The significance of the test with intravenous injection of isoproterenol in the diagnosis of coronary heart disease (CHD) was evaluated in comparison with the clinical, bicycle ergometry and selective coronarography data obtained in 65 women. Twenty-four patients presented with stenosing coronary atherosclerosis and 41 patients had normal coronary arteries. On the use of the electrocardiographic signs of myocardial ischemia the sensitivity of the isoproterenol test in the diagnosis of hemodynamically appreciable coronary atherosclerosis was 74%, the specificity 78%. The sensitivity and specificity of bicycle ergometry were 66 and 90%, respectively.

Background: Effective nutritional support is essential for maintaining good performance during exercise. Taste and olfaction are key senses for food intake, and understanding how their sensitivities change during exercise is important for effective nutritional support. However, the effects of exercise on taste and odor sensitivities remain unclear.

The purpose of this study was to evaluate the effects of a microcycle of high-intensity interval training (HIT) sessions with multiple short work intervals followed by an active recovery period, compared to a similar duration of regular training, on determinants and indicators of endurance performance in well-trained cyclists. The participants in the BLOCK group performed a 6-day HIT microcycle including five HIT sessions (5 × 8.75-min 30/15 s short intervals) followed by a 6-day active recovery period with reduced training load, while the regular training group (REG) performed 12 days of their regular training, including four HIT sessions.

It is unclear whether physiological responses, such as muscle oxygen saturation (SmO), can be considered symmetrical during cycling. This knowledge has important practical implications for both training and performance assessment. The aim of this study was to determine whether oxygenation profiles in the three active muscles of both legs were symmetrical during cycling at different intensities.

There have been few studies that have examined hemodynamic responses to low-frequency neuromuscular electrical stimulation (LF-NMES), and the effects of combining passive cycle ergometry are still unclear. The purpose of this study was to examine the effects of a combination of LF-NMES and passive cycle ergometry on hemodynamic responses with a primary focus on the Fick principle in healthy adults. A randomized, crossover trial was conducted to evaluate the responses to three types of supine exercises (LF-NMES alone, LF-NMES with passive cycle ergometry, and voluntary cycle ergometry) adjusted to the same exercise intensity as the oxygen consumption of 14 mL/kg/min in 13 healthy adult men.
