Skills are abilities that athletes acquire through practice to perform techniques. Techniques are the basic movements in a sport that are combined into patterns. There are three stages of motor skill acquisition - cognitive, associative, and autonomous. In the cognitive stage, athletes learn the components of a skill. In the associative stage, they link components into a smooth action. In the autonomous stage, the skill becomes automatic. Tactics involve decision making in competition situations based on strategy. Tactical training methods include acquiring tactical knowledge, consolidating knowledge, and developing creative abilities.
Heart rate
Your heart rate is the number of times your heart beats in one minute. It changes with your activity level and tells how hard your heart is working. Your resting heart rate is measured in the morning before getting up, while your maximum is calculated using your age. To measure your heart rate, count beats in your neck for 15 seconds and multiply by 4. Your working heart rate is a percentage of your maximum based on the type of exercise and results desired, such as 55-70% for aerobic or 70-80% for cardio.
Personality & sports
The document discusses personality in sports and exercise psychology. It covers major approaches to understanding personality like the psychodynamic, trait, situation, and interactional approaches.

1.2.2 Lesson 1 - immediate effects on the cv system
The cardiovascular system consists of the heart, blood vessels, and blood. The heart pumps blood through three types of blood vessels - arteries, veins, and capillaries. Exercise has immediate effects on the cardiovascular system such as increased heart rate and blood pressure. The heart contains four chambers and blood pressure can be measured to track systolic and diastolic pressure. Maintaining a healthy cardiovascular system requires regular exercise and avoiding unhealthy behaviors.
Immediate effects-of-exercise
Regular exercise provides both immediate and long-term benefits to the body. In the short-term, the body experiences increased heart rate and breathing to supply oxygen to working muscles, elevated body temperature through the generation of heat, sweating to regulate temperature, and muscle fatigue from lactic acid buildup. Over time with training, the cardiovascular system becomes more efficient as the heart can deliver the same blood volume with fewer beats, the recovery rate is quicker, and the resting heart rate is lower.

Ped488 dyslipidemia s 11
Dyslipidemia refers to abnormal blood lipid or lipoprotein levels and is linked to increased risk of cardiovascular disease. It involves high levels of triglycerides and/or cholesterol, which circulate in the bloodstream within lipoprotein particles. Lifestyle factors like diet, physical activity, smoking, and alcohol can influence lipid levels. Regular aerobic exercise of moderate intensity for 30-60 minutes per day at least 5 days per week is an effective way to improve lipoprotein profiles through increased calorie expenditure and weight control, particularly by raising HDL levels and lowering triglycerides.
1.2.3 Lesson 1 - The respiratory system
1) The respiratory system works by inhaling air through the nose and mouth into the lungs. During inhalation, the diaphragm and intercostal muscles contract to expand the lungs and decrease pressure, allowing air to rush in.
2) Gas exchange occurs in the alveoli where oxygen passes into the blood and carbon dioxide passes out of the blood. The air then exits during exhalation through the same process in reverse.
3) Tidal volume and vital capacity can be measured using a spirometer or peak flow meter. Tidal volume is the amount of air inhaled and exhaled during normal breathing, while vital capacity is the maximum amount of air that can be inhaled and

In contrast, an unhealthy lifestyle negatively impacts the cardiovascular system. Students are directed to complete notes, tasks, and reviews in preparation for an upcoming test on cardiovascular health.
Long-term Effects of Exercise on High-density Lipoprotein Cholesterol Levels
Long-term exercise can increase HDL cholesterol levels and reduce cardiovascular disease risk. Several studies showed that resistance training alone increased HDL levels up to 8% in men and 1% in women. Adding aerobic training to resistance training led to greater increases in HDL of up to 15% for men and decreases of up to 8% for women. Both longer duration aerobic sessions (>1 hour) and higher intensity interval training produced greater increases in HDL levels compared to shorter or lower intensity continuous exercise. Overall, higher volume and intensity exercise programs over months to years resulted in the greatest raises in HDL cholesterol.
Sport unit 2 p4
Regular exercise leads to several long-term effects on the cardiovascular and respiratory systems. The heart muscle thickens and increases in size, raising stroke volume and cardiac output. This allows the heart to pump more blood with each beat and a lower resting heart rate. Capilliarization improves oxygen delivery to working muscles. Blood volume and aerobic fitness increase while resting blood pressure and recovery time decrease. The muscular system also adapts through increased myoglobin and mitochondria stores, glycogen and fat storage, tendon and muscle strength, and tolerance to lactic acid buildup.

The respiratory system consists of the nose, mouth, larynx, trachea, bronchi, bronchioles and lungs. The purpose of the respiratory system is to bring air into close contact with the blood so that oxygen can be absorbed and carbon dioxide can be removed. In the alveoli, gas exchange occurs where oxygen from the inhaled air diffuses into the blood and carbon dioxide from the blood diffuses out and is exhaled.
Effects on cardiovascular system
Regular exercise has long-term benefits for the cardiovascular system. It decreases resting heart rate and improves heart recovery rate as the heart becomes stronger and more efficient. Additional benefits include increased stroke volume, meaning the heart can pump more blood with each beat, as well as reduced blood pressure. Overall, regular exercise leads to a more efficient cardiovascular system that is under less stress.
Cardiovascular response to exercise
The document describes an experiment that measured and compared the vital signs of athletic and non-athletic subjects during different exercise regimens involving treadmill use. Sixteen students monitored subjects' blood pressure, pulse rate, and other vital signs as the subjects performed various warm-up, exercise, and cool-down routines. The results were recorded and showed changes in vital signs over time and between athletic and non-athletic groups. Potential sources of error in the experiment are also outlined.
