      Performance in Older People.

AB  - BACKGROUND: Functional mobility and muscle strength are well known risk factors 
      for sarcopenia. Furthermore, possible associations have been suggested between 
      predisposing factors of sarcopenia and reaction time among the elderly. This 
      study aims to analyze possible associations of functional mobility and muscle 
      strength and reaction times in a population of people aged >60 years. METHODS: A 
      total of 290 older people (69.35 +/- 5.55 years) participated in this study. The 
      following parameters were assessed: optoacoustic lower-limb reaction time 
      (OALLRT); acoustic lower-limb reaction time (ALLRT); optic lower-limb reaction 
      time (OLLRT, using an optical detection system), functional mobility (through the 
      timed up-and-go test) and muscle strength (using a dynamometer). RESULTS: Our 
      results show that lower values of muscle strength were associated with increased 
      reaction times in OALLRT (beta = -0.170; 95% confidence interval -0.011-0.000; R(2) 
      = 0.237; p = 0.035) and in ALLRT (beta = -0.228; 95% confidence interval 
      -0.011-0.002; R(2) = 0.199; p = 0.006). CONCLUSION: Increased muscle strength 
      (which at low values are risk factors for sarcopenia) was associated with 
      decreased reaction times in people >60 years of age.
