Although many studies have explored and verified the influence of chewing gum on human physiological function, these studies are all aimed at the static state of human body, and no research has paid attention to the possible influence of chewing gum on human walking, which is also the basis of this study.
Forty-six men and women aged 2 1-69 were recruited and randomly divided into two groups. In the first group of experiments, each subject rested for one hour, and then chewed two pieces of chewing gum (1.5g, 3000 calories each) 15 minutes while walking in a natural gait. In the control experiment, each subject also needs to rest 1 hour and walk 15 minutes, but the difference is that the subjects do not need to chew gum, but take powder with the same composition as chewing gum.
In each group of experiments, the researchers measured the subjects' resting heart rate, average heart rate during walking, walking distance and walking frequency. Calculate the average walking speed according to the distance traveled in 15 minutes, and estimate the step size according to the average walking speed and average steps. Finally, according to the average walking speed and weight of the subjects, the total energy consumption of the subjects during walking is estimated.
The results showed that compared with the control group, the changes of walking heart rate and walking and resting heart rate in the chewing gum group were significantly higher than those in the control group. The heart rate of the subjects in the chewing gum experimental group changed obviously at all ages, but compared with the experimental group in the control group, the average heart rate of the middle-aged and elderly people increased significantly when walking. Based on the experimental data of gender and age, the results show that chewing gum has the greatest influence on middle-aged and elderly men, and the heart rate and total energy consumption of middle-aged and elderly men have significant changes.
The author of this study concluded: "No matter how old you are, chewing gum while walking will affect a series of physiological and physiological functions. Our research also shows that chewing gum while walking can especially increase the walking distance and total energy consumption of middle-aged and elderly people. "
