Lighting and Exercise: Study shows what the connection between them is

Have you ever thought about the effect of lighting on exercise? Regarding the period of the day, evidence He investigated whether the time of the day affects the degree of healing in physical performance.It shows a simple “as much as possible” exercise in metabolism or health consequences. What about artificial lighting environments? A new study began to illuminate the roads related to the subject.

In recent years, while passing through more than 50 gyms, exercising to analyze myself, I realized that contemporary academies have a common feature: Low brightness. The trend is completed with loud sound and neon lights, especially in sports network franchises. Until then, the effects of brightness on the body’s responses to exercise were unknown. My hypothesis was that low lights could be negative for our practitioners, but my perception was at least wrong from the physiological perspective.

In order to investigate the subject, a study was conducted by the researchers of the University of São Paulo University (USP) Motor Activity Hemodynamic Laboratory (Campaign). Cardiovascular recovery was investigated after blood pressure reactions and exercise. For this, 20 men exercised in two environments: one has high (5,000 luxury) and the other low brightness (

How was the study

After arriving at the laboratory, the participants took a snack for two cereals and 100 ml of water (to prevent possible variations at pressure) and lay for 45 minutes exposed to low or high light. After this period, they rose and sat on the exercise bike for 40 minutes to pedal at medium intensity. In all these moments, blood pressure and heart rate were measured.

A phenomenon that occurred after exercise Decreased blood pressure compared to the pre -exercise periodWhat we call hypotension after exercise. This is a positive response especially in hypertensive individuals who can use exercise as a blood pressure control. The effect can last up to hours after training by characterizing exercise as a drug.

Is it high or low light?

However, this result was observed only in the conditions of weak light, because there was an excessive increase after the exercise shown by systolic blood pressure levels before and after exercise, without being exposed to high brightness.

The combination exercise and intensive light eliminated the decrease in diastolic and average blood pressure 30 minutes after exercise and supported an average increase of 2 and 3 mmHg, respectively, 60 and 90 minutes after the exercise. After 1 and a half hours of exercise, only the average blood pressure increased when practitioners were under strong lights. When the participants did in a dark environment, blood pressure decreased after 30 minutes of exercise.

In addition, there was an excessive load of cardiac operation evaluated by the double product – the heart rate product with systolic blood pressure in super open environment.

Obviously, academies that use low lighting do not do for the benefit of the practitioners in this research, on the contrary, the tendency aims to create discomfort, so that the practitioners should not remain in place, because the constant search for profit speaks loudly.

If the intense light has an effect on an exercise benefit, we can begin to rethink the application environments and properties. However, this was only the first work in the region, and in order to verify the result, new researches need to be conducted and published. Since the investigation only takes place with aerobic exercises and men, we do not know if there is an effect on the measurements of bodybuilders.

Another thing that needs to be investigated is the subjective comfort of practitioners who can offer differences between individuals under the conditions of shine conditions different from the psychological perspective. Let’s wait for new science lights on the subject.
