Design

COX-proportional hazard analyzes were used prospectively to compare breast cancer mortality with the initial training energy and to determine whether running and going according to the diagnosis differ significantly in connection with breast cancer mortality.

participant

The data used in this analysis come from 272 runners and 714 walkers from the National Runners 'and Walkers' Health Studies, in which breast cancer was previously diagnosed. The diagnosis was made (average ± standard deviation) 7.9 ± 7.3 years before the start of the course. 46 women (13 runners and 33 belongs) died during the 9.1-year-old mortality monitoring of breast cancer.

study medication and dosage

The metabolic equivalents (METS) per hour and day were calculated on the basis of survey data.

target parameter

breast cancer -related mortality

most important knowledge

When the data and walkers have been evaluated together, the breast cancer death risk decreased by an average of 24 % per meter hour per training day, with 1 MET hour a little less than a mile walking or about two thirds of which corresponds to a mile.
The possibility that such a simple intervention in the long term will prove to be useful is certainly fascinating.
When the runners and walkers are separated, there was a significantly lower mortality rate among the runners. The risk of the runners to die from breast cancer decreased by over 40 %per meter lesson and day. Runners who laid average more than 2.25 miles per day had a 95 % lower risk of dying from breast cancer than runners who did not adhere to the current training recommendations. In contrast, hikers' breast cancer risk fell by a significant 5 % per meter lesson and day.

effects on practice

For half a dozen years, we have expressly encouraged breast cancer patients to go consistently almost every day, based on data from Irwin et al., which suggested that the mortality rate be reduced by 45 %. Based on this new article by Williams, it seems that we should encourage more intensive training - actually run, with an optimal distance of 2.25 miles per day.
Almost a quarter of women in which invasive breast cancer was diagnosed, die within 15 years after the diagnosis.
physical activity can improve the survival of women with breast cancer, but the evidence of this is mixed. Numerous other studies have already shown that physical activity significantly reduces breast cancer mortality. 1.3-7 Several other studies have not demonstrated significant reduction. 8-12 If data is combined via meta-analyzes, there is stronger indications of an improved survival rate with larger physical activity. For example, data from 13:302 Breast Cancer survivors of the After Breast Cancer Pooling Project indicate that compliance with current recommendations for physical activity is connected to a reduction in breast cancer mortality by 25 %.
All healthy adults aged 18 to 65 years aerobic (endurance) of medium intensity or at least 20 minutes a week aerobic activity of high intensity.
Two other meta -analyzes came to similar conclusions. Patterson et al. Fixed a reduction of 29 % (including measuring physical activity throughout life and diagnosis). Found a reduction by 34 % 16 in breast cancer mortality with physical activity after diagnosis when different study results were combined.
There are aspects of this study that are criticized - in particular the self -reporting on the activity of the participants, the lack of information about the cancer stage in diagnosis, the type of breast cancer of the participants and what treatment (s) have undergone women.
In women who were diagnosed with breast cancer, there is a slight risk of damage through the promotion of more physical activity and higher training intensity. The possibility that such a simple intervention will prove to be useful in the long run is certainly fascinating. Now, at least at the moment, we have reason to encourage these patients to run.
