Lung function trended higher in AlwO. Leg 30\u2010s work did not differ in absolute terms or per allometrically scaled LLM. Peak oxygen consumption did not differ between the groups in absolute terms or as percent predicted values (79.59\u2009\u00b1\u200914.6 vs. 82.3\u2009\u00b1\u200911.2% predicted control versus ALwO) but was lower in AlwO when expressed per kg body mass, kg lean body mass, scaled lean body mass, and LLM. Peak oxygen consumption related to both lung function and 30\u2010s work, with no observed group effect. 30\u2010s leg work related to the scaled LLM, with a small group effect. There was some correlation between leg work and time spent in moderate to vigorous physical activity in AlwO (<jats:italic>r<\/jats:italic><jats:sub>s<\/jats:sub>\u2009=\u20090.39, <jats:italic>p<\/jats:italic>\u2009=\u2009.07).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>AlwO have larger LLM and preserved exercise capacity, when expressed as percentage of predicted, but not per allometrically scaled LLM.
