The existence of “athlete’s heart” is generally accepted, but the question of whether athletes exhibit vascular adaptation has not been fully addressed.

PURPOSE: Investigated the indexes of arteries to determine whether arterial adaptations induced by exercise exist.

METHODS: Examined the arteries of the dominant (D) and nondominant (ND) limbs of athletes and inactive subjects by duplex ultrasound.

RESULTS: 1. In tennis athletes, IMT-to-lumen of arteries were lower than controls (carotid D: 0.013 ± 0.003 vs. 0.015 ± 0.003, ND: 0.013 ± 0.002 vs. 0.015 ± 0.003; brachial D: 0.026 ± 0.002 vs. 0.039 ± 0.011, ND: 0.038 ± 0.009 vs. 0.042 ± 0.013; p < 0.05). We found larger cross-sectional area of brachial artery (D: 20.96 ± 1.79 mm2) relative to the ND side (16.72 ± 0.93 mm2, p < 0.05) and both sides of controls (D: 13.37 ± 0.92 mm2, ND: 13.37 ± 0.85 mm2; p < 0.05). 2. Football athletes demonstrated lower IMT-to-lumen compared with controls (carotid D: 0.013 ± 0.002 vs. 0.015 ± 0.003, ND: 014 ± 0.003 vs. 0.015 ± 0.003; brachial D: 0.031 ± 0.009 vs. 0.039 ± 0.011, ND: 0.034 ± 0.010 vs. 0.042 ± 0.013; radial D: 0.075 ± 0.014 vs. 0.089 ± 0.018, ND: 0.087 ± 0.027 vs. 0.106 ± 0.021; femoral D: 0.013 ± 0.003 vs. 0.016 ± 0.006, ND: 0.013 ± 0.004 vs. 0.017 ± 0.005; p < 0.05). We found larger cross-sectional area of femoral artery (D: 42.59 ± 1.88 mm2) relative to the ND side (36.70 ± 1.75 mm2, p < 0.05) and D side of controls (34.87 ± 1.50 mm2, p < 0.05). 3. Swimmers demonstrated lower IMT-to-lumen compared with controls (carotid D: 0.013 ± 0.003 vs. 0.015 ± 0.003, ND: 0.014 ± 0.002 vs. 0.015 ± 0.003; brachial D: 0.028 ± 0.004 vs. 0.039 ± 0.011, ND: 0.033 ± 0.006 vs. 0.042 ± 0.013; radial D: 0.071 ± 0.021 vs. 0.089 ± 0.018, ND: 0.085 ± 0.019 vs. 0.106 ± 0.021; femoral D: 0.013 ± 0.002 vs. 0.016 ± 0.006, ND: 0.014 ± 0.003 vs. 0.017 ± 0.005; p < 0.05). The cross-sectional area of brachial (D: 17.36 ± 0.90; ND: 16.83 ± 0.67 mm2) and femoral arteries (D: 41.33 ± 1.63; ND: 39.05 ± 1.28 mm2) were larger than controls (brachial D: 13.96 ± 0.95 mm2, ND: 13.37 ± 0.85; femoral D: 34.87 ± 1.50 mm2, ND: 34.55 ± 1.62 mm2; p < 0.05).

CONCLUSION: The results suggest that “athlete’s artery” has a systemic decreased wall thickness and a localized increased lumen area. These structural changes of artery are adaptations to exercise.
