Plasma creatine kinase (CK) and inflammatory biomarker levels before and after CON RX and ECC RX.

Concentric RX
	pre-exercise	immediately post-exercise	Change from pre-exercise (%)	24 hours post-exercise	Change from pre-exercise (%)
CK	60.3 ± 84.6	70.3 ± 97.9	(15.1 ± 57.9)	72.2 ± 88.2	(63.7 ± 138.1)
IL-1α	20.2 ± 47.5	16.8 ± 30.4	(55 ± 119)	20.7 ± 49.9	(14.2 ± 87.2)
IL-6	2.6 ± 3.7	2.8 ± 2.6	(79.1 ± 125.1)	2.8 ± 4.6	(−1.5 ± 57.8)
TNF-α	4.7 ± 2.1	4.8 ± 1.5	(6.3 ± 16.2)	4.5 ± 2.6	(−6.6 ± 26.8)

Enhanced Eccentric RX
	pre-exercise	immediately post-exercise	Change from pre-exercise (%)	24 hours post-exercise	Change from pre-exercise (%)
CK	54.7 ± 81.7	66.3 ± 85.4	(47.0 ± 68.8)	88.4 ± 85.4	(168.2 ± 247.2)
IL-1α	14.3 ± 27.1	21.6 ± 43.9	(66.8 ± 103.7)	19.8 ± 40.6	(60.6 ± 91.0)
IL-6	2.6 ± 3.2	3.5 ± 4.4	(75.7 ± 129.3)	2.8 ± 3.4	(24.1 ± 88.7)
TNF-α	4.0 ± 1.5	5.0 ± 2.5	(23.2 ± 23.9) *	4.5 ± 2.2	(10.8 ± 32.8)

CK = creatine kinase; IL= interleukin; TNF = tumor necrosis factor

Values are means ± SD and percent change relative to the pre-exercise time point.

^*different from the concentric group at the same time point, p<0.05.
