Barriers and enablers encountered by elite athletes during preconception and pregnancy: a mixed-methods systematic review.

Key recommendations developed from the results are for sporting organisations to (1) develop clear, transparent and multifaceted policies to support preconception and pregnancy; (2) foster supportive environments which offer flexible training, social support and positive promotion of pregnant athletes and (3) provide clear, evidence-based education and information about preconception and pregnancy to athletes, coaches, support staff and organisational staff.
