Values are means ± N; Significance at P < 0.05: Time: * differs from pre, ** differs from 1‐h post; Intensity: # differs from ‘−5’, ## differs from ‘+15’; CMV: ^ differs from CMV−; Main and interaction effects are F‐statistic (P‐value).
CMV, cytomegalovirus; LT, lactate threshold.
Bold values indicate P < 0.05.
