Data in the 4 blocks to the left of each p-value are raw means ± SD for each group at baseline and follow-up. The p-value represents comparison between the groups of the follow-up least square means after adjustment for baseline. Grp = group assignment; CON = attention control; EX= endurance exercise training.
