Abstract
We investigated whether an eight week, light resistance program could increase the
muscular strength of the knee and elbow extensors and flexors in a group of hospitalized
anorexic patients compared to anorexic controls (AC) who did not participate in the
training program, but received the same caloric intake, and non-anorexic exercisers
(NAE) who undertook the resistance training program. After the resistance training
program, the seven anorexic exercisers (AE) significantly increased the peak torque
(PT) of their knee extensors (p < 0.001), flexors (p < 0.0001) and elbow flexors (p
< 0.01). In comparison, the seven anorexic non-exercisers (anorexic controls, AC)
and seven non-anorexic exercisers (NAE), who performed the same program, showed no
significant increase in peak torque after the program (p > 0.05). The study has demonstrated
that an eight week, light resistance program increases the knee and elbow strength
of the hospitalized anorexic patients.
Key words
Anorexia nervosa - strength training - peak torque
