Title: Time Varying Motion and Muscle Activation Patterns During Extreme Conditioning Protocols
Author: DiMonte, Stephen
Abstract: The popularity of Extreme Conditioning Protocols has increased in recent years. However, due to the high intensity and competitiveness, participants are at greater risk of injury. This thesis aims to quantify changes in muscle activation, kinematics, and discomfort of the squat and deadlift exercises during an Extreme Conditioning Protocol.
Twenty participants (minimum of 1 year experience, frequency of 2X/week) performed 5 sets of 8 deadlifts (60% 1RM), 8 front squats (60% 1RM), and 10 shoulder presses (35/25 lbs.). Average whole body kinematics, muscle activation, and discomfort ratings were measured. Significant changes were observed from the 1st round to 5th round in the trunk, hip and knee angles, muscle activation, and discomfort.
Despite using experienced individuals as participants, this research showed their movement patterns were affected by an extreme conditioning protocol performed with minimal rest. Therefore, participants should be conscious of their technique during this type of workout to prevent injury.
