Kurzfassung
This study investigated whether regular alpine skiing could reverse sarcopenia and muscle weakness in older individuals. Twenty-two older men and women (67 ± 2 yr) underwent 12 weeks of recreational skiing, 2-3 times a week, each session lasting ~3.5 hours. An age-matched, inactive group (n = 20, 67 ± 4 yr) served as control (CTRL). Before and after the training period, knee extensors muscle thickness (Tm), pennation angle () and fascicle length (Lf) of the vastus lateralis muscle, were measured by ultrasound. Maximum isokinetic knee extensor torque (MIT) at an angular velocity of 60 deg/s was measured by dynamometry. After the training, Tm increased by 7.1% (P<0.001), Lf by 5.4% (P<0.02) and by 3.4% (P<0.05). The increase in Tm was matched by a significant gain in MIT (13.3%, P<0.001). No significant changes, except for a decrease in (2.1%, P<0.02) were found in the CTRL group. The gain in Tm in the training group significantly correlated with an increase in focal adhesion kinase (FAK) content, pointing to a primary role of this mechano-sensitive protein in sarcomere remodeling with muscle hypertrophy. Overall, the results show that alpine skiing is an effective intervention for combating sarcopenia and weakness in old age.
