“…The use of non-drug therapies, including regular physical activity, is also reported to limit symptoms during both the PM and ME phases, both in combination with HC and not ( Matthewman et al, 2018 ; Armour et al, 2019a ; Armour et al, 2019b ; Maity et al, 2022 ; Ravichandran and Janakiraman, 2022 ). However, there is currently insufficient information to propose a consensus regarding the best physical activity type, frequency, intensity or program to reduce the frequency and severity of symptoms during both phases ( Matthewman et al, 2018 ; Armour et al, 2019a ; Armour et al, 2019b ; Ravichandran and Janakiraman, 2022 ). The combination of two systematic reviews on randomized control trials suggested that whatever the intensity, 30–60 min of aerobic exercise three to five times a week for about 10 weeks may be effective in reducing physical and psychological symptoms during the PM and ME phases ( Armour et al, 2019a ; Ravichandran and Janakiraman, 2022 ).…”
