We characterized O2 consumption (VO2) during treadmill exercise in 12-, 24-, and 35-month-old Fischer 344 x Brown Norway F1 hybrid (F344BNF1) rats. When accounting for differences in body mass (Mb), (O2)peak decreased by 10% and 33% in 24- and 35-month-old rats, respectively, compared with rats at 12 months (analysis of covariance, p < .01). O2 cost per unit work at VO2peak (i.e., VO2peak/work) was greater in 35-month-old rats compared with 12- and 24-month-old rats (p < .001). During… CONTINUE READING
