Majibu na maelezo huonekana unapojibu maswali.

  1. What does the acute-to-chronic workload ratio summarize?
    • A recent workload relative to a longer-term workload summary
    • A player’s injury severity relative to salary
    • A team’s travel time relative to match time
    • Heart-rate variability relative to sleep duration
  2. Why can injury models be difficult to evaluate when the outcome is uncommon?
    • Every athlete has the same outcome
    • A model can appear accurate while missing many rare injury events
    • Rare events eliminate the need for validation
    • A high accuracy score guarantees useful prediction
  3. Which measurements did the Australian football workload study use?
    • Ticket scans and social-media posts
    • Only heart-rate variability
    • GPS, accelerometer, and player-perceived exertion data
    • Only video of match officials
  4. What does an injury-forecasting model estimate?
    • A guaranteed date of injury
    • A clinical diagnosis without examination
    • A certain training prescription
    • A probability or risk estimate for a defined outcome and period
  5. What did Carey et al. report for non-contact injury prediction on the later season?
    • Performance was only marginally better than chance, with AUC below 0.65
    • Every outcome had perfect accuracy
    • AUC was always 1.0
    • The study did not test a later season
  6. What validation gap did the 2026 systematic review report for all included studies?
    • All used a separate country for testing
    • None used external validation
    • All models were tested prospectively in clinics
    • No study reported any outcome metrics
  7. Which split did the Australian football study use to test its injury forecasts?
    • It mixed all three seasons randomly for every result
    • It trained only on injury labels from the third season
    • It trained using the first two seasons and evaluated predictions on the third
    • It evaluated only on the training rows
  8. What do sensitivity and specificity measure in an injury model?
    • They both measure only training speed
    • Sensitivity is cost and specificity is model size
    • They are alternative names for data leakage
    • Sensitivity concerns detecting injured cases; specificity concerns correctly identifying non-injured cases
