Quick answer
Reaction time matters, but the best start is not merely the quickest departure from the pad. It must be legal and connect efficiently into the first contacts and acceleration phase.
Reaction is only one component
Research reviewing Olympic Speed found reaction time relevant to performance, but differences of a few hundredths must be considered alongside first-move quality. An athlete can react quickly and still lose time through poor trajectory or contact.
Use variable start signals
Practice with realistic signals whose timing cannot be predicted. This encourages response rather than countdown guessing. The exact competition start procedure should be learned from current rules and event practice.
Measure beyond pad departure
Film or time the first section. A start change should be judged by when the athlete reaches meaningful route landmarks, not just by the instant the foot leaves the start pad.
Do not train anticipation into a false start
Trying to beat the signal can create a fragile competition habit. SpeedClimbing.com deliberately does not hard-code a permanent false-start threshold; competitors should use current governing rules.
Keep start repetitions purposeful
Starts are neurologically and technically demanding. Stop or change the session when movement quality deteriorates enough that the athlete is rehearsing mistakes rather than the desired pattern.

Research basis
- Performance indicators in speed climbing — review, Olympic video analysis and expert interviews covering power, movement fluency, foot placement, reaction and training.
- Sport climbing performance determinants and functional testing methods — systematic review of testing validity and performance qualities.
- Overuse injury risk factors and prevention in adult climbers — systematic review relevant to load management and strength-and-conditioning context.
The Speed-specific training evidence base is still limited. These pages distinguish direct Speed evidence from broader climbing evidence and avoid presenting speculative methods as established facts.
