Intense physical activity can greatly reduce cardiac risk

Knowledge

  • Moderate to vigorous physical activity (MVPA) is particularly effective in reducing the risk of cardiovascular disease (CVUs) through physical activity energy expenditure (PAEE).
  • MVPA as a disproportionate component of PAEE may be a more effective way to mitigate risk than simply increasing the -_ PAEE.

Why this is important

  • How intensity and extent of physical activity (PA) are related to KVE risk prevention is not fully understood.
  • This study avoided the determination of PAs by self-reporting through the use of a monitoring device.
  • The results suggest that there are a variety of flexible sports measures to choose from for each person.

Study design

  • Analysis of population-based prospective UK&nbsp data; Biobank (n = 88.412)
  • Participants wore 7  An accelerometer for days.
  • The authors used these data to determine the PA, including the proportion of the PA that was MVPA.
  • Result: Emerging KVE incidents
  • Funding: Funding by authors

Key results

  • Average age: 62  Years
  • Median follow-up: 6.8  years
  • After adjusting for confounding factors, lower KVE rates correlated with:
    • more PA and with
    • a higher proportion of MVPA.
  • At the same level of PAEE, the KVE risk decreased by  14 % when the proportion of MVPA increased from  10 % to  20 %.
  • This equates to a 7-minute quick walk instead of a 14-minute slow walk.
  • Both activities result in the same PAEE, but the quick walk is more intense and associated with lower KVE rates.
  • more PA and with
  • a higher proportion of MVPA.

Restrictions

  • Accelerometers are not the right tools to determine training intensity during stationary activities such as weightlifting.
  • May not generalizable to other populations
