Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

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

This is a prospective, randomised, double-blind, placebo-controlled superiority trial with two parallel groups and a 1:1 allocation ratio investigating the effects of PEMF therapy on athletes. Participants will be recruited from the Physical Education and Sports Science Department at the National Institute of Education, Nanyang Technological University in Singapore. Researchers will monitor sports performance and recovery outcomes during baseline assessment and at the 8- and 12-week follow-ups after the start of Pulsed Electromagnetic Field (PEMF) therapy. The PEMF therapy will last for 8 weeks, with the final assessment scheduled at week 12. The outcomes measured at 8 weeks will reflect the short-term effects, while the final time point may indicate the carry-over effects of PEMF therapy on athletes.

The PEMF therapy will be administered using a commercial device (QuantumTX Pte). The delivery of PEMF to the leg will not produce heat or cause any sensation, which allows the participants to be blinded to the treatment. Participants in the control group will receive sham exposure with the same PEMF device. Each leg will undergo either active PEMF therapy or sham PEMF therapy for 10 minutes per session, with the treatment administered twice weekly for 8 weeks, resulting in a total of 16 sessions. The PEMF device will be activated by the Radiofrequency Identification (RFID) card, which will be coded to deliver either the active or sham PEMF treatment. The PEMF therapy procedure will be as follows: The participant will be seated in a 90° position on a chair, and the entire quadriceps muscle will be placed within the solenoids of the PEMF device. When active, the device delivered uniform 1.2 mT, 50 Hz PEMFs to each quadriceps muscle for 10 minutes.

Study Groups

Active PEMF Group

The active PEMF group will receive 8 weeks of active pulsed electromagnetic field therapy.

Group Type EXPERIMENTAL

Active Pulsed Electromagnetic Field Therapy

Intervention Type DEVICE

The 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 PEMF Group

The sham PEMF group will receive 8 weeks of sham pulsed electromagnetic field therapy.

Group Type SHAM_COMPARATOR

Sham Pulsed Electromagnetic Field Therapy

Intervention Type DEVICE

The 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.
