Effects of Magnesium Oil Application on the Muscle Contractile Properties

Aim: This study will aim to investigate the effects of magnesium oil administration on skeletal muscle contractile properties (SMcp). Design: Randomized controlled study Participants: For this purpose, investigators will recruit 40 recreationally active and healthy adults of both sexes (18-35 years of age). Methods: The experimental leg (EXP) will receive the 10 sprays of magnesium oil (20 mg per spray) that will be topically applied to the skin covering the knee extensor muscles, whereas the control leg (CON) will receive 10 sprays of natural mineral-free oil. The vastus lateralis SMcp will be measured by using a tensiomyography (TMG) device before application (PRE) and after 10 (POST10), 20 (POST20), 30 (POST30), 40 (POST40), and 50 (POST50) minutes of application onset, respectively.
