Meta-analysis: optimal taper for performance

Astrong evidenceMeasured on trained to elite athletesWritten before October 2026, being re-checked

Key Findings

Meta-analysis of 27 studies (of 182 screened) in competitive athletes; outcome = actual competition or field-based criterion performance, pre-post taper standardized mean differences.

Practical Conclusion

Volume = key taper variable. Reduce volume 41-60% exponentially over 2 weeks, PRESERVE intensity and frequency.

Practical Application

Meta-analysis of 27 taper studies in competitive athletes: the most efficient taper is 2 weeks long with training volume reduced exponentially by 41-60% (effect 0.72 ± 0.36), while training intensity and frequency are left unchanged — cut the hours, keep the hard sessions and the number of sessions.
Do not lower intensity or drop sessions in the taper: in the pooled data, tapers that kept intensity (0.33 ± 0.14) and frequency (0.35 ± 0.17) unmodified were the ones that worked; the abstract does not support "easing off everything".
"Exponential" is the taper shape in the pooled optimum: volume decays progressively across the 2 weeks rather than dropping in a single step and staying flat.
Inference, not tested: the 2-week optimum is a group mean across sports; how long a given athlete needs depends on prior load and individual response (see REF-108).

Limitations

2007 meta-analysis of 27 studies — heterogeneous sports, tapers and performance tests pooled into single recommendations.
Participants are "competitive athletes" by inclusion criterion; the abstract gives no tier breakdown, so the optimal taper for a Tier 4-5 athlete is extrapolated from a mixed pool.
The pooled optima (volume cut, duration, intensity maintenance) are group means; individual taper response varies enough that REF-108 exists to address it.
Publication bias is likely: a taper study finding no benefit is less likely to be published or included.
Nothing here covers repeated tapers within a season, or tapering into a stage race rather than a single event.

Application block "first taper week −30% volume, 100% intensity — 1 week" and "final week −50-60% volume, maintain 2-3 HIT sessions" -> deleted; house schedule, not in the abstract (which gives one 2-week exponential 41-60% taper).
"Mujika & Padilla 2003: 2-week taper risks detraining → 1+1 strategy" -> deleted; not from this paper and no refId in the base carries it.
Lead bullet now states the pooled finding (2 wk, exponential −41-60%, intensity and frequency unchanged) with its effect sizes; "Maintain 100%" -> "Maintain (no modification)".
