A loss of muscle mass associated with reduced maximal strength is a common finding throughout the aging process; in most cases it is also associated with physical and functional decline. Aging leads to a decreased number of muscle fibers and in the cross-sectional area size—sarcopenia—being responsible for a loss of 30% of muscle mass and motor units between the age of 20 and 80 years (Fielding et al., 2011).

After training, IGF-1 increased similarly in both training groups. Similarly, other studies have shown resistance exercise training can increase IGF-1 concentrations in T2D patients (Annibalini et al., 2017), postmenopausal women with stage-1 hypertension (Son, Pekas, & Park, 2020), and healthy and sedentary subjects (Borst et al., 2001). However, IGF-1 remained unchanged after 12 weeks of combined training (30-min resistance followed by a 30-min interval or aerobic training) in Korean elderly women (Yoon, Ha, Kang, & Ko, 2019), and after 6 months of low- and high-intensity RT in healthy older persons (Borst, Vincent, Lowenthal, & Braith, 2002). To explain this discrepancy, the age of the subjects may need to be considered. It has been shown that aging is associated with sarcopenia (Buch et al., 2016). It seems that a trained individual with sarcopenia has less potential to increase IGF-1. Likewise, IGF-1 influences muscle growth and protein turnover in humans and may play an important role in exercise-induced muscular strength gains (Borst et al., 2001).

The change in aging muscle can come in two forms, namely forms that are normal (age-related sarcopenia) and abnormal (cancer-related anorexia, sarcopenic obesity, sarcopenia in cirrhosis, sarcopenia in type 2 diabetes). Sarcopenia is the age-related decrease in lean muscle mass (Evans, 2010; Siparsky et al., 2014). This phenomenon changes a person’s activeness and reduces his/her quality of life. There are three stages of sarcopenia in old people as defined by the European Working Group on Sarcopenia in Older People (EWGSOP) in 2010 (Mitchell et al., 2012). Pre-sarcopenia is only the loss of muscle mass. Sarcopenia includes muscle loss that occurs together with reduced strength or physical performance, while severe sarcopenia entails muscle loss together with loss of strength and physical performance.

In sedentary individuals >70 years old, muscle function declines of 60% have been observed compared with their younger counterparts (Close et al., 2008). Increased severity of sarcopenia reduces quality of life since older people cannot accomplish everyday tasks (Rizzoli et al., 2013). Furthermore, sarcopenia results in a substantial increase in the risk of falls and hip fractures (González-Montalvo et al., 2016) leading to a three-fold increase in mortality (Panula et al., 2001). To facilitate an increase in “active” life-expectancy, lifestyle interventions are paramount, including adopting optimal nutrition strategies combined with increased activity via the use of whole-body exercise (Abate et al., 2017). Esmarck et al. (2001) found that increasing physical activity by engaging in resistance exercise may reduce the risk of falls. The likely mechanisms responsible are the associated increases in muscle hypertrophy (Tipton & Wolfe, 2001) via the stimulation of increased muscle protein synthesis (MPS) (Damas et al., 2015). The muscle mass, and the functional gains observed in younger individuals following resistance training (Moore et al., 2004) appear to be less pronounced in the elderly (Wilkinson et al., 2018). Previous studies have shown that whilst resistance training does have some beneficial effects in the elderly, the anabolic response to exercise is blunted (Malafarina et al., 2013) and has been termed anabolic resistance.
