is not defined, therefore, when using the metabolic rate as
an indicator of workload, a participant’s age, overall health,
and lifestyle style choices must also be considered alongside
the HR and TC of the participant.
The data obtained from the gas detector, worn by
the trainer, indicated that the sensor operated with
real-time precision and accurately discerned the correct
gases (Figure 9).
Low oxygen (O2) levels and elevated carbon monox-
ide (CO) levels were detected outside of the normal con-
centration levels. Low concentrations of hydrogen sulfide
(H2S), and ammonia (NH3) were detected, however, both
chemical concentrations were within the safe limits with no
