Regarding the variable muscle stren

Regarding the variable muscle strength, Young et al. (2007) used the squat test and Holmerova et al. (2010) used the chair stand test, achieving important increases in the number of repetitions performed after 12 months and 12 weeks of interven- tion respectively. It seems appropriate to highlightthat despite results obtained, the mean age in the first study (65 years old) was considerably inferior to the mean age (78 years old) in Shigematsu et al. (2002) study, the one in Eyigoret al (2009) (73 years old)or in the study from Holmerova et al. (2010) (79 years old and 81 years old, respectively) on the other hand, the intervention based on dance from Young et al. (2007) study included squatting exercises which could have influenced the increase of lower limb strength Uones et al., 1998).
