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),...

The Essence of Human Movement

Understanding Movement

The term Movement originates from the Latin movere. According to the Royal Spanish Academy Dictionary (DRAE), it refers to the act of a body leaving its occupied place or space to proceed and occupy another, or the translation of a body in space.

It's important to note that when the DRAE refers to "body" in the context of movement, it does not exclusively refer to the human body, except in specific cases like body movements in fencing. In other dictionary senses, the human body is considered a moving body just like any other physical body. Therefore, when discussing human body motion, the term "movement" should ideally be accompanied by a qualifying adjective like "human" to specify its context....

Standardization

Standardization is defined as a set of technical requirements that specify, unify, and simplify aspects of industrial processes. This standardization affects:

• a) The form, composition (wt% specifies the components), dimensions, and physical and chemical properties of materials.
• b) Terminology and symbols (standard symbols must be used for universal interpretation).
• c) Calculation methods, materials testing, measurement, and usage.

Certification is the action carried out by a recognized, independent organization, testifying that a company, product, process, service, or person meets the requirements defined in standards.

A standard is a document containing technical agreements made between manufacturers, users, and technical groups... Continue reading "Engineering Standardization, Tolerances, and ISO System Fits" »

The Musculoskeletal System: Structure and Function

The musculoskeletal system is essential for human movement and locomotion. It is composed of three interconnected systems:

The Skeleton (Bones)

The skeleton is the union of all bones, consisting of 206 bones joined to each other, with the exception of the hyoid bone. Bones provide structure and protection.

Characteristics of Bones

• Stiffness
• Flexibility
• Elasticity: Bones in children are generally more elastic, while adult bones are more rigid.
• Resistance

Types and Functions of Bones

Bones are classified by shape: long, flat, and short. Their primary functions include:

• They support and protect vital body structures.
• They produce red blood cells (hematopoiesis).
• They store essential minerals (e.g., calcium)

Developing Motor Skills

Rolling, Crawling, and Creeping:

• Spins about its longitudinal axis is one more automated motor pattern at 6 months.
• Creeping usually occurs around 5 months.
• From 6 to 8 months, infants are capable of creeping effectively.
• Crawling starts around 8 to 10 months.

Walking:

• The first steps are a constant search for equilibrium and stability.
• Standing upright at 12 months and starting to walk around 14/15 months; there is great variability in their first steps from 9 to 18 months, depending on development.

Running:

• The first actions similar to running appear as an uncontrolled gait around 18/20 months.
• By age 5, children can run with some ease.

Jumping:

• After an acceptable performance level in gait, around age 4, jumping becomes possible

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

Developing Travel Speed Components

This quality depends on the balance of all components: frequency, amplitude, speed endurance, and technique, as well as an adequate speed of execution, which leads to good acceleration determined by contractile speed. Considering these components:

Stride Length

Improved through exercises that work driving ability, such as multihops without light burden or long jumps. Similarly, exercises to improve joint range using downhill slopes with wide steps, progressions extending the stride, and flexibility work are beneficial.

Frequency of Movements

Closely tied to stride length, a balance must be found. Develop this through segmental movements at maximum speed using multiple repetitions. This involves techniques like... Continue reading "Improving Athletic Speed: Components and Training Methods" »

Handball Fundamentals: Mastering Key Techniques

It is impossible to play handball without mastering the pass.

Passing Techniques

Types of Passes

• Front Pass: Executed by passing the ball from head height, with arms extended forward.
• Lateral Pass: The ball is passed from chest level, moving from the center outwards.
• Picado (Bounce) Pass: Thrown towards the ground so the ball bounces and reaches a teammate.
• Dejada (Drop) Pass: Involves placing the ball in the palm of the hand and passing it to a teammate.
• Suspension Pass: Executed while airborne, typically just before a jump shot.

Throwing (Lanzamiento) Techniques

There are several types of throws in handball:

Types of Throws

• Support Throw: This throw is executed with one or both feet on the ground.
• Suspension

Physical Activity and Training

Training is the set of practices aimed at regulating and improving performance over time.

Training Objectives

• Motivation
• Positive thinking

Sports Training

• Fitness training
• Technical and tactical training

Training Maintenance

Maintaining fitness or engaging in physical activity.

Fitness Training

Motor Skills

Allow individuals to perform movements with full efficiency.

Loading or Work

Training exercises are based on volume and intensity.

Recovery or Rest

There are two types: complete and incomplete, passive and active.

Fatigue

A state transition created in the body due to effort.

Performance

Act Selye

A stimulus in the body produces a stress reaction, generating a reaction that increases performance.

Schultz Law

Each person has an initial... Continue reading "Physical Activity, Training, and Fitness: A Comprehensive Overview" »

Prions and Disease Transmission

Prions are viral proteins that cause diseases. Direct transmission is not common, but the disease can appear several years after exposure to surgical instruments, needles, or other objects used on infected corpses. Therefore, it is crucial to destroy these instruments. STH or GH, this hormone found in the pituitary of dead bodies, requires disinfection of equipment to prevent contamination of the conjunctiva and injured nerve or blood tissue.

Tuberculosis Transmission and Disinfection

Tuberculosis is transmitted through inhalation. When handling fresh infected lungs, they should be perfused with sliced formalin before using routine disinfectants. This increases the time for disinfestation.
