How to use this page
This note summarizes one study record. Check the participants, methods, results, and limitations before applying it to training.
- • Design signal: review.
- • Population relevance: athlete/trained context.
- • Consistency: single-study evidence.
- • Practical recommendation depends on tolerance, context, and whether it protects training consistency.
ELI5
In plain language
Dividing training objectives into consecutive phases to gain morphological adaptations (hypertrophy phase) and neural adaptations (strength and power phases) is called strength-power periodization (SPP). (review; elite athletes).
In this review, the abstract is mixed or unclear for Time-trial performance. Treat this as a signal, not a guarantee; confirm methods and context in the full paper.
Takeaways
What the abstract suggests
- • Study question: Dividing training objectives into consecutive phases to gain morphological adaptations (hypertrophy phase) and neural adaptations (strength and power phases) is called strength-power periodization (SPP).
- • In this review, the abstract is mixed or unclear for Time-trial performance.
- • Population: elite athletes.
- • Protocol cues (title/abstract): 2 days • 72 h • 148 h • 3 h.
Protocol
Protocol (as reported)
- • Intervention/exposure: taper, tapering.
- • Dose/time/duration cues in abstract/title: 2 days • 72 h • 148 h • 3 h.
- • Outcomes: Time-trial performance.
- • Replication note: abstracts often omit adherence and timing; confirm details before changing training or supplementation.
Fit
Who it may help, and who should be cautious
Who it helps
- • Athletes similar to the study population (elite athletes) working on tapering.
- • Athletes who can measure Time-trial performance with a repeatable workout or time-trial effort.
Who should be cautious
- • If you have symptoms or conditions that make the intervention risky, get professional guidance.
- • If you’re near race day and can’t safely test, defer the experiment.
Methods
What the study actually did
- • Design: review.
- • Population: elite athletes.
- • Outcomes measured: Time-trial performance.
- • Protocol cues mentioned: 2 days • 72 h • 148 h • 3 h.
- • Source: PubMed PMID 26133514 (2015) — Sports medicine (Auckland, N.Z.).
Results excerpt
What the abstract reports
“Studies have demonstrated equal or statistically significant higher gains in maximal strength for daily undulating periodization compared with SPP in subjects with a low to moderate performance level.”
Note: excerpts are short; for full context, read the paper.
Limits
Limitations and bias
- • Abstract-only summaries can miss critical details (population, protocol, adherence, and context).
- • Reviews and consensus statements mix protocols and populations; recommendations may not match your exact constraints.
- • If your context differs (elite vs recreational; cycling vs running), adjust expectations and be conservative.
- • This is performance information, not medical advice.
