From record-breaking running speeds set by a 91-year-old to how your body responds to climate shifts, the American Physiology Summit brought together researchers exploring the science  of health and life itself. Here’s how their findings presented at the annual meeting of the American Physiological Society could shape your daily routine—and your future.

How Does She Run So Fast? Examining the Muscle Composition of a 91-Year-Old World Record Sprinter

A woman smashed a longstanding world record in the 200-meter sprint at the age of 91, prompting scientists to delve into her physiology to learn how she can run so fast. Understanding her physiology may help all of us maintain strength as we age.

Email Nudges Help Boost Exercise Capacity for People with Parkinson’s Disease

People with Parkinson’s disease who received a weekly email newsletter with Parkinson’s-specific exercise tips saw a significant improvement in exercise capacity. This low-cost strategy could support better health for people with chronic conditions.

Planning to Hit the Bars? Be Sure to Hit the Gym First

Daily aerobic exercise could help to counteract some of the negative impacts of college-age drinking later in life. Scientists found physical activity acts as a buffer, protecting against future health risks.

Climate

Viewing a Hot Virtual Environment Helps the Body Cool Off During Exercise

Watching warm weather virtual reality scenes rather than cold scenes during exercise increases sweating, helping the body cool down more efficiently. This could improve how our bodies perform in the heat.

Heat Really Does Feel Hotter After a Cold Season

We gradually lose our tolerance for heat during the winter but can regain it with a brief regimen of hot and humid workouts. Short-term exposure to heat can help prepare you for summer.

Diet and Nutrition

Could Potassium Be the Antidote to Too Much Salt?

Eating more potassium could help salt-lovers dodge some of the dangers of too much sodium. This could reduce the harmful effects of sodium on heart and kidney health.

Compound in Tomatoes May Help Stave Off Weight Gain

Lycopene, the compound that gives tomatoes their red color, supports healthy liver functioning and may help prevent weight gain. Scientists say lycopene supports a healthy metabolism.

Popular Sugar Substitute May Harm Brain and Heart Health

Erythritol, a commonly used sugar substitute often marketed as “healthy,” may impair blood vessel health by disrupting the brain’s ability to produce a critical compound. The findings suggest it could interfere with how blood vessels work.
