Exercises: Abdominals "Crunch"
Good
afternoon, today we leave you a new post in our blog about the benefits of
realizing abdominals exercises in a training.
This is a very simple exercise which we can do at home without any type
of risk injury.
The muscles of the abdominal Wall (rectus abdominu muscle, external
oblique, internal oblique, transversus abdominis muscle) and the Psoas plays an
important role in the correct proper functions of the lumbar rachis. (Juker y
cols., 1998). The stabilizing role of the abdominal musculature, it’s based on
the aptitude to reduce the intradiscal pressure in the rachis lumbar-dorsal. (Anderson
y cols., 1997; Hodges y Richardson, 1999).
The execise
about which we’re going to speak today “Crunch”
it’s an exercise that has demonstrated to be
very suitable and effective for the abdominal musculature, furthermore, it’s very secure for the rachis
lumbar-dorsal (Warden y cols., 1999; Axler y McGill, 1997) for reducing compressing
forces(<2000 N) an the stress of shears (McGill, 1998; 2001; Juker y cols., 1998).
Báñez y cols. (1999) recommend realising this exercise for being more effective in the rectus abdominis muscle activation and so
reduce the factors of risk of the active coxofemoral flexion.
