This study aimed to evaluate the effects of pole use on the walking vertical cost of transport (CoTvert) and foot force (FF) before and after a simulated trail running competition (STRC).Methods: Sixteen trail runners ( <math> <msub> <mrow><mover><mtext>V</mtext> <mo>˙</mo></mover> <mtext>O</mtext></mrow> <mn>2</mn></msub> </math> : 61.0 ± 8.3 ml/kg/min; ITRA performance index: 634 ± 107 points) performed walking trials with (PW) and without poles (CW) on an incline treadmill (18.6 degrees) before (PRE) and after (POST) a STRC. The course covered 31.2 km with 2086 m of elevation gain and was completed under race-simulated conditions. CoTvert and FF were measured using instrumented insoles, and axial pole force was recorded during PW.Results: The STRC was completed in 4:25:33 ± 0:39:51 (hh:mm:ss) at an average heart rate (HR) of 81.4 ± 3.8% of HRmax. Walking CoTvert showed significant time and condition effects, with higher values without poles at POST (+ 2.50 ± 2.62%, p = 0.0183). Rating of perceived exertion (RPE) was lower with poles at both PRE and POST (p = 0.0022 and p = 0.0187, respectively). FF was significantly lower with poles at PRE (p = 0.0140) and POST (p < 0.0001). Poling force decreased at POST compared to PRE (p = 0.0026).Conclusions: The main findings are that (1) CoTvert increases after STRC; (2) walking CoTvert and FF are lower with pole use and (3) upper limb force decreases at POST. These results support the use of poles in long-lasting events to reduce CoT, redistribute workload and possibly mitigate the fatigue effects.","PeriodicalId":12005,"journal":{"name":"European Journal of Applied Physiology","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144575116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, changes in CMJ performance in response to non-muscle damaging exercise, and its relation to prolonged low-frequency force depression (PLFFD) is yet unknown.Purpose: This study aimed to evaluate the relationship between PLFFD and CMJ test parameters following exhaustive cycling exercise to task failure.Methods: A sample of 11 recreationally active adults completed an incremental cycling protocol to task failure. CMJ performance, low-frequency (10 Hz) force, and maximal voluntary contraction (MVC) force output were assessed at baseline (pre-exercise), immediately after task failure (0 min), and at 8 min, 15 min, 60 min, 24 h, and 48 h post-task failure. PLFFD was assessed as the ratio of 10 Hz to MVC force.Results: Compared to baseline, PLFFD was larger from 0 min (7.4%) to 60-min (6.7%, p < 0.002). In contrast, no substantial changes in CMJ parameters were observed, except for a reduced concentric impulse (ConImp) lasting 8 min post-exercise.Conclusion: The results show that CMJ parameters remain unchanged following non-eccentrically loaded exhaustive exercise, while PLFFD is significantly higher for up to 60 min post-exercise. This raises questions about the utility of CMJ as a fatigue assessment tool in athletic populations. This suggests that CMJ testing may not effectively detect the presence of PLFFD following non-muscle damaging exercise and future research should explore alternative measures for monitoring neuromuscular fatigue in training contexts.","PeriodicalId":12005,"journal":{"name":"European Journal of Applied Physiology","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144567300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Web of Science, Medline, and Scopus were searched for studies assessing the relationship or effect between prior accumulated work and performance reductions in cyclists. Inclusion criteria required studies to measure power output after fatigue induced within a single session, with prior work quantified in kJ or other training load metrics.Results: Twenty-one studies were included in the systematic review. The primary finding was that high-intensity efforts (e.g., above critical power) led to greater power output reductions with lower accumulated work compared to low-to-moderate intensity efforts. Across studies, power output declines of 10-20% were observed after 2.5-15 kJ kg⁻1 of prior high-intensity work, whereas similar or greater work volumes at lower intensities resulted in smaller performance decrements. While kJ was the most commonly used fatigue metric, it does not account for intensity, limiting its accuracy in durability assessments.Conclusions: Exercise intensity plays a crucial role in determining durability-related performance declines. The exclusive use of kJ as a fatigue metric may be insufficient, and alternative approaches incorporating intensity are needed. These findings have implications for training prescription and race strategies, emphasizing the need for intensity-specific workload quantification.Registration: OSF project no.: osf.io/kcg53.","PeriodicalId":12005,"journal":{"name":"European Journal of Applied Physiology","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144559582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
