Abstract

To elucidate whether physical activity (PA) and sport increase the risk of developing amyotrophic lateral sclerosis (ALS), a literature review of epidemiological studies was conducted according to the Meta-analysis of Observational Studies in Epidemiology guidelines. Six databases (Pubmed, Scopus, ScienceDirect, IngentaConnect, Refdoc and the Cochrane database) were searched to April 2014. Experts were asked to identify studies in press. Studies of interest were examined for their level of evidence and synthetized using Armon's classification for exogenous risk factors for ALS. Of 37 epidemiological works included in the review, two (5.5%) provided class I evidence, and five (13.5%) class II. Others offered evidence of class III (n = 8, 21.6%), IV (n = 16, 43.2%) and V (n = 6, 16.2%). Results were stratified according to type of exposure: (1) PA related to sport and work (n = 14), (2) soccer and American football (n = 9), (3) occupation (n = 12), (4) proxies of PA (n = 2). Among articles which considered "PA related to sport and work", two class I studies and one class II study concluded that PA is not a risk factor for ALS. This evidence establishes (level A) that PA is not a risk factor for ALS. As regards "occupational related activity" a level of evidence of U was obtained (it is unknown whether the professional category "physical worker" is a risk factor for ALS). Football/soccer may be considered as a possible risk factor for ALS (level C) and there is a need for further research taking into account the numerous confounding factors that may arise in this field.

Attention Score in Context

This research output has an Altmetric Attention Score of 14. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 20 July 2018.
All research outputs
#1,092,221
of 13,253,522 outputs
Outputs from European Journal of Epidemiology
#133
of 1,132 outputs
Outputs of similar age
#22,664
of 232,015 outputs
Outputs of similar age from European Journal of Epidemiology
#4
of 20 outputs
Altmetric has tracked 13,253,522 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 91st percentile: it's in the top 10% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 1,132 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 13.3. This one has done well, scoring higher than 88% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 232,015 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 90% of its contemporaries.
We're also able to compare this research output to 20 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 80% of its contemporaries.
