Moderate to strong training in connection with longer lifespan

This research is a memory that small changes in training with at least moderate intensity have to go to really benefit the durability.

The researchers also collected information about smoking status, alcohol consumption, the composition of the diet, the use of hormone therapies, the personal history of cancer or cardiovascular diseases and the family history of myocardial infarction or cancer about self-reports and-if possible-medical records.

The data was analyzed using proportional hazards regression models.

primary result measurements

The primary endpoint of the study was mortality, which was determined using medical records, death certificates or the National Death Index. The participants were enrolled between 2011 and 2015, and mortality was assessed by December 31, 2015. The average follow -up period was 2.3 years.

important knowledge

In the course of the study, 207 of the 16,741 women died in the study. Two models were used to analyze the hazard ratios between activity and mortality: Model 1, adapted to the age and wearing time of the accelerzestometer, and model 2, adapted to potential disruptive factors in connection with lifestyle and personal and family health history.

strong inverse associations have been identified between the overall activity and mortality ( p = 0.002) and MVPA and mortality ( p = 0.0002) with analysis of model 1 and model 2.

between LPA and mortality was an inverse context observed ( p = 0.04), but after adapting to potential disruptive factors in model 2, the association was no longer statistically significant ( p = 0.82). Similarly, a connection between sitting behavior and increased mortality was determined ( p = 0.007), but when adapting to disruptive factors, the statistical significance was lost ( p = 0.99).

The researchers came to the conclusion that physical activity is an advantage for the longevity and that this advantage is largely from MVPA.

practice implications

This research complements the evidence that were used to develop the guidelines for physical activity published by the United States Office of Disease Prevention and Health Promotion (ODPHP). Until recently, the studies that were used to develop these guidelines were based on self -evidence of moderate and intensive physical activity. The emergence of activity measuring devices enables the effects of the effects of easier physical activity as well as a more precise evaluation of moderate and intensive activity.

According to this study, movement seems to help people live longer. Although this data is not exactly earth -shattering, however, more dramatic benefits than previous studies show that a self -report model used for activities (approximately 60 % to 70 % vs. 30 % to 40 % risk reduction when comparing the most active people). the least active). ^{1 It also indicates that easy activity alone is not sufficient to achieve this benefit, and confirms the current guidelines published by ODPHP and the World Health Organization.}

The current guidelines for physical activity recommend adults at least 150 minutes of moderately intensive training or 75 minutes of intensive training per week as well as strength training exercises on 2 or more days a week. The training intensity can be assessed clinically based on the Borg Rating of Perceived Exertion (RPE) scale or the heart rate target zones. ^{4.5 The Borg scale ranges from 0 (lying in bed) to 20 (sprint as soon as possible); Activity with moderate intensity corresponds to 11-14 on the scale, and intensive activity corresponds to 17-19 on the scale. In the heart zone model, moderate training corresponds to 50 % to 70 % of the maximum heart rate and intensive training 70 % to 85 % of the maximum heart rate, whereby the maximum heart rate is valued at 220 minus the age of the person in years.}

According to the National Health Interview Survey (NHIS) of 2016, only 51.7 % of adults in the United States achieve the recommended amount of aerobics exercises. ^{6 Inactivity is an affectable risk factor for morbidity and mortality in chronic diseases, 1 and it receives renewed attention in the Popular culture (e.g. with "Sitting is the new smoking", a sentence that was made popular by Dr. James Levine by Mayo Clinic). In view of the disappointing compliance with the current guidelines, a didactic approach does not seem to be effective for many people. Therefore, it is the responsibility of the providers to adapt and develop alternative strategies for promoting lifestyle changes to those who do not respond to the fact that the current guidelines are simply communicated to them.}

In naturopathy, longer visits and the stronger relationship that you can promote offer a unique advantage in promoting improvements in lifestyle. The concrete use of physical activity for the individual can be discussed in detail, the obstacles to change can be worked out, individual motivations for more movement work out, favorite movements are identified and goals are developed together. Small steps are required for some patients. However, this research is a memory that small changes in training with at least moderate intensity have to go on in order to really benefit the durability. So make a brisk walk.

This study was strengthened by its large sample size and adjustments for disruptive factors. Possible restrictions include a short follow -up time, which cannot rule out an opposite causality, as well as the dependence on self -disclosure for disruptive factors. The decisions of the authors not to provide the details of their research to reproduce or replicate the results is confusing; However, the undisputedness of the results makes a thorough examination of your research methods less necessary.
