Effets de la reprise d’une activité physique régulière sur les capacités physiques et la qualité de vie d’hommes atteints du syndrome métabolique

Objective

To assess the effects of aerobic training on physical capacities and quality of life in men with metabolic syndrome (Mets), using field evaluation tools.

Synthesis

The physical capacities and the quality of life of eight men with Mets (59.5 ± 4.8 years old) was assessed before and after 8 weeks of aerobic exercise training by the 6 minutes walking test and the quality of life, obesity and dietetics scale.

Conclusion

Aerobic exercise training of 8 weeks improves physical capacities and the psychosocial impact dimension of quality of life in men with Mets, without generating anthropometric modification.     

Validité et reproductibilité d’un dynamomètre inertiel basé sur l’accélérométrie

Introduction

The purpose of this study was to investigate the validity and reliability of an inertial dynamometer using accelerometry.

Methods

Fourteen subjects were tested during three successive sessions at four increasing loads (30, 50, 70 and 95% of the 1RM). Maximal force, velocity and power performances were simultaneously assessed by the Myotest (Myotest S.A., Switzerland), an inertial dynamometer using accelerometry, and by another control valid dynamometer witch combine accelerometer and linear position transducer. At three first loads, only minor differences appeared in between both dynamometers, correlations were excellent and coefficients of variation were good and similar. However, at 95% of the 1RM, Myotest validity and reliability became insufficient.

Conclusion

Bench press inertial assessment with accelerometer appeared valid and reliable at 30, 50 and 70% of the 1RM, but not at 95% of the 1RM.
