To determine the impact of age on physiological responses during maximal deep water running compared to treadmill running under thermoneutral conditions.
Enrolled 14 young healthy non-smoking males (mean age 20.4 ± 3.3 years) and 14 middle-aged healthy non-smoking males (mean age 38.6 ± 4.4 years).
Subjects completed two maximal exercise tests—treadmill running and deep water running using a buoyancy vest—in a counterbalanced crossover sequence under thermoneutral water and ambient temperatures.
Young males achieved significantly higher relative VO2max and maximal heart rate than middle-aged males (P < 0.05), but absolute VO2max, respiratory exchange ratio, maximal ventilation, ratings of perceived exertion, and peak blood lactate showed no significant age differences.
Maximal VO2, heart rate, ventilation, and peak blood lactate were significantly lower in deep water running than in treadmill running across both cohorts, with no significant interaction between age and exercise mode except for leg perceived exertion.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Crossover trial demonstrates lower maximal cardiorespiratory responses in deep water running compared to treadmill running in men, indicating age does not alter relative water exercise deficits.
