Sport and omega-3

According to the World Health Organisation (WHO) (1):

  • Adults aged 18 to 64 should do a minimum of 150 minutes moderate aerobic physical activity a week, or 75 minutes of vigorous aerobic physical activity a week, or an equivalent combination of moderate and vigorous activity.
  • The aerobic activity should be in sessions lasting a minimum of 10 minutes.
  • However, with the aim of obtaining even greater health benefits, adults in this age group should increase the moderate aerobic physical activity to 300 minutes, or up to 150 minutes of intense aerobic physical activity, or an equivalent combination of moderate and vigorous activity.
  • Twice a week or more, activities should be done to exercise the main muscle groups.

As well as the WHO recommendations, it is important to stress that there is significant scientific evidence on the relationship between physical activity and better health:

  • One of the clearest areas is cardiovascular protection, by reducing blood pressure or improving blood lipid levels with an increase in HDL (high density lipoproteins, commonly known as good cholesterol [2]) and a decrease in triglycerides (3).
  • Physical activity improves metabolic syndrome (3). Metabolic syndrome is a group of risk factors that increase the probability of cardiovascular disease or diabetes type 2 in an individual (4).
  • There is also evidence that exercise improves general mental health, reducing anxiety, insomnia and mood disorders (3).

Diet is also a fundamental element. Taking omega-3 produces a major direct benefit for athletes.

Why choose omega-3?

Omega-3 fatty acids have a recognised effect on:

  • Cardiovascular system, such as the heart and arteries, improving heart function.
  • Neurological system: omega-3 facilitates concentration, stimulates memory and improves mood and even vision (5-7).
  • Anti-inflammatory protection: recent studies indicate that supplementation with omega-3 fatty acids reduces muscle pain after intense exercise, a sign associated with local inflammation. In addition, omega-3 fatty acids can increase muscle strength and/or reduce fatigue, thanks to their anabolic properties in muscle tissue (8).
  • Respiratory system: omega-3 fatty acids can improve certain lung function parameters, such as forced expiratory volume in one second (FEV1), or forced vital capacity (FVC) (9).
  • Metabolism: omega-3 increases the metabolic rate and reduce fat mass (10).
