Reported findings and study design
The paper reports 26% fewer shooting misses in the Cortexin arm after ten days, 5.6% faster course speed and a 5.5% versus 2.9% increase in an integrated work-capacity score.
Author-described double-blind comparison of 10 Cortexin and 10 placebo athletes during a 10 km biathlon race with four shooting stages.
Protocol information
The article describes a course of intranasal Cortexin and results after ten days. Dose and allocation details are unverified for this report.
Protocol source ↗ · Original journal article, methods and results
| Measure | Result | Comparison, timing and statistics |
|---|---|---|
| Shooting misses and time | 26% fewer misses and 2.5 s less total shooting time | Reported in the Cortexin arm after ten days. The 26% result also appears in the related patent trail. |
| Speed across the 10 km race | +5.6% in the Cortexin arm | The authors describe the increase as 2.6% better than the comparator’s result. |
| Integrated work-capacity score | +5.5% Cortexin versus +2.9% placebo | The paper cites RU2469730C2 alongside the result. |
| Moving-target reaction accuracy | 1.6-fold versus placebo | Reported p<0.05. The paper cites RU2469730C2 alongside the result. |
| Physiology and safety reporting | Systolic blood pressure rose and heart rate rose slightly in the Cortexin group | No numerical blood pressure or heart-rate values or systematic adverse-event table were supplied in the checked article. |
The 20 reported participants are held out of the archive tally pending cohort matching.

Methods, limitations & source review
Study limitations
- The article cites RU2469730C2 and repeats its 26% shooting result. Its relationship to the 2011 paper and 2012 congress cohort remains unresolved.
- The 127 vs 53 s race-time result attributed to the 2011 paper in a later review is a separate source claim.
Publication counts are not counts of independent trials. Reviews, translations and reports sharing participants may overlap. Findings apply to the studied preparation, population and endpoints.
