What is the recommended amount of physical activity for adults?
The recommended amount of physical activity by the ACSM is 150 minutes of exercise at moderate intensity per week in 30 minute bouts or it can be broken up into 10 minute sessions throughout the day. It is also beneficial to incorporate 2 sessions of strength training per week that work large/major muscle groups of the body.
What is the screw home mechanism?
The screw home mechanism is a feature of the knee that has to do with the locking mechanism of the knee. This feature is mainly due to the shape of the medial condyle of the Tibia. Due to the shape of the condyle it causes the Tibia to become slightly externally rotated at the knee at the end range of extension. Usually within the last 10 degrees of motion. This is important to help lock the knee when in full extension.
