FIGURE 4.
Change in aerobic exercise capacity during a ramp test to exhaustion after 6 weeks of twice-daily inhalation of formoterol (48 µg·day−1) in endurance-trained males (n=16) and females (n=10) versus placebo (males n=15, females n=10). Pooled data from males and females are shown (all). a) Maximal oxygen consumption (V̇O2max); b) V̇O2max relative to bodyweight (bw); c) V̇O2max relative to lean body mass (lbm); d) incremental exercise performance; e) incremental exercise performance relative to bw; f) incremental exercise performance relative to lbm, g) power output eliciting V̇O2max; h) power output eliciting V̇O2max relative to bw; i) power output eliciting V̇O2max relative to lbm. Values are effect sizes compared with placebo with 95% confidence intervals. *: p<0.05 (different from placebo within-sex); #: p<0.05 (treatment×trial interaction effect).
