ABSTRACT

The results of this study showed poor reliability of exercises with the ball as suggested by the low ICC (from 0.38 to 0.72) with 95% of HR differences within ± 6.5 % to±14.2 % of HRmax. On the contrary, the circuit track HR performed without the ball used in the present investigation showed a higher reliability with ICCs ranging from 0.83 to 0.90 (from moderate to high) with total error for HR within ±2.1% and±2.5% of HRmax.
