Practical Protocols for Konkurencja Day Glucose Management

Pre- Konkurencja Phase (24 t 12 Hours Before)

  • Prioritize quality sleep andd minimize non-essential stressors.
  • Consume balanced meals with moderate to high complex carbohydrates, acprovate protein, andlow sativated fat.
  • Hydrate with water andd electrolite- containg fluids; avoid eitil and excessive caffeine.
  • Prowadź trial run of thee dietion and stress management plan during a practice session at similar intensity.

Prevente Pre- Competion Phase (2 to 1 Hour Before)

  • If using a CGM, check baseline glucose and trend direction.
  • For athletes with diabetes, adjuss insulin if needed based on current glucose and expected activity intensity.
  • Praktyka 5- 10 minut przerwy wdech wdech or visualization to lower precidatory stres.

  • Monitoror glucose at natural breaks (halftime, between period, timeouts) if possible.
  • Usie liquid or gel carbohydrates for rapid absorption; avoid high- fat or high- fiber fooding exertion.
  • If hypoglycemic supretoms occur (shaki, confused, srok), treart impetately with fast- acting glucose (glucose tablets, juice, or gel), then follow with sustained carbohydrate.
