Why Blood Glucose Drops During Competition

Hypoglycemia during equisi felis felis when then thee rate of glukose uptake by working muscles exceeds the body 's ability to o supplyy glukose from glykogen stores, hepatic gluconoogenesis, or exogenous karbohydnate intake.

Sport- Specific Prevention Strategies

Thee energiy demands, duration, intensity patterns, and logistical consistents vary widely, and prevention strategies mutt bee tailored consistengly. below are detailed protocols for three major consistent, and glucose actics, with specic applications for carbohydratate timing, insulin considement, and glucose monitoring.

Endurance Events (např., long-distance running, cycling, triatlon, rowing)

In evens lasting over 60 minutes, continuus carbohydrate fueling is non-ecuable. Many elite athles with beth diabetes use a hybrid stray that combine basal insulin reduction with precise carbohydrate intate. Before even, reduce basal insulid by 30 to 50 percent, consiing on th e predicted duration and intensity.

During competion, consume 30 to 60 grams of carcarhydrates per hour from multiplee transportable sugars, such as glukose-fruktose blends. Research shows that combining glucose and fruktose allows for hiwer total carbohydrate absorption rates (up to 90 grams per hour) because they use different conteninaol transporters.

For team sports with multiplee games in a single day, such as tournaments, recovery between ein matches is kritial. Within 30 minutes of each game, consume 20 to 30 grams of protein and 40 to 60 grams of complex carbohydrates to replenish glykogen and stabilize glucose. Use CGM trend data to guide insulin correcortions for the next match, adzing that postgame age sulin sensitivitivity is typically elevetud.

Power and Combat Sports (např., bithtlifting, powerlifting, boxing, mixed martial arts, wrestling)

In sports with heath-ins or heatt classes, attentes of ten restrict carhydrates and fluids before competion, inadcently increaming hypglycemia risk. Weight cutting, which complives dehydration and calorie restrictioon, depletes glykogen stores and diethers the body 's ability to regulate glukose.

Leveraging Technology: CGM Alarms and Smart Insulin Pens

Modern continuus glucose monitors, such as Dexcom G7, Abbott Libre 3, or Medtronic Guardian 4, allow attens to so set low -glucose alerts that vibrate or send a signal to a smartwatch. During a competition, set the alarm atcold 10 to 20 mg / dl higer than youser usual resting t to buy reaction time.
