Potential Benefits Of A Minimal Dose Eccentric Resistance Training Paradigm To Combat Sarcopenia And Age-Related Muscle And Physical Function Deficits In Older Adults, Sara A. Harper, Brennan J. Thompson Nov 2021

Potential Benefits Of A Minimal Dose Eccentric Resistance Training Paradigm To Combat Sarcopenia And Age-Related Muscle And Physical Function Deficits In Older Adults, Sara A. Harper, Brennan J. Thompson

Kinesiology and Health Science Faculty Publications

The ability of older adults to perform activities of daily living is often limited by the ability to generate high mechanical outputs. Therefore, assessing and devloping maximal neuromuscular capacity is essential for determining age-related risk for functional decline as well as the effectiveness of therapeutic interventions. Interventions designed to enhance neuromuscular capacities underpinning maximal mechanical outputs could positively impact functional performace in daily life. Unfortunately, < 10% of older adults meet the current resistance training guidelines. It has recently been proposed that a more "minimal dose" RT model may help engage a greater proprotion of older adults, so that they may realize the benefits of RT. Eccentric exercise offers some promising qualities for such an approach due to its efficiency in overloading contractions that can induce substantial neuromuscular adaptations. When used in a minimal dose RT paradigm, eccentric-based RT may be a particularly promising approach for older adults that can efficiently improve muscle mass, strength, and function capacities and overall health is through heightened exercise tolerance which would favor greater exercise participation in older adult populations. Therefore, our perspective article will discuss the implications of using a minimal dose, submaximal (i.e., low intensity) multi-join eccentric resistance training paradigm as a potentially effective, and yet currently underutilized, means to efficiently improve neuromuscular capacities and function for older adults.


Association And Agreement Between Reactive Strength Index And Reactive Strength Index-Modified Scores, Talin Louder, Brennan J. Thompson, Eadric Bressel Jul 2021

Association And Agreement Between Reactive Strength Index And Reactive Strength Index-Modified Scores, Talin Louder, Brennan J. Thompson, Eadric Bressel

Kinesiology and Health Science Faculty Publications

Since the reactive strength index (RSI) and reactive strength index-modified (RSI-mod) share similar nomenclature, they are commonly referred as interchangeable measures of agility in the sports research literature. The RSI and RSI-mod are most commonly derived from the performance of depth jumping (DJ) and countermovement jumping (CMJ), respectively. Given that DJ and CMJ are plyometric movements that differ materially from biomechanical and neuromotor perspectives, it is likely that the RSI and RSI-mod measure distinct aspects of neuromuscular function. The purpose of this investigation was to evaluate the association and agreement between RSI and RSI-mod scores. A mixed-sex sample of NCAA …


Rapid Muscle Activation Changes Across A Competitive Collegiate Female Soccer Season, Kazuma Akehi, Eric C. Conchola, Ty B. Palmer, Brennan J. Thompson Jun 2021

Rapid Muscle Activation Changes Across A Competitive Collegiate Female Soccer Season, Kazuma Akehi, Eric C. Conchola, Ty B. Palmer, Brennan J. Thompson

Kinesiology and Health Science Faculty Publications

Objective: The purpose of this study was to examine the effects of a competitive soccer season on rapid activation properties of the knee extensors and flexors in Division II female soccer players. Methods: Eighteen collegiate female soccer players participated in the present study, however, due to injuries during the season a final sample of 16 players were included for study analysis. Participants performed two maximal voluntary isometric contractions (MVICs) of the knee extensors and flexors before, during, and at the end of a competitive college soccer season. Electromyography root mean square (EMG RMS; μV), rate of EMG rise (RER; %Peak …


Fatigue And The Female Nurse: A Narrative Review Of The Current State Of Research And Future Directions, Brennan J. Thompson Mar 2021

Fatigue And The Female Nurse: A Narrative Review Of The Current State Of Research And Future Directions, Brennan J. Thompson

Kinesiology and Health Science Faculty Publications

Background: The female nurse exhibits a multitude of personal and environmental characteristics that renders this population especially prone to fatigue. The consequences of fatigue in nurses are widespread and impactful at the personal, organizational, and societal levels. These include high injury rates and burnout in the nurse and poor patient and organizational outcomes. Objective: This article discusses the implications of fatigue in female nurses, including the impacts of fatigue across multiple entities (e.g., worker, patient, organization). It also reviews the current state of the research, including recent work on nurse fatigue and work schedule characteristics, and key areas for future …


Organizational Effectiveness Measures And Their Relationship To Donor Contributions, James T. Morton, Chris Hanna Jan 2021

Organizational Effectiveness Measures And Their Relationship To Donor Contributions, James T. Morton, Chris Hanna

Kinesiology and Health Science Faculty Publications

The purpose of this study was to examine the relationship between organizational effectiveness measures and donor contributions for National Collegiate Athletic Association Division I athletic departments. For this study, donor contributions were used as a proxy for donors’ perception of organizational effectiveness for these athletic departments. Using a combination of the goals attainment model (Price, 1972) and the strategic constituencies model (Connolly, Conlon, & Deutsch, 1980) the effectiveness measures used were athletic performance, student athlete welfare, and student athlete academic success. The whole of Division I, as well as the three subdivisions, were examined for the five-year period from 2013 …
