[en] Ageing-related loss of muscle mass and strength, referred to as sarcopenia, is a major health issue, given the importance of skeletal muscles in movement, metabolism, disease, quality of life and independence. Accordingly, exercise interventions are advocated for older adults to restore or minimize sarcopenia. However, walking and even conventional resistance exercises may not provide sufficient effects on sarcopenia.
Eccentric resistance exercise has been paid more attention as a method to improve muscle strength and mobility in older adults. Eccentric muscle contractions occur when muscles are lengthened while being activated, produce greater force with lower metabolic cost in comparison to isometric and concentric muscle contractions. Eccentric muscle contractions are therefore suitable stimulus for muscle hypertrophy and strength without being accompanied by large cardiorespiratory demands, which may be an obstacle for compliance to an exercise programme. However, it is still not clear yet how to prescribe eccentric exercise training to prevent sarcopenia and optimize strength gain safely in older adults.
This symposium consists of three state-of-the-art presentations on why resistance training is necessary for the ageing population (Lecture 1), what are the basics for significance of eccentric exercise training (Lecture 2) and how to implement it in older adults (Lecture 3), providing thereby new perspectives for exercise intervention as a countermeasure to sarcopenia.
