The study objectives are the following: 1) To examine the acute vascular responses to
continuous low- and moderate-intensity exercise and interval training; and 2) To examine the
influence of age and gender on these responses.
continuous low- and moderate-intensity exercise and interval training; and 2) To examine the
influence of age and gender on these responses.
The type, intensity and duration of exercise, fitness state, and timing of measurements have
been reported to influence the acute vascular responses to exercise. However, little is known
regarding the influence of interval training, aging and gender on these responses. The
objectives of this study are: 1) to examine the acute vascular responses to continuous low-
and moderate-intensity exercise and interval training; and 2) to examine the influence of age
and gender on these responses. Subjects will perform the following 3 types of treadmill
exercise in a random order: 1) slow-pace walking; 2) moderate-pace walking; and 3) interval
training. Flow mediated dilation using high resolution ultrasonography and arterial stiffness
using applanation tonometry will be measured before, immediately after and 1-hour after each
acute bout of exercise.
