Achilles tendinopathy (AT) is a condition resulting in foot and ankle pain, accounting for 8-15% of all injuries in recreational runners (1-3). While previous studies have demonstrated a relationship between individuals with AT and a significant reduction in amplitude of gluteus medius (GMED) activity after heel strike, hip muscle activation timing patterns have not been studied (4). This 2014 study by U.S. researchers demonstrated a correlation between delayed, shorter duration activity of the gluteus maximus (GMAX) and GMED in runners with AT. Human movement professionals should consider assessing GMAX and GMED strength/re-activity, and address any noted weaknesses in those exhibiting signs of AT.
