High Intensity Cycling Before SCUBA Diving Reduces Post-decompression Microparticle Production and Neutrophil Activation

Subjects performed a repeated Wingate protocol for the exercise condition of the study. This consisted of 4, 30 s maximal efforts on a weight-braked cycle ergometer (Monark 894E, Monark Exercise AB, Sweden) with 4 min active recovery between efforts, preceded by a 5 min warm up. The resistance was set at 7.5% bodyweight for the intervals and 2% for the warm up and active recovery periods.
