Relationship between ground reaction force and sacrum acceleration during 180° change of direction maneuvers in elite female basketball players
These results indicate that, despite potential software-related errors and estimation uncertainties, ACC IMU monitoring represents a promising method for estimating peak horizontal GRF rel demands during task-specific 180° COD maneuvers in real-world settings
Lower-limb strength and power characteristics in relation to 180° change of direction ability in elite female basketball players
This study examined the relationships among lower-limb strength, power, and horizontal ground reaction force (GRF) during change of direction (COD) tasks in elite female basketball players. Sixteen athletes completed an isometric mid-thigh pull (IMTP), a countermovement jump (CMJ), a lateral shuffle, and 180° turns. For the COD task, the turning distance was individualized based on each participant's standing height. Dual portable uniaxial force-…
Effects of a 7-day step taper, training cessation, and retraining on lower body physical and morphological aspects in elite female ice hockey players
Purpose This study investigated the effects of a 7-day step taper before a national championship, followed by 2 weeks of training cessation and 2 weeks of retraining on lower body physical and morphological aspects. Methods Seven elite female ice hockey players (age: 23 ± 4 years) participated in six testing sessions: two baseline sessions, one pre-championship (after taper), one after a 2-week training cessation, and two following retraining (af…
Center of mass direction and speed during a 45-degree change of direction task performed with maximal effort
Changes in whole-body center of mass (COM) direction and speed over multiple steps during a maximal effort change of direction (COD) task have not been fully examined. This study aimed to (1) quantify COM direction and speed changes across three steps -approach (APP), execution (EXE), and following (FOL)-during a 45° COD task, and (2) compare force production between EXE and FOL. Ten male American football players performed straight running (RUN)…
Training practices of Japanese elite team and combat sport athletes during the Covid-19 pandemic
Background The coronavirus disease 2019 (COVID-19) pandemic had a profound impact on the world of sports, particularly elite athletes. This study aimed to investigate how elite athletes adapted their training during the pandemic through semi-structured interviews with performance support staff from national (NT) and professional (PT) teams. Methods Thirteen Japanese support staff (NT = 9, PT = 4) provided insights into the challenges of maintaini…
Acute effect of technique modification training on 180° change of direction performance and kinematics in adolescent male soccer players
IntroductionChange of direction (COD) maneuvers are frequently performed during soccer games and are critical for performance. Adolescent players often display immature COD maneuvers, suggesting that COD technique modification training may be a more effective approach for adolescent athletes. This study investigated the acute effects of COD modification training on COD performance and kinematics in male adolescent soccer players.MethodsTwenty-nin…
Whole-Body Mechanics of Double-Leg Attack in Elite and Non-elite Male Freestyle Wrestlers
This study examined the movement characteristics of the double-leg attack in elite and non-elite wrestlers. Twenty light-weight male wrestlers were divided by skill level: Elite group (n = 11) who participated in international-level competitions and Non-Elite group (n = 9) consisting of college-level wrestlers. Each wrestler performed the double-leg attacks against a defender. Three-dimensional coordinates of anatomical landmarks and the ground r…
