Key result
Water immersion during treadmill walking in healthy older adults did not significantly affect resting vagus tone or vagal changes during exercise compared to walking on land.

Does treadmill walking immersed in water alter heart rate and vagal tone compared to walking on land in healthy older adults?
Population
7 healthy older adults
Comparison

Does not support water immersion to modulate vagal tone during walking in healthy older adults; leaves open effects in clinical populations.
Does treadmill walking immersed in water alter heart rate and vagal tone compared to walking on land in healthy older adults?
p-value: p=<.05
Water immersion during treadmill walking does not significantly alter resting vagus tone or vagal changes in healthy older adults compared to land walking.
Takahashi et al. (2003) studied Healthy (n=7). Treadmill walking in water vs. Treadmill walking on land was evaluated on Heart rate and high-frequency R-R-interval variability (vagus tone) (p=<.05). Water immersion during treadmill walking in healthy older adults did not significantly affect resting vagus tone or vagal changes during exercise compared to walking on land.
