We investigated the effect of alpine skiing for 12 weeks on skeletal muscle characteristics and biomarkers of glucose homeostasis and cardiovascular risk factors. Twenty‐three patients with a total knee arthroplasty ( TKA ) were studied 2.9 ± 0.9 years (mean ± SD ) after the operation. Fourteen patients participated in the intervention group ( IG ) and nine in the control group ( CG ). Blood samples and muscle biopsies were obtained before ( PRE ) and 7.3 ± 0.8 days after ( POST ) the intervention, and blood samples again after a retention ( RET ) phase of 8 weeks. With skiing, glucose homeostasis improved in IG (decrease in fasting insulin, increase in muscle glycogen) but not in CG . Fiber type distribution and size, as well as capillary density and number of capillaries around the fibers ( CAF ), were not different between the operated and the non‐operated leg in either group. The relative number of type I fibers increased with skiing in IG with no change in CG . Inflammatory biomarkers, plasma lipids, and mitochondrial proteins and activity did not change. Alpine skiing is metabolically beneficial and can be used as a training modality by elderly people with TKA .
