Résumé
Progressive ageing of the population has highlighted the importance of the relationship between physical function and frailty in patients with chronic disease. The aim of this study was to assess the association between exercise capacity and grip strength (GS) in a cohort of older patients involved in an exercise-based secondary prevention program. Sixty-five outpatients (aged 75±6 years) were included. Exercise capacity was assessed through the estimation of maximal oxygen consumption (V̇O<inf>2peak</inf>) and the measurement of walking speed (WS). GS was evaluated in the dominant arm using a hand-held dynamometer. Patients with higher V̇O<inf>2peak</inf> and WS values exhibited significantly higher GS (P<0.01). GS was significantly related to WS (P<0.01) and V̇O<inf>2peak</inf> (P<0.01), and inversely associated with age (P<0.01). Results from linear multiple regression analysis (P<0.01) demonstrate that GS was strongly associated with WS (P<0.01) and age (P=0.01), while BMI, weekly LTPA, cardiovascular diagnosis, V̇O<inf>2peak</inf> and education were not. The evaluation of WS, V̇O<inf>2peak</inf> and GS was feasible and well tolerated. These preliminary results suggest that prescribing regular walking activity, educating subjects to perform it at higher average WS, can help to maintain physical function in older patients with cardiovascular disease.

BACKGROUND
BACKGROUND
Progressive ageing of the population has highlighted the importance of the relationship between physical function and frailty in patients with chronic disease. The aim of this study was to assess the association between exercise capacity and grip strength (GS) in a cohort of older patients involved in an exercise-based secondary prevention program.
METHODS
METHODS
Sixty-five outpatients (aged 75±6 years) were included. Exercise capacity was assessed through the estimation of maximal oxygen consumption (V̇O<inf>2peak</inf>) and the measurement of walking speed (WS). GS was evaluated in the dominant arm using a hand-held dynamometer.
RESULTS
RESULTS
Patients with higher V̇O<inf>2peak</inf> and WS values exhibited significantly higher GS (P<0.01). GS was significantly related to WS (P<0.01) and V̇O<inf>2peak</inf> (P<0.01), and inversely associated with age (P<0.01). Results from linear multiple regression analysis (P<0.01) demonstrate that GS was strongly associated with WS (P<0.01) and age (P=0.01), while BMI, weekly LTPA, cardiovascular diagnosis, V̇O<inf>2peak</inf> and education were not.
CONCLUSIONS
CONCLUSIONS
The evaluation of WS, V̇O<inf>2peak</inf> and GS was feasible and well tolerated. These preliminary results suggest that prescribing regular walking activity, educating subjects to perform it at higher average WS, can help to maintain physical function in older patients with cardiovascular disease.
