Figure 4. Punctate tenderness of the bilateral quadriceps of euhydrated and dehydrated participants measured preexercise and at 0.5, 24, 48, 72, and 96 hours postexercise. Values are inversely related to tenderness, ie, the lower the value, the more tenderness reported. *Significantly greater (P ≤ .001) than preexercise and 0.5 hour postexercise. †Significantly higher (P ≤ .007) than dehydration group for each time. Vastus medialis nonsignificant for group (F1,8 = 0.633, P = .449, power = .108). Rectus femoris nonsignificant for time (F5,40 = 1.016, P = .421, power = .323) and group (F1,8 = 1.235, P = .299, power = .166). Muscles tested: VM indicates vastus medialis; VL, vastus lateralis; and RF, rectus femoris.
