Sliding filament theory is the currently accepted mechanism behind how muscles contract. It tells us that muscles shorten or lengthen when the two filaments, known as actin and myosin, slide past each other. The filaments slide instead of changing length, which is what was previously thought. The topic of sliding filament theory is covered in … Read more

The single-leg squat assessment is a transitional movement assessment which looks at neuromuscular control, dynamic flexibility, balance, and core strength. By seeing if the knee turns inward during the squat (knee valgus), you can determine if a person has decreased hip abduction, hip external rotation strength, and limited ankle dorsiflexion.  For anyone prepping for their … Read more

Upper crossed syndrome (UCS) is a postural issue where clients may have a forward head, overextended cervical spine, with rounded shoulders. NASM states that people with upper crossed syndrome may also have thoracic spine kyphosis, raised shoulder or scapular winging. Over time this dysfunction can lead to joint issues and muscle imbalances, so it’s important … Read more

The LPHC, or the lumbo-pelvic-hip complex, is a group of muscles and connective tissues located in the back of the hip joint. These muscles play a crucial role in maintaining stability, balance, balance, and proper movement patterns in the lower body. Understanding and properly training the LPHC can help prevent injuries and improve overall athletic … Read more
