Analysis of maximum force (MAX); rate of force development (RFD) at 90%,75%, and 25% of maximal force (RFD90%, RFD75%, and RFD25%); and maximum of rate development (RFDmax, /sec). Force development time (sec) for maximum and 90%, 75%, and 25% of the maximum force (), fatigue resistance (sec) defined as the time at which the grip strength decreases to 50% and 25% of maximal force (FR50 and FR25), and fatigue resistance time to task failure (FRTF). Integrated area under the curve for force vs. time in the entire curve until task failure (iAUCTF). Mean and standard deviation (SD) for each. aT2D vs. ND; bBL vs. JD3, JD7, and Carryover in T2D; cBL vs. JD3, JD7, and Carryover in ND. All differences are at least .
