Avoid Talking on Your Smartphone When You Are on the Treadmill

Poor cardiorespiratory fitness is associated with an increased prevalence of cardiovascular disease risks such as higher cholesterol and blood pressure levels.

Using smartphones as you run or walk on the treadmill lowers the intensity of the exercise, resulting in overall less health benefits, claims a new study.

The findings are important because poor cardiorespiratory fitness is associated with an increased prevalence of cardiovascular disease risk factors such as higher cholesterol and blood pressure levels, which could potentially lead to early death.

Workers On Treadmill Desks Perform Cognitive Tasks As Well As Those At Sitting Desks
The walkers showed slight decrease in processing speed, attention and typing words per minute but the overall drop was not enough to warrant major concern.

"Exercising at a lower intensity has been found to reduce the health benefits of exercise and fitness improvements over time," said researcher Jacob Barkley from Kent State University.

In the present study, 44 students participated in four, separate 30-minute exercise sessions on a treadmill.

The researchers assessed the effects of common smartphone functions such as music, talking and texting and a control condition where the students had no access to their smartphones.

Automated Treadmill Seamlessly Matches Your Pace of Walking or Running Outdoors
If you are running or walking on a treadmill and you want to speed up or slow down, then there is no need to push a button. It matches your speed on its own.

Using the phone exclusively for listening to music increased the average treadmill speed, heart rate and enjoyment of a bout of exercise.

Talking increased enjoyment, maintained heart rate but reduced speed.

Treadmill Desks at Workplace Offer Limited Health Benefits
Treadmill desks in the workplace offers limited health benefits to office workers, but can also pose logistical challenges that may not make such a program feasible for companies.

Texting reduced both speed and heart rate but it did not alter enjoyment.

It appears as if listening to music and, to a lesser extent, talking may have benefits on the duration and frequency of exercise owing to their ability to increase enjoyment.

Control Obesity: A Pill to Replace Treadmill
Researchers from Harvard Stem Cell Institute Harvard and Massachusetts General Hospital have recently revealed about a pill for obesity.

"However, if an individual’s opportunity for exercise is constrained by time, then it appears best to avoid talking on a smartphone during planned exercise," the authors said.

The researchers did not find any fitness-related benefits of texting while exercising.

"If one is looking to get the most benefits and improvements out of their workout, leave the smartphone in the locker room and enjoy your music with another type of device," the authors said.

The study was published in the journal PLOS ONE.
