Arabic version: دراسة تربط توقيت التمارين بتحسين صحة القلب

Health researchers suggest that exercising in sync with your natural body clock can enhance the benefits of physical activity. A study published in the journal Open Heart indicates that early risers, or “larks,” should work out in the morning, while night owls may benefit from evening sessions. This alignment could lead to significant heart health improvements, particularly for individuals at higher risk of heart disease. According to BBC News, participants in the study experienced better sleep, reduced blood pressure, and healthier blood sugar levels.

The study involved 134 participants in their 40s and 50s in Pakistan, all possessing at least one heart risk factor, such as high blood pressure or being overweight. They engaged in supervised brisk walking on a treadmill for 40 minutes daily, five times a week over three months. Based on their chronotype, 70 were categorized as morning larks and 64 as night owls. Those who exercised according to their body clock reported greater improvements in health metrics compared to those who did not.

Researchers highlighted that the body’s internal clock influences sleep-wake cycles, hormone levels, and energy, which can affect exercise performance and adherence. They noted that a “one-size-fits-all” approach to exercise timing is ineffective, particularly for night owls who may face increased heart risks if forced into early morning workouts.

Hugh Hanley, head of personal training at PureGym, noted a shift in exercise patterns, with people increasingly prioritizing health and flexibility in their training schedules. He emphasized that consistency is crucial for fitness, advising individuals to set manageable goals rather than overwhelming targets. The current trend shows a rise in strength training across all age groups, particularly among younger individuals.

Dr. Rajiv Sankaranarayanan from the British Cardiovascular Society supports the study’s findings but calls for further research to confirm the benefits of timing workouts according to body clocks. Dr. Nina Rzechorzek from the University of Cambridge added that while timing is important, regular exercise remains the key to health. The NHS recommends incorporating strength training and vigorous cardio into weekly routines for optimal health benefits.
