The effect of Tai Chi on cardiorespiratory function in patients with coronary artery bypass surgery

Article Abstract:

Tai Chi Chuan (TCC), a popular Chinese conditioning exercise, can enhance heart function after a coronary bypass operation. Research indicates the physiological advantage of TCC versus walking. Specifically, ventilatory threshold and peak work rate improved significantly in nine men after completing one year of TCC. The walking group realized less dramatic results.

Cardiovascular dynamics at the onset of exercise

Article Abstract:

Regional blood flow from the heart to the working muscles occurs early in exercise, according to a cardiac model. Adaptive alterations in blood flow dictate metabolic sequences within the regulatory framework. Researchers developed a cardiac model of regional blood changes in the forearm before and during exercise.

Effects of a proposed challenge on effort sense and cardiorespiratory responses during exercise

Article Abstract:

Research on how athletes' anticipation of proposed challenges while running in competition affect their performance is presented. Athletes' psychological manipulation and failure to influence cardiorespiratory response from it are discussed.
