Hamstrings Force-Length Relationships And Their Implications For Angle-Specific Joint Torques: A Narrative Review, Eleftherios Kellis, Anthony J. Blazevich

Research outputs 2022 to 2026

Temporal biomechanical and physiological responses to physical activity vary between individual hamstrings components as well as between exercises, suggesting that hamstring muscles operate differently, and over different lengths, between tasks. Nevertheless, the force-length properties of these muscles have not been thoroughly investigated. The present review examines the factors influencing the hamstrings’ force-length properties and relates them to in vivo function. A search in four databases was performed for studies that examined relations between muscle length and force, torque, activation, or moment arm of hamstring muscles. Evidence was collated in relation to force-length relationships at a sarcomere/fiber level and then moment …

Heart rate (HR) and rate of perceived exertion (RPE) were measured throughout. Participant interview …

Metabolomics Reveals Mouse Plasma Metabolite Responses To Acute Exercise And Effects Of Disrupting Ampk-Glycogen Interactions, Mehdi R. Belhaj, Nathan G. Lawler, John A. Hawley, David I. Broadhurst, Nolan J. Hoffman, Stacey N. Reinke

Research outputs 2022 to 2026

Introduction: The AMP-activated protein kinase (AMPK) is a master regulator of energy homeostasis that becomes activated by exercise and binds glycogen, an important energy store required to meet exercise-induced energy demands. Disruption of AMPK-glycogen interactions in mice reduces exercise capacity and impairs whole-body metabolism. However, the mechanisms underlying these phenotypic effects at rest and following exercise are unknown. Furthermore, the plasma metabolite responses to an acute exercise challenge in mice remain largely uncharacterized. Methods : Plasma samples were collected from wild type (WT) and AMPK double knock-in (DKI) mice with disrupted AMPK-glycogen binding at rest and following 30-min submaximal treadmill …

Explicit And Implicit Emotion Processing In The Cerebellum: A Meta‑Analysis And Systematic Review, Jordan E. Pierce, Marine Thomasson, Philippe Voruz, Garance Selosse, Julie Péron

Center for Brain, Biology, and Behavior: Faculty Publications

The cerebellum’s role in affective processing is increasingly recognized in the literature, but remains poorly understood, despite abundant clinical evidence for affective disruptions following cerebellar damage. To improve the characterization of emotion processing and investigate how attention allocation impacts this processing, we conducted a meta-analysis on task activation foci using GingerALE software. Eighty human neuroimaging studies of emotion including 2761 participants identified through Web of Science and ProQuest databases were analyzed collectively and then divided into two categories based on the focus of attention during the task: explicit or implicit emotion processing. The results examining the explicit emotion tasks identified …

An Exploration Of The Lifestyle Of Rodeo Athletes, Brooke Tunnell, Susan Macdermott, Becki Cohill

Summer 2022 Virtual OTD Capstone Symposium

Rodeo is considered one of the most rapid-growing sports across many nations and consists of highly talented, tough athletes (Haney & Pearson, 1999). There is a gap in the research that examines the occupation of rodeo through an occupational therapy and occupational science perspective. Occupational science, the study of human occupation, focuses on how the form, function, and meaning of daily activities influence health and well-being (Larson & Zemke, 2003). Form, function, and meaning guided the mixed-method research study utilizing survey, interview, narrative prompt, and photo elicitation. Three themes were extracted from the data and embodied the personal and occupational …

Research outputs 2022 to 2026

The effect of load on time-series data has yet to be investigated during weightlifting derivatives. This study compared the effect of load on the force–time and velocity–time curves during the countermovement shrug (CMS). Twenty-nine males performed the CMS at relative loads of 40 %, 60 %, 80 %, 100 %, 120 %, and 140 % one repetition maximum (1RM) power clean (PC). A force plate measured the vertical ground reaction force (VGRF), which was used to calculate the barbell-lifter system velocity. Time-series data were normalized to 100 % of the movement duration and assessed via statistical parametric mapping (SPM). SPM …

The Role Of Ot In Adapted Crossfit, Emily Adams

Student Capstone Papers

Background: A quarter of adults are diagnosed with a disability in the United States, with almost half considered being inactive (CDC, 2020). The population of persons with disabilities (PWD) are at higher risk for secondary health concerns due to a sedentary lifestyle (Diaz et al., 2019). CrossFit recently implemented their first adaptive division in 2021 (CrossFit, LLC, 2022), however there continue to be barriers preventing PWD from participating in CrossFit.

Problem/Purpose: PWD may experience limited access to CrossFit due to structural and social barriers to access equipment and participating in movements. The purpose of this project was to …

A Smartwatch Step-Counting App For Older Adults: Development And Evaluation Study, George Boateng, Curtis L. Petersen, David Kotz, Karen L. Fortuna, Rebecca Masutani, John A. Batsis

Dartmouth Scholarship

Background: Older adults who engage in physical activity can reduce their risk of mobility impairment and disability. Short amounts of walking can improve quality of life, physical function, and cardiovascular health. Various programs have been implemented to encourage older adults to engage in physical activity, but sustaining their motivation continues to be a challenge. Ubiquitous devices, such as mobile phones and smartwatches, coupled with machine-learning algorithms, can potentially encourage older adults to be more physically active. Current algorithms that are deployed in consumer devices (eg, Fitbit) are proprietary, often are not tailored to the movements of older adults, and have …
