Tennis ball diameter: the effect on performance and the concurrent physiological responses

image

ABSTRAK

The aim of this study was to examine the influence of a pressurized tennis ball 6% greater in diameter (Type 3) than a standard sized (Type 2) ball on performance and the physiological responses to the Loughborough Intermittent Tennis Test (LITT) (Davey et al., 2002).

Eight competitive tennis players (males, n = 4, age 24.8+3.5 years, body mass 81.3+3.1 kg, height 1.74+0.02 m, estimated V˙ O2max 54.4+2.6 ml  kg71  min71; females, n = 4, age 26.3+3.1 years, body mass 67.0+6.7 kg, height 1.68+0.02 m, estimated V˙ O2max 49.9+3.3 ml  kg71  min71; mean+sx) completed two main trials of the LITT with either the Type 2 or Type 3 tennis balls to the point of volitional fatigue.

The mean time to volitional fatigue was29.5% greater during the Type 3 trials than during the Type 2 trials (56.9+6.4 min vs 40.1+3.7 min; P50.05). The mean percentage accuracy and mean percentage consistency recorded for the entire LITT were greater for the Type 3 than the Type 2 trials (9.2+1.5 vs 4.0+0.3% and 61.1+0.6 vs 51.3+0.6%, respectively; P50.01).

A significantly lower mean heart rate and blood lactate concentration were observed during the Type 3 than during the Type 2 trials. There was a clear effect of ball diameter on tennis performance and certain physiological responses.
