What do HYROX athletes do to train and recover?

An ad hoc survey of 80: mostly men with a functional or endurance background, recovery often unstructured in the authors' view. What people report, not what works.

Main caveat: Abstract only. The host refused the request; instrument, items, numbers, recruitment and funding were not read.
limited, mixed evidenceMeasured on recreational to highly trained athletes

Villarroel López and colleagues used an ad hoc questionnaire to describe 80 active HYROX athletes: training frequency and structure, previous athletic experience, strength and endurance levels, recovery practices and personal goals.

The abstract reports a mostly male profile with high physical demands and prior experience in functional or endurance sports, generally well-developed strength and endurance by the athletes' accounts, and recovery strategies that were often unstructured or insufficient, which the authors suggest may harm performance and raise injury risk.

They conclude that structured recovery should be added. Our reading: a small descriptive picture. The recovery conclusion goes beyond the design, since nothing compared those with structured and unstructured recovery; the abstract states no number for any of its findings.

Protocol

Design: descriptive analysis of an ad hoc questionnaire.
Sample: n = 80 active HYROX athletes. Recruitment, sex split in numbers, age, division, level and response rate are not in the abstract.
Topics: training frequency and structure, previous athletic experience, strength and endurance levels, recovery practices, personal goals, motivation.
Validation of the questionnaire: not reported in the abstract; "ad hoc" is the authors' word.
Funding and interests: not available from the abstract. Open access, CC BY 4.0, but the publisher's host refused the request. One author, Agudo-Ortega, also co-authors REF-1496.

Key Results

TopicWhat the abstract reports (no numbers given)
ProfilePredominantly male; high physical demands; prior experience in functional or endurance-based sports
CapacitiesGenerally well-developed strength and endurance, as reported
RecoveryOften unstructured or insufficient, in the authors' judgement

No percentages, weekly hours or session counts are in the abstract, so none is quoted here.

Mechanisms

Measured: questionnaire answers at one time point.
Authors' interpretation: unstructured recovery may compromise performance and raise injury risk; they call for comprehensive recovery strategies. Neither link was measured.

Practical Application

What do HYROX athletes do to train and recover? An ad hoc survey of 80: mostly men with a functional or endurance background, recovery often unstructured in the authors' view. What people report, not what works.
Do not use this to prescribe recovery. The claim that recovery is insufficient is the authors' judgement against no outcome. Not from this paper; the base's own practice on recovery and load is in SYNTH-71 and SYNTH-70.
For how much people train: REF-904 logged weekly exposure in a prospective cohort; this entry adds no number.

Limitations

Abstract only. The host refused the request; instrument, items, numbers, recruitment and funding were not read.
Ad hoc, self-reported. An ad hoc questionnaire, validation not reported in the abstract; capacities are as reported.
Small, cross-sectional, likely self-selected. Eighty respondents of unknown level and division; no response rate in the abstract.
No outcome. Nothing links any habit to performance or injury, so the recovery conclusion is an opinion, not a finding.
How this entry was checked and changed
Why this level

a small descriptive survey is B by design; held at B- because the questionnaire is ad hoc and its validation is not reported in the abstract, nothing was read beyond the abstract, and self-reported habits are no outcome (the publisher's host refused the request)
