The study's objectives were to identify individuals LWBBC's needs for supportive care and to determine exercise program participation facilitators according to treatment type. A survey assessing the needs for supportive care and exercise facilitators was distributed on the Facebook pages of five non-profit Canadian cancer organizations for three months. Needs and facilitators were assessed according to the combination of treatment type received including chemotherapy, radiotherapy or a combination of both. A convenience sample of 214 women LWBBC (mean age 50 ± 11 years) responded to the survey. Most (84%) participants reported searching for supportive care, especially exercise or psychological support for pain/fatigue management and improvement of psychological well-being. Higer proportions of women receiving chemotherapy (86-95%) were searching for supportive care compared to women not receiving chemotherapy (70%). Psychological support was the most searched supportive care among women receiving both chemotherapy and radiotherapy, while exercise program was most sought out by women receiving only one of these two treatment types. Low cost (47%) and accessibility to a supervised program (46%) were the most important exercise program facilitators for participants during treatment. Needs of women LWBBC seemed to diverge according to received treatment and should be considered when tailoring supportive care for these individuals.","PeriodicalId":14171,"journal":{"name":"International journal of exercise science","volume":"18 5","pages":"276-289"},"PeriodicalIF":0.0,"publicationDate":"2025-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11881990/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143567107","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}

Sixty-three asymptomatic participants were recruited via convenience sampling. Nineteen participants did not meet the inclusion criteria, thus leaving 44 participants. Inclusion criteria included hamstring tightness defined using the passive knee extension test (PKE). Exclusion criteria included a history of any lower extremity injury, including hamstring injury, within the past 12 months. Participants were randomized into one of three groups: Nordic Hamstring Exercise (NHE) eccentric group, static hamstring stretching, or control group. Hamstring flexibility was assessed, via the PKE, at baseline, 3 weeks, and six weeks. Between and within group differences in hamstring flexibility were assessed using a mixed model ANOVA. The analysis yielded a significant time × group interaction ( < 0.05). At six weeks, both the static stretching and eccentric group had greater improvements in flexibility compared the control group (p < 0.001). This study adds to the body of research by demonstrating the positive effect of eccentric training on gross muscle length. It revealed the NHE results in similar increases in hamstring flexibility when compared to static hamstring stretching. As a result, either stretching or eccentric training can be used effectively to address hamstring flexibility deficits.","PeriodicalId":14171,"journal":{"name":"International journal of exercise science","volume":"18 8","pages":"263-274"},"PeriodicalIF":0.0,"publicationDate":"2025-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11881989/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143567110","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}

In addition, IMTP performance has been linked to jump performance. Recent research has shown that the pelvic belt (PEL) IMTP method produces higher absolute and relative peak force values than the Bar IMTP method. However, limited scientific data has examined the PEL IMTP method performance data and its relationship to dynamic strength and sports performance. The study aimed to provide a more robust comparison between the BAR and PEL IMTP methods and examine the relationship between these methods and several countermovement jump (CMJ) performance variables. Thirty healthy National Collegiate Athletic Association (NCAA) Division III athletes volunteered for this study. Each participant was asked to attend and complete four separate lab sessions utilizing a bilateral force platform. The results of this study demonstrated that peak force and relative peak force were significantly (p ≤ .05) greater during the PEL IMTP method than during the BAR IMTP method. Further, force development increased similarly in both the BAR and PEL IMTP methods, although there were no differences between the methods (p>.05). Lastly, Pearson's product-moment correlations demonstrated a medium and significant (p ≤ .05) relationship between CMJ and PEL IMTP variables. In conclusion, the PEL IMTP can measure lower body force performance capabilities. Further, PEL IMTP variables can be used to predict jump performance and, therefore, may be used for assessment and training purposes.","PeriodicalId":14171,"journal":{"name":"International journal of exercise science","volume":"18 3","pages":"226-238"},"PeriodicalIF":0.0,"publicationDate":"2025-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11881987/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143567075","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}

Sessions consisted of a warm-up, high-intensity soccer practice, followed by four soccer-specific skill tests. During the experimental sessions participants rinsed with a color-and-taste-matched CMR or placebo (PLA) solution before the skill tests. Thirst sensation (TS), rating of perceived exertion (RPE) and heart rate (HR) were assessed throughout sessions. Performance scores and HR values between sessions were compared with a one-way repeated measurements ANOVA. A Friedman test was used to compare RPE and TS. Post-hoc analyses were implemented when necessary. Agility times were significantly faster (p = .01) during CON session (10.9 ± 0.4 s) compared to PLA session (11.2 ± 0.4 s). There was no significant difference in scores for the other tests (p > .05). Post-practice RPE was lower (p = .01) for CMR session than CON session.

To test the hypothesis, that compared to a dynamic warm-up alone (DyWU), a dynamic warm-up with a multi-set sprinting potentiating stimulus (DyWU+SPR) would enhance discus throw performance. 12 NCAA Division I thrower athletes (18-25 year) randomly completed two sessions separated by at least 48 hours. One session involved a standardized dynamic warm-up (DyWU) and the other session involved a DyWU with multiple sets of a sprinting post-activation performance enhancement (PAPE) stimulus (DyWU+SPR), with both sessions followed by three trials of competition discus throws. A two-way ANOVA (warm-up x timepoint) with repeated measures was used for analyses, p < 0.05.

However, there is limited understanding of how differing body weight percentages influence gait and force production. This study aimed to investigate the relationship between force and gait parameters at different body weight percentages on a LBPPT. Twenty-seven healthy participants completed a series of walking, jogging, and running trials at three different body weight conditions: 100%, 90%, and 75%. Gait parameters, including cadence, stride length, stance time, and ground reaction force, were measured using the Digitsole Pro foot insoles and analyzed across the different conditions. Repeated measures ANOVA and pairwise comparisons were used to examine the effects of body weight percentage on the gait parameters. The results showed significant effects of BW on cadence, stride length, stance time, and impact force during running condition (p < 0.001). Jogging condition was significantly different across all % BW for all variables except ground reaction force (GRF). For walking, the only significant differences presented were for stride length on the right limb between 100% and 90% BW (p = 0.004) and 100% and 75% BW (p = 0.04) and time in stance on the left and right (p < 0.05). Pairwise comparisons revealed significant differences between the 100%, 90%, and 75% BW conditions for most gait parameters during jogging and running. These findings suggest that lower body weight percentages substantially influence gait mechanics and force production, especially as speed increases.","PeriodicalId":14171,"journal":{"name":"International journal of exercise science","volume":"18 7","pages":"239-250"},"PeriodicalIF":0.0,"publicationDate":"2025-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11881985/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143567109","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}

Thus, we aimed to evaluate the acute and chronic effects of strength training (ST) on urinary adiponectin, leptin, and resistin levels. Twelve untrained young men (23.42 ± 2.67 years) were included in this study. Body composition was evaluated at baseline and after completing of the training protocol using densitometry. Training protocol consisted of three exercises with three sets of 65% of one-repetition maximum (1MR) with a pause of 90 s between sets, each exercise lasting 5 s (2 s concentric / 3 s eccentric). The sessions were carried out three times a week for 10 weeks. Urine was collected during the pre- and post-training in the first and 30th session. Adipokine levels were determined by ELISA. Urinary levels of leptin acutely increased after the first ST session, and after the last ST session. Chronic changes in the leptin levels were also found when comparing the values before the last ST and before the first ST session. Urinary adiponectin levels changed in the comparison of values before and after the last session. There was a significant increase in the adiponectin levels when comparing values after the first and last ST sessions. The levels of resistin chronically increased.

The study employed a repeated-measures, parallel group design with 18 participants randomized into either a control group with fixed workouts or an experimental group with flexible workout selection based on perceived readiness. Participants were recreationally trained at baseline. Over a 16-week period, both groups completed assessments of strength and endurance, including deadlift, push-ups, and a two-mile run. The results indicated no significant difference in overall fitness improvements between the two groups, with both showing meaningful progress in strength and endurance measures. However, adherence rates were notably lower in the flexible group as the study progressed, potentially due to decision fatigue. Statistical significance was set at ρ ≤ 0.05, with main effects of time showing significant improvement in fitness scores across all groups. The findings suggest that while flexible programming offers similar benefits to traditional fixed programs, it may require strategies to maintain adherence over longer periods. Practical applications include the potential for flexible training to be used effectively in remote settings, particularly for populations like military personnel with varying access to fitness resources.","PeriodicalId":14171,"journal":{"name":"International journal of exercise science","volume":"18 8","pages":"43-55"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11798545/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143364600","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}
