The training-injury prevention paradox: should athletes be training smarter and harder?

Gabbett TJ · British Journal of Sports Medicine

Injury risk rises when acute workload spikes well above the chronic workload an athlete is prepared for — an acute:chronic ratio of 1.5 or more carried two to four times the injury risk in cricket bowlers and a weekly increase of 15% or more took injury likelihood to 21–49% in the author's unpublished rugby-league data — while athletes accustomed to high chronic loads have fewer injuries; the proposed sweet spot is a ratio of 0.8–1.3: 'train harder AND smarter'.

Population

Team-sport and endurance athletes across workload-injury studies

Intervention

Rapid spikes in acute workload relative to chronic (rolling 4-week) workload

Comparator

Gradual, consistent load progression

Limitations

Narrative synthesis of observational team-sport data, much of it the author's own rugby-league work, with the injury-prediction model unreplicated; injury endpoints are mostly soft-tissue, not cartilage-specific. No competing interests declared; no funding statement.
