Ethics approval and consent to participate
: Ethics approval for this protocol was sought from the NHS NRES Committee South West (Frenchay) under reference number 15/SW/0007. A favourable opinion was granted on February 9, 2015. The protocol was subsequently amended prior to recruitment in order to incorporate the submaximal exercise test for the purposes of calibrating the ActiheartSuperscript removed monitors. This was approved by the same ethics board as a substantial amendment to the previous reference, which received approval on June 8, 2015. Participants are guided through the informed consent process by the research team prior to any data collection activities. At all times during the study their participation remains voluntary and they are free to withdraw at any time.
