Strength Training for Cyclists: More Watts, Not More VO2max
Heavy strength training can improve cycling efficiency and anaerobic power without raising VO2max. Here's what cyclists should lift, and what the evidence cannot prove.
Can an Active App Improve Fitness With Sleep Apnea?
Passive tracking has not improved fitness in obstructive sleep apnea. A 2026 review finds active, goal-based apps can raise measured activity and VO2max in trials.
Teen Fitness, BMI, and Severe Infection Risk Decades Later
A million-man Swedish cohort links low teen fitness and higher BMI with later sepsis, pneumonia, and endocarditis—without proving that either causes it.
Cardiorespiratory Fitness and Mortality: The Dose-Response
Cardiorespiratory fitness and VO2max predict mortality in large cohorts. Learn the per-MET gradient, who benefits most, and where the evidence has limits.
