Physiological Adaptations to Physical Training

Cardiovascular System

• Increased heart capacity, allowing the heart to receive and expel more blood.
• Strengthens and thickens the walls of the heart, allowing more blood output with each systolic contraction.
• Decreases resting heart rate, as the heart sends more blood with each beat, increasing the rest time between contractions.
• Improves the capillary network, allowing for better sanguineous irrigation.
• Increased amount of blood, red blood cells, and hemoglobin to carry more oxygen and nutritive materials (e.g., beneficial for marathon running, swimming, cycling, etc.).

Respiratory System

• Increased vital capacity (increased air capacity in the lungs, potentially rising from 3–4 liters to 6.5 L in a trained

Understanding Visual Disability

To better comprehend visual disability, it's important to distinguish between related concepts:

• Deficiency

  A loss or abnormality of psychological, physiological, or anatomical structure or function. Example: An alteration of the cornea.

• Disability

  A restriction or inability to perform an activity in the manner or within the range considered normal for a human being. Example: Difficulty distinguishing colors or judging the distance of objects.

• Handicap

  A disadvantage for a given individual, resulting from a deficiency or disability, that limits or prevents the fulfillment of a role that is normal (depending on age, sex, social and cultural factors) for that individual. Example: Being blind in a society not adapted for

Understanding and Training Endurance

Resistance is the ability to sustain effort, with varying intensity, over a prolonged period. To classify resistance, we consider two key concepts: muscle participation and energy production.

Muscle participation refers to the amount of muscle groups involved in the activity:

• General resistance: Involves most muscle groups in activities or exercises.
• Specific resistance: Involves specific muscle groups, such as arms, legs, or abs.

Energy production refers to the system by which the body obtains the necessary oxygen to produce energy in the muscle:

• Aerobic endurance: Occurs when sufficient oxygen reaches the muscle to produce energy.
• Anaerobic resistance: Occurs when the oxygen supply is insufficient for the intensity

Physical Conditioning

Physical Condition: The ability to perform daily tasks with vigor and effectiveness, delaying fatigue and preventing injury. This involves maximizing efficiency and minimizing energy expenditure. Basic physical conditions are: resistance, strength, speed, and flexibility.

Principles of Training

Principle of Adaptation

The human body can withstand physical activity and adjust to its practice. After running, the body undergoes wear that causes a momentary decrease in physical level. Later, the body recovers and reaches a new level, higher than the previous one (overcompensation).

Principle of Progression

The human body is capable of increasing efforts progressively. To achieve an increase in physical fitness, exercise must be... Continue reading "Baseball Fundamentals and Training Principles" »

Understanding Diet and Nutrition

Diet refers to the voluntary processes involved in choosing, preparing, and eating food, often influenced by affective factors. It is also a branch of medicine studying nutritional regimens.

Factors Influencing Diet

• Age
• Personal circumstances
• Type of activity
• Presence of disease

What is Nutrition?

Nutrition involves the exchange of matter and energy that every living being needs from the external environment to carry out life activities.

Key Nutrients

Nutrients are the components of food:

• Proteins
• Lipids (Fats)
• Minerals
• Carbohydrates
• Vitamins
• Water

Balanced Diets and Menu Planning

A balanced supply involves consuming nutrients in the most suitable proportions and distributing them according to individual characteristics and needs.... Continue reading "Child Nutrition: Needs, Habits, and Common Issues" »

Assessing the Need for Mobilization

In many cases, victims do not fully recover from initial first aid. It's often appropriate to consult professional services to confirm the best course of action. When deciding whether to evacuate to a hospital emergency room, determine if it's appropriate to wait for emergency services or if it's preferable to move the person to a safe location.

Improper handling and transport can aggravate injuries, especially fractures that could become open fractures if not handled correctly.

The recommended action sequence is:

1. Perform an emergency assessment and take appropriate actions on site.
2. Stabilize vital functions.
3. Decide whether to wait for emergency services or transfer the person to a hospital.
4. Place the person in

Basic Physical Features

Basic physical features determine the capacity or general fitness of an individual, and training allows room for improvement.

Basic Qualities

Basic qualities are indispensable and participate in most physical activities. Within these, we find strength, speed, endurance, and flexibility.

Complementary Qualities

Complementary qualities must be present in any physical activity, but they are not as indispensable.

Derivative Qualities

Derivative qualities are produced as a result of the conjunction of various basic and complementary physical qualities. Examples include power and agility.

What is Strength?

Strength is the ability to generate muscle tension. It is the ability that is acquired the fastest but also the most easily lost.... Continue reading "Understanding Physical Fitness: Strength, Speed, and Endurance" »

Definition of Judo

Judo is a combat sport based on self-defense, in which each competitor uses their opponent's strength to project them onto the ground, immobilize them, or force them to give up the struggle through a joint lock or strangulation.

Two Fundamental Principles

• The Principle of Efficient Use of Energy: Judo movements performed correctly represent the minimal use of physical and mental energy. For example, most fighting techniques exploit the opponent's weight to unbalance or throw them.
• The Principle of Mutual Prosperity and Friendship: For Jigoro Kano, the harmonious development of human beings is only possible through the concessions granted by people themselves.

Fighting Area and Rules

Fighting takes place on a tatami. In the case... Continue reading "Judo Basics: Rules, Principles, and Terminology" »
