Jumping rope may reduce appetite
A simple childhood game may be more effective in fighting hunger than more ‘grown up’ workouts. A study published in the journal Appetite found that workouts that involve vertical movements – like jumping rope, for example – are more effective in staving off hunger than more conventional forms of exercise.
Many previous studies have shown that any kind of exercise suppresses appetite for at least a short period of time. But, researchers in Japan wanted to see if the ‘gut distribution’ that moves the center of mass up and down, which happens more dramatically during some workout than others, would change levels of the hormone ghrelin, which is released when the body is hungry.
So, for the study, researchers observed the appetite hormone levels of 15 healthy, young men while they jumped rope for 30 minutes, rode a stationary bike for 30 minutes and remained sedentary for 30 minutes. Each activity was done on a separate day. In addition to checking their hormone levels, the researchers also asked the men how hungry they felt, and what kind of food they craved at several points throughout the test period.
They found that the men reported feeling less hungry during and after 30 minutes of jumping rope than they did while cycling. They also had a reduced appetite for fatty foods while jumping rope than they did while they were cycling.
The study results suggest that while all aerobic activity can reduce hunger, activities that involve vertical movement may be more effective in suppressing appetite, and reduce the desire to overeat after workouts.
