After a 30-minute rest, the force of MVC, VA level, twitch force, and fatigue indexes
Group mean [+ or -] standard deviation for maximum voluntary contraction (MVC), General Fatigue Index
(FI), voluntary activation level (VA), Central Fatigue Index
(CFI), twitch force, Peripheral Fatigue Index
(PFI), and Modified Fatigue Impact Scale (MFIS) before and after 8 weeks of surface functional electrical stimulation (FES) training.
The first verification of the mechanical fatigue index
(FI) was determined by the use of the equation: FI = ([P.sub.maximum] - [P.sub.minimum]) x 100 / [P.sub.peak].
 Dimitrov's spectral fatigue index
One important finding in the current study is the fatigue index
was greater after AR alone than after AR combine with SS.
(%) = 100% - [MVIT.sub.post20]/[MVIT.sub.prs] x 100%
Statistical analysis for Mean Power Output, Maximum Power Output, Minimum Power Output and Fatigue Index
for scores expressed in relative to body mass showed significant differences between slow music and no music conditions, fast music and no music conditions, but no significant differences between slow and fast music conditions.
A variable dynamometric fatigue index
was used to ensure that the fatigue induction occurred similarly in all groups.
indicates the decrease in power from the highest to the lowest anaerobic power output.
The percentage of decrease in power or fatigue index
(FI), is the difference between the instantaneously 1-s highest and lowest powers divided by the highest power.
The aim of this study was to compare variables related to asymmetry, peak torque, and fatigue index
in the Traditional strength training method and the Kaatsu strength training method, which is a blood flow restriction training strategy.
However, they didn't find a significant music effect in the mean power ([P.sub.mean]) and the fatigue index
. In physically active men, Chtourou et al  found that music during warm-up enhanced the [P.sub.peak] and [P.sub.mean] during the same exercise.
