  • Aerobic exercise is a popular form of exercise that improves one's cardiovascular health by reducing blood pressure and providing other benefits to the human body. Aerobic exercise generally involves low intensity physical exertion over a long duration of time. Typically, the human body can adequately supply enough oxygen to meet the body's demands at the intensity levels involved with aerobic exercise.
  • Popular forms of aerobic exercise include running, jogging, swimming, and cycling among other types of aerobic exercise.
  • anaerobic exercise typically involves high intensity exercises over a short duration of time.

For example, users of different heights and/or stride lengths may use the same exercise machine and conveniently adjust the stride. Further, users may conveniently adjust the stride to target different muscle groups.

  • a stride adjustment link may connect the arm support to the foot pedal independent of other mechanical linkages.
  • the stride adjustment link may restrict the movement of such mechanical linkages such that the stride length is set at a certain distance.
  • the input mechanism is a rotary dial where turning the rotary dial in a first direction causes the stride length to increase while turning the rotary dial in a second direction causes the stride length to decrease.

Abstract

La présente invention concerne une machine d'exercice comprenant un cadre, une première pédale à pied et une seconde pédale à pied attachées de manière mobile au cadre et placées de manière à se déplacer le long de trajectoires dans un mouvement de va-et-vient. Un mécanisme de résistance de pédale intégré dans la machine d'exercice est en communication résistive avec la première pédale à pied et la seconde pédale à pied, et un premier support de bras et un second bras support sont fixés de manière pivotante sur le cadre. Le premier support de bras est relié mécaniquement à la première pédale à pied, et le second support de bras est relié mécaniquement à la seconde pédale à pied, et une première liaison de réglage du pas est reliée de manière coulissante au premier support de bras au niveau d'un premier ensemble de connexion, et une seconde liaison de réglage du pas est reliée de manière coulissante au second support de bras au niveau d'un second ensemble de connexion.
