Preguntas científicas en Educación Física
As a Physical Education teacher, one of my main goals is to provide practical tools to my students for shaping their future in terms of health and fitness.
A primary concern in this regard might be an excessive focus on theoretical information we provide them, neglecting the necessary time for physical activity during the week. To address this, it is preferable to convey information through a question-based system.
Each week, a til the next class to provide an answer. question related to health or fitness is posed, based on scientific research or interesting material. They have until the next class to provide an answer.
If the following week they have the answer (even if only one), they will have 5-10 minutes of free play every day of that week (adjustable). juego libre todos los días de esa semana (ajustable).

How is it Applied in Your Class?
In my own experiences, I have carried it out with 12 to16 years old students.
The reward for the question can vary depending on the class characteristics. A point system can be established and reward students who get involved individually. Although I recommend that it be group-based.
The key to the project is that the question arouses the interest of the students. Below you can find a battery of questions to start with. de los alumnos. A continuación puedes encontrar una batería de preguntas para empezar
Questions and Answers
QUESTION 1.
COLD EXPOSURE
- 15 years
- 16 years
What specific action can we perform on a normal day that provides us a significant and LASTING increase in dopamine (2.5 times)?
Many things can induce increases in these levels, such as listening to music, eating chocolate, or watching a favorite TV series. However, these stimuli usually result in very brief increases, lasting only minutes, and in some cases, possibly seconds (like chocolate or nicotine).
ANSWER 1
Cold Exposure.
When we voluntarily expose ourselves to cold, like taking a cold shower or a cold water bath (1 to 3 minutes), our dopamine levels increase by 2.5 times, and this effect can last from 3 to 4 hours.
If you want to try the experience (safely) here is a protocol from Andrew Huberman, a professor at Stanford University: video.

QUESTION 2.
BREATHING AND JAW
- 12 to 15 years
- 16 years
¿Cuáles son los motivos por los que cuando se descubren tribus no contactadas (en el Amazonas, por ejemplo), o cuando se estudian los restos de nuestros ancestros de hace miles de años, todos tienen dientes perfectos, mientras que la mayoría de nosotros tenemos que usar aparato?
One is diet (soft food + sugar), we are looking for another.
ANSWER 2
Nasal Breathing
«"Breath" by James Nestor.» de James NestorThis book discusses the origins of mouth breathing, its effects, and how to address it. He speaks from his own experience. He had health problems related to his way of breathing. He underwent an experiment in which his nose was blocked for three weeks. In diary form, he recounts the changes his body and mind experience during the process and how he recovers after completing the experiment.
«"Jaws: The Story of a Hidden Epidemic".I haven't read this one yet, but it reports cases by experts from Stanford University. Like the one of two twins separated at birth::
One of them was raised in a modern society. The other in a wild environment. The one raised in the wild, chewing meat and bones, had developed a perfect jaw and "beautiful" facial features. The one raised on soft foods and sugars had a retracted jaw and underdeveloped facial features.
QUESTION 3.
ALKALINIZATION OF THE BLOOD
- 16 years
Can we naturally alkalize our blood?
Requires knowing what alkaline or acid means in relation to the blood (perhaps this should be a previous question).
ANSWER 3
Yes, we can. Whether our blood is acidic or alkaline depends on the amount of CO2 circulating in it. Often, the main reason for high levels of CO2 is our way of breathing.
The positive aspect of this is that in most cases, we can control it. To do this, we must learn to breathe correctly. esto es que en la mayoría de casos, podemos controlarlo. Para ello debemos aprender a respirar correctamente.
When we are stressed or feel anxious, we tend to take short, very frequent breaths and do not exhale as much, without realizing it.
This causes us to accumulate CO2. A quick solution in these situations can be the double inhalation technique. Here is an explanation of what it is and how to do it. (Never do it in an uncontrolled manner).
Double inhalation:
- Technique: https://www.youtube.com/shorts/9JhTMTksk9s
- Explanation:
"One of the rarest and most admirable human qualities is: the self-regulation of autonomous awakening. (It reflects top-down prefrontal-limbic control). It equates to: greater focus, precision in speech and actions, and perseverance in all efforts. It is evident when it is present or absent.
The physiological sigh: two deep inhalations through the nose (without exhaling between them), followed by a complete exhalation to empty the lungs (through the mouth) is the fastest way to reduce autonomous awakening, that is, to 'calm down,' and triggers the activation of specific neural circuits for calmness.
This 'double inhalation, prolonged exhalation' approach is based on studies exploring the activation of brainstem neurons that express specific neuropeptides and promote the activation of a neural circuit that connects the brain and body, predisposing us towards calmness (Li et al., Nature 2016)."
If someone wants more information about their way of breathing, they can take the following CO2 tolerance test.
WARNING: Sometimes breathing exercises can make you dizzy. If you are going to try any related exercise, inform someone at home what you are going to do.

QUESTION 4.
CO2 IN HIGH-LEVEL COMPETITIONS
- 12 to 15 years
- 16 years
In previous scientific research, it was found that NBA basketball players experience a significant decrease in their performance during the fourth quarter of the game due to an external factor. What is the reason for this phenomenon?
Key information: We are not looking for things like pressure, fatigue, etc.
QUESTION 4.
CO2 accumulation in the stadium.
Since NBA stadiums are not open, CO2 tends to accumulate. as there are thousands of people breathing inside. During the fourth quarter, this accumulation becomes significant and can affect the players' performance, as they breathe air with a high concentration of CO2
