Why Protein Matters During Endurance Events

QC sTAMINA JAPAN

QC (Quick Charge) is not your normal protein.
It’s designed specifically for endurance racing—light, fast-absorbing, and easy on the stomach.

Why protein during a race?

  • Prevents muscle breakdown when carbs run low
  • Supports muscle function & recovery even mid-race
  • Helps delay fatigue and maintain mental focus

Why QC stands out?

  • Superior bioavailability & absorption → works when you need it most
  • Portable race-friendly sachets, no heavy shakes
  • Designed for performance, not just recovery

QC = Protein for racing, not just protein.

1. Muscle Repair & Adaptation During Training and Racing
Endurance activities like long-distance running or cycling cause metabolic stress and micro-damage to muscle proteins. Consuming protein helps stimulate muscle protein synthesis and supports recovery and adaptation to training loads.

2. Preventing Muscle Breakdown (Gluconeogenesis)
When carbohydrate stores drop—typically after ~90 minutes of sustained exercise—the body may start using amino acids from muscle tissue for energy (via gluconeogenesis), which weakens muscles and performance. Providing protein during the event helps prevent this “muscle cannibalization.”

3. Supporting Training Adaptation & Endurance Performance
Research suggests that endurance athletes benefit from daily protein intakes of around 1.8 g/kg body weight, with potentially higher needs (~2.0 g/kg) on low-carb or high-intensity training days. Post-exercise protein (approx. 0.5 g/kg) further aids recovery, repair, and adaptation.

4. Modest Performance Gains with Protein Supplementation
A recent meta-analysis found protein supplements may modestly increase lean mass and significantly improve time to exhaustion when compared to carbohydrate-only fueling—allowing athletes to sustain effort longer.


What Makes QC Stamina (Quick Charge) Stand Out

  • Engineered for race-day use, not typical post-workout recovery shakes. It’s designed to be digestible, lightweight, and usable intra-race to maintain muscle function and stamina.
  • Helps sustain muscle output, particularly during long efforts when carbs alone may not suffice.
  • Promotes mental sharpness and reduces central fatigue—critical in later stages of ultra-distance events.
  • Convenient fueling: portable sachets (take one every 2–3 hours) that minimize gut distress and are easy to integrate into race nutrition.

Summary: Why Protein (and QC Stamina) Matters During Races

AspectWhy It’s ImportantHow QC Stamina Helps
Prevent muscle breakdownHelps avoid using muscle protein for energyProvides amino acids intra-race
Support adaptation & recoveryPromotes repair and mitochondrial adaptationDelivers protein during prolonged effort
Maintain performance & mental focusPrevent fatigue and maintain strengthBalanced formula supports body & mind
Gastrointestinal toleranceAvoids race-day stomach issuesDesigned to digest easily and be lightweight

QC Stamina is clearly formulated to fill a unique niche in race fueling—providing bioavailable protein support during long endurance efforts when traditional carbs may fall short. Its emphasis on easy digestion and sustained energy distinguishes it from typical proteins intended for post-exercise recovery.
