  • Values are means ± SE in ms. n, No. of echoes. Exp 1 relaxometry results for T2 values corresponding to the components described in Table 1 are shown. Component A, with a T2 value of <5 ms, was disregarded because it could not be determined with the same accuracy as those with longer T2 values. T2 components B, C, andD were resolved for all subjects. The number of subjects for whom component E could be resolved is displayed in parentheses.

  • * Significant changes after exercise (P < 0.05).
