Changes in paretic knee extensor muscle strength and fatigability, as assessed by measuring maximum voluntary contractions (MVCs) of the knee extensors and the time study participants could sustain an isometric contraction equal to 30% of their MVC, in chronic stroke survivors after 2 wk of either ischemic conditioning (IC) or IC Sham training on the paretic leg. A: neither IC nor IC Sham had any effect on knee extensor MVC (P > 0.05). B: time to muscle fatigue increased from 278 ± 163 to 496 ± 313 s in the IC group (P < 0.05), whereas no change was observed in the IC Sham group (397 ± 202 s pre-IC Sham vs. 355 ± 195 s post-IC Sham; P = 0.46). Data are shown as means ± SD. NS, not significant. *P < 0.05 pre-IC vs. post-IC.
