Wearable technology for athletes: Information overload and pseudoscience?
Key Results
Editorial without an abstract; the summary below is from the full text and could not be checked against an abstract (none is indexed)
Two central concerns about wearable technology for athletes:
1. Excessive data generation creating information overload — more metrics does not mean better decisions
2. Promotion of unsubstantiated/pseudoscientific claims by device manufacturers
Marketing claims outpace scientific validation
Athletes and coaches often lack the training to interpret complex physiological data
Mechanism
The authors' argument, not tested: manufacturers are incentivised to add metrics to differentiate products; each added metric increases the user's cognitive load, and unvalidated metrics shown with false precision create an illusion of scientific rigour.
Practical Application
Not all metrics are created equal — an editorial by leading applied sport scientists warning that wearable output outruns validation and overloads users; supports the metric hierarchy in Altini REF-397
Marketing is not science — question every new metric a device claims to provide
More data does not mean better training decisions — often the opposite REF-396
Not from this paper; the base's own practice: if a metric has no peer-reviewed validation, treat it with strong skepticism
Limitations
Editorial, not a systematic review — expert opinion
Published 2016 — the wearable field has evolved

How this entry was checked and changed
Why this level
regraded 2026-09-27 from B: two-page editorial, no data or systematic method
Content correction 2026-09-27
Level B -> C+ (regraded: a two-page editorial is expert opinion, not a review with method).
Tier "mixed (review/meta)" -> N/A (no study population).
"Rule of thumb: didn't exist 10 years ago..." -> labelled as the base's own practice; not from the editorial.
Noted that no abstract is indexed, so the summary is unverified full-text reading.
