  • 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 syndroms occur (shaki, confused, srok), treart impetately with fast- acting glucose (glucose tablets, juice, or gel), then follow with sustained carbohydrate.
