TI  - Effects of a Long-Term Physical Activity Program on Activity Patterns in Older 
      Adults.

AB  - PURPOSE: To examine the effect of a long-term structured physical activity (PA) 
      intervention on accelerometer-derived metrics of activity pattern changes in 
      mobility-impaired older adults. METHODS: Participants were randomized to either a 
      PA or health education (HE) program. The PA intervention included a walking 
      regimen with strength, flexibility, and balance training. The HE program featured 
      health-related discussions and a brief upper body stretching routine. 
      Participants (n = 1341) wore a hip-worn accelerometer for >/=10 h.d for >/=3 d at 
      baseline and again at 6, 12, and 24 months postrandomization. Total PA 
      (TPA)-defined as movements registering 100+ counts per minute-was segmented into 
      the following intensities: low-light PA (LLPA; 100-759 counts per minute), high 
      light PA (HLPA; 760-1040 counts per minute), low moderate PA (LMPA; 1041-2019 
      counts per minute), and high moderate and greater PA (HMPA; 2020+ counts per 
      minute). Patterns of activity were characterized as bouts (defined as the 
      consecutive minutes within an intensity). RESULTS: Across groups, TPA decreased 
      an average of 74 min.wk annually. The PA intervention attenuated this effect (PA 
      = -68 vs HE: -112 min.wk, P = 0.002). This attenuation shifted TPA composition by 
      increasing time in LLPA (10+ bouts increased 6 min.wk), HLPA (1+, 2+, 5+, and 10+ 
      bouts increased 6, 3, 2, and 1 min.wk, respectively), LMPA (1+, 2+, 5+, and 10+ 
      bouts increased: 19, 17,16, and 8 min.wk, respectively), and HMPA (1+, 2+, 5+, 
      and 10+ bouts increased 23, 21, 17, and 14 min.wk, respectively). CONCLUSIONS: 
      The PA intervention increased PA by shifting the composition of activity toward 
      higher-intensity activity in longer-duration bouts. However, a long-term 
      structured PA intervention did not completely eliminate overall declines in total 
      daily activity experienced by mobility-impaired older adults.
