Effect of Pulsed Electromagnetic Field Therapy as an Adjunct Modality to Warm-up Exercise

The goal of this clinical trial is to assess the effectiveness of pulsed electromagnetic field therapy as an adjunct to warm-up exercises, in healthy participants. Researchers will investigate both the immediate effect of one round of pulsed electromagnetic field therapy (PEMF) and after a warm-up exercise, on participants' range-of-motion (ROM) at the knee and quadriceps' muscle stiffness, measured through shear wave elastography, an ultrasound technique. This may be useful in future interventions to protect against sports injuries. Participants will have their knee ROM and quadriceps' muscle stiffness measured thrice, once at baseline, once after PEMF/sham treatment, and once after 5 minutes of warm-up stationary bike exercises. Researchers will compare with sham treatment to see if there are any significant effects from PEMF therapy.
