Acute effects of short duration maximal endurance exercise on lipid, phospholipid and lipoprotein levels.

Aim: The acute effects of maximal endurance exercise (15 min) on lipid and lipoprotein levels were examined, in order to determine whether the level of response produced could be affected by maximal exercise intensity (incremental stress test).

Methods: Participants in this cross sectional study were male athletes (n=78) of national level: basketball (n=10), swimming (n=9), long distance (LD) running (n=23) and wrestling (n=35); also a group of non-athlete volunteers as controls (n=19). Athletes had trained an average of 3 h/day and 5 years.

Comparison of respiratory response of jogging in place and Bruce treadmill exercise test.

A comparison of the respiratory responses of jogging in place, an alternative exercise test we recently proposed, was made with those of the Bruce exercise test. We obtained on-line measurements of heart rate, ventilation, oxygen uptake, and carbon dioxide production from 9 healthy subjects of mean age 25 years. There was a higher heart rate and ventilatory response with jogging than with the Bruce test, but by 10 minutes the responses of the two tests were similar.
