Intense heat and humidity could force competition schedule changes at the Tokyo Olympics and the International Olympic Committee said on Sunday it would back any such plans if needed.
Athletes across several sports have complained that competing in midday heat, where temperatures regularly hit or exceed 33 degrees Celsius (91.4°F), has hampered their performances.
High humidity has added to discomfort, and athletes have failed to find much relief from ice bags and hoses blowing cool air, part of a series of contingency measures brought in by organizers to battle the stifling heat.
