Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

HK100 Pulsed Electromagnetic Field

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.

Group Type EXPERIMENTAL

Pulsed Electromagnetic Field therapy (PEMF)

Intervention Type PROCEDURE

PEMF Therapy based on Biological Electromagnetic (BEM) microbial wave technology provides micro-magnetic emissions to the center of the palm (Laogong acupoint). While participating in the study, the subjects will undertake 2 sessions of therapy every day (1 session in the morning and evening). Each session will last for 16-min (8-min for left and 8-min for right hand).

HK100 Pulsed Electromagnetic Field Sham

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.

Group Type SHAM_COMPARATOR

Pulsed Electromagnetic Field Sham therapy

Intervention Type PROCEDURE

PEMF therapy will be administered however it will not produce micro-magnetic emissions. The therapy will be used on the center of the palm (Laogong acupoint) of each hand. While participating in the study, the subjects will undertake 2 sessions of therapy every day (1 session in the morning and evening). Each session will last for 16-min (8-min for left and 8-min for right hand).

UTMB Pulsed Electromagnetic Field

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 Ultra Trail du Mont Blanc (UTMB) races. In addition, these athletes will use the pulsed electromagnetic field (PEMF) for the two weeks prior to the race.
