Figure 1. Overview of the periodized heat acclimation (HA) protocol used for 2 elite Laser sailors preparing for the World Championships in Oman. A 4-week mesocycle included 3 heavy-build weeks and 1 recovery week (TSS = training stress score). HA (35°C, 65% RH) occurred during the first week with a heat response test (HRT) on day 1 and 5 of HA. HRTs were repeated during the two following weeks of decay (D1 and D2), and 3 d post re-acclimation (RA).
Figure 2. Mean physiological and psychophysical changes (rectal temperature, A; thermal discomfort, B; rating of perceived exertion (RPE), C; heart rate, D; plasma volume change (PV), E; and sweat rate, F) during a heat response test in hot conditions (35°C, 60% RH) from before (pre), to after heat acclimation (HA), and after 1 and 2 weeks decay (D1, D2) and 2-d re-acclimation (RA) in two elite Laser sailors (Athlete A & Athlete B).
Table 1. Individual mean power output, heart rate (HR) and power to HR ratio (Power: HR) during 45 min cycling at a clamped RPE of 13 in hot conditions (35°C, 60% RH) in elite male Laser sailors (n = 2) before (Pre), after heat acclimation (HA), after 1 (D1) and 2 (D2) weeks decay and after re-acclimation (RA).
