Key result
Ergometry rowing elicits a ~9 bpm lower HR than treadmill running at equivalent lactate levels.
Why the study?
Exercise intensity in older people is often determined by heart rate or percentage of maximal heart rate, but differences in heart rate response between ergometry rowing and treadmill running are not well characterized.
Does ergometry rowing compared to treadmill running alter heart rate and oxygen uptake responses in older people?

Absolute Event Rate: 151% vs 160%
p-value: p=<0.05
In older adults, ergometry rowing elicits a lower heart rate response but higher oxygen uptake compared to treadmill running, indicating that exercise prescriptions based on heart rate need modality-specific adjustments.
May require modality-specific HR targets for rowing in older adults; leaves open effects on fitness or adherence.
For older people exercise intensity is often determined based on heart rate (HR) or the percentage of maximal HR (%HRmax). This study evaluated oxygen uptake (O2) and HR during ergometry rowing (combined arm and leg; sitting exercise) and treadmill running (leg; upright exercise) for 15 older people [age, (mean +/- SD) 62 +/- 3 years]. The HR was lower during ergometry rowing than during treadmill running at a blood lactate concentration of 4 mmol l-1 (151 +/- 4 beat min-1 versus 160 +/- 5 beat min-1, P<0.05) and at a maximal effort (171 +/- 7 beat min-1 versus 177 +/- 7 beat min-1, P<0.05). This was the case although the O2 was higher during ergometry rowing than during treamill running both at a blood lactate concentration of 4 mmol l-1 (3.0 +/- 0.4 l min-1 versus 2.7 +/- 0.4 l min-1, P<0.05) and at a maximal effort (3.4 +/- 0.4 l min-1 versus 3.1 +/- 0.3 l min-1, P<0.05]. %HRmax and %HR reserve were lower during ergometry rowing than during treadmill running. The results suggest that, in prescription of rowing for older people, the relation between HR and O2 for rowing and the attenuated HR response to rowing should be taken into consideration.

Yoshiga et al. (2003) conducted a cross-sectional in Healthy older men (n=15). Ergometry rowing vs. Treadmill running was evaluated on Heart rate at a blood lactate concentration of 4 mmol/L (p=<0.05). Ergometry rowing elicited a lower heart rate than treadmill running at a blood lactate concentration of 4 mmol/L (151 vs 160 beats/min, P<0.05) and at maximal effort (171 vs 177 beats/min, P<0.05).
