“…This statement agrees with Cook et al (2015) who claim that youth with ADHD are significantly less likely than their peers to meet recommendations for vigorous PA (3 days per week or month). As mentioned, in terms of gender, according to literature girls are less active than boys (Béghin et al, 2019;Camacho-Miñano et al, 2011;Kallio et al, 2020;Lago-Ballesteros et al, 2021;Mercurio et al, 2021;Moreno-Llamas et al, 2021;Owen et al, 2017;Rosselli et al, 2020). Worryingly, in this sense, MVPA declines by approximately 4.2% to 7% per year between ages 12 and 18 years, and more recent studies indicate that girls' PA levels decline at a greater rate than boys (Borde et al, 2017;Jones et al, 2020;Owen et al, 2017;Pearson et al, 2015;Spencer et al, 2015).…”
