Comparative study of heart rate and estimated maximum in professional football players in different equation
Abstract
The maximum heart rate is considered the highest HR during an effort to exhaustion, being used as a criterion in progressive exercise tests. Among the equations to estimate the FCM, the equation 220-age, and the most commonly used, other equation and Tanaka et al (2001) in which overestimates the FC based on age. Thus the objective of this study was to compare the MHR obtained through exercise stress test in two groups of professional football players, with different ages, with the prediction formulas proposed by Tanaka et al. (2001) and 220 age and compare them which are closer to each group held FCM. The subjects were divided into two groups G1 (n = 11): (age: 27.4 ± 2.3, weight 76.3 ± 8.4 kg 180.9 ± 9.2 cm height) and G2 (n = 12): (age 20.5 ± 2.1, 69.5 ± 7.4 kg weight, height 175.25 ± 8.5 cm). The results showed that the FCM reached in the test G1 and G2 was similar in both formulas, regardless of age, compared with the formulas G1 has an FCM under estimated by both formulas as G2 had a high FCM in formula 220 -Age compared with FCM achieved in tests, as interesting was the change in the formula 220-age data compared to Tanaka's formula and colleagues (2001), due to age. Differ in groups of different ages, some equations may estimate an FCM, no more accurately, because individual responses, it is emphasized in athletes individuals, since margin of error is larger.
