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

Reflect on Consequences of Changes in Vt

The volume of air inspired with each breath is called the current and is symbolized by V_T (Tidal Volume). In an average individual at rest, the V_T is 500 ml.

Resting expiration is passive, occurring because the inspiratory muscles relax. This relaxation always returns to the same level, making the resting expiratory line fairly even, hence its name. Inspirations can vary in magnitude, so lung volume is defined relative to this established resting line.

Key Respiratory Volumes

• Tidal Volume (V_T): The volume that enters or leaves the airway during a normal respiratory cycle.
• Inspiratory Reserve Volume (IRV): The maximum volume that can enter the airway after a normal inspiration.
• Expiratory Reserve Volume (ERV)

New School and Pedagogical Renewal: John Dewey (1859-1952)
Father of progressive psychology, John Dewey critiqued traditional education and emphasized the importance of experience in learning. He proposed a dynamic conception of education that rejects the notion of education as merely the training of intelligence. Dewey's problem-based methodology consists of five phases:

• Identifying a problem or difficulty.
• Starting the experience.
• Inspection of available data and research of viable solutions.
• Formulation of hypotheses for solutions.
• Checking the hypotheses.

Maria Montessori (1870-1952) worked extensively in scientific teaching and inaugurated the first Casa dei Bambini in San Lorenzo, Rome. She focused on children aged 4 to 5 years, allowing them...

Defining Games and Sport: Key Concepts

What Constitutes a Game?

A game is characterized by motor and social activity. It involves constraints such as the possibility of winning or losing, the existence of rules, and real motor actions. These are recreational activities with significance, requiring a sufficient degree of motor system involvement, including key movements related to intention, decision, and motor adjustment to the environment and others.

Scholarly Perspectives on Games vs. Sport

• Sanz: The game originates from a popular proposal. It is communicative, creative, spontaneous, and perhaps detached from serious outcomes. Conversely, proposals directed towards higher authorities (possibly organized sport) are competitive, potentially alienating,

Hand Tool Safety and Proper Use

Wrenches

Types of Wrenches

• Fixed Wrenches: Open-end, box-end, tube, star, glass, Allen, Torx.
• Adjustable Wrenches: Adjustable spanners, pipe wrenches.

Correct Use of Wrenches

• Hold the workpiece firmly with the bolt head or nut to prevent slipping.
• Use your fingers to pull the wrench, never grasp the tool with your entire hand.

Actions to Avoid with Wrenches

• Never strike the tool to loosen or tighten.
• Do not grasp the tool with your whole hand (implying improper grip).
• Never splice two wrenches together to create additional leverage.

Adjustable Wrenches

Proper Use of Adjustable Wrenches

• Push with the palm of your hand.
• Always wear appropriate gloves.

Common Deficiencies and Hazards

• Worn, bent, or damaged clamping jaws or handles.

Physical Conditioning Components

Warming Up: Preparation for Effort

The warming up is a physical activity that involves the gradual and progressive mobilization of all the muscles and joints to carry out intensive efforts without injury and maximize performance. Thanks to it, body temperature rises, blood supply improves, neuromuscular coordination increases, and cardiac efficiency is enhanced.

Warming up may be:

• Active: Done at the start of any session of physical activity or sport.
• Rehabilitation: Used to warm the affected muscles after suffering an injury.
• Distance: Used in long-term competition and performed a few hours earlier.
• General: Utilized for general activities.
• Specific: Concerns only the muscles to be engaged in physical activity.

Understanding Employment Contract Types

Indefinite Contracts

Indefinite contracts are those that do not specify a completion date. These contracts often aim to promote the stable placement of specific groups affected by unemployment and job instability.

Fixed-Term Contracts

Fixed-term contracts are characterized by having a predetermined end date. Several types fall under this category:

• Work and Service Contracts

  These contracts are for a specific work or service, carried out with autonomy and substantive independence within the normal business activity. Their execution time is limited to the duration necessary for the completion of the work or service. If the contract exceeds one year, a written denunciation (notice of termination) is typically

Fundamental Geometric Elements

• Point: Has no dimensions and is determined by two intersecting lines.
• Line: A point in motion. If the direction remains constant, it is a straight line; if it changes, it is a curve. Lines have one dimension: length.

Types of Lines

• Straight Line: Generated by a point moving in a constant direction. It has unlimited length, and its points are aligned.
• Ray: Any point P on a line divides it into two parts called opposing rays.
• Segment: A part of a line bounded by two points.
• Curve: Generated by a point moving while constantly changing direction. It has unlimited length.
• Arc: A piece of a curved line bounded by two points.

Planes and Volume

Plane

A surface formed by a straight line moving in a direction other than its own. It...

Sports Psychology in Chile

1st Period (1970-1979): Early Stages

• 1972: Creation of the Chilean Society of Sports Psychology, but it was not active.

2nd Period (1980-1994): Individualism

• Sports psychologists worked independently.

3rd Period (1995-2001): Association

• 1992: Enrique Aguayo became president of the Chilean Society of Sports Psychology (SPS) and promoted association among sports psychologists.

The Human Element in Traffic Accidents

The human element in road safety can be analyzed from two distinct points of view: first, as an element that must be preserved from suffering damage in traffic accidents, and secondly, as a decisive factor involved in causing those accidents. Man is the element who directly controls the vehicle as the active participant in the accident, while also indirectly influencing the physical environment. Everything is closely related to human reaction time.

Driver Skills and Behavior

Within educational and psychological frameworks, we note two types of skills:

• Natural skills: Physical or intellectual abilities that are acquired effortlessly.
• Technical skills: Abilities acquired through practice and psychological study.
