Functional Vs. Running Low-Volume High-Intensity Interval Training: Effects on VO(2)max and Muscular Endurance.
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: randomized trial.
- • 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
The purpose of the study was to assess if high-intensity interval training (HIIT) using functional exercises is as effective as traditional running HIIT in improving maximum oxygen uptake (VO(2)max)… (randomized trial; n=11 trained participants).
The abstract doesn’t indicate a clear change in VO₂max 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 the study was to assess if high-intensity interval training (HIIT) using functional exercises is as effective as traditional running HIIT in improving maximum oxygen uptake (VO(2)max)…
- • The abstract doesn’t indicate a clear change in VO₂max under the tested conditions.
- • Population: n=11 trained participants.
- • Protocol cues (title/abstract): 5 min.
Protocol
Protocol (as reported)
- • Intervention/exposure: endurance, interval (vs comparison group).
- • Dose/time/duration cues in abstract/title: 5 min.
- • 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 (n=11 trained 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: randomized trial.
- • Population: n=11 trained participants.
- • Comparator: comparison group.
- • Outcomes measured: VO₂max, Lactate threshold.
- • Protocol cues mentioned: 5 min.
- • Source: PubMed PMID 31427872 (2019) — Journal of sports science & medicine.
Results excerpt
What the abstract reports
“Mean and peak HR during the training sessions were significantly different (p = 0.018 and p = 0.022, respectively) between training groups, with HIIT-F eliciting lower HR responses than the HIIT-R.”
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).
- • 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.
