An important change that occurs with advancing age includes fat mass accumulation; currently 35% of Americans aged over 60 years are classified as obese. 1 This number and related complications are expected to increase as the world’s population ages. It’s well documented that obesity is

This study examined heart rate recovery (HRR) and heart rate variability (HRV) following maximal exercise in lean (<85th percentile age- and sex-BMI percentile; n = 11 (♂=5; ♀=6); 10.1 ± 0.7 years) and overweight (≥85th age- and sex-BMI percentile; n = 11 (♂=5; ♀=6); 10.5 ± 1.2 years) children.


Participants completed a 10-min rest, followed by a graded exercise test to maximal effort. HRV, in the time and frequency domains, was assessed during rest and recovery. Also during recovery, one-minute HRR and the time constant of a monoexponential line of best fit (HRRt) were determined.


There were no significant differences in one-minute HRR and HRRt between the lean (56 ± 7 beats∙min-1 and 160.4 ± 80.1 s, respectively) and overweight (51 ± 16 beats∙min-1 and 141.1 ± 58.1 s, respectively) groups. There also were no significant interactions between groups from rest to recovery for any HRV variables. Root mean square of successive differences (RMSSD) and high frequency power (HF) during recovery was 2.05 ± 0.49 ms and 3.30 ± 1.02 ms2 in the lean children, respectively. In the overweight children, RMSSD and HF were 1.88 ± 0.65 ms and 2.94 ± 1.27 ms2, respectively.


HRR and HRV findings suggest there are no differences in autonomic function during recovery from maximal exercise in lean and obese 8- to 12-year old children.

Obesity and associated chronic disease have increased at rapidly alarming rates over the last few decades. 1 More recently, researchers have also observed the negative impacts of obesity on psychological health and well-being, as obese people are more susceptible to an emotional disorder, social

Adipose infiltration in skeletal muscles of the lower extremity is linked to glucose metabolism and insulin sensitivity in adults ( 5 , 19 – 21 ). In the realm of insulin resistance in children, skeletal muscle is often overlooked despite the

Childhood obesity is a major public health concern, with obesity present in 1 in 5 preadolescent children (6–11 y old) and 13.9% of children ages 2–5 years old in the United States ( 14 ). Excess weight gain in childhood has a negative impact on long-term cardiometabolic health ( 12 ). Promoting

Most of the world’s population lives in countries where obesity kills more people than being underweight. Worldwide, the proportion of overweight people has nearly tripled since 1975, affecting up to 39% (1900 million) adults in 2016, from which 13% (650 million) were obese. 1 Obesity raises the

Pediatric overweight, obesity, and their multiple associated metabolic complications, are a public health concern, and their alarming progression supports the urgent need for new and effective preventive strategies and weight loss programs. As obese children and adolescents are now five times more

Obesity, a major public health problem worldwide, has been demonstrated to be associated with risks for numerous cognitive deficiencies, including deficiencies in executive functioning, attention, and visuospatial performance ( Liang, Matheson, Kaye, & Boutelle, 2014 ), as well as poor academic

Obesity is an important public health problem. It is associated with several chronic diseases ( 13 ) and causes about 3.4 million deaths worldwide ( 12 ). Globally, obesity has become pandemic across the life span ( 18 ). Specifically, among children and adolescents, the prevalence of obesity has

The know-how is available to reverse the obesity epidemic. Reversing obesity is a societal necessity because it is the predominant contributor to chronic ill health in developed countries and a growing precipitant of illness in middle and low-income countries. In the United States, for example, obesity is the chief driver of health care costs in a country that can no longer afford health care. Although some might advocate population-wide medication use to mitigate the effects of obesity on health, the more direct response is to end obesity. The goal of this paper is explain how mass-scalable obesity containment can be designed, built, and disseminated. Scalable Obesity Solutions (S.O.S.) are discussed from concept through deployment.
