Running Technique and Speed Development

Understanding the Running Stride

No two athletes run exactly the same way. However, we can distinguish athletes based on their running style. Running technique is based on biomechanical principles that enhance performance. Let's examine the key components of a stride:

• Stride: A full cycle from when the foot loses contact with the ground until it makes contact again. It consists of two steps.
• Stride Length: The distance between successive foot placements.
• Stride Frequency: The number of strides taken within a specific distance or time.

Phases of the Stride

1. Impulse: This phase results from the extension of the foot and knee, initiated when the hip drives forward. The opposite leg, the 'free' leg, folds up, creating

Key Definitions in Occupational Safety

Prevention of Occupational Hazards

A set of activities or actions taken or planned at all stages of the company's activity in order to prevent or lessen a worker suffering a disease condition or injury by reason or occasion of work.

Occupational Risk (Labor Risk)

The probability that a worker suffers an injury from work.

Risk

The probability that damage occurs and the severity of this, valued together.

Damage

Physical pathological disease or injury caused at work.

Prevention

A set of activities taken in all phases of company activity to avoid or reduce risks associated with work.

Protection

A set of activities and measures taken to reduce or eliminate the damage caused as a result of the accident. Protection measures...

Essential Anatomical Planes for Gymnastics

Understanding the important planes when working with gymnastics is crucial for proper form and movement execution.

• Frontal Plane: This is used by moving or passing in front of the body.
• Dorsal Plane: This refers to movements that occur behind the body.
• Sagittal Plane: These movements run through an axis dividing the body into left and right sides.
• Transverse Plane: Movements made parallel to the ground, dividing the body into head and feet sections.

Common Types of Body Movements

• Flexion: The approximation between two adjacent segments by decreasing the angle between them.
• Extension: The distance between two adjacent segments by increasing the articular angle.
• Supination: Lateral rotation of the forearm where

Basic Rules and Court Dimensions

Introduction: Volleyball is a team sport played by two teams of six players on a rectangular pitch of 18x9m, surrounded by a free zone of at least 3m. The court is divided into two equal areas by a central line, above which is the net. The net has different heights: 2.43m for men and 2.24m for women. Players occupy zones VI, V, IV, III, II, and I, following a specific rotation sequence.

Game Play and Scoring System

Considerations: A player (except the blocker) cannot touch the ball two consecutive times. The ball remains in play until it touches the floor, walls, ceiling, or another object, or until a player fouls. A point is scored by the team regardless of who is serving; if the ball falls into the opponent's...

Physical Education and Foundational Skills

Physical Education (P.E.) served in antiquity for activities like hunting and war. These skills must be based on a series of fitness components: Strength, endurance, flexibility, and speed. In modern times, these components remain important, as deficiencies can lead to health problems and reduced performance. All abilities require physical support, formed by physical qualities, which are the basic foundation upon which any skill is built.

Defining Physical Fitness

Physical Fitness is the result of the intentional development of physical qualities (PQ). The degree of physical fitness is the weighted sum of these physical qualities and their realization through the individual's personality.

What is Gestalt Psychology?

Gestalt is a German word meaning "form" or "shape." The Gestalt school of psychology posits that perception is holistic, meaning we perceive the nature of forms as a whole rather than just a collection of individual parts.

The Figure-Ground Relationship

The figure-ground relationship states that our vision always perceives a figure set against a background. The figure possesses its own characteristics, such as defined shapes and contours. A famous example of this is Rubin's Vase, which demonstrates the concept of reversibility between the figure and the background.

Laws of Stimulus Grouping

These laws describe the constant ways in which our minds group perceptual stimuli.

Advantages and Disadvantages of Using Floats

Advantages include quickly gaining confidence and learning quickly. However, a drawback is that overuse can hinder the adjustment process when removing the floaters.

Psychological Aspects of Pregnancy

Pregnant women often experience psychological changes, including:

• Cycles of anxiety throughout the pregnancy.
• A process of regression, which translates as childlike behavior (e.g., cravings or antojos).
• Nausea and vomiting, and increased sleepiness (due to internal changes).
• Dreams involving fear of dying during childbirth or having a sick child.
• Typical stress outlets.
• Anxiety related to unknowns: the sex of the child, the birth date, and breastfeeding.

Most Common Physical Complaints

Physical changes and discomforts frequently reported include:

• Cutaneous corrugation (skin changes) and stains/pigmentation.
• Digestive pain, muscular pain, and skin discomfort.
• Hemorrhoids and cramps.
• Significant physical changes: shifted

The Origins of Tennis

Tennis, as we know it today, was largely developed by Major Walter Clopton Wingfield in 1873, based on older racket games practiced by the Greeks and Romans. Wingfield introduced the first standardized rules for his game, which he called 'Sphairistike.' This early version established key elements, including the net and a scoring system where the first player to reach 15 points (or 'goals') while in possession of their service would win. Over time, organizations like the International Tennis Federation (ITF) have introduced changes, refining the rules, net height, and scoring, solidifying tennis as a major international sport.

Factors Affecting Electrical Shock Risk

Risk varies with age, sex, health status, and other factors. For example, women and children are often more vulnerable than men. This vulnerability is frequently attributed to differences in skin type and resistance.

Effects of Electric Current on the Human Body

The severity of an electrical shock depends heavily on the current intensity (measured in milliamperes, mA):

• 1 to 2 mA: Tingling sensation.
• 9 mA: Muscle contraction; the person can usually let go.
• 10 mA: Bearable pain threshold.
• 15 mA: Tetanization (involuntary muscle contraction). Stiff arm.
• 25 mA: Tetanization of chest muscles, potentially leading to asphyxia if prolonged.
• 50 mA: Ventricular fibrillation of the heart (requires immediate artificial respiration
