A functional test battery (FTB), which combines the use of subjective and objective functional measures, has been proposed as a potential means to distinguish anterior cruciate ligament reconstructed (ACLR) patients' that can more safely participate in activity from those at greater risk. However, no previous study has directly assessed whether...
The ability to quickly generate torque of the triple extensors is critical during rapid movements, especially when there is not enough time to reach peak torque. Rate of torque development (RTD), which is the rate of rise of the torque-time curve, is a commonly used measure of rapid torque generation....
Although female athletes are at greater risk of non-contact knee injuries than men, the factors that contribute to these injuries are not well understood. One important question is whether intense exercise influences the risk of knee injury, both acutely
and over the following days. The purpose of this study was...
For more than 30 years, researchers have investigated the effects of whole body vibration (WBV) platforms on athletic performance. WBV is a modality in which an individual stands on a vibrating platform to obtain performance effects. Frequency and amplitude of the vibration are the commonly adjusted parameters. The use of...
This thesis explores the development of biomechanical models for evaluating a new class of passive mechanical implants for orthopedic surgery. The proposed implants take the form of passive engineered mechanisms and will be used to improve the functional attachment of muscles to tendons and bone by modifying the transmission of...
This study measured muscular strength and perceived exertion of active men, 25 to 64 years old. The subjects were 80 members of a large YMCA, with 20 active men chosen from each of the following age groups: 25-34, 35-44, 45-54,and 55-64. Measurement of strength consisted of assessing the maximum weight...
The purpose of this investigation was to determine the validity and
reliability of the Nicholas Manual Muscle Tester (NMMT), a portable
dynamometer, as a measure of the isometric strength in women with arthritis.
Female subjects (N=13; 66 ± 13.89 yrs.) with arthritis were tested for
isometric muscle strength on the...
The purpose of this study was to compare the muscular
strength and endurance of thirty-two men 51 to 79 years of age who
engage in weight training (WT), aerobic training (AT), cross training
(CT), or no training (S). The design employed in the study was a 2x2
between subjects factorial...
