The Effects Of A 6-Week Intrinsic Foot Morphology, Kinematics, And Kinetics In Individuals With Pes Planus, Rebecca Marszalek, Janet E. Simon, Robert Wayner

Journal of Sports Medicine and Allied Health Sciences: Official Journal of the Ohio Athletic Trainers Association

CONTEXT
The intrinsic foot muscles are vital in supporting the medial longitudinal arch of the foot. Individuals with pes planus have poor foot morphology, strength, and biomechanics, warranting an intervention.

MAIN OUTCOME MEASURES
At pre-intervention, foot posture and arch height were assessed via the Foot Posture Index-6 and the Navicular Drop test, respectively. Cross-sectional area of the abductor hallucis was assessed using ultrasound as an indirect measure of strength. Biomechanical measures, including peak rearfoot eversion, peak tibial internal rotation, peak rearfoot eversion moment, and center of pressure excursion, were collected using 3D-motion capture and an instrumented treadmill. At post-intervention, these …

Angular Momentum In Skilled Kicking Pullover Performed By Elementary School Children, Yutaka Shimizu, Saburo Nishimura, Shoichi Matsushita

Topics in Exercise Science and Kinesiology

Topics in Exercise Science and Kinesiology Volume 3: Issue 1, Article 2, 2022. This study aimed to clarify the differences in body positions and the role of the swing leg, support leg, and head-arm-trunk segment in generating and maintaining angular momentum of the whole body about a horizontal bar as well as how to improve the skill level of successful kicking pullover attempts. Two-dimensional kinematic parameters of successful kicking pullover attempts and body composition indices of 26 fifth-grade elementary school children were collected. Their techniques were classified into excellent and good groups based on the subjective evaluation of three evaluators. …

The relationship between head impact and subsequent brain injury for American football players is not well defined, especially for youth. The objective of this study is to quantify and assess Head Impact Exposure (HIE) metrics among youth and collegiate football players. This multiseason study enrolled 639 unique athletes (354 collegiate; 285 youth, ages 9–14), recording 476,209 head impacts (367,337 collegiate; 108,872 youth) over 971 sessions (480 collegiate; 491 youth). Youth players experienced 43 and 65% fewer impacts per competition and practice, respectively, and lower impact magnitudes compared to collegiate players (95th percentile peak linear acceleration (PLA, g) competition: 45.6 vs …

The Correlation Between Acl Injury & Concussion, Brandon Michael Phillips

Theses and Dissertations--Kinesiology and Health Promotion

Concussion (also known as mild traumatic brain injury) is a neurological injury that occurs after a blow to the head or neck area and can have affects to movement based on the severity of the injury. Mild traumatic brain injury has possible linkage to an increased risk of anterior cruciate ligament (ACL) injury. The purpose of this thesis was to assess the impact of prior concussion on lower extremity mechanics that are associated with risk of ACL injury. A total of 11 individuals with prior history of concussion and 11 healthy individuals without prior history of concussion (56.5 months since …
