The way you walk can make a huge difference to the effectiveness of the exercise and the calories you burn, a study suggests.
The study led by Kim Eun-kyung at Gangneung-Wonju National University asked 35 high school students to practice different walking styles.
The youngsters walked at speeds of 2.4 km/h, 3.2 km/h, 4 km/h, 4.8 km/h and 5.6 km/h as if they were walking on a treadmill, strolling with their friends, crossing a street or trying to get rapidly from A to B.
Their activities were monitored to analyze energy consumption and intensity of exercise with respiratory gas analyzers.
Walking fast consumed the most energy at 5.8 to 9.1 kcal/kg, more effective than walking at a speed of 5.6 km/h on a treadmill. Strolling was the least energy-consuming type of walking at 2.8 to 4.4 kcal/kg.
Walking briskly as if crossing a street resulted in an energy consumption level of 3.6 to 5.7 kcal/kg.
The study was published in the latest edition of the Journal of the Korean Dietetic Association.
