The present study investigated the acute and short-term effects of oral feeding of jujube solution on blood platelets and its morphological indices in response to circuit resistance exercise. Fourteen young male volunteer students were randomly divided into the placebo and jujube solution groups. All participants performed one circuit resistance exercise[9stations/nonstop, 30 seconds for each s...

BACKGROUND The effect of moderate dehydration and consequent fluid replenishment on short-duration maximal treadmill performance was studied in eight healthy, fit (VO2max = 49.7 +/- 8.7 mL kg-1 min-1) males aged 28 +/- 7.5 yrs. METHODS The study involved a within subject, blinded, crossover, placebo design. Initially, all subjects performed a baseline exercise test using an individualized tre...

BACKGROUND Quantitative sensory testing (QST) is often used to measure children's and adults' detection- and pain thresholds in a quantitative manner. In children especially the Thermal Sensory Analyzer (TSA-II) is often applied to determine thermal detection and pain thresholds. As comparisons between studies are hampered by the different testing protocols used, we aimed to present a standard ...

In 1908, Einthovent published the first example of normal electrocardiographic responses to exercise. In 1928, Feil and Siegel2 observed abnormal downsloping ST depression and T wave inversion in three of four patients experiencing anginal attacks (presumably after climbing stairs to the phy-sician's office; H. Hellerstein, personal communication). In 1932, Goldhammer and Scherf3 associated thi...

This paper examines current concepts concerning "limiting" factors in human endurance performance by modeling marathon running times on the basis of various combinations of previously reported values of maximal O2 uptake (VO2max), lactate threshold, and running economy in elite distance runners. The current concept is that VO2max sets the upper limit for aerobic metabolism while the blood lacta...
