Comparison of subsarcolemmal and intermyofibrillar mitochondrial density, expressed as intensity of fluorescence, between type I and type IIA fibers before training (untrained) and after 8 weeks of harness training (trained).

	Untrained		Trained
Fiber type	Subsarcolemmal region	Intermyofibrillar region	Subsarcolemmal region	Intermyofibrillar region
Type I	59.91 (10.27–109.39)	39.48 (7.01–86.26)	54.33 (42.50–75.88)	36.48 (21.96–59.42)
Type IIA	41.67 (7.67–49.14)*	22.49 (3.81–31.13)*	33.24 (25.05–54.95)*	18.41 (12.47–39.44)*

^*Significantly different from type I, p < 0.01.

Results are given as median (minimum–maximum).
