dos Reis I.G.M.
|Abstract:||Purpose: The purposes of this study were: i) to compare the physiological responses measured during a specific table tennis incremental test with the physiological responses measured during cycling, arm cranking, and treadmill running tests; and ii) to verify the accuracy of table tennis performance prediction based on the physiological responses from these tests. Methods: Eleven national level male table tennis players participated in the study and undertook incremental tests using ergometers. Table tennis performance was defined as the ranking obtained during a simulated tournament between the participants. Results: In general, peak values for physiological variables (e.g., V̇O2PEAK and [La]PEAK) were significantly lower (P<0.05) in the specific test (e.g., V̇O2PEAK =39.9±1.5ml·kg-1 per minute and [La]PEAK=6.4±0.5mmol·L-1) than during cycling (e.g., V̇O2PEAK =41.3±1.4ml·kg-1 per minute and [La]PEAK=10.2±0.7mmol·L-1) or running (e.g., V̇O2PEAK =43.9±1.5ml·kg-1 per minute and [La]PEAK=10.0±0.7mmol·L-1), but higher than during arm cranking (e.g., V̇O2PEAK =26.6±1.6ml·kg-1 per minute and [La]PEAK=8.9±0.6mmol·L-1). At respiratory compensation point intensity (RCP), only the variables measured on arm cranking were lower (P<0.05) than on the other ergometers. Stepwise multiple regression analysis showed significant correlation between table tennis performance and lactate concentration ([La]) and also rate of perceived effort (RPE) at RCP during cycling (r=0.89; P<0.05). Conclusion: In conclusion, the significant differences obtained between the specific and laboratory ergometers demonstrate the need to use a specific test to measure physiological parameters in table tennis and the physiological parameters measured, independent of the ergometer used, are unable to predict table tennis performance. © 2013 Elsevier Masson SAS.|
