Asea Redox Supplement Fails To Improve Aerobic Capacity And Ventilatory Threshold: A Double-Blind, Placebo-Controlled Study, Dale R. Wagner, Kyle Shegrud, Korry J. Hintze

Kinesiology and Health Science Faculty Publications

The ASEA redox cell signaling supplement beverage has been commercially available for the past decade. Despite the market longevity of this supplement, athletic sponsorship, and anecdotal ergogenic claims, there is no independent, peer-reviewed research on its efficacy. The purpose of this study was to determine if ASEA improves aerobic capacity (VO₂ max) and/or ventilatory threshold (VT) of physically active subjects. Eleven (6 females, 5 males) young adults (21.9 ± 3.9 yrs) performed 3 VO₂ max tests: (a) baseline; (b) after 2 wks of supplementing with ASEA; and (c) after 2 wks of taking a placebo in a cross-over …

An Examination Of The Present And Predictions For The Future Of Intercollegiate Athletics, James T. Morton, Donna L. Pastore

Kinesiology and Health Science Faculty Publications

This study forecasts future issues in NCAA Division I FBS intercollegiate athletics. The research design employed the Delphi technique to survey an expert panel, consisting of 12 athletic directors and associate athletic directors from FBS institutions, over three rounds to ascertain what issues are likely to occur over the next five to seven years and whether or not these issues will have a significant impact on the way intercollegiate athletics operates. Results of the study revealed eight issues that were likely to occur over the next five to seven years. Four of these issues related to the economic sector of …

College Choice Factors And Organizational Effectiveness In Intercollegiate Athletics, James T. Morton

Kinesiology and Health Science Faculty Publications

The purpose of this study was to find out if winning could be predicted by spending on facilities and coaches’ salaries by NCAA Division I intercollegiate athletic departments. Using the goals attainment model (Price, 1972) approach, winning, as measured by the National Association of Collegiate Directors of Athletics (NACDA) Cup Points, was used as the measure of organizational effectiveness for intercollegiate athletic departments. The results of a hierarchical multiple linear regression suggest that a significant proportion of the total variation in Directors’ Cup points was predicted by the combination of total annual debt service, total outstanding debt, average men’s head …

Stop-Signal Reaction Time Correlates With A Compensatory Balance Response, Garrett Rydalch, Hayden B. Bell, K. L. Ruddy, David A.E. Bolton

Kinesiology and Health Science Faculty Publications

Background

Response inhibition involves suppressing automatic, but unwanted action, which allows for behavioral flexibility. This capacity could theoretically contribute to fall prevention, especially in the cluttered environments we face daily. Although much has been learned from cognitive psychology regarding response inhibition, it is unclear if such findings translate to the intensified challenge of coordinating balance recovery reactions.

Research question

Is the ability to stop a prepotent response preserved when comparing performance on a standard test of response inhibition versus a reactive balance test where compensatory steps must be occasionally suppressed?

Methods

Twelve young adults completed a stop signal task and …

Motor Preparation For Compensatory Reach-To-Grasp Responses When Viewing A Wall-Mounted Safety Handle, David A.E. Bolton, David M. Cole, Jixun Zhan, Manhoud Mansour, Garrett Rydalch, Douglas W. Mcdannald, Sarah E. Schwartz

Kinesiology and Health Science Faculty Publications

The present study explored how motor cortical activity was influenced by visual perception of complex environments that either afforded or obstructed arm and leg reactions in young, healthy adults. Most importantly, we focused on compensatory balance reactions where the arms were required to regain stability following unexpected postural perturbation. Our first question was if motor cortical activity from the hand area automatically corresponds to the visual environment. Affordance-based priming of the motor system was assessed using single-pulse Transcranial Magnetic Stimulation (TMS) to determine if visual access to a wall-mounted support handle influenced corticospinal excitability. We evaluated if hand actions were …

Staying Upright By Shutting Down? Evidence For Global Suppression Of The Motor System When Recovering Balance, Caleigh Goode, David M. Cole, David A.E. Bolton

Kinesiology and Health Science Faculty Publications

Background

When automatic, yet unwanted action is quickly inhibited, short-lived suppression throughout the motor system ensues. This effect is referred to as global suppression. Although response inhibition is essential for behavioral flexibility, widespread motor suppression may delay action reprogramming. In reactive balance control, even fleeting suppression of the motor system could interfere with our ability to adapt compensatory reactions quickly enough to avoid a fall.

Research Question

Is muscle activity in the hand suppressed when a prepotent compensatory step becomes suddenly blocked in a balance recovery task?

Methods

Nineteen young adults were tested using a lean and release apparatus. …

Interlimb Transfer And Generalisation Of Learning In The Context Of Persistent Failure To Accomplish A Visuomotor Task, David A.E. Bolton, A. R. Buick, T. J. Carroll, R. G. Carson

Kinesiology and Health Science Faculty Publications

Transfer, in which capability acquired in one situation influences performance in another is considered, along with retention, as demonstrative of effectual learning. In this regard, interlimb transfer of functional capacity has commanded particular attention as a means of gauging the generalisation of acquired capability. Both theoretical treatments and prior empirical studies suggest that the successful accomplishment of a physical training regime is required to bring about generalised changes that extend to the untrained limb. In the present study, we pose the following question: Does interlimb transfer occur if and only if the training movements are executed? We report findings from …
