Compared in the reviewR3 · 22 full-text papers, 15 abstract-only

At least one paper behind this review states what this option was measured against. That is not a ranking, and this option carries no evidence profile of its own.

    Bone Health in Endurance Athletes: Runners, Cyclists, and Swimmers

  • High-intensity interval training with 30-second all-out front crawl intervals followed by 3 minutes of passive recovery. Sets increased from 6 to 10 over 16 weeks. Warm-up: 5 minutes of slow dynamic movements for upper and lower limbs. Intensity target: Maximum effort, aiming for "very, very hard" on the Borg scale.

Equipment

Equipment is a property of the movement and is authored, never derived from the evidence corpus (docs/research/round2/ROUND2_KNOWN_CORRECTIONS.md §1). This option is 2 catalogue exercises rather than one, and their equipment differs, so none of them speaks for it.

Level and prerequisites

  • Swimming ability; focuses on aerobic capacity rather than high-intensity tolerance.

Progression and regression

  • Progression from 6 sets of 30-second all-out intervals with 3 minutes recovery to 8 sets, and finally to 10 sets over 16 weeks.

Who should not do this

The papers behind this option report nothing on contraindications, which is not the same as saying there are none.

Setting, as the studies used it

  • Facility or specialist equipment (pool), can be done in a gym or facility

What the papers compared it with

A paper measuring one option against another does not make the two interchangeable, and it does not say which to choose. These are listed as what the papers did, and nothing here proposes a substitution.
