This study aimed to examine if female collegiate soccer players exhibited worse ankle stability and single-leg balance than female non-soccer players, and whether there was a correlation between ankle stability and single-leg balance. Eighteen female collegiate soccer players and 22 female non-soccer players participated in the study. The Cumberland Ankle Instability Tool (CAIT) was used to evaluate ankle stability. The Athletic Single Leg Stability Test (ASLST) of the Biodex Balance System was used to examine static single-leg balance, and the Y-Balance Test (YBT) was used to examine dynamic single-leg balance. Results show that 55.56% of soccer players and 9.09% of non-soccer players exhibited chronic ankle instability. The CAIT score of soccer players was significantly lower than non-soccer players (p = .031). There were no significant differences between the two groups in the ASLST and the YBT. Very low correlations were found between the CAIT score and any static or dynamic balance measures (r < .094). Female soccer players who exhibited worsened ankle stability did not exhibit compromised static or dynamic single-leg balance. Future studies should examine if soccer players have established better motor control of single-leg standing through years of training to compensate for worse ankle stability. In addition, the CAIT score alone might not accurately represent static or dynamic balance control in female collegiate soccer players.","PeriodicalId":14171,"journal":{"name":"International journal of exercise science","volume":"17 6","pages":"1406-1415"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11728582/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142978603","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}

Since fatigue can manifest itself in multiple ways, its influence is difficult to understand, and many authors propose different studies with the aim of obtaining firm conclusions. Thus, the aim of this systematic review was to analyze the effect of fatigue on the modification of biomechanical parameters to mitigate adverse effects and optimize positive adaptations to training. A systematic review was carried out using scientific research papers from specific sport science databases in advanced search dated 02/2023. This systematic review was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Eligibility criteria were established according to the PICO (Participants, Intervention, Comparison, Outcome) strategy. The PEDro scale was used to evaluate the methodological quality of the publications. Twelve papers were analyzed, with a median PEDro score of 8.0, including 375 participants. The main results show that fatigue affects biomechanical parameters in endurance running, especially untrained athletes. Fatigue affects the biomechanical parameters of running and consequently triggers a decrease in sports performance. There is controversy among authors on the modification of some biomechanical parameters. The proposal of new measurement sensors can be a success to monitor the evolution of fatigue. The dominant mechanism for the perception of fatigue is neuromuscular fatigue. There are differences between trained and untrained runners.","PeriodicalId":14171,"journal":{"name":"International journal of exercise science","volume":"17 1","pages":"1377-1391"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11728577/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142978587","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}

Repeated sprints with (RCOD) and without (RSA) change-of-direction has therefore been recognized as an important fitness component. The purpose of the present study was to examine the differences in physiological responses between RSA and RCOD, and the relationship with Yo-Yo intermittent recovery test (YYIR1), as an estimate of aerobic capacity, in female soccer players. Thirteen female soccer players (age: 20.8 ± 2.6 years) participated. All players performed an RSA and RCOD test, as well as a YYIR1 test. Total time, fatigue (dec%), lactate ([La]b), rating of perceived exertion (RPE) and heart rate were recorded for each sprint test along with total distance covered in the YYIR1. RSA induced significant higher dec% (8.0 ± 3.0% vs. 5.0 ± 2.4%, p = 0.008, ES = 0.89), [La]b (13.5 ± 3.1mml/L vs. 9.9 ± 3.0mml/L, p = <0.001, ES = 2,25) and RPE (8 vs. 7, p = 0.003, ES = 1.0) compared to RCOD. The heart rate recovery was significantly faster for RCOD compared to RSA (173 ± 11 bpm vs. 178 ± 8 bpm, p = 0.02, ES = 0.89). No significant correlation could be found between aerobic capacity and RSA and RCOD variables. RSA was a more physiological taxing test compared to RCOD when the protocols were matched for sprint duration. This information can help athletes and coaches that are involved in women's soccer to design and adapt training strategies in the future.","PeriodicalId":14171,"journal":{"name":"International journal of exercise science","volume":"17 6","pages":"1605-1617"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11728590/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142978604","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 literature search was conducted through Cochrane Library, Embase, PubMed, Web of Science. Cohen's effect size (ES) and 95% confidence intervals (CIs) were computed using a random effects model. While comparing males and females, as well as pre-puberty and puberty stages, we conducted subgroup analyses for pre-puberty versus puberty and for males versus females respectively. Thirteen studies published between 2003 and 2021 were included in the analysis. In the pre-puberty stage, no statistical difference was observed on knee extensors or flexors between male athletes and female athletes (p=0.695, 0.138); In the puberty stage, males exhibited higher strength relative to weight compared to females for both knee extensors and flexors (SMD=1.36, 1.25). From pre-puberty to puberty, the strength of knee extensors and flexors relative to weight vastly increased for males (SMD=-1.71, -1.86), while no significant change was found for females (p=0.436, 0.071). There were no discernible sex- or age-related differences in the hamstring-quadricep (HQ) ratio (p=0.590, 0.834). The validity of the HQ ratio as a parameter for predicting injury risks was brought into question by the findings of this study. Strength of male athletes started to grow in puberty while the increase in strength for female athletes was not significant, which indicated that more sex-specific training and injury reduction program should be accomplished.","PeriodicalId":14171,"journal":{"name":"International journal of exercise science","volume":"17 6","pages":"1461-1477"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11728586/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142977746","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}

Low balance confidence and other factors related to the physical and psychosocial adaptation to amputation could contribute to why people with TTA actively avoid PA. Studies have investigated lower extremity amputations and barriers to PA in general, but none have focused solely on transtibial amputation and its relationship with PA participation and avoidance habits. To address this issue, 21 participants with TTA (14 male, 6 female, and 1 non-binary) shared their experiences through an online survey. Relationships between variables were examined with Spearman and Pearson correlations. Results revealed a positive relationship, with a moderate effect size between balance confidence and the sport index scale and multiple other correlations between the physical and psychosocial adaptation to TTA and PA participation and avoidance. Those who participate in sport following TTA seem to show a positive association with social adjustment and balance confidence. In addition, adaptations such as adjusting to new limitations and activity restrictions, as well as satisfaction with the function of the prosthesis, are also related to PA participation and avoidance. This study supports the premise that participating in PA, specifically sport, has physical and psychosocial benefits that cannot be undervalued. Insights drawn from this study lend support to evidence-based practices of rehabilitation programs for people with TTA that focus on balance confidence training. If those with TTA are interested in sports, balance confidence training via sport-specific training could further facilitate a positive adaptation following TTA.","PeriodicalId":14171,"journal":{"name":"International journal of exercise science","volume":"17 5","pages":"1663-1678"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11728572/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142978601","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}

Nevertheless, a considerable proportion of officers still fail to engage in any LTPA. There is a clear need to identify correlates of physical activity among this specific occupational group to help the design of workplace physical activity interventions. Rooted in the self-determination theory, this study seeks to assess the LTPA level of police cadets and examine its relationship with the different regulatory forms of motivation. In this cross-sectional study, 188 police cadets completed a survey assessing their LTPA level and motivational regulation for physical activity. On average, police cadets reported 395 ± 192 minutes/week of physical activity. Only 12 participants (6.4%) reported physical activity levels lower than the usually recommended minimum levels of 150 minutes/week. Overall, autonomous forms of regulation were by far the most endorsed by police cadets. Finally, LTPA was positively associated with intrinsic regulation (rs = 0.46), identified regulation (rs = 0.30), and introjected regulation (rs = 0.20). To our knowledge, this study is the first to use a theoretical framework to assess the relationship between LTPA and motivation in police cadets. Our results suggest that police cadets are highly active and mainly driven to engage in LTPA through autonomous motivations. The present study highlights the importance of fostering autonomous regulation for physical activity throughout the training of cadets.","PeriodicalId":14171,"journal":{"name":"International journal of exercise science","volume":"17 5","pages":"1504-1516"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11728584/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142978505","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}

Children with high levels of social support are more likely to achieve adequate levels of PA. The purposes of this pilot study were to examine the impact of an after-school intervention on perceived peer and parental support among adolescent girls and to identify correlates of support to explore in future studies to increase PA. Seventeen low-active girls in 6th-7th grade were recruited from a local middle school to participate in an 8- week intervention where they were exposed to various types of PA and discussed PA topics with their peers and college-aged mentors. Peer and parental support, self-reported physical activity, moderate-to-vigorous physical activity, and physical literacy self-evaluation were measured before and after the 8-week intervention. Paired samples t-tests indicated that parental support increased from pre- to post-intervention (t = 4.4, p < .001, d = 1.2, 95% CI = 1.7, 5.18), whereas there was a small, non-statistically significant increase in peer support (t = 1.5, p = 0.15, d = .4, 95% C I = -.89, 5.04). Correlations for the variables at pre-intervention indicated that there were significant correlations between peer and parental support (r = 0.74, p = 0.004), whereas at post-intervention there were significant correlations between peer and parental support (r = 0.83, p < .001), and physical literacy with peer support (r = 0.70, p = 0.008) and parental support (r = 0.69, p = 0.009).

This study assessed the comparability and applicability of VB systems in obtaining snatch kinematics by comparing the outcomes to an MB reference system. 21 weightlifters (15 Male, 6 Female) performed 2-3 snatches at 65%, 75%, and 80% of their one-repetition maximum. Snatch kinematics were analyzed using an MB (Vicon Nexus) and VB (Contemplas along with Theia3D) system. Analysis of 131 trials revealed that corresponding lower limb joint center positions of the systems on average differed by 4.7 ± 1.2 cm, and upper limb joint centers by 5.7 ± 1.5 cm. VB and MB lower limb joint angles showed highest agreement in the frontal plane (root mean square difference (RMSD): 11.2 ± 5.9°), followed by the sagittal plane (RMSD: 13.6 ± 4.7°). Statistical Parametric Mapping analysis revealed significant differences throughout most of the movement for all degrees of freedom. Maximum extension angles and velocities during the second pull displayed significant differences (p < .05) for the lower limbs. Our data showed significant differences in estimated kinematics between both systems, indicating a lack of comparability. These differences are likely due to differing models and assumptions, rather than measurement accuracy. However, given the rapid advancements of neural network-based approaches, it holds promise to become a suitable alternative to MB systems in weightlifting analysis.","PeriodicalId":14171,"journal":{"name":"International journal of exercise science","volume":"17 1","pages":"1629-1647"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11728585/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142978584","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}

We hypothesized that ACL participants would exhibit greater asymmetry between lower limbs as compared to Controls. Data were collected from 12 ACL participants and 30 Control participants. Measurements included lower limb muscle mass assessed using bioelectrical impedance, thigh circumference at 10 cm and 15 cm superior to the patella, and postural sway during single-leg stance. The results showed no significant difference in mass between the surgical and non-surgical lower limbs of ACL participants. Additionally, no significant differences were found in thigh circumference, or postural sway for ACL participants between the two limbs. In contrast, the Control group demonstrated significantly greater muscle mass (p = 0.005) in the dominant lower limbs compared to the non-dominant limbs. Thigh circumference at the 10 cm mark was also significantly greater on the dominant lower limbs than non-dominant lower limbs (p = 0.040). Our hypotheses were not supported, as asymmetry in mass and thigh circumference was demonstrated in Control but not ACL participants. No differences in postural sway were found between lower limbs in either ACL or Control participants. Loss of the ability to rely on the strength of a dominant lower limb may lead to functional deficits when participants undergo dominant limb ACL reconstruction.","PeriodicalId":14171,"journal":{"name":"International journal of exercise science","volume":"17 1","pages":"1306-1317"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11728579/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142978585","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}
