Healthy

Outcome Measures

Primary Outcomes (4)

• Glucose Homeostasis: Glucose

  Changes in serum blood glucose (mmol/L) obtained from venous blood draws and analyzed General Linear Model multivariate and univariate analyses with repeated measures and mean change from baseline with 95% confidence intervals (CI's).

  Measured prior to supplementation (Pre), 30-min after ingestion of supplement and after performing the 80-min exercise bout (Post-Exercise), and after 48 hours of recovery from exercise bout (Recovery) during each treatment.

• Glucose Homeostasis: Insulin

  Changes in serum insulin (µIU/mL) obtained from venous blood draws and analyzed General Linear Model multivariate and univariate analyses with repeated measures and mean change from baseline with 95% confidence intervals (CI's).

  Measured prior to supplementation (Pre), 30-min after ingestion of supplement and after performing the 80-min exercise bout (Post-Exercise), and after 48 hours of recovery from exercise bout (Recovery) during each treatment.

• Glucose Homeostasis: Insulin to Glucose Ratio

  Changes the insulin to glucose ratio obtained from venous blood draws and analyzed General Linear Model multivariate and univariate analyses with repeated measures and mean change from baseline with 95% confidence intervals (CI's).

  Measured prior to supplementation (Pre), 30-min after ingestion of supplement and after performing the 80-min exercise bout (Post-Exercise), and after 48 hours of recovery from exercise bout (Recovery) during each treatment.

• Exercise Glucose Response

  Changes in arterialized-venous blood glucose (mmol/L) obtained from a dry finger and analyzed by General Linear Model multivariate and univariate analyses with repeated measures and mean change from baseline with 95% confidence intervals (CI's).

  Measured at baseline (0-min); 30-min post ingestion of supplement, midway (60-min) and following (90-min) resistance exercise, following sprint condition exercises (110-min), and following post-exercise assessments (130-min) during each treatment.

Secondary Outcomes (32)

• Subjective rating of hypoglycemia

  Measured prior to supplementation (Pre), 30-min after ingestion of supplement and after performing the 80-min exercise bout (Post-Exercise), and after 48 hours of recovery from exercise bout (Recovery) during each treatment.

• Subjective rating of dizziness

  Measured prior to supplementation (Pre), 30-min after ingestion of supplement and after performing the 80-min exercise bout (Post-Exercise), and after 48 hours of recovery from exercise bout (Recovery) during each treatment.

• Subjective rating of headaches

  Measured prior to supplementation (Pre), 30-min after ingestion of supplement and after performing the 80-min exercise bout (Post-Exercise), and after 48 hours of recovery from exercise bout (Recovery) during each treatment.

• Subjective rating of fatigue

  Measured prior to supplementation (Pre), 30-min after ingestion of supplement and after performing the 80-min exercise bout (Post-Exercise), and after 48 hours of recovery from exercise bout (Recovery) during each treatment.

• Subjective rating of stomach upset

  Measured prior to supplementation (Pre), 30-min after ingestion of supplement and after performing the 80-min exercise bout (Post-Exercise), and after 48 hours of recovery from exercise bout (Recovery) during each treatment.
