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.

Standard Fish Portions and Cuts

1. Serving Sizes

• Standard Fish Portion: 200 to 300 grams.

2. Major Cuts and Preparations

• Major Parts (Slice): 200–250 grams. This cut typically includes meat, skin, and bones from the cylindrical body section.
• Tranche: A vertical slice cut across the fish, including skin and bone. Approximately 200–250 grams.
• Medallion: A large, thick, skinless, and boneless round cut. Serves 2 or 3 people (50–75 grams per unit).
• Supreme: The loin cut, boneless, served with or without skin. Approximately 150–180 grams.
• Darne (Steak): A thick cross-section cut, often from fish like salmon or bass. Obtained from fillets by boning the center, cutting the tail and the center section. Serves 2 to 4 people (150–180 grams).
• Fillets:

Components of Training

Load

Volume

Volume is the quantitative aspect of training. It involves the sum of all work done in one session. Volume values are usually low, medium, or high. Its main feature is its extension: measured in repetitions, distance, or time. Increasing volume is achieved by one or more of the following:

• Increase of distance, e.g., meters traveled.
• Increase in the number of repetitions performed.
• Increase in the number of exercises included in the program.

Intensity

Intensity is the qualitative aspect and refers to the amount of energy employed at a given moment. High-intensity loads require greater effort and, when applied correctly, allow the organism to reach near-maximum performance and ensure training adaptations. If we fail...

Athlete's Foot: Causes, Symptoms, and Treatments

Athlete's foot is a fungal infection that causes lesions in the folds and the soles of the feet.

Causes of Infection

One cause is wearing shoes or clothing of other people who are affected. In severe cases, cracks occur between the toes. Infection often occurs by walking on the grass of public places. Chronic cases can affect the nails and the whole sole of the foot.

Common Symptoms

Symptoms include itching between the toes, a stronger smell, blistering, and serious skin irritation.

Treatment Options

Treatment involves antifungal drugs in the form of creams and powders. In extreme cases, a doctor may prescribe oral drugs.

The Importance of Relaxation for Health

Relaxation is one of the best means that... Continue reading "Managing Athlete's Foot and Mastering Relaxation" »

1. Mature Bone Structure: Tissue Types

Bone is composed of two tissue types:

• Compact Bone: Strong, dense tissue with a structure similar to ivory.
• Trabecular Bone: A mesh-like bone tissue with intercommunicating spaces.

2. Classification of Bones

• Long Bones: Elongated and slightly wider.
• Short Bones: Small and solid.
• Flat Bones: Thin and of considerable surface area.
• Irregular Bones: Possess complex, irregular shapes.

3. Regions of the Vertebral Column

The column is divided into 5 regions:

• Cervical
• Dorsal (Thoracic)
• Lumbar
• Sacral
• Coccygeal

4. Types of Joints and Basic Characteristics

• Synarthrosis: Immobile, fixed joints.
• Amphiarthrosis: Joints with low mobility, including ligaments, cartilage, and symphysis.
• Synovial: Joints with high mobility.

5. Limitations

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.

Optimizing Respiration & Mastering Relaxation

Understanding Respiratory Mechanics

Respiratory-Movement Relationship

Respiration involves the exchange of oxygen (O2), carbon dioxide (CO2), and nitrogen, enabling the body to generate energy.

Types of Breathing

• Chest Breathing: Involves intercostal muscles or abdominal muscles.
• Diaphragmatic Respiration: Often complements chest breathing for complete respiratory function.

Dynamic Respiratory Phases

The dynamic output includes: Abdominal Inspiration, Thoracic Inspiration, Abdominal Expiration, and Thoracic Expiration.

Tips to Enhance Respiratory Capacity

• Avoid awkward postures.
• Practice deep breathing (e.g., in a park or mountain setting).
• Maintain a calm, steady breathing pace.
• Avoid accelerated breathing.

Pediatric Health Concerns: Eating Habits and Sleep

Disorders of Eating Habits

The first step in addressing alterations to eating habits is to seek out possible organic and psychological causes. The most common disorders include:

• Regurgitation
• Vomiting
• Intolerance and Allergies
• Childhood Obesity
• Childhood Anorexia
• Pica
• Rumination

Regurgitation

This is characteristic of infants and involves expelling a small amount of milk after feeding. It usually disappears with the maturation of the baby's digestive system.

Vomiting

This is the more or less abrupt expulsion of a quantity of food. If your baby is gaining weight, there is no need to worry. To avoid this, ensure the infant does not swallow air when breast or bottle-feeding, and burp them when finished. Continuous... Continue reading "Childhood Eating Disorders and Sleep Patterns" »

Principles of Training

The capabilities we all possess are capable of being improved by training. A training system has to be customized based on the needs and requirements of each individual.

Organic Adaptation

The adaptation mechanisms that training produces in the human body will result from the cause-effect relationship between physical stimuli and the response each of us is capable of giving to these stimuli, as a function of their nature and their genetic characteristics.

Adaptation is the functional and morphological modification that occurs progressively in our body due to the application of training loads or simply due to adaptation to the environment in which we live.

The training principles are the guidelines to be followed for the equipment... Continue reading "Training Principles for Optimal Physical Condition" »
