RET: Resistance Exercise Training group; AET: Aerobic Exercise Training group; FLEX: Flexibility control group
All models controlled for age, baseline body mass index, and Charlson Comorbidity Index.
Original unadjusted p-values are provided followed by Bejamini-Hochberg adjusted p-values.
Negative values for chair sit and reach indicate distance between fingers and toes during reach whereas positive values indicate degree of overlap between fingers and toes. Values moving from negative to positive indicate increased range of motion
