Sleep quality improves across a competitive season in collegiate female rowers
This prospective observational study of 12 collegiate female rowers found that sleep quality significantly improved from early to late season (p = 0.009), with small-to-moderate effect sizes. Fatigue, confusion, and total mood disturbance also decreased significantly, while sleep quantity remained unchanged.

The Claim
Sleep quality improves across a competitive season in collegiate female rowers
This conclusion is most relevant to: Collegiate female rowers (12 athletes).
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸Mood States Across a Competitive Season in Collegiate Female Rowers: A Prospective Observational Analysis. (International journal of exercise science, 2026) —
How It Works
The proposed biological pathway:
- ▸Athletes adapt to training and competitive demands over the season
- ▸Reduced fatigue and confusion accompany improved psychological well-being
- ▸Perceptual and recovery-related factors (e.g., sleep quality) improve with adaptation
- ▸Result: Sleep quality increases and negative mood states decrease by late season
Who Might Benefit
Evidence fit by population:
- ▸Collegiate female rowers (12 athletes)
Recommended Dose
N/A
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Small sample size (n=12) limits generalizability
- ▸Observational design cannot establish causality
- ▸Self-reported sleep quality and quantity may be subject to recall bias
Frequently Asked Questions
Did sleep quantity change across the season?▼
No, sleep quantity remained similar throughout the season; only sleep quality improved significantly.
What mood states improved in the late season?▼
Fatigue, confusion, and total mood disturbance (TMD) were significantly lower in the late season compared with early season.
Was training distance related to mood disturbance?▼
No, weekly training distance was not significantly related to mood disturbance, suggesting psychological responses were more linked to perceptual and recovery factors.
How was sleep quality measured?▼
Sleep quality was assessed via self-report (likely a single-item rating or similar), not polysomnography or actigraphy.
