Toddler Appearance vs. Newborn Appearance

A two-year-old is very different from a newborn baby, as the biological changes that occur in the first two years of a child's life are fast and spectacular. A newborn is about 51cm and weighs less than 4 kg. At two years, most children weigh over 13 kg and measure between 81 and 91cm, with boys generally having greater weight and height than girls. Moreover, the newborn is disproportionate, with a large head (one-quarter of body length). At two years, this proportion changes significantly.

Brain Maturation Indicators in Child Development

The maturation of the brain is responsible for increasing the regularization of sleep and wake rhythms in the child. It also drives changes in the child's ability to... Continue reading "Toddler vs. Newborn: Physical and Neurological Growth" »

Early Experiences

Early experiences, given the principle of life from the moment of fertilization, are very crucial for the organism because they occur when it is still undifferentiated. They are in critical periods of development of the individual.

• Pre-associative acquisition responses: Phenomena are habitualization, awareness, pseudo-knowledge, and inhibition.

The Learned

Almost all human behavior is learned. Man is learning all his life. It is said that a behavior is learned as a result of practice or experience and appears in the repertoire of behaviors in a more or less stable manner.

Learning is the acquisition or modification of behavior as a result of experience. The most important part of learning theory is the theory of information processing.... Continue reading "Understanding Early Experiences and Motor Learning" »

Physiological Rhythms and Mood

Physiological rhythm is the propagation of energy throughout the body, produced by the chain, succession, and differentiation of muscular work. A lively rhythm is rooted in our inner psychic and psychosomatic characteristics, but also depends on situational and environmental factors. External rhythms can organize the body in time and space simultaneously.

Types of Rhythm

• Monorhythm: maintains the same rhythmic structure.
• Polyrhythm: rhythmic variations in execution time. Facilitates the development of creativity.
• Arrhythmic: lacks a stable rhythmic structure; allows for further development of creativity and expressiveness.

Aerobics

Aerobics means "oxygen for life." First used by Pasteur (1875), the method was created... Continue reading "Physiological Rhythms, Aerobics, and Dance: A Holistic Approach to Movement and Well-being" »

Effective Basketball Defense Strategies

A. Single Defense

1) Defense Rated: Each defender is assigned to an attacker and only marks them.

It was not very efficient. Players were placed between the basket and the attacker.

B. Individual Defense Support

Every defender has to be aware of two references: the player with the ball and the player assigned to defend. The goal is to have more defenders than attackers in the vicinity of the ball (e.g., 5 defenders vs. 3 attackers).

Each attacker is linked by an imaginary line to the player with the ball (passing lane). The closer this line passes, the more pressure should be applied. Defenders are more buoyant when separated from the line.

C. Jump and Change (Unusual Defense)

One dribbling move. Attackers are... Continue reading "Effective Basketball Defense Strategies: Zones and Techniques" »

Understanding Human Movement

What Distinguishes Active Movement?

Active movements are voluntary actions produced by our internal forces (muscles) acting against an external force. They can be subdivided into:

• Free movement (no contest)
• Resisted movement (opposed by an external force)
• Helped movement (supported by an external force, such as a partner)
• Assisted-resisted movement (with both support and opposition)

Passive Movements

Passive movements are produced by an external force during muscular inactivity. This includes forced movement (something or someone causes the movement) or when voluntarily reducing internal forces to allow movement (movements produced by relaxation, such as when we lie down and relax our legs, and our feet fall out).

Physical Evidence in the 1st and 3rd Evaluation

Resistance

In the first evaluation, I achieved a mark of 8 periods, which was exceeded in the third assessment, reaching 10.5 periods. I believe this improvement is due to my increased physical activity during the course of this year. I usually ride a bike every afternoon I can, and I think that's one reason why I have increased my level of resistance. The test conducted to measure our endurance was a series of periods, which were measured by sounding beeps.

Abdominals

On this test, which involves performing as many sit-ups as possible in a minimal amount of time, I cannot say much because I don't even remember my mark on the first evaluation (17 abdominals). I do not show that... Continue reading "Physical Education: Tracking Performance Metrics" »

The Importance of Warming Up

Warming up is defined as preparatory activities aimed at activating the functional systems of the organism and preparing it for the subsequent application of more demanding loads.

Physiological Objectives

• Increase the temperature inside the muscle.
• Improve metabolic processes; organs of the body can produce energy more easily with the increase in temperature.
• Decrease muscle viscosity. The components of muscle coated with liquid at rest become less viscous when the muscle is heated.
• Increase the elasticity of muscle fibers.
• Increase enzyme activity.
• Increase vascularization (increased number of vessels supplying the muscle and greater blood flow), which achieves:
  • Improved oxygen supply.
  • Improved supply of nutrients.
• Facilitate

Qualities of Movement

The four factors that act on motion are: gravity, space, time, and flow.

Gravity

Any body is affected by gravity. It can, however, be used as an expressive element. There are two possibilities:

• In support of the gravitational force.
• Against it.

Space

The range of movement within the body also develops in space.

Movement Direction

• Direct: Movement in a single direction.
• Flexible or Indirect: Movement changing direction.

Movement Extension

• Constrained
• Large

Time

Every movement has a duration in time, as well as intensity, tone, and intention. There are two main types:

• Sustained movement: long, slow, continuous.
• Sudden or impulsive movement: short, fast.

These two modes connect the musical universe with the universe of body language.

Flow of

1. Flexibility

Flexibility is the physical quality that enables us to perform large-scale movements with any part of our body. It depends on:

• The ability to stretch the muscles
• The ability to move the joints

There are two types of flexibility:

• Dynamic: Exercises performed in motion. The movements should be broad and relaxed.
• Static: Maintaining a stretched position without movement. After taking the position, we should relax, breathe, and maintain that position for a moment.

2. Joints

Joints are connections between two bones that allow relative motion between them. They consist of:

• Articular surfaces of bones: Zones of contact between the bones forming the joint. They are covered with articular cartilage, which prevents chafing and allows slippage of

Bleeding and Hemorrhage Management

Bleeding, also known as hemorrhage, is the leakage of blood outside its usual circulatory vessels. Hemorrhages are classified into three main types:

• External Bleeding
• Internal Bleeding
• Externalized Bleeding through Natural Orifices

External Bleeding: Recognition and First Aid

In this type of bleeding, blood surges through a wound in the skin to the outside of the body.

Treating External Bleeding

The order of action for external bleeding must be followed carefully:

1. Apply direct manual pressure with gauze or a clean cloth. Never use cotton directly on the wound.
2. If possible, raise the bleeding area above the level of the heart.
3. If the above steps are insufficient, apply pressure on arterial sites along the path of the
