Interval and Continuous Exercise Training Produce Similar Increases in Skeletal Muscle and Left Ventricle Microvascular Density in Rats

Table 1

Exercise performance test results and body weight of sedentary (SED), continuous-trained (CT), and interval-trained (IT) rats.

	Velocity (m/min)			Body weight (g)
	0 weeks	6 weeks	13 weeks	0 weeks	6 weeks	13 weeks
SED	24.6±1.3	19.4±1.1	14.6±1.8	276±5	371±10	436±12
