José A. Páez-Maldonado, Claro Cano, Pedro J. Cornejo-Daza, Juan Sánchez-Valdepeñas, Luis Rodiles-Guerrero, Mathias Wernbom, Manuel Ortega-Becerra, and Fernando Pareja-Blanco
Purpose: To investigate the effects of 3 training volumes in the bench-press exercise performed with interrepetition rest periods, matched for fatigue, on strength gains and neuromuscular adaptations. Methods: Forty-three resistance-trained men were randomized into 3 groups: low (LOW), moderate (MOD), and high (HIG) volume. The intensities increased from 70% to 85% of 1-repetition maximum (1RM) over the 8-week training period. Each session consisted of only 1 set with short interrepetition rest periods. LOW performed only 3 repetitions per session (8-wk total: 48 repetitions); MOD completed 15, 12, 10, and 8 repetitions per session with 70%, 75%, 80%, and 85% 1RM, respectively (8-wk total: 180); and HIG performed 24, 21, 18, and 15 repetitions per session with 70%, 75%, 80%, and 85% 1RM, respectively (8-wk total: 312). Progressive loading and fatigue tests were conducted in the bench-press exercise before and after the training period. Electromyography (EMG) signals from the triceps brachii were registered during these tests. Results: HIG and MOD showed higher velocity loss than LOW (16% vs 12%). No significant group × time interaction was observed for any variable. All groups improved significantly in all strength-related variables, except for maximal unloaded velocity, where only MOD obtained significant gains. Only LOW and MOD induced significant improvements in EMG. MOD obtained the greatest effect sizes in almost all strength variables. Conclusions: No significant differences were found in the performance gains obtained by each group despite the wide differences in the total volume accumulated by each group.
Motivational Predictors of Schoolchildren’s Moods in a Recess Intervention
Antonio Méndez-Giménez and Iván García-Rodríguez
Recess provides an opportunity to promote physical activity among schoolchildren. There is limited research on the effects of specific recess interventions, such as moveable equipment, physical structures, or painting playground, on motivational and affective-emotional variables. The study investigated the impact of a recess intervention based on children’s play using their own self-made materials. The researchers examined how this intervention affected basic psychological needs (including novelty), motivational regulations, self-determination index (SDI), and mood states, such as fear, happiness, sadness, and anger in 219 schoolchildren from third to sixth grade. The multivariate analysis of variance and univariate analyses found a decrease in identified, introjected, and external regulations, amotivation, and fear and an increase in SDI by grade. Boys scored higher on autonomy, competence, external regulation, and anger while girls scored higher on happiness. SDI and novelty were predictors of happiness in boys while relatedness was the main predictor for girls. Relatedness negatively predicted anger in boys. SDI negatively predicted fear and sadness in both genders. These findings suggest that recess interventions should consider motivational and emotional differences by grade and gender to promote physical activity and well-being in schoolchildren.
The Relationship Between Cold-Water-Immersion Activities, Mental Health, Self-Efficacy, Resilience, and Mental Toughness
Annmarie Mullooly and Dylan Colbert
While a breadth of literature has asserted the potential physiological benefits of cold-water-immersion (CWI) activities (such as sea swimming, ice baths, and cold showers), analyses on their possible psychological effects is more limited. The current analysis (N = 164) aimed to explore the relationship between CWI and a number of psychological variables pertaining to mental health and psychological fortitude by comparing those who engage in CWI via various modalities (n = 120) and at various levels of frequency to those who do not (n = 44). When controlling for levels of daily stress, engagement in cold-water activities was found to be associated with lower levels of depression, anxiety, and stress, as well as higher levels of resilience, self-efficacy, and mental toughness. Furthermore, analyses suggested a “dosage effect” as more frequent CWI was associated with significantly more positive levels of mental toughness and self-efficacy.
A Second-Generation Mindfulness-Based Intervention Focusing on Flow State: A Samatha-Based Training
Daliang Zhao
Currently, there is no empirical research on second-generation mindfulness training in the field of sport psychology. This study designed Samatha-based training (SBT) according to the principles of Samatha (a Buddhist practice) and preliminarily tested its influence on flow state. A total of 22 martial-arts-routine athletes were divided into two groups: the SBT group (n = 10) and the wait-list group (n = 12). The 7-week intervention demonstrated that SBT significantly enhanced the scores in present-moment attention, awareness, and flow state. These results support the effectiveness of SBT as a novel second-generation mindfulness-based intervention. Furthermore, the concept of mindfulness is discussed from the Samatha perspective, and subsequently, the reason that SBT promotes flow state was explored from a new perspective.
Transitioning From Traditional Sport to Esport: Exploring Sport Psychology Practitioners’ Experiences
Jonathan Brain, Alessandro Quartiroli, and Christopher R.D. Wagstaff
Sport psychology practitioners are increasingly operating in the esport domain. Yet it remains unclear how practitioners who have exclusively been trained in traditional sport develop a contextually grounded understanding of their practice in esport. This study, framed from an ontological relativism and epistemological interpretivism approach, involved semistructured interviews with 10 qualified practitioners (three female, seven male) who transitioned from traditional sport to esport. Data were analyzed using reflexive thematic analysis and presented via three composite vignettes: (a) My wish was to feel a part of the team, but there’s no team; (b) To be honest, did I have assumptions going into esport? Absolutely!; and (c) Esport is the wild, wild west. Our findings offer insights on the hurdles associated with transitioning from traditional sport to esport, thus highlighting the important role that esport organizations, training routes, and educational institutions have in supporting practitioners to ethically and effectively work in this domain.
Watching Exercise and Fitness Videos on TikTok for Physical Education: Motivation, Engagement, and Message Sensation Value
Manuel B. Garcia
Purpose: This study aimed to examine how physical education (PE) students engage with fitness content on TikTok. Methods: The evaluation involved 597 students enrolled in a PE 1 course across three campuses of a prominent university. Results: Findings show that students primarily watch TikTok videos for entertainment, with male students also seeking motivation and social interaction, while female students look for escape, advice, and guidance. Engagement is highest for videos featuring body transformations, fitness tips, and motivational content, with a tendency to apply learned exercises, tips, and nutrition education. Body transformations and motivational videos effectively arouse emotions and elicit affective responses. Conclusion: This research highlights diverse motivations and impacts of fitness content on TikTok among PE students, contributing to the literature on social media usage and offering insights for enhancing instructional practices in PE and understanding digital media interaction.
Body Mass Management Practices of Olympic Weightlifting Athletes
Amie M. Cox, Carl Langan-Evans, David Jenkins, Reid Reale, Fiona Pelly, and Gary J. Slater
This study explored the body mass (BM) management practices among competitive male and female Olympic weightlifting athletes, hypothesizing that athletes compete in lighter weight categories than their habitual training weight (i.e., making weight). Utilizing a validated, anonymous survey, data were collected from 149 Olympic weightlifting athletes (>18 years; female = 94). The survey comprised five sections: demographics, training/competition history, weight history, source of influence, and BM management practices. The prevalence, magnitude, and methods employed for BM management were analyzed with subgroup analysis using one-way analysis of variance. Post hoc testing including Spearman’s rho and chi-square analysis was completed when a significant effect was found. Three quarters (76%) of athletes acknowledged using chronic weight loss and/or acute weight loss strategies to make weight. Usual BM loss (2%–3%) in the week before competition was within recommended guidelines. Gradual dieting, fluid restriction, and low food weight, high-calorie options were the most commonly used BM management strategies. Female athletes were more likely to use gradual dieting (p = .043; r = .104) and were less likely to increase their exercise (p = .046; r = −.105) and utilize fasting (p = .038; r = .05) compared with their male counterparts. Women further identified dietitians/nutritionists (p = .006; r = .022) as a highly influential source of information. This research offers new insights into the BM management practices of Olympic weightlifting athletes, identifying that the majority of athletes compete at a BM lighter than their habitual training weight, achieved using a range of chronic weight loss and acute weight loss strategies.
Factors Informing Training Load During the Transition From Club to National Football Teams
Joshua J Gould, Ewan Clements, Fabian Ehrmann, and Rob Duffield
Purpose: This study examined the relationship of precamp match exposure, travel demands, perceptual wellness, and musculoskeletal screening with ensuing training load (TL) during national-team (NT) duties for international footballers (soccer). Methods: Match minutes and days since last match prior to NT arrival were collected for match exposure. Travel duration and time-zone difference were included as travel demands. Perceptual fatigue, soreness, sleep quality, and stress scores were collected via self-report questionnaire on arrival to NT. Musculoskeletal testing on day 1 of NT included knee to wall and hip internal and external rotation. Relative TL across the first 3 days of NT camp was measured via total distance, high-speed running distance, very high-speed running distance, and accelerations and decelerations per minute. Linear mixed models determined the influence of independent variables on respective TL metrics, with the player included as a random effect. Results: Total distance, high-speed running, very high-speed running, and decelerations per minute were all highest on day 3 (P < .001). Small relationships existed (R 2 < .15) between decreased total distance per minute and increased soreness (P = .037), while decreased high-speed running per minute was associated with increased fatigue (P = .017). Small associations existed between decreased accelerations per minute, increased hip internal rotation (P < .001), fatigue (P = .033), and knee to wall (P = .016), while decreased decelerations per minute were associated with increased soreness (P = .001), knee to wall (P = .024), and days between recent match and arrival (P = .003). Conclusions: Very small relationships existed between fatigue, soreness, musculoskeletal screening, and prior match exposure with TL. The larger influence of camp day suggests that deliberate periodization of training is a major factor for prescription on arrival into NT duties.
