Abstract

Background Physical exercise is beneficial to reduce the risk of several conditions associated with advanced age, but to our knowledge, no previous study has examined the association of long-term exercise interventions (≥ 1 year) with the occurrence of dropouts due to health issues and mortality, or the effectiveness of physical exercise versus usual primary care interventions on health-related outcomes in older adults (≥ 65 years old).Objective To analyze the safety and effectiveness of long-term exercise interventions in older adults.Methods We conducted a systematic review with meta-analysis examining the association of long-term exercise interventions (≥ 1 year) with dropouts from the corresponding study due to health issues and mortality (primary endpoint), and the effects of these interventions on health-related outcomes (falls and fall-associated injuries, fractures, physical function, quality of life, and cognition) (secondary endpoints).Results Ninety-three RCTs and six secondary studies met the inclusion criteria and were included in the analyses (n = 28,523 participants, mean age 74.2 years). No differences were found between the exercise and control groups for the risk of dropouts due to health issues (RR = 1.05, 95% CI 0.95-1.17) or mortality (RR = 0.93, 95% CI 0.83-1.04), although a lower mortality risk was observed in the former group when separately analyzing clinical populations (RR = 0.67, 95% CI 0.48-0.95). Exercise significantly reduced the number of falls and fall-associated injuries, and improved physical function and cognition. These results seemed independent of participants' baseline characteristics (age, physical function, and cognitive status) and exercise frequency.Conclusions Long-term exercise training does not overall influence the risk of dropouts due to health issues or mortality in older adults, and results in a reduced mortality risk in clinical populations. Moreover, exercise reduces the number of falls and fall-associated injuries, and improves physical function and cognition in this population.

  • The type and frequency of exercise (PRT, aerobic MICT, or HIIT) and the individual's age, as well as cognitive and physical function levels, do not affect attrition rates owing to medical problems or mortality.

    “The type and frequency of exercise (PRT, aerobic MICT, or HIIT) and the individual's age, as well as cognitive and physical function levels, do not affect attrition rates owing to medical problems or mortality [285].”
  • PRT is safe for older adults, including those who are frail or have multiple chronic conditions.

    “Despite the proven safety of PRT for older adults [108,285,287], including those who are frail [288,289], or have multiple chronic conditions [108], clinicians often hesitate to prescribe this exercise modality [108,285,[287], [288], [289]].”
  • Long-term physical exercise is safe and effective in older adults, and its benefits accrue regardless of age, physical function, or cognitive status at baseline.

    “Therefore, long-term physical exercise is safe and effective in older adults, and its benefits accrue regardless of age, physical function, or cognitive status at baseline [285].”
  • Long-term (> one year) physical exercise interventions have been shown to reduce the risk of falls and improve muscle strength, balance, physical function, and cognition without increasing the risk of health-related dropouts, mortality, or fractures compared to usual care.

    “Long-term (> one year) physical exercise interventions [284,285] have been shown to reduce the risk of falls and improve muscle strength, balance, physical function, and cognition [285] without increasing the risk of health-related dropouts, mortality, or fractures compared to usual care [284,285].”
  • Long-term (> one year) physical exercise interventions have been shown to reduce risk of falls and improve muscle strength, balance, physical function, and cognition without increasing risk of health-related dropouts, mortality, or fractures compared to usual care.

    “Long-term (> one year) physical exercise interventions [284,285] have been shown to reduce the risk of falls and improve muscle strength, balance, physical function, and cognition [285] without increasing the risk of health-related dropouts, mortality, or fractures compared to usual care [284,285].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
