Introduction Insulin resistance in obesity is decreased after successful diet and exercise. Aerobic exercise training alone was evaluated as an intervention in subjects with the metabolic syndrome.

Methods Eighteen nondiabetic, sedentary subjects, 11 with the metabolic syndrome, participated in 8 wk of increasing intensity stationary cycle training.

Results Cycle training without weight loss did not change insulin resistance in metabolic syndrome subjects or sedentary control subjects. Maximal oxygen consumption (V˙O2max), activated muscle AMP-dependent kinase, and muscle mitochondrial marker ATP synthase all increased. Strength, lean body mass, and fat mass did not change. The activated mammalian target of rapamycin was ...


Analysis Of Degenerative Cervical Spondylolisthesis And Corrective Orthopaedic Implants, Tyler Heck Jun 2013

Analysis Of Degenerative Cervical Spondylolisthesis And Corrective Orthopaedic Implants, Tyler Heck

Honors Theses

Back pain is often due to the degeneration of intervertebral discs, which can lead to a condition known as spondylolisthesis, whereby a vertebra slips out of position in the anteroposterior direction. There are numerous orthopaedic implants which are used by surgeons to correct this condition; however, there has been no conclusive research conducted in comparing the efficacies of these implants. In the cervical spine, this condition most commonly occurs over two levels. For the purposes of this study, an implant’s efficacy depends on its ability to return the slipped vertebra back into natural position immediately after surgery. To test ...


History Of Concussion Research In American Football, Timothy Hersey Jun 2013

History Of Concussion Research In American Football, Timothy Hersey

Honors Theses

Concussions have been the topic of discussion in the news and media in recent years for their profound impact on today’s sport industry. Athletes have become bigger, faster, and stronger then in the past, increasing the chance of injury. This can been seen in all sports. Contact sports specifically have seen a rise in mild traumatic brain injuries (MTBIs) over the years. Extensive research has been done to determine the causes of concussion, the short and long term effects of brain injury, and better ways to reduce the risk in sports. Concussion research in athletics has mainly focused on ...


Validity Of Borg Ratings Of Perceived Exertion During Active Video Game Play, Brandon S. Pollock, Jacob E. Barkley, Nick Potenzini, Renee M. Desalvo, Stacey L. Buser, Ronald Otterstetter, Judith A. Juvancic-Heltzel Apr 2013

Validity Of Borg Ratings Of Perceived Exertion During Active Video Game Play, Brandon S. Pollock, Jacob E. Barkley, Nick Potenzini, Renee M. Desalvo, Stacey L. Buser, Ronald Otterstetter, Judith A. Juvancic-Heltzel

Health Sciences Publications

During physically interactive video game play (e.g., Nintendo Wii), users are exposed to potential distracters (e.g., video, music), which may decrease their ratings of perceived exertion (RPE) throughout game play. The purpose of this investigation was to determine the association between RPE scores and heart rate while playing the Nintendo Wii. Healthy adults (N = 13, 53.5 ± 5.4 years old) participated in two exercise sessions using the Nintendo Wii Fit Plus. During each session participants played a five-minute warm-up game (Basic Run), two separate Wii Fit Plus games (Yoga, Strength Training, Aerobics or Balance Training) for fifteen ...

Lightning Safety: How Is It Conducted At Niaaa Member High Schools?, Mauro Palmero, Andy R. Dotterweich, Gary Lhotsky, Joseph Walker Jan 2013

Lightning Safety: How Is It Conducted At Niaaa Member High Schools?, Mauro Palmero, Andy R. Dotterweich, Gary Lhotsky, Joseph Walker

ETSU Faculty Works

The purposes of this study were to explore the current scenario of interscholastic athletics in regards to the existence and enforcement of lightning safety policies applied to athletic outdoor activities, and to identify the common practices related to lightning safety currently utilized. The results showed that 87.2% of the respondents (N=804) have lightning safety policies. However, only 90.3% of the respondents who have lightning safety policies actually enforce them. It seems that during practices coaches are most commonly responsible for making the decision to stop/resume activity, and that during games athletic directors are most commonly making ...


Rate Of Torque And Electromyographic Development During Anticipated Eccentric Contraction Is Lower In Previously Strained Hamstrings [Accepted Manuscript], David Opar, Morgan Williams, Ryan Timmins, Nuala M. Dear Jan 2013

Rate Of Torque And Electromyographic Development During Anticipated Eccentric Contraction Is Lower In Previously Strained Hamstrings [Accepted Manuscript], David Opar, Morgan Williams, Ryan Timmins, Nuala M. Dear

Faculty of Health Sciences Publications

Background:

The effect of prior strain injury on myoelectrical activity of the hamstrings during tasks requiring high rates of torque development has received little attention.

Purpose:

To determine if recreational athletes with a history of unilateral hamstring strain injury will exhibit lower levels of myoelectrical activity during eccentric contraction, rate of torque development (RTD), and impulse (IMP) at 30, 50, and 100 milliseconds after the onset of myoelectrical activity or torque development in the previously injured limb compared with the uninjured limb.

Study Design:

Case control study; Level of evidence, 3.

Methods:

Twenty-six recreational athletes were recruited. Of these, 13 ...


Knee Flexor Strength And Bicep Femoris Electromyographical Activity Is Lower In Previously Strained Hamstrings [Accepted Manuscript], David Opar, Morgan Williams, Ryan Timmins, Nuala M. Dear, Anthony J. Shield Jan 2013

Knee Flexor Strength And Bicep Femoris Electromyographical Activity Is Lower In Previously Strained Hamstrings [Accepted Manuscript], David Opar, Morgan Williams, Ryan Timmins, Nuala M. Dear, Anthony J. Shield

Faculty of Health Sciences Publications

The aim of this study was to determine if athletes with a history of hamstring strain injury display lower levels of surface EMG (sEMG) activity and median power frequency in the previously injured hamstring muscle during maximal voluntary contractions. Recreational athletes were recruited, 13 with a history of unilateral hamstring strain injury and 15 without prior injury. All athletes undertook isokinetic dynamometry testing of the knee flexors and sEMG assessment of the biceps femoris long head (BF) and medial hamstrings (MHs) during concentric and eccentric contractions at ±180 and ±60° s−1. The knee flexors on the previously injured limb ...

Pilates therapy improves core muscle function and axial stability but its effects on balance in idiopathic Parkinson’s disease (IPD) have not been evaluated. The objective of this study was to evaluate the effects of a Pilates exercise program on postural stability and balance confidence in people with IPD. Ten IPD patients (Hoehn & Yahr Stage 1-3) with a history of falls or nearfalls had the following assessments before and after completion of a 6-week supervised Pilates exercise program: Activities-Specific Balance Confidence Scale (ABC), Berg Balance Scale (BBS), Schwab and England Scale (SES), Unified Parkinson’s Disease Rating Scale (UPDRS), pull-test ...
