However, exploration into how external pelvic loading may be altered during running is limited. This study assessed which biomechanical variables influence changes in external peak pelvic acceleration during treadmill running, across various stride frequency conditions. Twelve participants (7 female, 5 male) ran (9 km∙h-1) at their preferred stride frequency, and at ± 5% and ± 10% of their preferred stride frequency. Coordinate and acceleration data were collected using a motion capture system and inertial measurement units. Linear mixed models assessed peak tibial acceleration, displacement from hip to knee and ankle, contact time, and stride frequency as predictors of peak pelvic acceleration. Stride frequency and contact time interacted to predict peak vertical (p = .006) and resultant (p = .009) pelvic acceleration. When modelled, short contact times and low stride frequencies produced higher peak vertical (p = .007) and resultant (p = .016) pelvic accelerations than short contact times and average, or high stride frequencies. Increasing contact time, or increasing stride frequency at shorter contact times, may therefore be useful in reducing pelvic acceleration during treadmill running.","PeriodicalId":49482,"journal":{"name":"Sports Biomechanics","volume":" ","pages":"1-15"},"PeriodicalIF":2.0,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143015075","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}

HADd (p = 0.361) and external rotation (p = 0.935) ROM exhibited no changes between pre-and post-pitching.

The purpose of this study was to investigate differences in SLHH biomechanics between masters runners with and without AT. 32 masters runners age 50 and older with AT (60.31 ± 8.37, n = 16) and without (59.94 ± 4.95 n = 16) were included. 3D motion capture and force plates were used to assess hopping biomechanics. Masters runners with AT had significantly lower peak ankle plantarflexion positive power peak hip extensor positive power and peak hip extension moments compared to healthy controls. No differences in peak ankle plantarflexion moments and knee kinetics were observed between groups. Masters runners with AT demonstrate altered lower extremity biomechanics during the propulsive phase of the SLHH, suggesting they may not be able to appropriately generate forces and release stored energy from the Achilles tendon during maximal efforts.","PeriodicalId":49482,"journal":{"name":"Sports Biomechanics","volume":" ","pages":"1-11"},"PeriodicalIF":2.0,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143015074","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, research has yet to offer a thorough understanding of whether coordination variability is altered in response to different synthetic and natural turf surfaces. The purpose of this study was to investigate lower extremity coordination variability during hopping and running on four turf surfaces-three synthetic and one natural. Continuous relative phase (CRP) variability of six segment couplings was computed to examine coordination variability during the braking and propulsion sub-phases of running and hopping. Coordination variability in the sagittal plane pelvis-thigh coupling during the braking sub-phase of hopping was significantly affected by turf surface (χ2 (3) = 8.365, p = .039), with significantly less CRP variability observed on the firmest of the synthetic surfaces compared to the natural turf (55.3° ± 16.8° vs. 67.1° ± 17.2°, p = .032, W = .16). No other significant surface effects were observed. Our findings suggest that lower extremity inter-segmental coordination variability is largely unaffected by different turf surfaces during an acute exposure. However, the reduced variability observed between the pelvis and thigh during hopping may indicate decreased flexibility of the motor system and warrants further attention.","PeriodicalId":49482,"journal":{"name":"Sports Biomechanics","volume":" ","pages":"1-21"},"PeriodicalIF":2.0,"publicationDate":"2025-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142972895","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}

We examined the influence of increasing cadence on peak joint angles, moments and powers, and ground reaction forces in long-distance runners. We collected three-dimensional kinematics and kinetics for 31 high school cross-country runners during overground running at their preferred cadence (baseline), +5%, and +10% baseline cadence. We performed repeated-measures ANOVAs to compare peak joint angles, moments and powers, and ground reactions forces among cadence conditions. Increasing cadence reduced peak pelvis, hip, knee, and ankle joint angles (p ≤ .01), peak knee moment and powers (p < .001), peak ankle power (p ≤ .01), and peak ground reaction forces (p ≤ .01) but increased peak hip moment and powers (p < .001). Increasing cadence by 10% elicited greater magnitude changes compared to increasing cadence by 5%. Increasing cadence may be a beneficial intervention to reduce lower extremity peak joint angles and knee kinetics for adolescent long-distance runners. The increase in hip kinetics when running at a higher than preferred cadence indicates this intervention increases the loads applied to the hip for adolescent long-distance runners.","PeriodicalId":49482,"journal":{"name":"Sports Biomechanics","volume":" ","pages":"1-14"},"PeriodicalIF":2.0,"publicationDate":"2025-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142957807","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}

The horizontal CoM velocity and vertical CoM position from the water surface were calculated for one stroke cycle and divided into five stroke phases: entry, pull, push, release, and recovery. Linear mixed-effects model analysis revealed a positive trend between the mean swimming velocity and the mean vertical CoM position for each stroke phase (p < 0.001 for all phases). The interaction term between stroke phase and swimming velocity was significant (p < 0.001), and the slopes of the propulsive phases (pull and push) were larger than those of the non-propulsive phases (entry, release, and recovery) (p < 0.001).
