OBJECTIVES This study compared the accuracy and cost implications of using exercise echocardiography and exercise electrocardiography for detection of coronary artery disease in women. BACKGROUND The specificity of exercise electrocardiography in women is lower than in men. Exercise echocardiography accurately identifies coronary artery disease in women, but its utility in place of exercise e...

The hypothesis investigated whether exercise performance over a broad range of intensities is determined by specific skeletal muscle characteristics. Seven subjects performed 8-10 exhaustive cycle trials at different workloads, ranging from 150 to 700 W (150 min to 20 s). No relationships between the performance times at high and low workloads were observed. A relationship (P < 0.05) was notice...

background heat shock protein 72 (hsp72) is responsible for maintaining critical cellular function during heat stress. hsp72 confers thermotolerance and may play a role in heat acclimation. animal research suggests a difference between sexes in hsp72 expression in response to exercise, however, human data is lacking. conclusion our findings suggest that men and women differ in their cellular st...

The aim of this study was to examine the time course activation of select myogenic (MRF4, Myf5, MyoD, myogenin) and metabolic (CD36, CPT1, HKII, and PDK4) genes after an acute bout of resistance (RE) or run (Run) exercise. Six RE subjects [25 +/- 4 yr (mean +/- SD), 74 +/- 14 kg, 1.71 +/- 0.11 m] and six Run subjects (25 +/- 4 yr, 72 +/- 5 kg, 1.81 +/- 0.07 m, 63 +/- 8 ml.kg(-1).min(-1)) were s...

PURPOSE/OBJECTIVES To examine the demographic, medical, and social-cognitive correlates of adherence to a presurgical exercise training intervention in patients awaiting surgery for suspected malignant lung lesions. DESIGN Pilot study, single-group, prospective design with convenience sampling. SETTING Exercise training was performed at a university research fitness center in western Canada...

conclusions these findings indicate that rehydration with honey drink improves running performance and glucose metabolism compared to plain water in the heat. thus, honey drink can be recommended for rehydration purpose for athletes who compete in the heat. results running distance in run-2 covered by the subjects in the honey drink hd trial (3420 ± 350 m) was significantly (p < 0.01) longer co...

Post-exercise hypotension (PEH) plays an important role in the antihypertensive health benefits of exercise. While it has been shown that resistance exercise is effective at eliciting PEH, commonly consumed sports supplements may attenuate or completely eliminate response. Caffeine, a popular stimulant, often prior to PURPOSE: Determine effects pre-workout caffeine supplementation on PEH respon...
