Comparison of a continuous and intermittent triangular protocols for direct VO2max assessement

The purpose of this study was to compare two incremental protocols for V02max assessment and minimum swimming velocity that elicits V02max (vV02max). The sample comprised 11 Portuguese swimmers: 6 females (2 1.00± 1. 79 years, 54.83±3.71 kg, and 163.83±1.47 cm) and 5 males (25.40±2.79 years, 69.00±9.03 kg, and 175.00±9.03 cm). They performed two incremental protocols (starting at 0.9 m.s'\ with increments of 0.05 m.s,l per 200-m stage) for freestyle V02max assessment, with a 48h interval and in the same general conditions. One protocol was a continuous test and the other an intermittent one, with 30-s rest between incremental stages for [La-] assessment. Mean values of V02max, vV02max, VE, R, HR and [La-] for continuous and intermittent protocol, were respectively 52.5±9.44 m1.kg'l.min'l and 53.4±8.74 rnl.kg'l.min'l, 1.16±O.099 m.s) and 1.15±O.099 m.s-l, 95.3±26.32l.min,l and 95.8±26.60 l.min'l, 1.00±0.044 and 1.00±0.053, 183.l±9.47b.min'l and 187.5±8.44 b.min'l, 7.36±Ll313mM.rl and 8.86± 1.93hnM.r1. [La-] was the only different parameter between both protocols (p 0.05). Resnlts pointed out that both protocols were suitable for V02max and vV02max assessment in swimming.
