Abstract

A randomized, double-blind, placebo-controlled study was conducted to evaluate if Lactobacillus helveticus Lafti L10 (Lallemand Health Solutions, Montreal, Que., Canada) supplementation during 14 weeks in winter can influence the duration, severity, and incidence of upper respiratory tract illness (URTI), as well as to monitor different immune parameters in the population of elite athletes. Before and after the treatment, cardiopulmonary testing and self-rated state of moods evaluation (by Profile of Mood States questionnaire) were performed and blood samples were collected. Thirty-nine elite athletes were randomized either to the placebo (n = 19) or the probiotic (n = 20) group. The probiotic group received L. helveticus Lafti L10, 2 × 10(10) Colony Forming Units. Lafti L10 significantly shortened the URTI episode duration (7.25 ± 2.90 vs. 10.64 ± 4.67 days, p = 0.047) and decreased the number of symptoms in the probiotic group (4.92 ± 1.96 vs. 6.91 ± 1.22, p = 0.035). Severity and incidence of URTI did not differ between the treatments. There were no significant changes in leukocyte subpopulation abundance, transforming growth factor-β serum levels, level of interleukin-10 secreted from peptidoglican stimulated peripheral blood mononuclear cells (PBMCs), interferon-γ level secreted from concanavalin A-stimulated PBMCs or viability/proliferation of PBMCs upon antigen stimulation. Group effect for CD4+/CD8+ ratio was significant (F[1,37] = 6.99, p = 0.020, η(2) = 0.350); this difference was not significant at baseline, but was evident after 14 weeks (p = 0.02). A significant interaction effect was noted for self-rated sense of vigor (F[1,37] = 11.76, p = 0.009, η(2) = 0.595). Self-rated sense of vigor increased in the probiotic group (18.5 ± 4.1 vs. 21.0 ± 2.6, p = 0.012). Probiotic strain Lafti L10 can be a beneficial nutritional supplement for the reduction of URTI length in elite athletes.

Attention Score in Context

This research output has an Altmetric Attention Score of 37. 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 08 July 2019.
All research outputs
#866,657
of 21,592,997 outputs
Outputs from Applied Physiology, Nutrition, and Metabolism
#171
of 1,964 outputs
Outputs of similar age
#16,590
of 281,108 outputs
Outputs of similar age from Applied Physiology, Nutrition, and Metabolism
#13
of 62 outputs
Altmetric has tracked 21,592,997 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 95th percentile: it's in the top 5% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 1,964 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 14.9. This one has done particularly well, scoring higher than 91% 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 281,108 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 94% of its contemporaries.
We're also able to compare this research output to 62 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.
