“…Endurance sports, including long distance running, cycling and triathlon, are associated with many positive phy-siological effects, such as improvement in aerobic capacity (Saltin et al, 1968;Kasch et al, 1973), cardio-protection (Ascensao et al, 2007;Bo et al, 2014), treatment of Type I and Type II diabetes (Palermo et al, 2014;Karstoft & Pedersen, 2015;Roberts & Taplin, 2015;Ryninks et al, 2015;Yoon et al, 2015), athletic body composition (Pollock et al, 1975), and bone density (Kemmler et al, 2006;Winzenberg et al, 2006;Kemmler et al, 2015). In addition, a large body of evidence demonstrates specific benefits of endurance sports on psychological health, including protection from depressive disorders, enhanced self-esteem, an improved feeling of wellness and an increased sense of personal control (Leonardson, 1977;Greist et al, 1978;Lion, 1978;Greist et al, 1979;Jorgenson & Jorgenson, 1979). In this context, NICE (National Institute for Health and Care Excellence, London, UK) guidelines suggest that regular athletic activities (e.g., 3 times a week for 45 -60 minutes) for 10 -14 weeks can improve mild to moderate depression (Nice-Guidelines, 2009;Kim et al, 2015).…”
