Physiological, Psychological and Performance-Related Changes Following Physique Competition: A Case-Series.
Worth trying if it fits your goal and context.
ELI5
In plain language
The purpose of this case-series was to evaluate the physiological, psychological and performance-related changes that occur during the postcompetition period. (controlled study; athletes).
The abstract suggests a positive effect on Sleep quality, Recovery speed under the tested conditions. Treat this as a signal, not a guarantee; confirm methods and context in the full paper.
Takeaways
What the abstract suggests
- • Study question: The purpose of this case-series was to evaluate the physiological, psychological and performance-related changes that occur during the postcompetition period.
- • The abstract suggests a positive effect on Sleep quality, Recovery speed under the tested conditions.
- • Population: athletes.
- • Protocol cues (title/abstract): 2 weeks • 4 weeks • 10 weeks.
Protocol
Protocol (as reported)
- • Intervention/exposure: physiological, psychological.
- • Dose/time/duration cues in abstract/title: 2 weeks • 4 weeks • 10 weeks.
- • Outcomes: Sleep quality, Recovery speed.
- • Replication note: abstracts often omit adherence and timing; confirm details before changing training or supplementation.
Fit
Who it helps, and who should skip it
Who it helps
- • Athletes similar to the study population (athletes) working on sleep.
- • Athletes who can measure Sleep quality, Recovery speed with a repeatable workout or time-trial effort.
Who should skip
- • 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: controlled study.
- • Population: athletes.
- • Outcomes measured: Sleep quality, Recovery speed.
- • Protocol cues mentioned: 2 weeks • 4 weeks • 10 weeks.
- • Source: PubMed PMID 33467243 (2020) — Journal of functional morphology and kinesiology.
Results excerpt
What the abstract reports
“Participants tracked daily macronutrient intake daily for the duration of the study.”
Note: excerpts are short; for full context, read the paper.
Limits
Limitations & bias
- • Abstract-only summaries can miss critical details (population, protocol, adherence, and context).
- • Single studies often don’t generalize to your event, history, and training load; treat results as a starting point.
- • If your context differs (elite vs recreational; cycling vs running), adjust expectations and be conservative.
- • This is performance information, not medical advice.
