Hormones involved in physical activity

Physical activity is an essential part of a healthy lifestyle. Whether running, lifting weights at the gym, or practicing yoga in your living room, your body undergoes a series of chemical and physiological changes. In large part, these changes are driven by hormones, small chemicals that act as messengers in the body. What are they and how do they influence physical performance and well-being?

  1. Adrenaline: The energy hormone

When you begin intense physical activity, your body releases adrenaline, commonly known as the "fight or flight hormone." Adrenaline increases heart rate and dilates the bronchi, providing more oxygen and energy to respond to stress. This is especially useful during exercise, as it allows you to make faster, more explosive movements.

  1. Cortisol: The stress hormone

Although cortisol has a bad reputation due to its association with chronic stress, it plays a fundamental role in the development of physical activity. During exercise, your cortisol levels increase to mobilize glucose into the bloodstream, thus providing a constant flow of energy to maintain activity.

  1. Endorphins: The hormones of happiness

Exercise triggers the release of endorphins, known as the "happy hormones." These chemicals have a natural analgesic effect and can generate a feeling of euphoria and well-being. Endorphins not only provide a feeling of well-being after a workout, but they also help relieve pain and reduce stress during physical activity.

  1. Growth hormone and muscle development

Resistance exercise, such as weight lifting, stimulates the release of growth hormone. This hormone is essential for muscle development and tissue repair. It helps increase muscle mass and burn fat, making it essential for those looking to improve their body composition.

  1. Insulin: Blood sugar regulator

Insulin is vital for transporting glucose to muscle cells during exercise. As physical activity increases, muscles need more glucose for energy. Insulin helps facilitate this process, ensuring that your muscles have access to the energy source they need.

  1. Leptin and ghrelin: Control of appetite

Hormones crucial to maintaining a healthy body weight. Leptin suppresses appetite, while ghrelin stimulates it. Regular exercise helps balance these hormones, which can lead to better appetite control and healthier food intake.

Hormones play an essential role in physical activity. From the adrenaline that gives an initial boost of energy. to the feel-good endorphins after exercise, these chemicals are an essential part of your physical experience. Understanding how these hormones work can help you optimize your training and maintain a healthy, active lifestyle.

Regular physical activity and a balanced diet are essential to maintain proper hormonal balance. Always consult a health professional before making significant changes to your exercise routine or diet to ensure you are making healthy choices for your body.
