a
Hodges-Lehmann estimate and exact 95% CI associated with the sign test. Confidence intervals for individual measures were Bonferroni adjusted within each multi-measure construct. No exact sign test p-value is presented as the null hypothesis of no change is inappropriate for judging equivalence.
b
1-RM, 1 repetition maximum weight.
c
DXA, dual x-ray absorptiometry.
