The purpose of this study was to measure body composition and athletic performance across a competitive season in collegiate volleyball players. Sixteen female NCAA Division III volleyball players (age- 19.9 ± 1.4 years, height- 1.7 ± 0.1 m, mass- 72.6 ± 10.5 kg) participated in the study. Data was collected during three weeks of the season: preseason (T1), midseason (T2), and postseason (T3). Body composition measurements via dual-energy X-ray absorptiometry (DXA), vertical jump height, hemoglobin, and subjective measurements of perceived athletic performance and energy levels (1-10 scale) were measured at each timepoint. Data was analyzed using one-way repeated measures analysis of variance. There were no significant differences between jump heights (p = 0.378), hemoglobin (p = 0.144), subjective performance (p = 0.472), or energy levels across the season (p > 0.329). DXA results revealed a significant increase in overall bone mineral density (BMD) (p < 0.001). Segmental analysis revealed that left leg BMD significantly increased (p = 0.037). Lean body mass significantly increased (p = 0.012) while fat mass significantly decreased (p < 0.001) from T1 to T3. The results suggest that repetitive jumping during practices and games can have favorable impacts on body composition. Coaches, sport scientists and nutritionists can use this information to optimize adaptations for VB players while improving performance and reducing the risk of injury during a competitive season.","PeriodicalId":14171,"journal":{"name":"International journal of exercise science","volume":"19 6","pages":"6003"},"PeriodicalIF":0.0,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13075565/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147722888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Linear mixed model analysis was employed to assess the changes caused by protocol, time, and limb dominance, and a repeated-measures correlation was used to assess the association between LFF and perceived fatigue or muscle soreness. Significant fatigue was induced by both protocols (p < 0.001), with LFF scores returning to baseline after 24 hours. Notably, following the fatigue protocols, a significantly lower LFF score was observed after the 4'TT compared to the 30'TT (d = 0.39, p = 0.032). Furthermore, a large and significant association between LFF scores and perceived fatigue (rmcorr = -0.5, p < 0.001) was identified, as well as a weak and significant association between LFF and perceived muscle soreness (rmcorr = -0.28, p < 0.001).

The effectiveness of caffeine in various circumstances, such as within a series of physiological assessments which utilize different energy systems, is less clear. The purpose of this research study was to determine the effectiveness of caffeine on different areas of the NFL combine-like tests, specifically the 40-yard dash (40-YD), standing broad jump (SBJ), and YMCA bench press test (YMCA-BP). Thirty-three healthy participants (19 men, 14 women: age 20.42 ± 1.23yrs) consumed a 200mg caffeine and placebo pill on two occasions. The participants were randomly assigned to which they received first and blinded to the caffeine or placebo. Forty-five minutes after taking the pill, participants performed the YMCA-BP (80lbs men, 35lbs women: 30 reps/min), the SBJ (3 attempts with best jump recorded), and ran the 40-YD (2 attempts, best recorded). Participants returned one week later, consumed the other pill, and performed the tests. Results from each trial were compared using a paired samples t-test. The results revealed no difference in YMCA-BP or SBJ. However, results were better with caffeine for the 40-YD (caffeine 5.69 ± 0.86; placebo 5.81 ± 0.89; p<0.001, mean difference = -0.118, 95% CI -0.109, -0.056, Cohen's d = 0.68).

However, from a practical standpoint, verbal swearing may not always be feasible in public settings. One potential alternative is the use of inner monologue swearing (i.e. verbalizing in one's mind), which could extend the utility of swearing to environments where vocalizing profanity is restricted. This study investigated whether inner monologue swearing enhances physical performance using a randomized crossover design. Forty-two physically active individuals were recruited for the study. Each participant completed two separate visits, spaced at least 72 hours apart to allow for recovery. During each visit, participants repeated, using inner monologue, either a swear word or neutral word every five seconds while completing three exercise tests in sequence: 1) grip strength, 2) wall sit time to exhaustion, and 3) plank time to exhaustion. Results indicate no significant difference in grip strength between swearing and neutral word conditions (p = 0.998). However, inner monologue swearing significantly improved wall sit (p = 0.008) and plank (p = 0.008) time to exhaustion compared to the neutral word using condition. These findings provide novel evidence that inner monologue swearing may enhance muscular endurance. However, the absence of a similar effect on grip strength suggests that this benefit may be task specific. These results have important practical implications, suggesting that inner monologue swearing may serve as a viable strategy to enhance physical performance in public settings where vocal swearing is not an option.","PeriodicalId":14171,"journal":{"name":"International journal of exercise science","volume":"19 5","pages":"5002"},"PeriodicalIF":0.0,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13075554/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147722913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examined the acute effects of mobile gaming session duration on heart rate (HR), stress, selective attention, and visual short-term memory (VSM) in male and female university students playing Realm of Valor (ROV), a popular multiplayer online battle arena game. Twenty recreational ROV players (10 males, 10 females; aged 20-22 years) completed a randomized crossover trial involving two remotely supervised gaming sessions: three games (~1 hour) and seven games (~3 hours), separated by a 7-day washout period. Participants played in consistent teams from their home environments. HR, stress (Suanprung Stress Test-20), selective attention (Stroop Color and Word Test), and VSM (CogniFit task) were assessed before and after each session using standardized, investigator-monitored protocols. HR increased significantly following both gaming sessions, with no difference between durations. Stress levels increased only after the seven-game session, with females exhibiting greater increases than males. Selective attention improved after three games but not after seven, with greater gains observed in the shorter session. VSM accuracy and response time did not differ significantly between gaming durations. These findings suggest that short-duration mobile gaming may enhance attentional performance with minimal stress, whereas prolonged play increases stress, particularly in females, and diminishes cognitive benefits.","PeriodicalId":14171,"journal":{"name":"International journal of exercise science","volume":"19 5","pages":"5003"},"PeriodicalIF":0.0,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13075561/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147722922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The primary aim of this study was to investigate the relationship between training load (TL), perceived cognitive workload, and sleep in varsity male volleyball athletes. The secondary aim was to understand the physiological and cognitive mechanisms leading to sleep disturbances following a match. Twelve varsity players on a men's university volleyball team were examined for 12 weeks of the competitive season. Sleep, internal TL and cognitive load were assessed using daily surveys. External TL was assessed using wearable jump monitors during training and matches. Participants filled the Pre-Sleep Arousal Scale to assess pre-sleep arousal and the Ottawa Mental Skills Assessment Tool to assess mental skills after eight matches. Our results show that the perceived cognitive load had a negative impact on total sleep time (p = 0.003) and sleep quality (p = 0.048). Moreover, internal TL had detrimental effects on sleep quality (p = 0.04). We also observed a negative association between cognitive pre-sleep arousal and sleep efficiency (p = 0.004). and sleep onset latency (p = 0.03). Finally, no effect was found between mental skills and post-match sleep. Our results suggest that assessing perceived cognitive workload is essential when monitoring student-athletes. Moreover, higher sleep onset latency and lower sleep efficiency were associated with elevated levels of cognitive arousal supporting the idea that post-match sleep difficulties are due to cognitive arousal rather than physiological arousal.","PeriodicalId":14171,"journal":{"name":"International journal of exercise science","volume":"19 5","pages":"5001"},"PeriodicalIF":0.0,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12965797/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147377485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thirty-six amateur soccer players aged 18-25 participated in a randomized controlled, assessor-blinded study. Participants sequentially performed a 5-minute standardized warm-up, group-specific acute bout (SS, DS, or NM), and a 5-minute cool-down. Pre- and post-test assessments consisted of the straight leg raise test (flexibility), Y balance test (balance), single-leg forward hop test (performance), T-test (agility), and BlazePod reaction time. All groups showed significant post-test improvements in flexibility, balance, and performance (all p < 0.05, η2 = 0.06-0.18). The NM group demonstrated a greater reduction in agility T-test time (p = 0.028, η2 = 0.10), while no significant agility changes were observed in the other groups (p > 0.05). Intergroup analysis revealed greater improvement in the anterior reach direction of the Y balance test for the NM group (p = 0.038, η2 = 0.19).

Fifty-one participants volunteered in this study. Group assignment was determined using the Cumberland Ankle Instability Tool (CAIT). Participants performed four tests in randomized order: the Y-Balance Test (YBT), the Athletic Single-Leg Stability Test (ASLST), the Time-in-Balance Test, and the Side Hop Test. Perceived stability was recorded after each test using the VAS. Participants with CAI had significantly worse ankle stability than those without CAI (p < .001). For the Time-in-Balance Test and the Side Hop Test, no significant difference was found in either physical tests or perceived stability. For the ASLST and the YBT, no difference was found in the physical performance. However, participants without CAI perceived significantly superior stability in both tests compared to those with CAI (p = .026 and .040, respectively). Correlation analysis showed that neither the physical scores nor the VAS had a strong correlation with the CAIT scores. Participants with CAI performed as well as those without CAI in the static balance test, dynamic balance test, and functional performance.
