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" »

Locomotor System

Bones

The skeletal system consists of 200 bones.

• Long Bones: Femur, ulna, radius
• Short Bones: Vertebrae, phalanges
• Flat Bones: Shoulder blade, skull bones, pelvis
• Irregular Bones: Facial bones

Composition of Bones

Mineralized connective tissue

• Cells (2%):
  • Osteocytes: Mature cells
  • Osteoclasts: Destroy tissue
  • Osteoblasts: Create tissue
• Fibers (95%): Tropocollagen
• Fundamental Substance (3%): H₂O

Structure of Bones

• Compact Bone Tissue: In diaphysis (long bones) and flat outer layers
  • Osteons: Small vessels that make up the bone
  • Yellow Marrow: Consisting of fat, feeds the cells

Functions of Bones

• Support the body
• Protect vital organs
• Facilitate movement with joints and muscles
• Store minerals
• Manufacture red blood cells

Joints

• Synarthrosis: Fixed, no movement,

American Perspectives on Motor Development

Studies related to the perceptual-motor area in the United States have been conducted by authors from diverse backgrounds. This section examines the contributions of H. Williams, B.J. Cratty, and David L. Gallahue.

1. H. Williams: The Concept of Perceptual-Motor Development

Previously, the focus on motor development referred to changes and refinements in human motor behaviors. Williams shifted this focus toward improvements in perceptual-motor behaviors, which are categorized into four areas:

• Gross Motor Skills: Mobilizing the body in a coordinated way, such as jumping, running, throwing, hitting, and receiving.
• Fine Motor Skills: Related to the control of small objects using hands, fingers, and eyes (oculo-

Physical Training Methods

Reaction and Speed Training

• Reaction to Different Stimuli

  Consists of moving out as fast as possible from different positions and distances. The shorter the travel distance, the better the reaction rate.

• Multihop Training

  Improves movement speed through small, high-speed jumps.

• Training Method Working with Loads

  Involves traveling a distance while overcoming opposition or resistance that overloads us, thereby improving travel speed.

• Racing Games

  These do not help in improving movement speed; they are known as competitive matches.

Improving Movement Coordination

Improves the performance of various sports techniques.

Athletics Disciplines

Practice Locations

Athletics can be practiced in different places:

• An outdoor stadium
• An indoor
