Thirteen male swimmers and nine non-trained male sport sciences students participated in this study. Each subject carried out 10 CMJ and 10 SJ jumps in dryland (vertical) and underwater (horizontal). During these trials, force production was recorded by force platforms and muscular activity of Vastus Lateralis, Biceps Femoris, Gastrocnemius Medialis and Tibialis Anterior was analysed through EMG. A three-way ANOVA showed that swimmers increased the differences in values obtained from SJ to CMJ between dry and underwater conditions during the first impulse phase-Impulse 1 (p less then 0.01), the second phase of impulse-Impulse 2 (p less then 0.001) and duration from peak force to take off (p less then 0.001) in contrast to non-swimmers. Patterns relating to force production and EMG were non-consistent between muscles. Jumping performance was not significantly correlated between dry land and underwater conditions; nevertheless, results emphasise that environmental constraints are decisive to define the neuro-motor response to apparently similar tasks performed in different contexts.Tools of empirical epidemiology have been and are indispensable to focus political power on blocking the spreading of coronavirus disease 2019 (COVID-19) by stopping transmission. The present paper is a comment on E. Gibney's article 'Whose coronavirus strategy worked best?' (Nature 2020;58115-6). The strategy for phase 2 should be more complex and interdisciplinary than descri
