Item 3: Resistance

Resistance is the ability that allows us to maintain physical effort for a prolonged duration and recover more quickly afterward.

In the Muscular System:

• Type of muscle fiber
• Energy deposits to obtain ATP
• Ability to remove lactic acid that accumulates after anaerobic work, preventing fatigue

In the Nervous System:

• Coordination of different muscles to execute movement

In the Circulatory System:

• Quantity of blood flow
• Capacity of the body to transport oxygen and energetic substances

In the Respiratory System:

• Ability to deliver oxygen to the body
• Oxygen exchange in the alveoli of the lungs and muscle cells

Classification:

Based on energy pathways that provide energy to the muscles, and characteristics of volume and intensity.

Analysis and prevention of damage caused by work.

Prevent workers from suffering any injury while on the job. This requires participation from all stakeholders: workers, technicians, and employers. Prevention organizations (e.g., mutual insurance companies, INSHT) and relevant legislation (local, regional, national, European) also play a crucial role.

Understanding Workplace Damage

Direct Damage: Workplace Accidents

Legal Definition of Workplace Accident

Any injury workers suffer in connection with or as a consequence of the work performed for others. Also considered accidents:

• In itinere (on the way to/from work)
• While performing trade union duties
• During professional performance in rescue acts
• When suffering an occupational disease not officially

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.

Understanding Kyphosis

Kyphosis (from Greek κύφος, "convex," and the suffix -osis, indicating "state" or "process") refers to a condition where the spine exhibits an excessive outward curvature, often leading to a loss of its natural inward curves in affected segments. This condition causes a visible tilt in the back, often perceived as poor posture.

The symptoms of kyphosis that may or may not occur, depending on the type and extent of the deformity, include back pain, fatigue, a visibly curved back, shortness of breath, discomfort, and even death (in extremely severe and rare cases).

Types of Kyphosis

There are many types of kyphosis, including:

• Postural Kyphosis

  This is the most common type, usually attributed to poor posture. It represents

Changes in the Musculoskeletal System During Aging

During aging, there is a loss of bone mass, decreased muscle strength, osteoarticular changes, an increase in reaction time, and decreased speed of movement.

Gait Alterations

One of the consequences of changes that occur in the musculoskeletal system is an alteration in the structure of harmonious gait and balance.

Characteristics of Movement

• Slow movements.
• Slowing of trunk rotation.
• Reduced arm swing.
• Absence of heel lift.
• Minimal toe lift.
• Reduced single-leg stance.

Care for Nurses

• Re-educate balance.
• Encourage the use of assistive devices.
• Reduce environmental barriers.
• Recommend exercises to delay deterioration.

Osteoarticular Problems

Older adults may experience various joint diseases. The risk of disability... Continue reading "Musculoskeletal Changes, Falls, and Rehabilitation in Aging" »

Muscle tension results from the contraction of muscle fibers. In the muscular system:

• Muscle fiber types: fast or slow, length, and thickness.
• Volume of fibers (muscle hypertrophy).
• Types of muscle contraction: concentric, isometric, and isotonic.

In the nervous system:

• Coordination of different muscles for movement: agonists, antagonists, and fixers.

Other factors:

• Muscle temperature, which can increase with a good warm-up.
• Training, form, or motivation.

Sorting: Force = Mass x Acceleration

Maximum Force:

The capacity to create maximum tension during muscle contraction. It is related to muscle mass or load.

Maximum Acceleration:

Minimal or no load, for example, when a weightlifter lifts weights in competition.

Explosive Strength:

The ability to overcome... Continue reading "Understanding Muscle Strength, Speed, and Flexibility" »

Passing and Cutting

Date: 25/11/08

Objectives:

1. To gain an advantage towards the basket by a player without the ball.
2. To pass the ball to a teammate who gains an advantage.

Requirements:

1. The player with the ball facing the basket.
2. Change of direction and/or speed of the player without the ball (the player who just received the pass).
3. Awareness of different gameplay options.

Features:

1. Context analysis: distance to the basket, free space, and run of the player without the ball.
2. The characteristics of the players involved in the action (tall, short).
3. Context of the game (e.g., 24-second clock at the end of a period).

Blocking (Offense)

Date: 04/12/08

Objectives:

1. Retrieving the ball after a missed shot.
2. Facilitating an advantage for oneself or a teammate.
3. Hindering

Developing Children's Dressing Skills

Understanding Clothing Habits Development

Children's habits related to clothing can be distinguished into three main areas:

• Dressing and Undressing: Fostering autonomy in self-care.
• General Appearance: Emphasizing cleanliness and appropriate clothing choices.
• Clothing Care: Promoting cleanliness, order, and maintenance.

Initially, the adult is responsible for these tasks. As a child grows, they begin to participate actively in these processes.

Key Considerations for Skill Development

Developing clothing habits is an activity that significantly encourages affective development, as it promotes communication and interaction. To foster a child's interest and motivation, consider the following strategies:

• Clear Explanations:

Sports Training Planning: Essential Considerations

Effective sports training planning is crucial for athlete development and performance. It requires careful consideration of several key factors:

• Athlete Characteristics and Goals: Understanding the individual athlete's unique traits and their specific performance objectives.
• Available Resources: Assessing the equipment, facilities, and support personnel at hand.
• Competition Calendar: Aligning training phases with important competitions and events.
• Factors Affecting Performance: Identifying all potential influences on an athlete's performance throughout the periodized planning cycle.

Levels of Sports Training Planning

Training planning is structured across different time horizons to ensure progressive... Continue reading "Strategic Sports Training: Planning for Peak Athlete Performance" »

Fundamental Principles of Training

• Multilateralism: Training should comprehensively develop both the body and fundamental physical qualities.
• Continuity: Physical effort should be sustained without interruptions to maximize benefits.
• Gradual Growth of Effort: Training intensity should progress from low to high, increasing as the individual adapts.
• Overload: Adaptation occurs when stimuli exceed the body's current capacity, prompting improvement.
• Transfer: Physical exercises should be chosen with a specific objective, ensuring they contribute to desired performance outcomes.
• Specificity: Training must be tailored to the athlete's particular sport or specialty.
• Voluntary Stimulation: Genuine improvement stems from voluntary and conscious effort during
