Understanding and Training Endurance

Resistance is the ability to sustain effort, with varying intensity, over a prolonged period. To classify resistance, we consider two key concepts: muscle participation and energy production.

Muscle participation refers to the amount of muscle groups involved in the activity:

• General resistance: Involves most muscle groups in activities or exercises.
• Specific resistance: Involves specific muscle groups, such as arms, legs, or abs.

Energy production refers to the system by which the body obtains the necessary oxygen to produce energy in the muscle:

• Aerobic endurance: Occurs when sufficient oxygen reaches the muscle to produce energy.
• Anaerobic resistance: Occurs when the oxygen supply is insufficient for the intensity

Physical Conditioning

Physical Condition: The ability to perform daily tasks with vigor and effectiveness, delaying fatigue and preventing injury. This involves maximizing efficiency and minimizing energy expenditure. Basic physical conditions are: resistance, strength, speed, and flexibility.

Principles of Training

Principle of Adaptation

The human body can withstand physical activity and adjust to its practice. After running, the body undergoes wear that causes a momentary decrease in physical level. Later, the body recovers and reaches a new level, higher than the previous one (overcompensation).

Principle of Progression

The human body is capable of increasing efforts progressively. To achieve an increase in physical fitness, exercise must be... Continue reading "Baseball Fundamentals and Training Principles" »

Assessing the Need for Mobilization

In many cases, victims do not fully recover from initial first aid. It's often appropriate to consult professional services to confirm the best course of action. When deciding whether to evacuate to a hospital emergency room, determine if it's appropriate to wait for emergency services or if it's preferable to move the person to a safe location.

Improper handling and transport can aggravate injuries, especially fractures that could become open fractures if not handled correctly.

The recommended action sequence is:

1. Perform an emergency assessment and take appropriate actions on site.
2. Stabilize vital functions.
3. Decide whether to wait for emergency services or transfer the person to a hospital.
4. Place the person in

Basic Physical Features

Basic physical features determine the capacity or general fitness of an individual, and training allows room for improvement.

Basic Qualities

Basic qualities are indispensable and participate in most physical activities. Within these, we find strength, speed, endurance, and flexibility.

Complementary Qualities

Complementary qualities must be present in any physical activity, but they are not as indispensable.

Derivative Qualities

Derivative qualities are produced as a result of the conjunction of various basic and complementary physical qualities. Examples include power and agility.

What is Strength?

Strength is the ability to generate muscle tension. It is the ability that is acquired the fastest but also the most easily lost.... Continue reading "Understanding Physical Fitness: Strength, Speed, and Endurance" »

Forensic Wound Analysis: Differentiating Cause of Death

5. Wound Severity and Characteristics: The severity of a wound, the presence of subcutaneous fat between wound edges, and blood clots intimately attached to mesh fabrics can provide crucial information. The presence or absence of vital reaction (bleeding) is interpreted to determine if the wound occurred before or after death. This aids in the diagnosis of origin: suicide, homicide, or accidental.

Medical evidence includes puncture wounds, cutting wounds, and piercing wounds. The location of wounds, their number, and characteristics are important, as are any corresponding marks on the victim's clothing.

Key Factors in Wound Interpretation

1. Wound Location

Wound location provides probability... Continue reading "Forensic Analysis: Interpreting Wound Characteristics in Violent Deaths" »

Floorball Penalties, Expulsions, and Goals

Penalty Shot

A penalty shot is awarded due to an infringement. Play restarts with the ball placed at the central point. All players, except the player taking the penalty and the goalkeeper, must remain in the substitution zone until the play is complete. The goalkeeper must be on the goal line when the penalty shot is taken. The player taking the penalty is positioned on the center line and can play the ball an unlimited number of times, but the ball must continuously move forward.

Situations Leading to a Penalty Shot

A penalty shot is awarded when, in a clear goal-scoring opportunity, a player from the defending team commits an infraction to prevent the attack from progressing.

Fines and Expulsions

Player... Continue reading "Understanding Floorball Penalties, Expulsions, and Goals" »

Technical Activities

The technical term comes from the Greek technné, which meant art, craft, method, and technique. We can define it as the ability to modify the environment to one's advantage, which consists of the possession of effective ways to proceed, the possibility of creating, and using tools that construct the action helpers. Animals can build things that seem to be a product of the technique, but in reality, it is limited to fixed patterns of behavior, so they do not have the capacity to refine their constructions, nor to invent and fabricate other devices that work best. Primates only minimally approach the human ability to imagine, build, and use effective tools in the solution of the problems they encounter.
