- Brief Summary
The primary aim of this study is to conduct a well-designed trial to investigate the effect of an MBI program entitled Mindfulness-based Peak Performance (MBPP) on endurance performance under pressure from an interdisciplinary approach of sport psychology, sports training, and cognitive neuroscience. The secondary aim is to examine the effect of MBPP program on performance-relevant mental attributes in behavioral and neurocognitive assessments.
The present study hypothesizes that the MBPP and self-talk groups will improve performance under pressure, but MBPP is expected to show greater improvement than ST. Additionally, we expect the MBPP will improve the relevant mental attributes.
- Detailed Description
Considering that increased competition levels are typically accompanied by elevated stress and anxiety, athletes' ability to cope with stress has gained even more importance in recent years. Growing evidence has demonstrated the effectiveness of mindfulness in reducing stress and enhancing athletic performance; however, its effectiveness remains a matter of debate and limitations due to absence of more rigorous designs, ecological validity, and randomized controlled trials.
Accordingly, the current trial, entitled Mindfulness-based Peak Performance (MBPP), will take an interdisciplinary approach (e.g., sport psychology, sports training, and cognitive neuroscience), to more definitively examine whether a tailored mindfulness-based intervention (MBI) affects athletic performance under pressure and relevant mental attributes.
Specifically, this study is an 8-week, three-arm, randomized controlled trial (RCT), and eligible participants will be randomly assigned into (1) an MBPP group (MBPP), (2) a self-talk group (ST), and (3) a wait-list control group (WC). The primary outcomes (e.g., endurance performance under pressure, performance-relevant mental attributes) and secondary outcomes (e.g., dispositional mindfulness, sports psychological skills) will be assessed before and after intervention.
The MBPP and ST are expected that will improve performance under pressure, but MBPP might show greater improvement than ST. Additionally, MBPP is expected that will improve performance-relevant mental attributes. The results from this trial might provide rigorous evidence and insight into MBI application in the sports context.

Group Intervention Description MBPP group MBPP The Mindfulness-based Peak Performance (MBPP) program consists of eight 60-min training sessions, once weekly for 8 weeks, which aim to enhance human performance. Self-talk group Self-talk The self-talk intervention serving as the active control group will be included in the current trial. In line with the MBPP intervention, the self-talk intervention is also designed to enhance athletic performance, and will consist of eight 60-min meaningful sessions, once per week for eight weeks.
- Primary Outcome Measures
Name Time Method Subjective stress responses 5 minutes for each assessment The participants' subjective perception of stress will be assessed via the Chinese version of the State-Trait Anxiety Inventory (C-STAI) (Wang and Chung, 2016) modified from the original version of STAI (Spielberger et al., 1971). The state subscale of the STAI will be the index of state anxiety influenced by pressure manipulation.
Executive function: Change in accuracy 30 minutes each at the Baseline-Assessment and at the Post-Assessment The executive function in terms of accuracy will also be assessed by the computerized Stroop Test. The types of trials are the three Chinese color words printed in one of the three types of color. Based on the combination of words and the pixels of the color, there are three types of trials: (1) congruent trials: the stimuli in which the color of the word corresponds to the semantic meaning of the word; (2) incongruent trials: the stimuli in which the paint color of the word is inconsistent with the semantic meaning of the word; and (3) neutral trials: the colored squared.
Change in attention 30 minutes each at the Baseline-Assessment and at the Post-Assessment The attention will be measured by event-related potential while Stroop Test.
Endocrine stress responses 1 minutes for each sampling Before and after pressure manipulation, and after endurance performance measure, stress responses of endocrine assessments will be assessed. Specifically, salivary cortisol (sCort) and salivary alpha-amylases (sAA) will be collected using the commercially available sampling devices.
Change in emotion regulation 10 minutes each at the Baseline-Assessment and at the Post-Assessment The Chinese version of the Difficulties in Emotion Regulation Scale (C-DERS) modified from DERS (Gratz and Roemer, 2004) will be used to assess emotional regulation. C-DERS is a 36-item self-reported questionnaire to measure the six facets of emotional regulation (i.e., awareness, clarity, impulse, goal, non-acceptance, and strategies). Items are rated on a 5-point Likert scale from 1 (almost never) to 5 (almost always).
Endurance performance: Change in time to exhaustion 30 minutes each at the Baseline-Assessment and at the Post-Assessment Time to exhaustion (TTE) will be one of the measured variables of endurance performance and be evaluated via a graded exercise test (GXT) on a motor-driven treadmill.
Endurance performance: Change in maximum oxygen consumption 30 minutes each at the Baseline-Assessment and at the Post-Assessment Maximum oxygen consumption (VO2max) will be one of the measured variables of endurance performance and be evaluated via a computerized indirect calorimetry system throughout the whole graded exercise test (GXT) on a motor-driven treadmill.
Change in brain resting state 8 minutes each at the Baseline-Assessment and at the Post-Assessment The frequency domain of electroencephalography (EEG) will also be recorded during the resting state at baseline and post-intervention.
Engagement 5 minutes at the Post-Assessment Participants' engagement will be an adherence score calculated by addition of the Z scores for overall participant attendance of MBPP/ST sessions and a Z score for overall participant minutes spent on home practice, then divided by the total Z scores. Researchers will record the attendance of each participant in MBPP or ST programs.
Executive function: Change in reaction time 30 minutes each at the Baseline-Assessment and at the Post-Assessment The executive function in terms of reaction time will be assessed by the computerized Stroop Test. The types of trials are the three Chinese color words printed in one of the three types of color. Based on the combination of words and the pixels of the color, there are three types of trials: (1) congruent trials: the stimuli in which the color of the word corresponds to the semantic meaning of the word; (2) incongruent trials: the stimuli in which the paint color of the word is inconsistent with the semantic meaning of the word; and (3) neutral trials: the colored squared.
- Secondary Outcome Measures
Name Time Method General dispositional mindfulness 5 minutes each at the Baseline-Assessment and at the Post-Assessment The general dispositional mindfulness will be assessed by Chinese version of the Mindful Attention Awareness Scale (C-MAAS)(Chang et al., 2011), which is modified from the original Mindful Attention Awareness Scale (MAAS; Brown \& Ryan, 2003). Higher scores reflect higher levels of general dispositional mindfulness.
Athletic dispositional mindfulness 5 minutes each at the Baseline-Assessment and at the Post-Assessment Athletic mindfulness will be measured by the Athlete Mindfulness Questionnaire (AMQ; Zhang et al., 2017). Higher scores reflect higher levels of athletic dispositional mindfulness.
Athletic psychological skills 5 minutes each at the Baseline-Assessment and at the Post-Assessment Athletic psychological skill levels will be assessed using the Athletic Psychological Skill Inventory (APSI) (Chiou and Chi, 2001), which is a modified Chinese version of Athletic Coping Skills Inventory-28 (ACSI-28; Smith et al., 1995).
