Effects Of Resistance Training Frequency On Muscle Function Adaptations Using A Multiple-Joint Eccentric Training Model, Joshua Crane May 2019

Effects Of Resistance Training Frequency On Muscle Function Adaptations Using A Multiple-Joint Eccentric Training Model, Joshua Crane

All Graduate Plan B and other Reports

Eccentric resistance training has been shown to be beneficial for improving multiple performance and health metrics. However, recommendations on eccentric training frequency have not been established. PURPOSE: To investigate the effects of volume-matched resistance training frequency comparing one versus three training days per week of isokinetic multiple-joint eccentric training on strength and lower body function adaptations during a 4-week training period. METHODS: Thirty recreationally-trained men and women were randomly assigned to either a high frequency (HF), three times per week, or low frequency (LF), once per week, training group for four weeks. A motor-driven isokinetic eccentric dynamometer was used for ...


Interdevice Reliability Of A-Mode Ultrasound To Measure Body Composition, Megan Bigler May 2019

Interdevice Reliability Of A-Mode Ultrasound To Measure Body Composition, Megan Bigler

All Graduate Plan B and other Reports

A-mode ultrasound is a noninvasive and rapid method for measuring subcutaneous fat thickness and estimating body fat percentage (%BF). The validity and reliability of the BodyMetrix BX2000 A-mode ultrasound has been reported; however, the purpose of this study was to compare results from two machines to determine interdevice reliability. Ultrasound measures were repeated with two BX2000 machines at 10 body sites (chest, biceps, triceps, scapula, lower back, hip, waist, thigh, calf, axilla) on 42 males of varying age and leanness (age: 28.6 ± 11.9 y, BMI: 25.4 ± 4.6 kg/m2). The intraclass correlation coefficients ranged from ...


Use Of The Wet Bulb Globe Temperature In Ncaa Fbs Athletic Training Staffs, Garrison Chan May 2019

Use Of The Wet Bulb Globe Temperature In Ncaa Fbs Athletic Training Staffs, Garrison Chan

All Graduate Plan B and other Reports

Background: Heat illnesses present a major risk for athletes, especially football players. The NATA established recommendations to prevent heat illnesses that include measuring wet bulb globe temperature (WBGT), but adherence to this recommendation is unknown.

Methods: A survey was sent to all 130 Division 1 FBS athletic training staffs to determine their use of the WBGT to assess heat stress.

Results: Of the 82 respondents (63% response rate), 59 use WBGT to assess heat stress. However, only 19 use it for summer conditioning. Of the 23 universities that do not use WBGT, 10 noted that extreme heat or humidity is ...


The Effects Of A Yoga Intervention On Cognitive Function In Older Adults, Elizabeth Edwards May 2019

The Effects Of A Yoga Intervention On Cognitive Function In Older Adults, Elizabeth Edwards

All Graduate Plan B and other Reports

Cognitive decline and reduced cognitive function presents a serious risk to the older adult population. As the population of individuals over the age of 65 continues to increase, this presents a need for effective solutions to help people sustain healthy, independent lifestyles. Currently, physical activity is recommended for physical health in older adults and has shown evidence in maintaining cognitive function. In particular, the mind-body practice of yoga is a promising form of physical exercise that shows positive cognitive benefits. While the effects of yoga appear to be promising, the current literature is lacking scientific rigor. This study investigated the ...


Staying Upright By Shutting Down? Evidence For Global Suppression Of The Motor System When Recovering Balance, Caleigh Goode May 2019

Staying Upright By Shutting Down? Evidence For Global Suppression Of The Motor System When Recovering Balance, Caleigh Goode

All Graduate Plan B and other Reports

Background: When automatic, yet unwanted action is quickly inhibited, short-lived suppression throughout the motor system ensues. This type of response inhibition causing an all-over motor suppression 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.Whether this concept of global suppression is occurring in situations that pose a postural threat is undetermined.

Research Question: Is muscle activity in the hand suppressed ...


Motor Preparation For Compensatory Reach-To-Grasp Responses When Viewing A Wall-Mounted Safety Handle, David A. E. Bolton, David M. Cole, Blake Butler, Mahmoud Mansour, Garrett Rydalch, Douglas W. Mcdannald, Sarah E. Schwartz Mar 2019

Motor Preparation For Compensatory Reach-To-Grasp Responses When Viewing A Wall-Mounted Safety Handle, David A. E. Bolton, David M. Cole, Blake Butler, Mahmoud 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 ...


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 Feb 2019

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 ...
