N2 - Aim: To assess muscular fitness by hand grip strength (HGS) and lower limb extension power (LEP) and to explore associations with age, leisure time physical activity (LTPA) and body composition. Study population: A population-based sample of 19-72-year-old men and women were invited to participate in the health survey 'Health2006'. The response rate was 43.8% (N=3471), 55% were women, and the mean age was 49=13 years. Methods: Height, weight, waist circumference, HGS and LEP were measured and participants answered a self-administered questionnaire. LEP was measured in a subsample of subjects (n=438). Gender-stratified multiple linear regression analyses were carried out. Data were adjusted for age, height and waist circumference. Results: A large inter-individual variation was found in HGS and LEP. Both measures declined with age and were highly correlated (r=0.75, p<0.0001). LTPA was positively associated with HGS in men (p=0.0002) and women (p<0.0001) in the total sample, but in the subsample was significant in men only (p=0.004); the association between LTPA and LEP was significant in women only (p=0.02). Conclusion: In this large population-based study sample, muscular fitness declined with age and LTPA was associated with HGS in both genders. The findings emphasise the importance of maintaining a physically active lifestyle at any age.
