Body weight (mean ± SE) by time and group in each experiment. a) There was a significant time-by-group interaction (p<0.01) in the treadmill experiment. Body weight was significantly lower in TREX2 vs. CON-TREX during wks 1–10 (p=0.02) but not in TREX1 vs. CON-TREX during the same time (p=0.08). During wks 11–20, both TREX1 and TREX2 were significantly lower than CON-TREX (p<0.05): in wks 21–30, when survival in the TREX1 and TREX2 groups had fallen to less than 50%, there were no significant differences between groups (p>0.05). b) There was a significant time-by-group interaction (p<0.001) in the wheel experiment. WHL was significantly lower than CON-WHL during weeks 11–30 (p<0.001), but not during wks 1–10 (p=0.20).
