The subjects wore a heart-rate meter during the entire duration of the assessment.
The experimental protocol consists of the collection of the heart rate beat to beat and RR intervals (RRi) (in milliseconds) using a cardiac rate meter (Polar-Vantage).
Measuring recovery HR may also provide a more reliable measurement than submaximal heart rate as HR-meters may lose contact for periods during exercise.
A power meter records a rider's heart rate, his pedal cadence, his speed, and, most important, the watts that he generates with every turn of the wheels.
Physical activity patterns can be determined in a number of ways, including direct calorimetry, ingestion of doubly labeled water, and use of motion sensors, accelerometers, heart rate monitors, or oxygen consumption meters, as well as direct observation of gross movements by a trained observer or assessment of food intake.
Heart rate was monitored on line with a rate meter coupled to the blood pressure recorder sensing the arterial pressure oscillations and recorded on a Grass polygraph.
A considerable fraction use wearables (42%) including wrist-worn units [ 31, 41- 45], an electronic vest [ 46], an electronic glove [ 38] as well as mobile medical devices, such as a blood glucose meter [ 22], blood pressure meter [ 47], spirometer [ 48], asthma peak flow meter [ 49], electrocardiogram (ECG) or heart rate monitors [ 24, 28, 50], or multi-purpose meters [ 30, 51, 52].
Heart rate was monitored using a pulse meter (Polar Accurex Plus, Kempele, Finland).
Measure your base heart rate.
The air quality meter, combined with the body fat and heart rate measurement are the big selling points here, since they provide the reasons to spend $50 more vs. the standard WS-30 Withings wireless scale.
