Squatting with feet inside the pelvis, i.e., ‘ankle squats’; with shins tilting forward as much as possible (see figure and video); strengthens the calf musculature, especially soleus; by a process called reverse – origin – insertion – contraction. The soleus muscle is lengthened under tension; as the shins tilt forward. Subsequently, these muscles pull the shins backwards as they contract. Returning the shins from the tilted disposition acts to straighten knee and hip; as all links are interconnected through ankle, knee and hip joints.
researchers of injury susceptibility of the female athlete in sport focus on the preposterous premise of altering unalterable inherent traits: undulating fluctuation of hormones, mobility of joints, inherent skeletal features, extensibility of ligaments, and so forth, i.e., drawing lines, nature itself refused to draw.
three aspects of exercise protocols stemming from instructions of conditioning coaches, therapists, personal trainers, academics, doctors and so forth; serve to show how unanticipated outcomes arise from inconsequential thinking. The following types of constraints: motor task, instructional and intentional; as defined by Latash and Zatsiorsky, 2016; are concepts whether consciously or unconsciously, are abused on a regular basis by conditioning coaches, various exercise hucksters, charlatans of misinformation, academics, therapists and others.
The basic premise of this exercise: one is to learn the necessary height of lifting in the pull to lift a maximum weight in the classic exercise. The height of lifting needed to fix a weight in either the snatch or the clean is determined for a given athlete. For instance, this was considered to be about sternum height for the snatch.
there is little if anything in the literature concerning the affect of barbell oscillation/vibration on the weightlifter’s physiology; likewise, the skill to coordinate release of elastic energies from the barbell’s elastic recoil with those energies from the weightlifter’s bio – springs. The effects of barbell vibration/oscillation and deflection (bend) on weightlifting technique involves physics, physiology and the weightlifter’s skill to coordinate the two: the physics with physiology.
