Assessment of Peak Oxygen Uptake with a Smartwatch and its Usefulness for Training of Runners

Int J Sports Med DOI: 10.1055/a-1686-9068Peak oxygen uptake (˙VO2peak) is an important factor
contributing to running performance. Wearable technology may allow the
assessment of ˙VO2peak more frequently and on a larger scale.
We aim to i) validate the ˙VO2peak assessed by a smartwatch
(Garmin Forerunner 245), and ii) discuss how this parameter may assist to
evaluate and guide training procedures. A total of 23 runners (12 female, 11
male; ˙VO2peak:
48.6±6.8 ml∙min−1∙kg−1)
visited the laboratory twice to determine their ˙VO2peak
during a treadmill ramp test. Between laboratory visits, participants wore a
smartwatch and performed three outdoor runs to obtain
˙VO2peak values provided by the smartwatch. The
˙VO2peak obtained by the criterion measure ranged from 38
to
61 ml∙min−1∙kg−1.
The mean absolute percentage error (MAPE) between the smartwatch and the
criterion ˙VO2peak was 5.7%. The criterion measure
revealed a coefficient of variation of 4.0% over the VO2peak range from
38–61 ml∙min−1∙kg−1.
MAPE between the smartwatch and criterion measure was 7.1, 4.1 and
−6.2% when analyzing ˙VO2peak ranging from
39–45 ml∙min−1∙kg−1,
45–55 ml∙min−1∙kg−1
or
55–61 ml...
