Calisthenics-based Tabata HIIT improved endurance, strength and power as much as running-based Tabata in 334 cadets
An equipment-free stimulus, not a superior one
Participants
n=334 male gendarmerie cadets, randomly assigned to Tabata running (n=154) or Tabata calisthenics (n=180).
Protocol
Both protocols 3 times a week for 5 weeks: 20 s high-intensity exercise / 10 s rest, repeated for 2–4 sets.
Tests before and after: 30-m sprint, 2,400-m run, standing long jump, crunch, push-up, overhead medicine-ball throw, pull-up, isometric leg strength and isometric back strength.
Key Findings
Both groups improved significantly on all tests (p = 0.000).
No significant time × group interaction on any test (p = 0.098–0.892) except the crunch test (p = 0.018) — the abstract does not state which group gained more on the crunch.
The authors' reading: similar physical improvements in both groups, with significant progress in aerobic endurance, muscle strength and muscle endurance; calisthenics HIIT may suit military/law-enforcement settings because it needs no equipment or space.
Practical Application
In 334 cadets over 5 weeks, 3 sessions/week of Tabata (20 s / 10 s, 2–4 sets) improved endurance, strength and power whether the 20-s bouts were running or bodyweight exercises, with no between-group difference on any test but the crunch. When equipment and time are limited, bodyweight Tabata circuits deliver the same combined stimulus as running Tabata — an equivalence result, not a win for calisthenics.
Not from this paper; the base's own practice: keep true endurance-specific work if a race demands it — circuits complement, not replace, sport-specific volume.
Limitations
Single trial in male cadets; no non-training control group, so the improvements are "both protocols", not "vs doing nothing". "Comparable endurance" is context-specific and may not transfer to trained endurance athletes.
5 weeks only; the one between-group difference (crunch test) is not characterised in the abstract.

Why this level
regraded 2026-09-27 from B: randomised parallel trial with 334 participants (well-powered), single study, no control group
Content correction 2026-09-27
"superior strength and power gains" for calisthenics -> the abstract reports no significant time × group interaction on any test except the crunch test; both groups improved similarly. Title, findings and lead rewritten as equivalence.
Added n=334 (154 running + 180 calisthenics), the protocol (3×/week, 5 weeks, 20 s / 10 s, 2–4 sets) and the test battery from the abstract.
Level B -> A- (randomised parallel trial, n=334); Tier "2-3 (cadets, active)" -> Tier 1-2.
