VMA-032Z6SprintVO2maxRunning

Tabata Protocol

Supramaximal interval protocol: 7-8 repetitions of 20 seconds at maximal effort (~170% vVO2max) with 10 seconds complete rest. Unique session improving both VO2max and anaerobic capacity simultaneously.

Tips

Effort must be truly maximal on each 20-second repetition
The 10-second rest is complete: full stop, no jogging
A single set is enough, quality over volume
Thorough warm-up is essential given the supramaximal intensity

Common Mistakes

Pacing effort instead of sprinting at 100% on each repetition
Jogging during the 10-second rest instead of stopping
Doing multiple sets without being ready for this intensity

Nutrition & Recovery

Nutrition

Eat your last meal at least 3 hours before the session for optimal digestion.
Carb snack 1 to 1.5 hours before: banana, energy bar, or applesauce.
Avoid high-fiber and high-fat foods before the session (legumes, fried foods).

Hydration

Drink 400 to 500 ml of water in the 2 hours before the session.
Top up with 200 ml in the 15 to 30 minutes before heading out.
Avoid diuretic beverages (excessive coffee, alcohol) in the hours before.

Why it works

Why this format

VO2max represents the ceiling of aerobic capacity. Specific training aims to maximize cumulative time spent between 90-100% of VO2max per session. Adaptations are both central (cardiac output) and peripheral (muscle oxygen extraction). Short-short intermittent (30/30) or long interval (3-5 min) formats allow accumulating 10-15 effective minutes at VO2max per session.

Zones solicited

Recovery

Active recovery in Z1 maintains high blood flow, accelerating metabolic clearance between intense repetitions.

Expected adaptations

VO2max increase of 5-15% depending on baseline fitness (greater gains in less trained individuals)
Eccentric cardiac hypertrophy: increased left ventricular end-diastolic volume
Improved capillary density and peripheral oxygen extraction (a-vO2 diff)
Increased mitochondrial electron transport chain enzyme activity
Improved skeletal muscle buffering capacity
