IDENTIFICATION OF THE HEART RATE DEFLECTION POINT USING MTest
Abstract
Field tests are more specific, low-cost and require less time for their achievement in relation to
laboratory tests. Futsal lacks a physical test that approximates the reality of the game. Thus the
objective of this study is to validate a physical test for intermittent noninvasive futsal athletes
(MTest) correlating the heart rate deflection point measured with the anaerobic threshold in
cardiopulmonary exercise test. The study included 12 indoor soccer athletes of 23.5 ± 6.61 years,
height 170 ± 4.79 cm and weight 65.5 ± 8.35 kg. The subjects performed both MTest as
cardiopulmonary exercise test. In MTest the heart rate deflection point (HRDP) was identified by a
polynomial function of third order and a linear derivation. Cardiopulmonary exercise test in the ventilatory threshold was identified by the respiratory exchange ratio (VCO2/VO2). Statistical
analysis used Pearson's correlation and Student's t test (p <0.05). The HRDP (159 ± 14.54), found in
MTest correlated and no significant differences in heart rate anaerobic threshold in
cardiopulmonary exercise test evaluated, 170 ± 11.41 (r = 0.72). The MTest demonstrated its
applicability to estimate the anaerobic threshold and the coaches may perform a physical training
prescription with more quality and specificity.
