TRAINING AND PERSONALITY AS DETERMINANTS OF EXERCISE HYPERVENTILATION; FACTORS AFFECTING THE TESTING OF PHYSICAL INCAPACITATION IN MAN
Abstract
Ventilatory and cardiac responses to the riding of an electrically braked bicycle ergeter have been investigated in young male subjects during a variety of short intensive training regimes involving both maximal and sub-maximal work. With 'maximal effort' rides of 5 min duration, there was an increase in the rate of working over the training period (greater with 1 ride per day than with three rides per day), and this increase was sufficient to mask any improvement of cardio respiratory performance. With longer periods (15 to 30 min) of heavy but sub-maximal work, there was a progressive reduction of both the ventilatory and the cardiac response to exercise, and calculations suggested that the efficiency of external work was also increased. The magnitude of these changes could be related to initial 'fitness'. Changes in respiratory quotient with repetition of the sub-maximal rides suggest that with habituation, there was less hyperventilation. Both at rest and during exercise, the cardiorespiratory performance could be related to personality type, as assessed by the Maudsley Personality Inventory.
