A recent study from the University of Jyväskylä in Finland has challenged the conventional belief that running is a key method for weight loss. Instead, the research suggests that while running may not significantly contribute to weight reduction, it can effectively prevent weight gain over a person’s lifetime. Published in Frontiers in Sports and Active Living, the study indicates that older sprinters and endurance athletes exhibit less fat mass compared to their younger counterparts, who tend to prioritize strength training.
Running vs. Resistance Training: Insights from the Research
The findings highlight the advantages of resistance training in preserving muscle mass. The study revealed that individuals who engaged in resistance exercises consistently throughout their lives maintained muscle mass more effectively than those who relied primarily on sprinting and long-distance running. Interestingly, older individuals who focused on strength training demonstrated comparable muscle mass to younger individuals involved in similar activities.
Kelsey Costa, MS, RDN, a registered dietitian nutritionist and founder of Dietitian Insights, discussed the implications of the study, stating that while running promotes overall health, its impact on weight loss is often overestimated. According to Costa, the body’s adaptive mechanisms play a crucial role in this phenomenon. She explained that the hypothalamus, which regulates metabolism, establishes an energy expenditure target as a physiological safeguard against starvation, highlighting the complexity of weight management and the body’s instinct to maintain homeostasis.
The Importance of Prevention and Comprehensive Strategies
Costa emphasized that preventing weight gain is critical for maintaining a healthy body composition. However, she pointed out that effective strategies exist for losing fat while simultaneously increasing lean mass.
Dr. Ari Jonisch, President of Main Street Radiology and Chief-of-Service at New York-Presbyterian/Queens, reinforced the study’s findings by advocating for a holistic approach to weight loss. “Regular physical activity, such as running, is vital for overall health, but dietary choices are essential for creating the necessary calorie deficit,” he explained. He recommends a balanced diet rich in whole foods, lean proteins, fruits, vegetables, and complex carbohydrates to complement any exercise routine.
Integrating Strength Training for Optimal Results
To further enhance weight loss efforts, Dr. Jonisch suggests incorporating strength training into fitness regimens. He notes that this practice not only aids in building muscle mass but also boosts metabolism, thereby supporting weight loss goals.
As the findings from this study continue to reshape the conversation around running and weight loss, experts advocate for a balanced approach that combines dietary awareness with regular physical activity and strength training to achieve sustainable health outcomes.
