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: systematic review / meta-analysis.
- • Population relevance: mixed/unclear athlete specificity.
- • Consistency: synthesis evidence present.
- • Practical recommendation depends on tolerance, context, and whether it protects training consistency.

To analyse the effects of HIIT and ET on the VO(2peak) of seniors aged 65 years or older when compared with controls and also when the two types of… (systematic review / meta-analysis; participants).
In this systematic review / meta-analysis, the abstract suggests a positive relationship with VO₂max. Treat this as a signal, not a guarantee; confirm methods and context in the full paper.
Takeaways
What the abstract suggests
- • Study question: To analyse the effects of HIIT and ET on the VO(2peak) of seniors aged 65 years or older when compared with controls and also when the two types of…
- • In this systematic review / meta-analysis, the abstract suggests a positive relationship with VO₂max.
- • Population: participants.
- • Protocol cues: abstract may omit dose/timing; use the full paper to replicate accurately.
Protocol
Protocol (as reported)
- • Intervention/exposure: endurance, interval.
- • Dose/time/duration: abstract doesn’t include enough detail; use the full paper’s methods section.
- • Outcomes: VO₂max, Lactate threshold.
- • 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 (participants) working on endurance.
- • Athletes who can measure VO₂max, Lactate threshold 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: systematic review / meta-analysis.
- • Population: participants.
- • Outcomes measured: VO₂max, Lactate threshold.

Results excerpt
What the abstract reports
“Furthermore, VO(2peak) was found significantly higher not only when compared HIIT with controls (MD = 4.61; 95% CI: 3.21-6.01), but also when compared HIIT with ET (MD = 3.76; 95% CI: 2.96-4.56).”
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.
