Relative Muscular Effort In The Older Adults During The Sit-To-Stand Task: Monitoring Neuromuscular Reserve And Movement Limitations, Nayun Ahn, Michael H. Haischer, Cara L. Lewis, Kristof Kipp

Exercise Science Faculty Research and Publications

Background

Due to lower maximum strength, older adults purportedly need to exert greater muscular effort to stand up from a chair. This study investigated joint-specific muscular effort during a sit-to-stand by calculating relative-muscular-effort and investigating differences between healthy older and young adults.

Methods

Fifteen older (age: 69.9 ± 3.5 years) and 15 young (age: 22.2 ± 2.6 years) adults performed five self-paced sit-to-stand trials. Kinematic and kinetic data were collected and used to calculate inverse dynamics net joint moment. Peak isometric knee and hip extensor torques were measured and used as inputs to regression models that predicted angle- and velocity-dependent …

Downhill Running Does Not Alter Blood C1q Availability Or Complement-Dependent Cytotoxicity Of Therapeutic Monoclonal Antibodies Against Haematological Cancer Cell Lines In Vitro, Harrison D. Collier-Bain, Frankie F. Brown, Adam J. Causer, Lois Ross, Daniela Rothschild-Rodriguez, Noah Browne, Rachel Eddy, Kirstie L. Cleary, Juliet C. Gray, Mark S. Cragg, Sally Moore, James Murray, James E. Turner, John P. Campbell

Research outputs 2022 to 2026

Complement-dependent cytotoxicity (CDC) is a primary mechanism-of-action of monoclonal antibody (mAb) immunotherapies used to treat haematological cancers, including rituximab and daratumumab. However, mAb efficacy may be limited by reduced bioavailability of complement C1q – which activates the complement classical pathway following interactions with mAb-opsonised target cells. C1q is secreted by phagocytes upon recruitment to sites of muscle damage to facilitate muscular repair, hence we hypothesised that muscle damaging exercise may increase C1q ‘spill-over’ into blood. Additionally, other complement proteins (e.g., C1s) have been reported to increase following ultra-endurance and resistance exercise. Taken together, we hypothesised that muscle damaging exercise could …

Bibliometric Guide To Photographs Of Male Participants In Early Exercise And Physical Medicine Research, James L. Nuzzo

Research outputs 2022 to 2026

The history of exercise science research has undergone relatively little examination, and exercise science students receive little education about the field’s history. Photographs are tools that lecturers and writers can use to educate audiences about history. Yet, no resource exists that tells educators where they can find photographs of individuals participating in early studies about exercise or related topics (e.g., physical education, physical medicine). Here, the aim was to identify papers published before 1980 that contain photographs of boys and men participating in studies about exercise or related topics, aggregate the papers into a bibliometric list, and describe the photographs. …

Cowley, Merrill Funk, James W. Navalta Facsm, Marcus M. Lawrence

International Journal of Exercise Science: Conference Proceedings

Wearable technology is again the top fitness trend from ACSM for 2024. Our lab recently found that bicep-worn devices (Polar Verity Sense) are valid for measuring average/maximal heart rate (HR) but are not valid for estimating energy expenditure (EE) during acute resistance exercise training (RT). We postulated that the errors may have been due to the device’s algorithms assuming higher intensity during RT, but no study has directly tested these outcomes with various RT intensities. PURPOSE: To determine the concurrent validity of identical Polar Verity Sense bicep-devices to record valid measures of average and maximal HR as well as estimated …
