In the experimental leg, arterial CSA increased 16% (from 84 +/- 3 to 97 +/- 5 mm2) and venous CSA increased 46% (from 56 +/- 5 to 82 +/- 5 mm2) after endurance training, which returned to baseline during detraining.

Overview

Supports localized vascular adaptation to unilateral training in healthy men; leaves open translation to patients or outcome impact.

Structured PICO

Does one-legged endurance training increase femoral arterial and venous size in healthy young men?

P
Population
10 healthy young men
I
Intervention
One-legged cycle training (80% of one-legged peak O2 uptake, 40 min/day, 4 days/wk) for 6 weeks followed by 6 weeks of detraining
C
Comparator
Control leg (untrained leg)
O
Outcome
Cross-sectional area (CSA) of the common femoral artery and vein (via B-mode ultrasound) and one-legged VO2 peaksurrogate

Regional increases in blood flow from endurance training are associated with localized femoral arterial and venous expansion, which reverses with detraining.
