| ABSTRACT | |||
| The aim of this study was to validate critical frequency specific
test (critf) for the estimation of the aerobic endurance in table tennis
players. Methods: Eight male international-level table tennis players participated
of this study. Specific tests were applied by using a mechanical ball thrower
to control the intensity of the exercise. The critf was determined by applying
three or four series of exercises to exhaustion (Tlim). The critf was evaluated
by using lactate steady state test (90, 100, and 106 % of critf intensity).
The other specific test was an incremental protocol used to determine the
anaerobic threshold (AnTBI) and the onset of blood lactate accumulation
(OBLA) using a ball thrower. Results: The critf (39.87 ± 3.31 balls·min-1)
was not significantly different among AnTBI (48.11 ± 7.36 balls·min-
1) and OBLA3.5 (49.36 ± 12.04 balls·min-1) frequencies
and it was correlated with AnTBI parameter (r = 0.78). At frequencies of
the 90 and 100% of critf a dynamic equilibrium was verified in lactate concentration
between the eighth and twentieth minutes. However, this dynamic equilibrium
was not found at 106% intensity. Conclusion: The data indicate that in table
tennis the critf model can be used for measuring the aerobic endurance.
Key words: Anaerobic threshold - Aerobic endurance - Blood lactate - table tennis. |
