Physical Fitness: Warm-up, Muscle Contraction, and Resistance
The Importance of Warming Up
What is Warming Up and Why is it Necessary?
Warming up is the activity performed before any type of sports activity to prepare the body.
How is the Warm-up Performed?
- Soft activities.
- Global use of the whole body.
- Progressive intensity (from low to high).
- Structured execution of exercises.
- Continuous execution (i.e., without major breaks).
Types of Warm-up
- General: Performed before any physical activity.
- Specific: Tailored to a determined sport or activity.
Effects of Warming Up
- Improves
Statistical Test Interpretation and SPSS Decision Rules
Statistical Significance: The Main Rule
The decision rule for hypothesis testing is based on the p-value:
- p < 0.05: Significant → Reject H0 (Null Hypothesis)
- p ≥ 0.05: Not significant → Fail to reject H0
Choosing the Appropriate Test:
- 1 group vs known value → One-Sample T-Test
- 2 groups (different people) → Independent Samples T-Test
- 2 groups (same people before/after) → Paired Samples T-Test
- 3+ groups → ANOVA (+ Tukey Post-Hoc if significant)
- Numeric ↔ Numeric relationship → Correlation
- Predict

Influenza Virus: Symptoms, Spread, and Prevention
Influenza: Causes and Terminology
The flu, or influenza, is an infectious disease affecting birds and mammals, caused by an RNA virus belonging to the Orthomyxoviridae family. The word “flu” originates from the French grippe (from Swiss-German groupie, meaning ‘curl’), while “influenza” comes from Italian.

Key Events and Conflicts of the Cold War Era
The Cold War Period
The Cold War was a long period of tension between the democracies of the Western World and the communist countries of Eastern Europe. The West was led by the United States, and Eastern Europe was led by the Soviet Union. These two countries became known as superpowers. Although the two superpowers never officially declared war on each other, they fought indirectly in proxy wars, the arms race, and the space race.
The Iron Curtain and Germany

Education
Simón Bolívar participated intensely in the intellectual world of his epoch, thanks to favorable circumstances. Being part of the Creole aristocracy allowed him, from childhood, the opportunity to access classical culture and attend scenarios where important historical facts of Bolívar’s time developed. His school performance was not very bright as a student at the Public School, an institution run by the Caracas City Council that functioned poorly due to a lack of organization and resources.

🧩 4.1 Security Administration on Computing Resources
🔹 Secure Baselines
Define secure configurations (disable unused ports, enforce strong passwords, patch systems).
Deploy via configuration tools (Group Policy, Ansible, SCCM).
Maintain through regular audits and updates.
🔹 System Hardening
| Target | Key Techniques |
|---|---|
| Workstations/Servers | Disable Telnet/FTP; patch OS/apps; use AV + firewall; limit admin privileges. |
| Mobile Devices | Use MDM, enforce encryption, PIN/biometrics, remote wipe, containerization. |

Understanding Computers: Functions, Features, and Generations
Definition of Computer:
A computer is an electronic device that processes input data according to a set of instructions (programs), stores it, and produces meaningful output as information. It performs four basic operations: Input, Processing, Storage, and Output.
It is a data processing machine that can perform arithmetic and logical operations at extremely high speed and accuracy.
It is used in every field today due to its efficiency, reliability, versatility, and automation capabilities.
