To determine if 6 weeks prior supplementation with vitamins E and C
could alleviate exercise-induced DNA damage, prevent lipid peroxidation and
inflammation, slow the rate of vitamin E utilization and/or attenuate muscle
damage, 22 subjects (11 females: 11 males) were studied during a 50 km (32
mile) ultramarathon. Subjects were...
Objective: To investigate neurocognitive effects of collegiate football players as
assessed by the Standardized Assessment of Concussion (SAC™) testing battery and a
self-reported concussion symptoms checklist.
Design and Setting: We used a one-way MANOVA to evaluate differences in
SAC™ test scores between intercollegiate football players with no history of concussion...
Discordance in bone mass between young adult swimmers and soccer players may be a direct result of differences in bone loading patterns that influence bone mineralization during growth. Our aim was to evaluate whether sports participation (soccer and swimming) had an independent effect on bone mass accrual at the hip...
The National Women's Health Information Center reports that domestic violence is the leading cause of injury to American women and that nearly one-third of American women have been physically assaulted by their significant other at some point in their lives. These women often experience depression, low self-esteem, anxiety, posttraumatic stress...
Tibial stress fractures are common in runners. However, it is unclear what factors are associated with tibial stress fractures. This study aimed to investigate 1) magnitudes of bone contact forces occurring while running 2) whether or not repeated application of running loads is sufficient to explain tibial stress fractures and...
Sex differences in bone mass and size are thought to contribute to the greater incidence of vertebral fractures in women. While these sex differences are widely recognized, the relative contributions of bone mass, bone density, and bone size to the differences in vertebral strength and fracture risk between men and...
Falls are extremely common among the older adult population, account for substantial morbidity and mortality, and are often potentially preventable. It is estimated that 9 out of 10 of hip fractures in older adults occur as the result of a fall. The economic consequences of hip fractures are estimated at...
Skeletal muscle damage induced by lengthening ("eccentric" or
"pliometric") contractions cause an immediate loss in maximal tetanic force (P₀) and an increase in protein degradation by unidentified endogenous mechanisms.
We hypothesized that increased proteolysis following active lengthening injury is
mediated by the Ca²⁺ dependent protease calpain. To test this hypothesis...
Wildland firefighters encounter many situations during forest fires that require
them to rely on their knowledge, experience, and fitness level for survival While energy
expenditure of wildland firefighters on the fire line has been well established, relatively
little is known about the physical fitness level of wildland firefighters when they...
Exercise may be the most effective strategy to reduce osteoporotic fractures in older adults because of its potential to reduce both bone loss and fall risk. It is unclear whether water exercise is an effective strategy to reduce fracture risk in postmenopausal women. PURPOSE: To examine the effects of a...
