Accelerating Post-exercise Muscle Glycogen Resynthesis in Humans: Impact of Combined Nutrient Intake and Intermittent Pneumatic Compression or Heat Therapy

Accelerating Post-exercise Muscle Glycogen Resynthesis in Humans: Impact of Combined Nutrient Intake and Intermittent Pneumatic Compression or Heat Therapy

To determine if modalities designed to improve blood flow combined with post-exercise nutrient intake will improve replenishment of muscle glycogen better than nutrient intake alone. A secondary objective is to compare the effectiveness of heat therapy and intermittent pneumatic compression on glycogen replenishment.

Inclusion Criteria:

1. Subjects will be male and female participants in good health

4. Understanding of the procedures to be undertaken as part of the study
5. Willingness to participate in exercise testing and follow instructions provided by the experimenter
6. Informed, voluntary, written consent to participate in the study

Exclusion Criteria:

1. History of deep vein thrombosis
2. Obesity (BMI > 30 kg/m2)
3. Hypertension (resting SBP > 140/90 mmHg)
4. Smoking
5. Pregnant, planning to become pregnant, or lactating
6. Supplements containing antioxidants including vitamin C and E and N-acetyl cysteine
7. Any medication
8. Lactose intolerance
9. Participation in another study within the previous 30 days or in a PepsiCo funded study within the past 6 months.
