“…The objective of this Special Issue on behavior analysis in health, sport, and fitness is to highlight works that offer new or innovative perspectives on the role behavior analysis plays in growing this area of research and practice via (a) informing health and fitness behavior change; (b) designing and evaluating interventions to support health-behavior change or improve fitness and sport performance; and (c) identifying opportunities and recommendations to advance research and inform practice in the areas of health, sport, and fitness. The special issue is composed of empirical studies that evaluated interventions to increase exercise and physical activity among children and adults (Batchelder & Donlin Washington, 2021; Courtemanche et al, 2021; Hanashiro-Parson & Miltenberger, 2021; Krebs & Nyein, 2021; Rosado et al, 2021; Van Camp et al, 2021), reduce rapid eating behavior (May & Catrone, 2021), and improve sports performance technique (Mulqueen et al, 2021); a review of behavioral interventions to increase physical activity of those with intellectual disabilities (Page et al, 2021); and commentary on considerations related to certification, scope of practice, scope of competence, and unique ethical situations for practitioners (Holland & Slowiak, 2021).…”
