Background. Despite the growing popularity of kiteboard course racing, there is a paucity of scientific literature about the performance in this sport. Purpose. The aim of the present study was to analyze displacement (speed and direction) and heart rate (HR) data in high-level kiteboarders during competition. Methods. Five kiteboarders, ages 33.8 ± 5.3 years, weight: 80.6 ± 4.8 kg, height: 181.2 ± 7.8 cm, were monitored with a GPS receiver and a HR monitor during four races of the Italian Kiteboarding Championship for a total of 46 regattas. Results. Each regatta lasted 926 ± 175 s and was composed by 11 ± 1 beats. The average sailing speed recorded in competition was 8.9 ± 0.9 m/s. The speed was higher (p < 0.01) in the downwind leg (9.9 ± 1.4 m/s) than in the upwind leg (7.9 ± 0.3 m/s). The orientation of the kiteboard with respect to the wind direction during the upwind sailing phase was 66.4° ± 6.3°, resulting in been wider than in traditional sailing sports. The mean HR was 82.7 ± 0.9 % of HRreserve and 86% ± 1.2 HRmax, showing a relatively high exercise intensity compared to most of other sailing sports. Conclusion. The duration and intensity of a kiteboard racing suggest the need of specific physical training programs for competitive kiteboarders.

Abstract
Background. Despite the growing popularity of kiteboard course racing, there is a paucity of scientific literature about the performance in this sport. Purpose. The aim of the present study was to analyze displacement (speed and direction) and heart rate (HR) data in high-level kiteboarders during competition. Methods.
