student engagement via the mediative roles of situational interest and …

A119: Intermittent Hypoxic Training Promotes Whole-Body Hif-1Α Expression To Improve Exercise Capacity, Yuepeng Li, Lan Zheng

International Journal of Physical Activity and Health

Research Context: It has been shown that a hypoxic environment induces up-regulation of HIF-1α and changes in its downstream gene sequences, and that exercising under hypoxic conditions improves athletes' sprint performance. However, there is more controversy regarding the effects of exercise under hypoxic conditions on exercise capacity, and the molecular mechanisms have been less well studied. Therefore, the aim of this study was to investigate the link between HIF-1α expression and exercise capacity under hypoxic conditions of exercise, and to provide a realistic theoretical basis for intermittent hypoxic training to improve exercise capacity.

Research Methodology: A total of 480 wild-type …

A123: The Study Of Intervention Effect Of Promoting And Inhibiting Kinesio Tape On Patellofemoral Pain Syndrome, Ruyun Wang, Runzhe Wang, Zihan Yang, Yunhao Cui, Caixia Li, Xin Zhang, Shilun Hou

International Journal of Physical Activity and Health

Background/Purpose: The patellofemoral pain syndrome (PFPS), which might be caused by weakness and delayed activation of the vastus medialis obliquus (VMO), as well as tightness of the vastus lateralis (VL), gravely affects daily lives and exercises. Kinesio tape (KT) are often used to prevent and treat musculoskeletal diseases. Different application directions and tension levels can produce a promoting or inhibitory effect. If KT could improve the symptoms of PFPS through coordinating imbalanced muscles, it has positive significance. This study aimed to explore the effects of three KT application methods on PFPS and compare them with placebo, to explore possible psychological …

A126: High-Intensity Interval Training And Medium-Intensity Continuous May Affect Cognitive Function Through The Microbiota-Gut-Brain Axis, Mei Peng, Wenfeng Liu, Ruihan Zou, Yingzhe Tang, Xiangyuan Meng, Weijia Wu

International Journal of Physical Activity and Health

Background/Purpose: The gut-brain axis is the communication mechanism between the gut and the central nervous system, and the intestinal flora and lipopolysaccharide (LPS) play a crucial role in this mechanism. Exercise regulates the gut microbiota composition and metabolite (i.e., LPS) production. We aimed to investigate the effects of moderate-intensity continuous training and high-intensity interval training (HIIT) on cognitive function in C57BL/6J mice through gut-brain axis regulation of gut microbiota composition and LPS displacement.

Method: C57BL/6J male mice were randomly assigned into a quiet group (WTC), a high-intensity interval training group (WTH) and a moderate-intensity continuous training group (WTE). After 12 …

A135: Effects Of Exercise On Sleep Disorders In Women: A Systematic Review And Meta-Analysis, Yunheng Qiao, Chen Wang, Peizhen Zhang

International Journal of Physical Activity and Health

Objectives: Sleep disorders affect at least one-third of the population and are more common in women, with about 40 to 55% of pre- and post-menopausal women experiencing sleep disorders. Sleep disorders are also strongly associated with cardiovascular disease, making it imperative to improve them. Exercise has been reported to improve insomnia and reduce sleep latency and hypnosis medications. Current research indicates that the effects of exercise on sleep quality and insomnia are controversial. Therefore, we conducted a meta-analysis of randomized controlled trials (RCTs) to assess the effect of exercise on sleep quality in adult women.
