Abstract

The aim of the present study has been to analyze and compare the energy cost of dribbling in roller hockey with respect to the action of skating.
Twelve well-trained amateur players have carried out, during five minutes at II. 13 and 15 km/h, only skating and skating while they dribbled the ball with stick. In both cases oxygen consumption, ventilation, heart rate and subjective stress perception, were measured and compared.
The energy cost rose lineally with the velocity and was higher in all cases where the ball was dribbled while skating ( 17.50 ± 0.7 ml/kg.m Vs 20.40 ± 0.61 inl/kg.m at I I km/h; 19.23 ±0.51 nzl/kg.m Vs 24.54 ±0.76 ml/kg.m at 13 km/h; 24.84 ±0.85 inl/kg.m Vs 32.44 ± 0.71111/kg.m at 15 km/h). The ventilation and heart rate also showed a similar evolution. The levels of subjective stress perception are higher when dribbling than skating (p<.05) and higher in both cases when the velocity was higher (p<.05)
It can be concluded then that dribbling the ball while skating significantly increases the energy cost and perception subject to stress in respect to the action of only skating.
