Arthur a toujours raison quand il s'agit de mécanique et de physiologie il peut se tromper sur l'entrainement ou des choses non mesurables. Mais quand tu crées les meilleurs machines du monde, tu t'y connais un peu en mécanique biomécanique et physiologie nothing esle is even possible !!
Nonetheless, squatting has continued to have a stain on its character, although its bad reputation has faded gradually thanks to studies like the one carried out at the University of Alabama. In that work, the knees of 100 male and female college students were measured for stability using a knee ligament arthrometer during nine different tests ('The effect of the squat exercise on knee stability', Medicine and Science in Sports and Exercise, Volume 21 (3), pp. 299-303, 1989). Over an eight-week training programme, individuals who carried out various squatting exercises did not develop reduced knee stability, compared to non-squatting controls. To assess the effects of longer-term squat training, the researchers examined 27 male powerlifters (14 of whom were rated elite or master class) and 28 male weightlifters (eight of whom were elite or master class) using the same tests. As it turned out, the knees of powerlifters and weightlifters were actually significantly LESS lax than those of control individuals during tests of knee-joint flexibility. When the data on powerlifters and weightlifters were also analyzed according to years of experience and skill level, no negative effect of squat training on knee stability was demonstrated in either of the groups tested.
Recent research carried out at the American Sports Medicine Institute in Birmingham, Alabama supports the idea that squatting is not only relatively safe for the knees but also can be superior to open-chain exercise for improving knee stability and strength ('Biomechanics of the knee during closed kinetic chain and open kinetic chain exercises, Medicine and Science in Sports and Exercise, vol. 30-4 (April), pp. 556-569, 1998).
etc etc etc
le SQT ou F-SQT sont safe pour les genoux SI bien faits et aident meme à renforcer les genoux !
EDIT un MODO pour splitter tout ca ? sinon Flash va pas etre content
