Exercise training has consistently been shown to increase fat utilization during exercise, while conflicting results have been reported on the effects of sex and age on fuel metabolism during exercise. PURPOSE: The primary objective of this investigation was to compare fat and carbohydrate utilization during exercise among males and females...
The purpose of this study was to identify significant differences
in body composition, body cathexis, and attitudes toward obesity
of women in various age groups involved in different levels of physical
exercise.
A total of 216 women, ranging in age from 17 to 64, took part in
this study. They...
The purpose of this study was to compare the levels of bone
mineral density (BMD) of the whole body (WB) and proximal
femurs of physically active men with spinal cord injuries (SCI) to
nonactive men with spinal cord injuries. Also, the lean muscle
mass (LMM) of active men with SCI...
The purpose of this study was to examine the validity and reliability of the 30-minute cycling time trial to estimate the heart rate at lactate threshold. Recreationally trained cyclists and triathletes (n = 47) performed 3 tests in random order: 1) One graded exercise test to directly determine lactate threshold...
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...
Studies in young women show that rowing exercise is osteogenic at the spine. However, little is known regarding rowing exercise and spine bone mineral density in older women. The aim of this study was to examine differences in spine bone mineral density (BMD) and back strength between premenopausal and postmenopausal...
Four young trained men were studied during 50 min of continuous
bicycle ergometer exercise [30 min at 60%, 15 min at 80%,
and 5 min at 90% maximal heart rate (MHR)] to elucidate changes
in fuel metabolism resulting from a glycogen depletion-repletion
regimen, and to determine the effect of supplemental...
The goal of this study was to determine if the cardiorespiratory adaptations to an eight-week circuit weight training program are better measured with a biokinetic swim-bench test versus a standard treadmill test. The working hypothesis of the study was that since standard circuit weight training programs stress the upper body...
Metabolic syndrome (MetS) and abdominal obesity (AbOb) increase the risk of
developing cardiovascular disease and diabetes. Energy restriction (ER), highprotein
(PRO) intake and high-intensity interval training (HIT) can independently
improve MetS and AbOb. However, ER reduces metabolically active lean body
mass (LBM) in addition to body fat (BF). Purpose: To...
