Bag Carrying Method during Level Walking Affects Perceived Exertion Ratings without Altering Energy Cost, Oxygen Consumption, and Heart Rate in Healthy Adults: A Randomized Crossover Trial

P often walk with bags of various sizes, since the carrying of luggage for work, travel, and shopping is common. Bags come in various styles, and one-handed, two-handed, one-shoulder, or two-shoulder (a backpack) carrying methods are used based on individual preference and situation (e.g., commuting), weight, and shape of luggage. Although walking with a bag is useful for carrying luggage, it sometimes has an adverse effect on the body and may increase risk of lower back pain and strain on fingers, wrists, and shoulders [1,2]. Additionally, differences in bag carrying methods may influence walking performance (e.g., gait posture, walking cadence, and muscle activity) [1-3].
