Late-Session Drop
+6ms
2% decline
Peak capacity is strong, but not consistently accessed. Right-side reactions lag left by 11ms, and timing precision softens under late-session load.
WHY the gap exists
Right-side reactions run 11ms slower than left, and left-side timing degrades 19ms from early to late session—these asymmetries limit bilateral balance and sustained precision.
WHAT is limiting performance
Uneven trigger speed between sides and gradual left-side slowing under load; the athlete isn't maintaining demonstrated 213ms best-case capacity consistently.
HOW it can be unlocked
Lateralized reaction training to equalize side-to-side speed; end-of-session neuromotor blocks to prevent left-side degradation; perception drills for decision accuracy under interference.
REACTION & ANTICIPATION
Dive Reaction Speed & Consistency
How fast and reliable are left vs right dive reactions?
Avg reaction | Dashed line = worst observed
Right-side reactions are 11ms slower on average; occasional extreme outliers show consistency challenges exist on both sides.
Coach: "Watch film: On right-post dives from central position, does initial movement look subtly delayed compared to left-post dives? The 11ms shows mechanically."
Best-Case Reaction Capacity
What is the athlete's response system capable of when the read is clear?
Best trials show 213ms (left) and 230ms (right) capability exists, but average performance sits 28ms slower.
Coach: "Watch training: What separates his fastest reactions from average ones? Read clarity? Confidence? Identifying the state difference unlocks more consistent speed access."
Reaction Consistency
How repeatable is reaction speed across trials?
Reaction times range from 213ms to 303ms with typical performance at 246ms—9.1% variability indicates moderate consistency with occasional slow outliers.
Coach: "Watch session patterns: Do the slowest trials cluster late in training, or scatter randomly? That distinction reveals whether it's fatigue or attention drift."
DECISION TIMING & CONTROL
Commit Speed Under Conflict
How quickly can the athlete commit when the first read is wrong?
Penalty for overriding initial read is only 19ms—low conflict cost shows good adaptive ability.
Coach: "Watch one-v-one scenarios: On late shot fakes or deflections, does he switch commitment cleanly, or hesitate mid-action? The 19ms is visible as decisiveness."
Decision Accuracy Under Complexity
How reliable are commits when the situation is complex?
Accuracy drops 6 points under interference—speed preserved but correctness decreases.
Coach: "When the read is wrong, does speed override accuracy or vice versa?"
Brain-to-Body Alignment
Do brain planning and body execution stay synchronized across the session?
Brain and body start together at 77% early session and improve in lockstep to 93% late—perfect convergence means no brain-body disconnect under load.
Coach: "This athlete's brain and body adapt together as session progresses. No mismatch between planning and execution—both systems strengthen late."
STABILITY & SESSION DURABILITY
Late-Session Timing Stability
Does timing quality hold when fatigue increases?
Variability is moderate; workload trend increases from mid to late session.
Coach: "In the last 10 minutes of training or late-match saves, does timing look different from early work?"
Left-Right Symmetry Under Load
Are both sides balanced early and late session?
Early Session (23ms gap)
Late Session (7ms gap)
Scale: 0–300ms | Taller bars = slower reactions
Early session shows 23ms asymmetry (right slower); late session shows 7ms asymmetry. Left degrades 19ms while right stays stable.
Coach: "Watch dive speed late in training: If left-side saves look subtly slower by minute 80 compared to early work, that's the 19ms degradation showing physically."
Session Drop-Off
How much does performance fall across the session?
Neural control declines 6ms (2%) from start to end of session—moderate degradation shows timing precision softens under accumulated cognitive and physical load.
Coach: "Watch final training reps: If late-session saves lack the snap of early work, that's the 2% neural drop showing as reduced explosiveness."
Secondary Detail
Neural Drift (Session)
Decision sharpness across session
Workload rises through session while attention stabilizes after early variability.
Coach: Monitor late-training quality; if timing degrades in final 15 minutes, consider shorter high-intensity blocks.
Brain-Body Convergence
Is timing issue brain or body-driven?
Brain and body align perfectly (100% convergence)—no mismatch between neural planning and physical execution.
Coach: Focus on external factors (decision accuracy, bilateral balance) rather than internal neural-motor disconnect.
Emerging Risk Flags
Performance Degradation Signals
Mechanical / Injury-Relevant Signals
Left-side timing degrades +19ms late session while right-side 11ms baseline lag persists—bilateral asymmetry combines with fatigue.
Coach: Track L/R reaction times in every lateral session; implement end-of-session neuromotor quality blocks.
