a
Blood pressure calculated using 39 participants as data were missing for 6 participants.
b
Heart rate calculated using 44 participants as data were missing for 1 participant.
c
Self-reported using Borg scale: 6 (no exertion) – 20 (maximal exertion).
SD: standard deviation; BMI: body mass index; SBP: systolic blood pressure; DBP: diastolic blood pressure; HR: heart rate.
