| The
aim of the present study was to compare lactate removal during active
recovery performed during cycling in water immersion (CW) and during
cycling on land (CL), after a similar exercise bout in male adults.
Eleven healthy and physically active men, aged between 20 and 26 years
old participated in the experiment. Before the experimental tests,
the ventilatory threshold of the subjects was determined. Each subject
completed the experimental tests twice, with one week separating the
two periods of experiment. The subjects exercised on the treadmill
during 6 min at a speed 10% above the speed corresponding to their
ventilatory threshold. Subsequently, the subjects recovered from the
exercise bout either on a stationary bike (CL) or on a aquatic-specific
bike (CW). On the subsequent week the subjects performed the same
protocol but with a different recovery condition. Recovery condition
assignment for the first test was counterbalanced (six subjects started
with one condition and five with the other). Capillary blood samples
were collected after each test and during the recovery period (at
3, 6, 9 and 15 minutes) and blood lactate was measured. The blood
lactate values during CW were lower than during CL and significant
differences were observed at the 6th minute (p < 0.05)
and at the 15th minute of recovery (p < 0.05). Therefore,
we may conclude that active recovery using cycling in water immersion
may be more efficient than cycling on land for blood lactate removal.
