Sample the same small panel during an already scheduled bullpen every 7–10 days. The sport scientist reviews disaggregated trajectories rather than a composite score. A provisional warning requires either one measure to remain outside its athlete-specific acceptable band for two comparable sessions or two independent measures to worsen together; an unacceptable state includes a persistent accelerating trend, reported pain, or a clinician-defined concern. Warning triggers a coach-led video, recovery, and context review before the next high-intensity session. Persistence permits the coach to reduce or modify planned throwing and triggers clinical review when symptoms or health concerns are present. Measurements continue after the response to check recovery and recalibrate rules.","mechanism_mapping":[{"counterfactual_removal":"Without a reference condition and bands, ordinary session variability cannot be separated consistently from athlete-specific deterioration.","mechanism_slug":"baseline_condition_model","role":"Defines healthy, acceptable, warning, and unacceptable states from comparable sessions for each pitcher."},{"counterfactual_removal":"Without a compact indicator panel, deterioration remains anecdotal or measurement expands into a burdensome collection exercise.","mechanism_slug":"deterioration_indicator","role":"Combines mechanics, task outcome, exertion, and self-reported arm status so no single convenient metric represents the whole condition."},{"counterfactual_removal":"Without recurring comparable samples, the system cannot identify a slope before a conspicuous failure or complaint.","mechanism_slug":"preventive_inspection","role":"Embeds a low-burden condition check in scheduled bullpen work rather than adding maximal-effort testing."},{"counterfactual_removal":"Without preserved trajectories and persistence rules, isolated noisy observations can cause overreaction while slow drift remains normalized.","mechanism_slug":"trend_monitoring","role":"Interprets direction, rate, persistence, and acceleration within each athlete."},{"counterfactual_removal":"Without explicit warning and unacceptable bands, reports do not specify when review or escalation is required.","mechanism_slug":"repair_threshold","role":"Converts sustained or corroborated degradation into staged action triggers."},{"counterfactual_removal":"Without a named owner and transfer rule, concerning trends can circulate without changing a decision.","mechanism_slug":"accountable_condition_owner","role":"Makes the sport scientist responsible for trend review, the coach responsible for training responses, and the clinician responsible for medical judgments."},{"counterfactual_removal":"Without a response pathway, the proposal becomes passive documentation rather than deterioration management.","mechanism_slug":"response_pathway","role":"Links warning evidence to contextual review, reversible workload or technique changes, symptom-sensitive clinical review, and follow-up measurement."},{"counterfactual_removal":"Without reviewing alarms against later observations and expert judgment, thresholds can remain noisy, stale, or gameable.","mechanism_slug":"false_alarm_review","role":"Records unsupported alerts, missed deterioration, and contextual confounders for periodic recalibration."}],"nearest_rivals":["Training-load caps or acute-to-chronic workload rules limit an input exposure;
