... and ideally also for other power lifting exercises and a range of different loads.
1. Power Clean
What it is: A movement that lifts a barbell from the floor to the shoulders in one explosive motion.
Key Phases:Setup: Start with the barbell on the floor, feet hip-width apart, back straight, chest up, and hands gripping the bar slightly wider than shoulder-width. First Pull: Lift the bar off the ground by extending your knees and hips while maintaining a straight back. Second Pull: Explosively extend your hips and pull the bar upward, shrugging your shoulders and keeping the bar close to your body. Catch: Drop into a quarter squat and "catch" the barbell on your shoulders, with elbows high. Stand Up: Rise to a standing position with the barbell securely resting on your shoulders.
Purpose: Develops explosive power, coordination, and speed.
2. Hang Clean
What it is: Similar to the power clean, but the movement starts from a "hang" position (with the barbell above the knees) rather than from the floor.
Key Phases:Setup: Stand upright holding the barbell, with the bar just above your knees, feet hip-width apart, and back straight. Load: Slightly bend your knees and push your hips back to prepare for the explosive phase. Second Pull: Drive through your hips, pulling the bar upward while shrugging your shoulders. Catch: Drop under the bar into a quarter squat, catching the barbell on your shoulders. Stand Up: Stand tall to complete the movement.
Purpose: Focuses on the explosive hip extension and is easier to perform repeatedly compared to a power clean.
3. Snatch
What it is: A movement that lifts the barbell from the floor to overhead in one continuous motion.
Key Phases:Setup: Start with a wide grip on the barbell, feet hip-width apart, chest up, and back straight. First Pull: Lift the barbell off the ground by extending your knees while maintaining your posture. Transition: As the bar passes the knees, shift your torso upright and prepare for the explosive pull. Second Pull: Explode through your hips and pull the bar upward, shrugging your shoulders and keeping the bar close to your body. Catch: Drop quickly into an overhead squat while locking the bar overhead, arms fully extended. Stand Up: Rise from the squat position with the bar overhead to complete the lift. Thank you!
The best way to go about this would be to perform a musculoskeletal simulation. It will give you alle the 3D joint moments involved, regardles of whether these are produced by muscles are due to joint constraints. I recommend the AnyBody Modeling System, https://www.anybodytech.com/. Strength training exercises are relatively easy to model with such a system.
Recommeding to look into Functional Anatomy Setups for this movement. checking the shares between the different players of the movement. only then you would be able to understand the Newtons load on each joint part, and why the joints are developed in a way do make that moves happen. Keep in mind that gym movements are frequently not neccessarily natural movements.
