Qtc Is Associated With Obesity And Physical Activity Level For African American Females, C. Jayne Brahler Apr 2004

Qtc Is Associated With Obesity And Physical Activity Level For African American Females, C. Jayne Brahler

Health and Sport Science Faculty Publications

Long QT syndrome (LQTS) is an independent risk factor for cardiovascular or ischemic disease mortality. Obesity as a cause for acquired LQTS in otherwise healthy individuals is rapidly gaining the attention of the scientific community. African American people have a higher incidence of obesity compared to Caucasians, yet race-specific information is not available for their prevalence of LQTS. Chronic physical activity can help reduce the incidence of obesity, yet little is known about the effects of chronic physical activity on acquired LQTS. Subjects in this study were a volunteer sample of African American mothers (21-53 yr, n = 44) and …

Thoracic Pain In A Collegiate Runner (Case Report), Gary P. Austin, W. T. Benesky

All PTHMS Faculty Publications

This case study describes the process of examination, re-examination, and intervention for a collegiate runner with mechanical thoracic pain preventing athletic participation and limiting daily function. Unimpaired function fully returned in less than 3 weeks with biweekly sessions to re-establish normal and painfree thoracic mechanics via postural hygiene, exercise, mobilization, and manipulation. The outcome of this case study supports the original hypothesis that the pattern of impairments was in fact responsible for the functional limitations and disability in this athlete. At the time of publication the athlete was without functional limitations and had fully returned to competitive sprinting for the …

Effect Of Added Mass On Human Unipedal Hopping, Gary P. Austin, Gladys E. Garrett, David Tiberio Jun 2002

Effect Of Added Mass On Human Unipedal Hopping, Gary P. Austin, Gladys E. Garrett, David Tiberio

All PTHMS Faculty Publications

Although hopping is considered a children's activity, it can be used to provide insight into the neuromuscular and biomechanical performance of adults. This study investigated whether mass added during unipedal hopping altered the vertical stiffness, hopping period, and angular kinematics of the lower exteremity of adults. Measures of two-dimensional kinematics and vertical force were made from 10 healthy men during hopping at a preferred period under three conditions: Body Mass, Body Mass +10%, and Body Mass +20%. Adding mass significantly increased hopping period and hip flexion without significantly affecting vertical stiffness, ankle dorsiflexion, or knee flexion. Overall, the findings agreed …

The Effects Of A Functional Derotational Knee Brace On The Single-Leg Hop, Timed-Hop, And Stability Of Ncaa Division Ii Athletes, Heidi E. Moran Jan 2000

The Effects Of A Functional Derotational Knee Brace On The Single-Leg Hop, Timed-Hop, And Stability Of Ncaa Division Ii Athletes, Heidi E. Moran

Theses, Dissertations and Capstones

Functional knee braces are often used by athletes following an injury to their anterior cruciate ligament (ACL). However, few athletes are given information as to whether the knee brace will hinder their ability. The purpose of this study was to examine the effects of a functional derotational knee brace on the single leg hop for distance, timed hop, and overall stability index of athletes. Twelve healthy knees were tested with and with out an off-the-shelf DonJoy Legend knee brace. A matched T-test showed a significant difference between the single leg hop (T = 2.71, p<.05) and timed hop (T=3.23, p<.05) while wearing the knee brace. There was no significance found when examining the stability index while wearing the brace. It was concluded that the functional knee brace decreased the distance of a single leg hop and increased the time it took to perform a timed hop.
