Description

Electric treadmill with motor running controlled by armrest switch

Technical Field

An electric treadmill with a motor controlled by a handrail switch belongs to the field of fitness equipment, and particularly relates to an electric treadmill with a motor controlled by a handrail switch.

Background

When we are walking or running, our arms will swing back and forth naturally, and we do so to maintain balance and prevent falls, however, if we are walking or running with their arms swinging back and forth naturally from the viewpoint of energy consumption by exercise alone, is energy saved or consumed? From the exercise point of view, is the natural swinging back and forth of the arms the best for our human body? This was studied in detail by a team led by the biomechanical specialist Christopher Arellano from the university of brownian: they run 13 jogging people on a treadmill, initially with the subject running in a normal speed, natural, swinging back and forth motion of their arms, with the investigator measuring the frequency of oxygen they need to breathe and carbon dioxide they exhale, and then the subject runs in three different ways: one with both hands on the back, one with both hands on the chest, and the last with both hands on the head. From their article published in journal of Experimental biology, experiments have shown that swinging the arms saves 3% of energy than placing the hands at the back, 9% more than placing the hands at the chest, and 13% more than placing the hands at the head. Scientists explain that while swinging both arms consumes energy, swinging both arms motionless consumes more energy because swinging both arms can reduce the sloshing of the upper body. The upper body accounts for 40% -50% of the total weight, and the double arms only account for 10%. That is, from the viewpoint of exercise effect, the exercise effect is the worst in the normal walking or running with both arms swinging back and forth naturally, compared with the normal walking or running with both hands not moving, but the exercise effect is the best in the normal walking or running with both arms not moving, and the exercise effect is the best in the normal walking or running mode with both hands placed on the head, the second time with both hands placed on the chest, and the certain effect in the back-to-back, that is, the normal walking or running mode with both hands not moving, such as the normal walking or running mode with both hands placed on the head, the chest, and the back, etc., is the exercise mode better than the normal walking or running mode with both hands swinging.

Walking with a stick (i.e. walking with a stick held by two hands, the stick can also be called holding rod, and the stick is used interchangeably hereinafter) is also called cross-country walking, originates from finland, evolves from cross-country skiing sports, and is one of the fastest-developing outdoor aerobic sports internationally. The walking stick is held to walk on the basis of ordinary walking, and the upper limbs are mobilized to participate in the movement through the two walking sticks, so that the whole body exercise is realized. The walking stick is pushed by two hands in front of each other, so that the walking stick can move to the upper half of the body, back and abdomen muscles, legs and arms can be strengthened, the cardio-pulmonary function can be promoted, only two legs are used for normal walking, 70% of muscles of the body participate in movement during ordinary walking, 90% of the body participate in movement during walking with the stick, the energy consumption is 46% higher than that during ordinary walking, the force born by knees and other lower joints is reduced due to the force of the arms, the pressure on waist and legs is reduced, the joints of lower limbs are protected, and the risk of falling is reduced. The multifunctional health-care bed has the characteristics of simplicity, easiness, safety, high exercise effect and the like, has the functions of reducing fat, preventing and treating cardiovascular and cerebrovascular diseases, diabetes and osteoporosis, relaxing mood, reducing pressure and the like, and is an upgraded version of walking.
