Abstract

Compare cardiovascular responses and adaptations of a professional futsal player both at rest and in action over an uninterrupted twelve-year period. Cross-over case study. Data analysis was performed by descriptive analysis, which results are expressed as percentages (percentiles) and mean ± standard deviation (SD). The study was conducted between 1999 and 2012 sport seasons. Laboratory tests (Electrocardiogram and echocardiography, maximum stress test) and field test (competitive and training games).The VO2 max of our athlete decreased from 57.8 to 52.7 ml/kg/min however the anaerobic threshold significantly improved, as it increased from 80.4% to 92% of his heart rate maximum (HRmax). The athlete’s HRmax changed from 194 bpm in 1999 to 176 bpm in 2012 and his mean heart rate (MHR) from 168.1 ± 13 bpm to 142 ± 13 bpm. In 1999 the athlete’s performance was < 150 bpm 9.1% of time while in 2012 his heart rate (HR) was < 150 bpm 60.30% of time. In 1999, he had 150-170 bpm 32.9% of time, while in 2012 he was 39.7% of time with this HR. He changed from having a HR >170 bpm 57.8% of time in 1999 to not have this HR at any time in 2012. Comparative analysis indicated that intensity variability over a decade is < 10%, as it was 86.5% in 1999 and 80.6% in 2012. Conclusions: Age is the main factor causing heart rate variability in team sports players since maximum heart rate decreases with age. Using heart rate as an indicator of work intensity involves using relative values of percentage of work intensity with respect to their maximum heart rate.
