Almond for Physical Performance

Roles of Almonds in Physical Performance

Investigators specific aims are to compare the effects of consuming daily snacks of raw, shelled, unsalted almonds (2.0 ounces) versus an isocaloric amount of another commonly consumed snack food (pretzels) on energy (vigor) perception and physical activity, exercise performance (VO2max and measures of strength), strength and power performance as well as muscle soreness recovery after strenuous eccentrically-biased exercise.

Study Overview

• Status: Completed
• Conditions: Muscle Soreness; Energy
• Intervention / Treatment: Other: Almond; Other: Control group

Detailed Description

To accomplish these aims, investigators will examine whether regular consumption of almonds versus a common snack food over a period of 8 weeks impacts longer term metabolic, physiological and behavioral responses related to energy sensations and exercise capacity/performance.
