Biological or Natural Methods

These methods strictly control birth without using any chemical or physical agents.

1. Coitus Interruptus

• Involves removing the penis from the vaginal canal before ejaculation.

Note: This method is generally not recommended as it can bring conflict and disruption to the couple. Confidence levels are often very low, as it requires full human self-control.

2. Periodic Abstinence or Rhythm Method

This involves avoiding intercourse during the woman's fertile period (ovulation).

• The menstrual cycle begins on the first day of menstruation and ends the day before the next.
• Ovulation typically occurs between days 12 and 16 of the menstrual cycle.
• This method varies depending on whether the menstrual cycle is regular or irregular.

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" »

Speed: Definition and Types

Speed is the physical quality that allows us to execute a movement in the shortest possible time. This quality is fundamentally an order transmitted from the nervous system to the muscle. There are different types:

Types of Speed

• Reaction Rate: The ability to respond as quickly as possible to a stimulus (e.g., a handball goalkeeper reacting to a shot).
• Speed of Movement: The ability to move from one place to another, traversing a distance in the shortest possible time (e.g., a speed racer).
• Speed Gesture: The quality that allows us to execute a specific gesture in the shortest possible time (e.g., a tennis player's serve).

Benefits of Speed Training

• The nervous system transmits the order of contraction (nerve impulse) to

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

Cougar (Puma) — Facts, Habitat and Conservation

El Puma

The cougar is a carnivore that is distributed throughout the Americas, especially in mountainous and forested regions.

It belongs to the Felidae family and can reach six feet in body length (excluding the tail) and about 65 inches at the shoulder.

It can jump thirty feet on level ground and up to 12 feet from the branch of a tree.

It has a flexible body that lengthens its stride; its muscles contract and stretch under the skin.

This is a quiet cat, moving stealthily and is the terror of animals such as goats, deer and elk; it also preys on mice, fish and birds. From the top of a tree it stalks its victims and jumps onto their backs, breaking their spines.

Mountain lions are born after a gestation... Continue reading "Cougar (Puma) Facts, Habitat, Behavior & Conservation" »

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
