Muscle, strength, and physical performance in HipFx before and after 3 mo of a multicomponent exercise training program and in comparison to matched, healthy older controls (CON)

	Pre	Post
HipFx
Quad CSA, cm2	35.5 ± 13.7	39.3 ± 13.4*
Muscle quality, N/cm2	8.6 ± 1.9	9.1 ± 1.3
Force, N	315.7 ± 168.5	358.2 ± 125.6*
Power, W	108.7 ± 73.8#	118.8 ± 55.8
6MW, m	370.0 ± 159.0#	454.4 ± 149.0*#
CON
Quad CSA, cm2	45.5 ± 15.4
Muscle quality, N/cm2	8.7 ± 2.3
Force, N	404.2 ± 196.3
Power, W	164.7 ± 104.2
6MW, m	539.8 ± 69.2

Data are means ± SD. Quadriceps (Quad) cross-sectional area (CSA), force and power in HipFx (n = 7) are data reported in the surgical leg, whereas in the healthy CON (n = 7) the data are an average of left and right legs. Quad CSA data were only acquired in 5 HipFx and 7 CON participants (see materials and methods). 6MW, 6-min walk.
