This study aims to examine the effects of high-intensity functional training (HIFT) on exercise perceptions and physiological changes in inactive females. A pre-test and post-test, quasi-experimental design was conducted with inactive, middle-aged females (n = 8) participating in an 8-week supervised and verified intervention (2-week High-Intensity Interval Training, 6-weeks HIFT). The Health Belief Model Scale for Exercise (HBMS-E) survey was completed pre-intervention, post-intervention, and 4-week follow-up to assess exercise perceptions. Pre- and post-intervention physiological assessments included: body composition, strength (1-repetition maximum (RM) bench press (BP), 5-RM deadlift (DL), and maximal oxygen consumption (V̇O2max). A within-subjects repeated-measures ANOVA assessed the HBM constructs between pre-intervention, post-intervention, and follow-up. Dependent t-tests compared physiological outcomes pre- to post-intervention. There was a significant decrease between pre-intervention, post-intervention, and follow-up for objective (F(2, 14)=22.24, p < .001) and subjective barriers (F(2, 14) = 11.20, p = .001), and a significant increase in self-efficacy (F(1.08, 7.53)= 8.96, p = .02).

This study aimed to examine the effects of a fast-velocity (FVRT) compared to a slow-velocity (SVRT) resistance training program on maximal strength, maximal movement speed, and load-velocity characteristics in older adults. Nineteen community-dwelling older adults were randomly assigned to either the FVRT or SVRT group and completed a twice weekly, progressive resistance training protocol for 8-weeks. Both groups were instructed to move the weight \"as fast as possible\" during the concentric phase of the movement and received movement velocity biofeedback. Absolute (1RMABS) and relative (1RMREL) strength, maximal movement speed (MMS), load velocity slope (LVSLOPE) and the area under the LVSLOPE (LVAREA) were measured during a 1RM assessment at baseline (PRE), after 4-weeks (MID), and after 8-weeks (POST) of training. No differences were observed in average total volume between groups (FVRT: 47490.3±10888.3 kg/session; SVRT: 44679.3±15250.9 kg/session, p = 0.26, g = 0.60). Both groups improved absolute and relative strength and maximal movement speed. There were no interaction or main effects of LVSLOPE for time. However, there was a main effect of LVAREA for time. Both MID and POST LVAREA were larger than PRE (MID posterior meandiff: 0.24, 95% CI: 0.13-0.35; POST posterior meandiff: 0.39, 95% CI: 0.27-0.49).

One-way ANOVA was employed to assess significant differences among the groups in P300 ERPs data, including amplitude and latency of waveforms, response time, and accuracy rate. Significant differences were found across the groups in various parameters.

The angle of the hip may influence the kinematics of the neck in addition to the myoelectrical activation of the surrounding musculature that contributes to the development of neck pain. The purpose of this study was to investigate the changes in spinal inclination angles and muscle activity in the neck using a 10 deg wedge in a forward slope, neutral and rear slope seated position. Forty subjects were recruited for this study. Each subject sat at a workstation under the 3 different sitting positions for ten minutes for each condition. During this time, the subjects typed a prompt for seven minutes and rested for the remaining 3 minutes. This was repeated for each position. Inclination angles and electromyography data were collected at different intervals during each trial. The results showed a significant difference in mean inclination angle among the three positions in the pain group (p<0.01). The head and neck inclination angles were higher in the rear sloped position compared to the forward slope (p<0.001). In the pain group, there was no significant change in the mean muscle activity in the UT in the forward slope as compared to the rear slope and neutral positions (p ≤0.01). The results of this study suggest that the forward sloped position provides a favorable body alignment compared to the other positions which may then lead to less unwanted muscle activation.","PeriodicalId":14171,"journal":{"name":"International journal of exercise science","volume":"17 1","pages":"1280-1293"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11728583/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142978590","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}

Healthy male participants (n = 16) performed a graded exercise test on a cycle ergometer to establish their peak power output (PPO). In subsequent visits, participants completed five different 8-minute cycling interventions, with intensities randomly assigned to one of three counterbalanced orders. HPT and PPT were applied to the thigh and forearm two times before and after each cycling intervention. Additionally, there was a notable effect of intensity on PPT in the thigh, with significant changes at intensities of 90% (p = 0.024) and 100% PPO (p = 0.003). In the forearm, repeated measures ANOVA indicated that there was no significant interaction or main effect for intensity and time. Similarly, for HPT, the analysis did not show significant interaction or main effects for both intensity and location. This study was the first to examine EIH using an 8-minute cycling intervention on a cycling ergometer at individualized intensities. Higher intensity cycling sessions generated EIH locally in the thigh using PPT. A short but high intensity cycling intervention may have clinical relevance, as it can provide an intervention to reduce localized pain immediately after exercise using a pressure pain stimulus.","PeriodicalId":14171,"journal":{"name":"International journal of exercise science","volume":"17 7","pages":"1337-1351"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11728575/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142978425","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}

Twenty participants (12 men, 8 women) completed baseline tests, including: standing broad jump (SBJ); relative SBJ; absolute and relative isometric leg/back dynamometer (LBD) and one-repetition maximum hexagonal bar deadlift (HBD). In two other sessions, participants completed four police tasks, either unloaded or loaded (PPE=~8-10 kg), in a counterbalanced order: vertical jump (VJ), 75-yard pursuit run (75PR), 74.84-kg body drag, and 500-yard run. The VJ was also used as a power metric, with peak anaerobic power and power:body mass (P:BM) derived. Paired samples t-tests investigated differences between unloaded/loaded conditions for each task for each sex. Independent samples t-tests compared the sexes. Pearson's correlations derived relationships between strength and power tests with each task TD for each sex. Load negatively impacted task performance (p≤0.011); males generally outperformed females (p≤0.044).

This study examines if it is feasible and beneficial for PWP to perform high-intensity exercise in a CBP. Seven subjects diagnosed with Parkinson's disease participated in a multimodal CBP twice a week for six weeks while wearing heart rate (HR) monitors to help maintain an HR of 70-85% of the age-predicted maximum. Subjects completed pre- and post-testing, including Functional Gait Assessment (FGA), Five Time Sit to Stand (5xSTS), Timed Up and Go (TUG), and Activities-Specific Balance Confidence Scale (ABC).

ICCs reveal good to excellent reliability between devices for back squat (PCV, 0.85-0.99; ACV, 0.83-0.99) and bench press (PCV, 0.79-0.99; ACV, 0.83-0.99). Bland-Altman plots revealed greater bias during PCV for both exercises across intensities (back squat, 0.072 to 0.110 m/s; bench press, 0.039 to 0.107 m/s), although ACV bias was lower for both exercises (back squat, -0.002 to -0.029 m/s; bench press, -0.022 to 0.015 m/s). The RepOne device generally exhibited higher smallest detectable change (SDC) values compared to the Tendo, except for specific loads in certain conditions. Additionally, the RepOne device demonstrated higher smallest worthwhile change (SWC) values than the Tendo unit for most loads in back squat ACV. Collectively, the RepOne exhibits strong validity and reliability comparable to the Tendo across both barbell back squat and bench press exercises, despite some variations in sensitivity metrics like SDC and SWC, indicating its efficacy for resistance training application.","PeriodicalId":14171,"journal":{"name":"International journal of exercise science","volume":"17 4","pages":"1250-1279"},"PeriodicalIF":0.0,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11581383/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142686484","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}
