The objective was to assess the impact of dehydration on performance judokas exposed to hot environments. This is an experimental prospective study included 20 judokas a club Brazzaville. After informed consent, weight measurements, height, heart rate during exercise and the number of repetition and time to completion techniques and have been taken. These subjects were divided into two groups: non-hydrated subjects did not consume water during training sessions and topics hydrated (consuming water during training sessions). At the end of the session the beneficiaries lost a lot of weight subjects are those non-hydrated while those consuming water have hardly recorded weight losses. Heart rate increased significantly (up to 180bpm) in subjects not hydrated compared to post exercise values. It is the same for the central core temperature (7.90%). The study suggests that dehydration at a temperature of 31°C reduces physical performance outdoor practiced judo. We found significant decreases in body weight in subjects not hydrated, severe elevations in temperature and heart rate during exercise. Our results suggest that these variations are probably responsible prevalence of lower performance in non hydrated subjects.
