¿QUÉ ES LA RESISTENCIA? (CAPACIDADES FÍSICAS)( EDUCACIÓN FÍSICA)
Understanding Physical Endurance
Definition of Resistance
- Resistance is defined as the psychophysical capacity of a person to maintain physical effort without decreasing performance. It refers to the ability to sustain effective effort for as long as possible.
Importance of Resistance in Physical Conditioning
- Resistance is a complex capacity crucial for improving physical conditioning, significantly enhanced through training. It is categorized into aerobic and anaerobic resistance.
Aerobic vs. Anaerobic Resistance
Aerobic Resistance
- Aerobic resistance allows the body to maintain high-intensity exercise over extended periods, essential for sports performance by ensuring adequate oxygen and blood supply.
- Classified into short (2-8 minutes) and long (over 30 minutes), it supports respiratory function by continuously transporting oxygen from the lungs to the cardiovascular system.
Anaerobic Resistance
- Anaerobic resistance enables high-intensity efforts with minimal oxygen, closely linked to muscle fatigue, utilizing immediate energy sources like glucose or creatine phosphate.
Types of Anaerobic Resistance
Anaerobic Galáctica
- This type involves executing maximum intensity movements for short bursts (around 5 seconds), relying on ATP as an energy source at full intensity.
Anaerobic Láctica
- Involves high-intensity actions sustained over longer durations (20-45 seconds), where glycogen becomes the primary energy source after ATP depletes within 20 seconds.
Benefits of Training Endurance
- Enhances heart rate efficiency, allowing more blood expulsion per contraction while strengthening heart walls and increasing chamber sizes.
- Reduces resting heart rate, enabling more efficient blood pumping with less effort; increases capillary and alveoli count improves oxygen exchange.
Overall Health Improvements
- Boosts respiratory system efficiency by enhancing lung capacity; optimizes waste elimination via detoxification organs like liver and kidneys.
