A groundbreaking new study highlights that not just the amount, but the timing and regularity of physical activity are decisive in maintaining and improving VO2 max—a key measure of cardiovascular fitness—among older adults. This research, which analyzed nearly 800 people aged 70-plus, suggests that consistent activity, particularly in the morning, can have profound effects on healthy aging and longevity—a message with growing relevance for Thailand’s rapidly aging society (Runner’s World).

A groundbreaking study has highlighted timing and consistency of physical activity as the leading factors for increasing VO2 max—the core marker of cardiorespiratory fitness—as people age. The findings, published in the prestigious journal Medicine & Science in Sports & Exercise, are especially relevant for older adults in Thailand, where the aging population is expanding rapidly and public health efforts increasingly focus on healthy aging.

VO2 max, the measure of the maximum amount of oxygen the body can utilize during intense exercise, is more than just a benchmark for athletic performance. Across global research, it’s recognized as a powerful predictor of health span and longevity; higher VO2 max values are linked with lower risks of disease and longer, healthier lives. For Thais keen to maintain vitality and independence as they age, understanding how to optimize this measure is of growing importance (AOL article).

A landmark study published in Medicine & Science in Sports and Exercise suggests that the timing and consistency of daily physical activity can significantly influence heart and lung health as people age. The research, which focused on older adults, provides compelling evidence that working out earlier in the day – and sticking to a regular exercise schedule – may provide substantial benefits for cardiorespiratory fitness and walking efficiency, two critical markers of healthy aging (Medical News Today).

The well-held belief that physical fitness in youth directly causes a lowered risk of early death is being challenged by new research from Uppsala University, which suggests that the true relationship between fitness and mortality may be far more complex than previously thought. The findings, published in the European Journal of Preventive Cardiology, reveal that even random factors—such as accidents—show similar associations to fitness and premature death as diseases, raising questions about the validity of past conclusions on the protective effects of fitness alone.

A new wave of scientific insight has highlighted a dilemma familiar to every runner: when exhaustion sets in, is it your legs giving out first or your lungs and heart? The answer, experts say, could fundamentally alter the way athletes and casual joggers alike structure their training programs, and the latest research underscores the importance of accurately identifying the source of fatigue to improve running performance and overall health (Runner’s World).
