Almond consumption during a walking intervention in relation to heart rate recovery
Description
ABSTRACT
Objective: The purpose of this randomized parallel two-arm trial was to examine the effect that an intervention of combining daily almond consumption (2.5 ounces) with a walking program would have on heart rate recovery and resting heart rate when compared to the control group that consumed a placebo (cookie butter) in men and postmenopausal women, aged 20-69, in Phoenix, Arizona.
Design: 12 men and women from Phoenix, Arizona completed an 8-week walking study (step goal: 10,000 steps per day). Subjects were healthy yet sedentary, non-smokers, free from gluten or nut allergies, who had controlled blood pressure. At week 5, participants were randomized into one of two groups: ALM (2.5 oz of almonds daily for last 3 weeks of trial) or CON (4 tbsp of cookie butter daily for last 3 weeks of trial). Body weight, BMI, and percent body fat were measured using a stadiometer and Tanita at the screening visit. Resting heart rate, heart rate recovery, and anthropometric measurements were taken at weeks 0, 5, and 8.
Results: 8 weeks of walking 10,000 steps per day, with or without 3 weeks of almond consumption did not significantly improve heart rate recovery (p=0.818) or resting heart rate (0.968).
Conclusions: Almond consumption in combination with a walking intervention does not significantly improve heart rate recovery or resting heart rate.
