About this trial
The goal of this clinical trial is to learn if pulsed electromagnetic field (PEMF) therapy works to improve sports performance and recovery in athletes. The main questions it aims to answer are:
* Does PEMF therapy enhance participants' performance during exercise? * Does PEMF therapy enhance recovery in participants after exercise? Researchers will compare active PEMF therapy to sham PEMF therapy (using the same device for both, but without any electromagnetic fields) to see if active PEMF therapy is effective in improving sports performance and recovery.
Participants will:
* Receive active pulsed electromagnetic field therapy or sham pulsed electromagnetic field therapy twice a week for 8 weeks. * Visit the laboratory at baseline, 8 weeks, and 12 weeks for sports performance and recovery assessments.

Treatments tested in this trial
Active Pulsed Electromagnetic Field Therapy
DeviceThe experimental group will receive active Pulsed Electromagnetic Field (PEMF) therapy twice weekly for 8 weeks, for a total of 16 sessions. Participants will sit comfortably in a chair with their legs placed inside the solenoid of the PEMF device. The active PEMF settings are 1.2 milliTesla (mT) at 50 Hertz (Hz). Each PEMF session will last 20 minutes, with 10 minutes of active PEMF exposure per leg.
Sham Pulsed Electromagnetic Field Therapy
DeviceThe control group will receive sham Pulsed Electromagnetic Field (PEMF) therapy twice weekly for 8 weeks, for a total of 16 sessions. Participants will sit comfortably in a chair with their legs placed inside the solenoid of the PEMF device. The sham PEMF settings are 0 milliTesla (mT) at 0 Hertz (Hz). Each PEMF session will last 20 minutes, with 10 minutes of sham PEMF exposure per leg.

Trial outcomes
Primary outcomes
1
Wingate anaerobic test rate of fatigue
The Wingate anaerobic test involves a 30-second all-out cycling effort performed while stationary. Participants pedal as fast as possible against a standardised resistance for 30 seconds. The percentage decline in power output is calculated from the peak power to the lowest power during the test. It measures how quickly an individual fatigues during intense anaerobic exercise and their capacity to sustain high power output.
Time frame
From enrollment to the end of treatment at 8 weeks, and a 12-week follow-up2
Blood lactate level
Finger-prick blood sampling for lactate levels will be performed at 4 time points (baseline and 5, 15, and 30 min after the Wingate anaerobic test).
Time frame
From enrollment to the end of treatment at 8 weeks, and a 12-week follow-upSecondary outcomes
1
Wingate anaerobic test peak power
The Wingate anaerobic test involves a 30-second all-out cycling effort performed at a stationary position. Participants will pedal as fast as possible against a standardised resistance for 30 seconds. The highest power output achieved during the 30-second Wingate anaerobic test will be recorded as the peak power in Watts.
Time frame
From enrollment to the end of treatment at 8 weeks, and a 12-week follow-up2
Wingate anaerobic test mean power
The Wingate anaerobic test involves a 30-second all-out cycling effort performed at a stationary position. Participants will pedal as fast as possible against a standardised resistance for 30 seconds. The average power output achieved during the 30-second Wingate anaerobic test will be recorded as the mean power in Watts.
Time frame
From enrollment to the end of treatment at 8 weeks, and a 12-week follow-up3
Skeletal muscle mass
Skeletal muscle mass in kilograms will be assessed using the InBody Body Composition Analyser while standing. Skeletal muscle mass specifically relates to muscles that can grow through training.
Time frame
From enrollment to the end of treatment at 8 weeks, and a 12-week follow-up4
Muscle stiffness
Muscle stiffness of the vastus lateralis will be assessed using the MyotonPRO Digital Palpation Device at rest.
