About

This research is being done to better understand the pulmonary consequences of completing an ultra marathon at altitude and a sea level city.

Full description

Subjects will be asked to undertake three (3) sets of assessments at prescribed time intervals: Baseline (at 72-24h prior to each event), immediately post (within 2h of race completion) and during recovery (within 24-48h of race completion). Each assessment will consist of 1)lung function tests; 2) a saliva and blood sample; 3) a lung and cardiac ultrasound. Subjects will be recruited from a range of age groups and fitness levels, before being divided into a sham or therapy group. Groups will use Pulsed Electromagnetic Field (PEMF) therapy or related sham before the event and during recovery.

72 participants in 4 patient groups

HK100 Pulsed Electromagnetic Field

Experimental group

Description:

20 athletes (ideally a mix of elite and amateur level athletes and veteran (40-65y) and young (20-39y). Athletes will be recruited at the 2018 and 2019 Hong Kong 100 races. In addition, these athletes will use the pulsed electromagnetic field (PEMF) for the two weeks prior to the race.

Treatment:

Procedure: Pulsed Electromagnetic Field therapy (PEMF)

HK100 Pulsed Electromagnetic Field Sham

Sham Comparator group

Description:

20 athletes (ideally a mix of elite and amateur level athletes and veteran (40-65y) and young (20-39y). Athletes will be recruited at the 2018 and 2019 Hong Kong 100 races. In addition, these athletes will use a PEMF device that doesn't produce electromagnetic fields (sham) for the two weeks prior to the race.

Treatment:

Procedure: Pulsed Electromagnetic Field Sham therapy
