Study Reveals Physical Decline Begins at Age 35, Highlights Benefits of Late-Life Exercise
A comprehensive Swedish study conducted over 47 years has revealed that physical fitness, strength, and endurance begin to decline around the age of 35. The research, part of the Swedish Physical Activity and Fitness study (SPAF), tracked several hundred individuals from ages 16 to 63, providing rare long-term data on physical performance. The study found that despite the natural decline, engaging in physical activity later in life can still significantly improve physical capacity. The findings emphasize that while physical decline is inevitable, exercise can slow the rate of decline, offering a 5-10% improvement in physical capacity for those who become active in adulthood.
