Preparing to perform

February 4, 2026

Race-day warm-ups are a universal feature of competitive swimming, yet they are often based on tradition, habit, or personal preference rather than clear physiological principles.

While many warm-ups “feel right”, fewer are intentionally structured to prepare the swimmer for the specific demands of their event, the competition environment, and the realities of modern meet logistics — across all levels of the sport.

This article introduces a physiology-led, coach-friendly framework for designing competitive race warm-ups. Its a flexible model that can be adapted for age-group, pathway, and senior swimmers.

A three phase warm-up framework

This warm-up is made from three functional phases, each with a distinct purpose. Not all phases will be required or you may want more phases as for every swimmer or event it can be different, but together they provide a complete structure.

Phase 1
Muscle & Stroke Activation

purpose: Elevate muscle and core temperature, improve blood flow, mobility, and stroke mechanics.
Volume: 300–500 m
Intensity: Easy aerobic (<65–70% max effort)
Content: Mixed Swim, Technique-focused drills or a Light kick or pull

Phase 2
Race-Specific Priming

Purpose: Prepare cardiovascular, metabolic, and neuromuscular systems for race demands, reduce early oxygen deficit and rehearse race mechanics and stroke rate
Volume: 150–400 m total, in short reps
Target ~2–6 minutes above the second threshold/race pace in short bursts
Intensity: Race pace to slightly supra-race pace (brief, controlled efforts)
Content: Broken race-pace reps (25–50 m) , turns, stroke rate, breakouts, breathing pattern and Optional brief supra-race bursts for nervous system priming

Phase 3
Neuromuscular Potentiation (Optional, Sprint-Focused)

Purpose: Enhance neural drive and explosive power for starts and early strokes
Volume: 25–100 m (2–4 × 15–25 m sprints)
Intensity: Maximal intent, full recovery between efforts (≥60–90 s)
Content: Short sprints with full starts or push-offs

Six Coaching tips to look out for

Swimmer Readiness & Fatigue

Monitor both physical and mental readiness. Adjust warm-up volume and intensity based on recent training load, sleep, recovery, and swimmer feedback (RPE, stroke quality).
Hydration & Nutrition
Ensure swimmers are hydrated and have consumed the appropriate pre-race nutrition

Psychological Factors

Anxiety, arousal, and focus affect performance; warm-ups should incorporate familiar routines to boost confidence.

Warm-Up Order for Multi-Event Swimmers

If a swimmer has multiple events in a session or day, plan warm-ups strategically to maintain performance for each race.
Consider shorter “mini warm-ups” or Phase 5 maintenance between swims.

Stroke & Event Specificity

Warm-up should reflect the primary stroke and distance of the upcoming race.
Medley or multi-stroke swimmers may require blended warm-up sets to efficiently cover all strokes.

Environmental Factors

Pool temperature: Cooler water may require slightly longer activation.
Air temperature: Consider clothing and Phase 5 strategies to maintain muscle temperature.
Lane availability and pool logistics: Adjust sets to avoid congestion or unnecessary delays.
