Exercise Physiology: Changes in Body Functions
Exercise can be categorized as light, heavy, or severe work. Light work requires up to 4 times the normal oxygen consumption, heavy work between 4-8 times, and severe work an oxygen consumption higher than 8 times the normal uptake (normal uptake = 3.5 mL/(kg·min)).
Energy Production During Exercise
As work increases, more ATP is required for muscle contraction. This can be produced via oxidative metabolism (Krebs cycle and ETC) or via anaerobic metabolism,

Understanding Physical Qualities
Endurance is defined as the capacity that allows us to maintain physical effort for a long time and recover more quickly afterward. Key elements that condition endurance include:
- Muscular System: Fast and slow-twitch muscle fibers, energy stores, and the ability to remove lactic acid.
- Nervous System: Coordination of different muscles performing the movement.
- Circulatory System: The amount of blood circulating through the body determines the ability to transport oxygen
Intervention and Prevention Programs for Substance Use
Intervention Programs
Program referral to primary care for cardiac reasons, tracking consumption of toxic substances, and psychological assessment to determine if intervention programs would apply. The National Plan on Drugs (PNSD) has different strategies for action against drugs, which can be classified into intervention programs and prevention programs. Due to the characteristics of this patient’s care, and given that the patient was referred by the Emergency Department (ED), they may not be a

Early Warning Signs and Educational Adaptations for Children
Warning Signs in Child Development
Alterations may relate to development in general, or specific patterns. These are indicative, so the final determination will be the work of a perceptual and motor specialist.
Developmental Warning Signs:
- Any type of deformation previously undetected.
- Clumsy and uncoordinated walking.
- Complaining of excessive fatigue when walking.
- Continued and charged tremor.
- Dubious or unsafe movements.
- Not measuring distances and often colliding with objects or people.
- Giving exaggerated
