What is the clinical evidence from this study?

Study design: RCT. Population: healthy young men (n=11). Intervention: Aerobic exercise (cycling) vs. Pre-exercise baseline. Primary outcome: Aortic (carotid-femoral) and leg (femoral-ankle) pulse wave velocity (PWV) (p=<0.05).

Acute effects of different aerobic exercise duration on pulse wave velocity in healthy young men

Q: What are the key findings of this study?

Aerobic exercise for 15, 30, and 45 minutes significantly decreased aortic and leg pulse wave velocity at 30 minutes post-exercise, with effects persisting for 60 minutes after longer durations.

11 healthy males, age 23.4±0.6 years, height 172.5±2.3 cm, weight 64.1±2.4 kg

Prolonged aerobic exercise (30-45 minutes) leads to a more sustained decrease in arterial stiffness (pulse wave velocity) during recovery compared to shorter duration (15 minutes) in healthy young men.

Resumen

BACKGROUND: The purpose of present study was to determine the acute effects of different aerobic exercise duration on pulse wave velocity (PWV) in healthy young men. METHODS: One week after measuring peak oxygen uptake to determine the duration of each exercise trial, 11 healthy males (age: 23.4±0.6 years, height: 172.5±2.3 cm, weight: 64.1±2.4 kg) cycled on an ergometer for 15 (15 min-EX), 30 (30 min-EX) and 45 minutes (45 min-EX) at 65% peak oxygen uptake in random order. After supine rest for at least 15 minutes, aortic (carotid-femoral) and leg (femoral-ankle) PWV were measured before and at 30, 60 and 90 minutes after each exercise trial. RESULTS: Compared with before exercise trials, aortic PWV decreased at 30 minutes after 15, 30 and 45 min-EX (P<0.05, P<0.01 and P<0.05, respectively) and persisted for 60 minutes after 30 and 45 min-EX (P<0.05), leg PWV decreased at 30 minutes after 15, 30 and 45 min-EX (P<0.01) and persisted for 60 minutes after 30 and 45 min-EX (P<0.01, respectively). CONCLUSIONS: These results suggest that PWV might be further decreased into recovery with prolonged exercise.
