Abstract

Objective: The purpose of this study was to evaluate the relationship between anthropometric measures with heart rates (HR) at specific blood lactate concentrations [bLa] during exercise.

Method: Participants and data for this study were collected by an orthopedic rehabilitation center in Central Illinois. Participants underwent lactate testing following METHOD CRA protocol on an upright cycle and an optional DEXA scan. Heart rate values at Prime (2 mmol/L), Anaerobic (4 mmol/L) and Peak (6 mmol//L) blood lactate concentrations were recorded. Data was analyzed using Pearson correlations.

Results: A total of 59 participants were included. Participants ages ranged from 21 – 74 years old and had on average a BMI of 34.3 kg/m2 (SD = 8.34), WC of 104.9 centimeters (SD = 22.1), and WHtR of 0.61 (SD = .012). The study found a statistically significant negative correlation between PRHR and WC (p = .020) as well as PRHR and WHtR (p = .030).

Conclusion: There was a stronger negative relationship between WC and WHtR with PRHR than there was with BMI Other variables approaching significance in this sample include a negative relationship between both WC and WHtR with ANHR. This indicates that central adiposity may have a stronger connection with HR values at a specific lactate level during aerobic and anaerobic exercise that cannot be indicated with BMI alone.
