The breath rate significantly decreased during the Olympics (mean values: 18.6/min for females, 18.5/min for males) from the pre-Olympic level (mean values: 19.3/min for females, 19.0/min for males) and returned to previous levels after the Olympics (mean values: 19.5/min for females, 19.6/min for males). The percentage of participants with a fast breath rate ( 4 20/min) varied from 9.7% to
4.9% to 30.1% among females, and from 7.9%, to 2.6%, to 27.3% among males over the three time points, respectively (Tables 3 and 4),
