Objective: To review information regarding the association of physical activity (PA) with quality of life (QoL) in the elderly and to identify the study designs and measurement instruments most commonly used in its assessment, in the period 2000-2012. Methods: Relevant articles were identified by a search of four electronic databases and crossreference lists and by contact with the authors of the included manuscripts. Original studies on the association between PA and QoL in individuals aged 60 years or older were examined. The quality of studies as well as the direction and the consistency of the association between PA and QoL were evaluated. Results: A total of 10,019 articles were identified as potentially relevant, but only 42 (0.42%) met the inclusion criteria and were retrieved and examined. Most studies demonstrated a positive association between PA and QoL in the elderly. PA had a consistent association with the following QoL domains: functional capacity; general QoL; autonomy; past, present and future activities; death and dying; intimacy; mental health; vitality; and psychological. Conclusion: PA was positively and consistently associated with some QoL domains among older individuals, supporting the notion that promoting PA in the elderly may have an impact beyond physical health. However, the associations between PA and other QoL domains were moderate to inconsistent and require further investigation.

“…On average, maximal muscle strength falls steadily from the fifth decade (Larsson et al 1979;Hughes et al 1995;Lindle et al 1997;Narici and Maffulli 2010) and accelerates from the seventh decade (Larsson et al 1979;Hughes et al 1995;Kosek et al 2006). This agerelated decline in muscular strength is associated with a reduction in general motor function, poor balance, increased risk of falls, and fractures (Campbell et al 1989;Hyatt et al 1990;Sillanpaa et al 2014) and may ultimately challenge independent living and quality of life at old age (Hyatt et al 1990;Geirsdottir et al 2012). In contrast, heavy resistance training (∼80 % of 1RM) is shown to effectively restore muscle strength in moderately old (60-75 years) subjects to a similar level as active young after only 3-4 months (Kosek et al 2006).…”

Although reductions in resting H-reflex responses and maximal firing frequency suggest that reduced efferent drive may limit muscle strength in elderly, there are currently no reports of V-wave measurements in elderly, reflecting the magnitude of efferent output to the muscle during maximal contraction. Furthermore, it is uncertain whether potential age-related neural deficiencies can be restored by resistance training. We assessed evoked reflex recordings in the triceps surae muscles during rest and maximal voluntary contraction (MVC), rate of force development (RFD), and muscle mass in seven elderly (74±6 years) males before and after 8 weeks of heavy resistance training, contrasted by seven young (24±4 years) male controls. At baseline, m. soleus (SOL) V/M ratio (0.124±0.082 vs. 0. 465±0.197, p<0.05)

Live strong and prosper: the importance of skeletal muscle strength for healthy ageing

et al. 2016

Due to improved health care, diet and infrastructure in developed countries, since 1840 life expectancy has increased by approximately 2 years per decade. Accordingly, by 2050, a quarter of Europe’s population will be over 65 years, representing a 10 % rise in half a century. With this rapid rise comes an increased prevalence of diseases of ageing and associated healthcare expenditure. To address the health consequences of global ageing, research in model systems (worms, flies and mice) has indicated that reducing the rate of organ growth, via reductions in protein synthetic rates, has multi-organ health benefits that collectively lead to improvements in lifespan. In contrast, human pre-clinical, clinical and large cohort prospective studies demonstrate that ageing leads to anabolic (i.e. growth) impairments in skeletal muscle, which in turn leads to reductions in muscle mass and strength, factors directly associated with mortality rates in the elderly. As such, increasing muscle protein synthesis via exercise or protein-based nutrition maintains a strong, healthy muscle mass, which in turn leads to improved health, independence and functionality. The aim of this review is to critique current literature relating to the maintenance of muscle mass across lifespan and discuss whether maintaining or reducing protein synthesis is the most logical approach to support musculoskeletal function and by extension healthy human ageing.
