Elite academy soccer players exhibit compromised sleep quality through fragmentation despite adequate sleep duration
This study of 13 elite U15 academy soccer players found that while total sleep time (431-541 min) and sleep efficiency (84.4%) met age-specific recommendations, wake after sleep onset (53.3 min) and number of awakenings (39.8) substantially exceeded thresholds for good sleep quality. Training days yielded significantly lower total sleep time (431 min) and time in bed (478 min) compared to non-training days (541 min and 596 min, respectively).

The Claim
Elite academy soccer players exhibit compromised sleep quality through fragmentation despite adequate sleep duration
This conclusion is most relevant to: Elite academy soccer players (U15 national league squad, n=13).
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸Objective sleep characteristics of elite academy soccer players: a seven-day actigraphy analysis of a U15 national league squad. (Biology of sport, 2026) —
How It Works
The proposed biological pathway:
- ▸Training and competition schedules impose constraints on sleep opportunity
- ▸Training days reduce time in bed and total sleep time compared to non-training days
- ▸Despite adequate duration, sleep is fragmented with high number of awakenings and wake after sleep onset
- ▸Result: Compromised sleep quality through fragmentation in elite adolescent athletes
Who Might Benefit
Evidence fit by population:
- ▸Elite academy soccer players (U15 national league squad, n=13)
Recommended Dose
N/A
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Small sample size (n=13) limits generalizability
- ▸Actigraphy may overestimate sleep fragmentation compared to polysomnography
Frequently Asked Questions
What sleep parameters were measured in this study?▼
Total sleep time, time in bed, sleep onset latency, number of awakenings, wake after sleep onset, and sleep efficiency were measured using 7-day actigraphy.
Did training days affect sleep differently than non-training days?▼
Yes, training days resulted in significantly lower total sleep time (431 min) and time in bed (478 min) compared to non-training days (541 min and 596 min, respectively).
Did the athletes meet sleep recommendations?▼
Total sleep time and sleep efficiency met age-specific recommendations, but number of awakenings and wake after sleep onset substantially exceeded thresholds for good sleep quality.
What is the main implication of this study?▼
Comprehensive sleep monitoring in elite adolescent athletes should extend beyond duration alone, as sleep fragmentation indicates compromised quality despite adequate duration.
