Introduction and objectives. Cardiovascular disease constitutes the first cause of death and hospitalization in Spain1, 2. This study attempts to analyze the evolution of various recovery indicators such as heart rate, ventilation and concentration of lactate within the first 20 minutes after an incremental exercise test design, using an equation that measures the recovery percentage-wise with regard to the individual functional capacity. Methods. Thirty-two young athletes performed a high-intensity incremental cycle ergometer test until exhaustion (5 watios 12 s-1). The test was preceded by 15 minutes of rest, lying face up, during which established the baseline of oxygen uptake (VO2) and carbon dioxide (VCO2). The cardiorespiratory variables were measured with a portable metabolic system (Jaeger Oxycon Pro) and the heart rate was taken with a Polar 810 (Polar Electro, Finlandia). Variables were recorded from the warm-up to the test end and 20 minutes after exercise. The subjects completed 2 min cycling at low intensity (50 watts), after 18 minutes of passive recovery. A two way repeated measures analysis of variance (ANOVA) was used. Results. After five minutes recovery, ventilation was at 85.1 (± 4.6) % of its maximum reserve, while the heart had regained 65.7 (± 6.1) % of the cardiac reserve and the concentration of lactate reached 15.4%. (±12, 9) % of the lactic reserve. After 20 minutes, subjects showed a ventilatory recovery close to 100%, while heart rate values and especially concentration of lactate were removed from the values of the line of rest. The value obtained in the ANOVA for repeated measures in the testing of the Traza of Pillai (TP), indicates a strong association between the factors ’type of recovery’ and ’time’, with a value of TP (16,174) = 1492 with p <0,001. Conclusion. The results showed that there is dissociation between the recovery of factors ventilatory compared with lactate and cardiac, which still increased after 20 minutes of recovery. Therefore, the study of post-exercise recovery rates, at a ventilatory, cardiac or metabolic level, could be applied to patients with ventilatory restrictions, and as a potential cardiac risk marker 3, 4. In addition, it could serve to check the evolution of the different parameters of recovery in a cardiopulmonary rehabilitation program. References. 1. Garcia-Dorado, D, et al.
