Angle of attack versus the Coefficient of the Lift – Examining the Pull from an Aviation Standpoint

 

Where is the critical angle of attack during the pull of any Olympic or bodyweight lift? I have observed a stall speed from the concentric phase (the angle of attack), which causes the movement to become difficult unless the stall speed is matched with effective aerodynamics and joint angles of the movement. The greatest part of the lift is produced when the critical angle of attack is reached, which in aviation is called the “burble point”. Side note: which can be applied to strength and conditioning concepts? Also taken into consideration are accelerated and unaccelerated stall speeds, which can become sloppy, which compares to the lack of power and speed, which should complement the concentric phase-speed of the movement and the efficiency of the lift.

So as we observe from the graph below; an aviation standpoint (1st graph), we see the angle of attack versus the coefficient of the lift, meaning the athlete has to have proper technique, no fault in the movement, which in turn will allow an flawless thrust of the weight (more specifically during the concentric phase of the lift) to overcome stalling (inertia) and produce a significant separation, which is produced from an immaculate production of the athletes mass to weight ratio, load factor, bank angle, center of gravity, as well as other factors. As we compare the various factors from the first to second graph, we can form a biased conclusion that the athletes classification (lifting age) does make a difference when making sure the angle of attack matches the coefficient of the lift when putting all the pieces together – force * time = maximum strength, which results in a powerful explosive movement.

Just thinking, turned into a random thought and blog post that will make others think!
