Estimation of Energy Expenditure with Two Different Footwear’s in Normal Healthy Females (original) (raw)

Background: Footwear plays an important role while walking. Complaints of foot pain and disability are more common in women. The Physiologic Cost Index (PCI) derived by MacGregor is a tool to calculate the energy expenditure, as an alternative to Laboratory & Caloric Measurements. Objective: To estimate energy expenditure for walking with two different footwears (flat flip flops and sports shoes) in normal healthy females. Method: 100 Female subjects with Normal BMI aged between 20-30Years were assessed to calculate the PCI, First with flat flip-flops and then with an ideal pair of sports shoes (control group), during walking at their chosen speeds over 15 consecutive lengths of a 40m oval track (total walking distance 600m). Resting and Walking heart rate was recorded. Speed was calculated using the standard mathematical equation (Speed = Distance/time). Two PCI values were calculated for each individual, using the McGregor's Equation. Result: The Mean Walking Speed with flip-f...
