Mean (±standard error) response time during C-RT and R-RT tasks. * P <0.01, light-on status vs. light-off status; †P <0.01, C-RT during light-on or -off status vs. R-RT of 25% to 75% MVC during light-on or -off status; ‡P <0.01, R-RT of 25% MVC during light-on or -off status vs. R-RT of 50% 75% MVC during light-on or -off status; §P <0.01, R-RT of 50% MVC during light-on or -off status vs. R-RT of 75% MVC during light-on or -off status; #P <0.05, C-RT vs. R-RT of 25% MVC during light-off status. C-RT, contraction response time; MVC, maximum voluntary contraction; R-RT, relaxation response time.
