The Pressing Need for Sports Medicine in Motorsports
Automobile racing is one of the largest spectator sports in the world, with a viewing audience equal to that of soccer, and most people, regardless of their interest in the sport, can name famous race events like the Daytona 500 or Indy 500 and drivers like Jeff Gordon, Mario Andretti or Lewis Hamilton. The popularity […]
Overall Physical Activity or Intensity of Activity: Which Is More Important for Cardiometabolic Health?
Cardiometabolic risk describes a collection of factors known to increase the likelihood of cardiovascular disease. It includes lipid and glucose metabolism as well as adiposity and hypertension. We know that being more physically active is associated with lower cardiometabolic risk. However, it is not clear whether more specific or tailored physical activity guidance can be […]
Resistance Exercise Increases Gastrointestinal Symptoms, Markers of Gut Permeability, and Damage in Resistance-Trained Adults
Gastrointestinal (GI) discomfort can occur as an unfortunate byproduct of physical exercise. While this phenomenon has been thoroughly outlined in endurance athletes, only one study to date has measured and reported increased markers of GI injury following resistance exercise that coincided with decreased nutrient absorption. Grand View Market research estimates the global digestive health market will reach […]
Can Diet Help Athletes Manage ADHD?
As a sports nutritionist, I commonly counsel athletes who have Attention Deficit Hyperactivity Disorder—generally referred to as ADHD (or ADD). ADHD is characterized by hyperactivity, impulsivity, and/or inattention. It affects 4-10% of all American children and an estimated 4.4% of adults (ages 18-44 years). ADHD usually peaks when kids are 7 or 8 years old. […]
Adolescents with Sport-Related Concussion Recover Faster When They Adhere to an Aerobic Exercise Prescription
Patients with sport-related concussion have traditionally been advised to employ strict physical and cognitive rest until all of their symptoms resolve, i.e., until they become asymptomatic. This “cocoon therapy” was based largely upon animal research showing that early uncontrolled physical activity delayed recovery from simulated concussion. Emerging evidence over the past decade, however, demonstrates that there is […]
Physical Activity in School-Aged Children
School-aged children should get at least 60 minutes of moderate- or vigorous-intensity physical activity every day of the week. Only 26% of adolescents met these physical activity guidelines in 2018, and that percentage has remained stable since 2011. The COVID-19 pandemic made it even more difficult for children to meet these guidelines. Despite knowing the risk of sedentary behavior […]
Does Working Out Result in T Cell Mitochondrial Gains?
The positive effects of aerobic exercise training on skeletal muscle metabolism are well recognized. Exercise also leads to beneficial metabolic adaptations in other organs, including the brain, liver, kidneys and adipose tissue. However, the effects of exercise on immune cell metabolism are largely unknown. Immune cells that circulate throughout the body are exposed to exercise-associated […]
Are You Prepared for a Cardiac Emergency?
The benefits of physical activity, even at low levels, far outweigh the cardiovascular risks for most people. But Murphy’s Law is always peering around the corner — what if the worst happens? We need to have a plan in place. Fortunately, ACSM’s consensus statement on the topic provides fitness professionals with important background information and a number […]
Vertical Loading Rate Should Not Be Used as a Predictor of Running Injury
Running is a popular form of exercise due to its health benefits and low economic cost; however, the prevalence of running-related injuries is on the rise. With most running injuries classified as overuse injuries due to excessive, repetitive loading, clinicians and researchers are looking to develop measures of this loading to assess a runner’s injury […]
Meeting the 50th Percentile for 24-hour Movement Helps Cognitive Function
Alzheimer’s disease and related dementias are debilitating conditions leading to impaired cognitive processes and worsening physical functioning. They place significant burden on caregivers and health care systems. Roughly 15 million cases of cognitive impairment and Alzheimer’s disease in the U.S. are projected by 2060. While there are no medical treatments to delay Alzheimer’s disease progression, […]
