V̇O2, Ė and C remain constant as a function of time at intensities up to MLSS.
V̇O2, Ė and C still remain constant as a function of time at 102.5%MLSS.
Hyperventilation and decreased OUE are observed as a function of time at 102.5%MLSS.
Biomechanics factors are compromised as a function of time at 102.5%MLSS.
Bioenergetical and biomechanics changes at 102.5%MLSS reduce swim ability.
