Abstract: Goal: To analyzethe heart rate variation and to compare body weight before and after a indoor bike session, to verify the level of body dehydration. Methodology: The research features a pre-experimental research with pre and post-test delimitation. The population of this study is composed by a sample of n = 15 bike indoor users, chosen because they met the following requirements: practice for at least 6 months, age between 18 and 63 years old and frequency of at least 3 times a week. The analyzedvariables were body weight before and after exercise, and the heart rate was measured at each 5 minutes for the whole session. The analyzedsession had 45 minutes, divided in warm-up on the stationary bike for 6 min, followed by exercise with heart rate between 60% and 90% of the maximum heart rate (%MHR) for the rest of the session. Results: The age range presents an average age of 29.1 ±12.2. The heart rate on rest (HR r) of the sampled individuals presents an average of 69.2 ±4.1 bpm. The maximum heart rate (HR max) presents an average of 187.65 ±8.51 bpm. Analyzingthe body weight, it can be observed an average reduction of -1.45% of the body weight. Conclusion: The data obtained in this study show that the indoor bike session changed the statistically significant body weight, with a reduction of -1.45% and the possibility of dehydration. On the HR analysis, the indoor bike session changed the HR, oscillating between increase and decrease along the session.
