Whether on a crowded Eastern seaboard boardwalk, a sunny California ocean promenade or a meandering walkway in Des Moines, Iowa, if there are long stretches of smooth pavement, you will find in-line skaters wending their way gracefully, their fast-moving rhythmic motion leaving joggers and cyclists in the dust. The smooth gliding movement may appear effortless, yet rollerblading is one of the most challenging cardiovascular activities around.
So is rollerblading a good cardio exercise?
Cardiovascular Exercise and Muscle Action
Cardiovascular exercise is marked by rhythmic aerobic muscle action that demands oxygen to regenerate adenosine triphosphate, or ATP, the source of muscular contraction. The ongoing demand for oxygen increases the speed and depth of respiration and makes the your pump faster and harder to deliver oxygen-rich blood to your working muscles. The greater the size and number of muscles involved in an exercise, the greater the demand on your cardiovascular system.
Rollerblading gives the large muscles of the lower body an amazing workout, their perpetual contraction placing a substantial demand on your cardiovascular system for a steady supply of oxygen. The abductors of your outer thigh, the adductors of your inner thigh, the quadriceps, hamstrings, gluteus maximus and the gastrocnemius of your calf are all active participants.
Exercises like rollerblading that require you to continually correct your balance require stabilizing action by your core muscles to reestablish your center of gravity, making in-line skating an excellent exercise for your abs. While the large muscles of your upper body are not directly involved in locomotion, they participate to a lesser extent as stabilizers.
