What statistical test to use??

[Jaysun]

I am looking for the correct test to use to quantatively analyze the following problem. I have 2 groups, 2 time points (pre and post test) and 1 DV (VO2max)

I am investigating the effects of 2 different interventions (aerobic training and resistance+aerobic training) on the VO2max (max O2 uptake) in elderly adults. Subjects will be randomly assigned to the AT or RT+AT. The will complete a treadmill test before and after the 8 week interventions. I am trying to determine if the RT+AT group increases VO2max more than the AT group.

I do not know what test(s) to use...

this is classic regression discontinuity,
