Understanding the Curriculum Project (PCC)

The Curriculum Project (PCC) aims to define a flexible, versatile, and constantly revised range of training for an academic center. It enables innovation in curriculum definition, teaching style, and methodology.

PCC: Preparation and Approval

While the School Board is the decision-making body that can opine on the PCC's validity (including its integration within other institutional documents), the technical and practical responsibility for its development and implementation rests with the teachers and the faculty (cloister).

What is the Curriculum Project (PCC)?

The PCC represents the comprehensive training and academic offerings of the center. It develops the typical elements of a curriculum design and... Continue reading "Curriculum Project (PCC): Purpose and Key Elements" »

Trapezius Muscle

The trapezius muscle is a large, superficial muscle that extends from the skull to the last thoracic vertebra and laterally to the spine of the scapula. It occupies the center of the spine on both sides. Although often described as trapezoid-shaped, it is actually triangular. The appearance of a trapeze comes from the combination of the two trapezius muscles.

Sternomastoid Muscle

The sternomastoid muscle is located at all levels, running from back to front. It originates at the mastoid process of the temporal bone, immediately behind the external auditory meatus. One muscle belly terminates at the sternal manubrium, while the other terminates at the upper middle third of the clavicle, leaving a space between them. It acts as an...

The Force and Muscle Strength

The force is the capability that allows a person to create muscular tension in order to overcome an overload. Muscle strength can manifest itself in different ways:

Types of Muscle Strength

Peak Force

Peak force: the tension the muscles must generate to overcome a maximal opposition. Weightlifting (halterofilia) is an example of work that develops peak force.

Power or Explosive Strength

Power or explosive strength: overcoming a small resistance by applying maximum speed.

Strength Endurance

Strength endurance: repeated muscular strength efforts performed over time.

The Force and the Mechanism of Muscle Contraction

Muscles shorten in length during muscle contraction. When muscles remain contracted to hold the skeleton, this... Continue reading "Muscle Strength, Power and Effective Training Methods" »

Musculoskeletal System

The musculoskeletal system is a set of organs that allow you to move the body and maintain its position. It includes the osteoarticular system and other elements that have the ability to produce movement, such as the muscular system.

Parts of the Osteoarticular System

• Bones: Hard and static parts, consisting of living tissue. Their external shape varies; they may be short, flat, or long. They perform four functions:
  • Sustainability
  • Protection
  • Movement
  • Metabolic
• Joints: Areas of contact between two or more bones. The mobility of the bones depends on the type of link they have. They can be:
  • No movement (synarthrosis)
  • Little mobility (joint plane)
  • One axis of movement (hinge joint)
  • Two axes of movement (condyloid joint)
  • Three axes of

Mechanisms Involved in Learning

Subject Motivation and Activation

Motivation and the level of activation are critical for learning. This involves raising expectations and managing anxiety to reach an optimum level of performance. Previous knowledge transfer is essential, categorized into:

• Proactive and Retroactive
• Positive and Negative

Low motivation often stems from a lack of perceived competence or understanding of the task.

Task Components: Perception, Decision, and Execution

• Perceptual Aspects: Managing the number and nature of environmental stimuli (e.g., tennis).
• Decision Making: Influenced by the number of situations, time constraints, uncertainty, and risk levels.
• Execution: Involves segmental differentiation, accuracy requirements, and the

What is Fitness Assessment?

Fitness assessment is a crucial part of sports preparation, used to estimate an individual's fitness level. Its primary value lies in diagnosing potential areas for improvement and guiding the adjustment of the ongoing training process.

How to Evaluate Fitness?

Evaluation can be done subjectively, by considering how you feel and listening to your body. However, to achieve more objective and effective results, measurement through standardized tests is essential. There are primarily two types of tests: those that measure general physical fitness and those designed to assess specific sports performance. Key qualities of effective tests include their yield (practicality), validity (accuracy), objectivity (unbiasedness),...

Anatomy of the Innominate Bone

The innominate bone (commonly known as the hip bone) is a flat bone that falls into the irregular bone category because it features spines, ridges, recesses, cavities, and holes. It consists of three primitive bones:

• Ilium
• Ischium
• Pubis

The Posterior Border and Iliac Crest

Taking the area located behind the ischial tuberosity and down the bone as a starting point, we continue upward to find the lesser sciatic notch, which ends in a sharp projection: the ischial spine. This spine marks the beginning of the greater sciatic notch, which is completed by another acute ledge: the posterior inferior iliac spine. These two projections are located in the ilioischial area.

Following upward, there is a small depression called the... Continue reading "Innominate Bone Anatomy: Structure and Landmarks" »

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... Continue reading "Master Volleyball Rules and Essential Techniques" »

The Importance of Warming Up

Warming up is the set of general activities performed in an effort to prepare the body for higher-than-normal intensity, allowing athletes to reach peak performance.

Objectives of Warming Up

• Improving the performance of the activity that we perform.
• Avoiding injury.

Effects on the Body

Warming up increases corporal capacity. It improves muscle temperature and elasticity, increases the respiratory rate, and raises the heart rate. This increases blood flow to the muscles, ensuring a steady supply of nutrients and oxygen.

Phases of a Warm-Up

1. Activation: Cardiorespiratory movements performed to increase body temperature.
2. Joint Mobilizations: Exercises targeting different joints.
3. Stretching: Stretching the major muscles to avoid
