dc.description.abstract |
The relationship between heart rate deflection point (HRDP) and
the second ventilatory threshold (VT2) has been studied in continuous
sports, but never in a tennis-specific test. The aim of the
study was to assess the relationships between HRDP and the
VT2, and between themaximal test performance and the maximal
oxygen uptake (V_ O2max) in an on-court specific endurance tennis
test. Thirty-five high-level tennis players performed a progressive
tennis-specific field test to exhaustion to determine HRDP, VT2,
and V_ O2max. Ventilatory gas exchange parameters were continuously
recorded by a portable telemetric breath-by-breath gas
exchange measurement system. Heart rate deflection point was
identified at the point at which the slope values of the linear
portion of the time/heart rate (HR) relationship began to decline
and was successfully determined in 91.4% of the players. High
correlations (r = 0.79–0.96; p , 0.001) between physiological
(HR and oxygen uptake [V_ O2]) and performance (Time, Stage,
and Frequency of balls [Ballf]) variables corresponding to HRDP
and VT2 were observed. Frequency of balls at the HRDP
(BallfHRDP) was detected at 19.8 6 1.7 shots per minute. Paired
t-test showed no significant differences in HR (178.9 6 8.5 vs.
177.9 6 8.7 b$min21 for HRDP vs. HRVT2, respectively) at intensities
corresponding to HRDP and VT2. Maximal test performance
and V_ O2max were moderately correlated (r = 0.56; p , 0.001).
Heart rate deflection point obtained from this specific tennis test
can be used to determine the VT2, and the BallfHRDP can be used
as a practical performance variable to prescribe on-court specific
aerobic training at or near VT2. |
