with a standard suit (SS). The statistical analysis was performed using
Student t tests.
The second part was a clinical case study. The subject was an international
swimmer, a member of the French national swim team for many
years (31 years old, 190cm, 89kg), and was a specialist of short distances
in front crawl swimming (93.93% WR on the 50-m event, and 93.98%
WR on the 100-m event). This swimmer performed the whole experiment
four times: in a standard suit, in an Arena Extrem® suit, in an
Arena Powerskin-Revolution® suit and in a Speedo LZR® suit.

The results of the first part of this study showed no significant differences
in buoyancy, glide or passive torque. A significant decrease in IdC
(Fig. 1a) and the percentage of propulsive phase of the stroke (Fig. 1b)
was detected by looking at the average values (without taking into account
the velocities).
