Vascular structure changes with sprint interval or endurance training

	Sprint		Endurance
	Pretraining	Posttraining	Pretraining	Posttraining
Carotid IMT, mm	0.43±0.04	0.42±0.04	0.46±0.06	0.46±0.06
Carotid mean diameter, mm	6.3±0.3	6.3±0.3	6.2±0.5	6.1±0.5
Carotid ΔCSA within heart cycle, mm2	7.0±0.4	6.6±0.4	6.5±0.4	6.4±0.4
Carotid PP, mmHg	39±8	40±9	42±8	43±7
Popliteal mean diameter, mm	5.5±0.5	5.3±0.6	5.6±0.8	5.4±0.8
Popliteal ΔCSA within heart cycle, mm2	2.0±0.5	3.0±1.2*	2.4±1.1	3.4±1.4*
Ankle PP, mmHg	60±8	61±6	64±5	66±6

Data are means ± SD; n = 10 per group.

^*P ≤ 0.05 vs. pretraining; main effect for time. IMT, intima-media thickness; CSA, cross-sectional area; PP, pulse pressure.
