Abstract Introduction:<\b>
Phase angle is derived from bioelectrical impedance and is becoming widely accepted as an indicator of cellular health. Indeed, research suggests phase angle may be a simple measure associated with a range of health and fitness variables. Considering the simplicity of this non-invasive measure, this study examined relationships between phase angle, and a range of health and fitness measures in participants recommended for exercise referral by their General Practitioner.Method: One hundred and forty-six participants (females = 92, males = 54; age 49±14 years) were recruited across 3 sites participating in an exercise referral scheme. Upon entry to the scheme participants body mass, body mass index (BMI), body composition, resting blood pressure, resting heart rate, predicted aerobic capacity, and muscular strength were measured. Phase angle was also measured using bioelectrical impedance. Relationships between these variables and phase angle were examined using Pearson’s or Spearman’s correlations dependent upon distribution. Results are presented as correlation coefficients and 95% confidence intervals. Results:<\b>
Phase angle was found to be significantly correlated with age (r = -0.392; -0.240 to -0.525), body mass (r = 0.205; 0.038 to 0.361), lean mass (r = 0.353; 0.197 to 0.492), and muscular strength (r = 0.368; 0.186 to 0.525). Conclusion:<\b>
Phase angle was associated with age as well as other indicators of health and fitness. These were primarily related to muscular health (i.e. lean mass and muscular strength). Considering its ease of administration, phase angle might be considered as a simple indicator of cellular and overall muscular health.
