B1 Fitness and health
  1. Blood Pressure
    1. It is measured in millimetres of mercury.
      1. Systolic pressure - maximum pressure the heart produces.
        1. Diastolic pressure - blood presure between heart beats
          1. Increased by stress, alcohol, smoking, being overweight
            1. Decreased by regular exercise, balanced diet
              1. Hight blood pressure can cause blood vessels to burst.
                1. Low blood pressure can lead to dizziness/fainting
                2. Fitness and health
                  1. Fitness - ability to do physical activity
                    1. Health - free from diseases
                      1. Level of fitness measured by cardiovascular efficiency
                        1. Fitness also measured by; strength, flexibility, stamina, agility, speed
                          1. Ways of meausring fitness should be evaluated to check effectiveness in particular situations
                          2. Smoking
                            1. Smoking can increase blood pressure
                              1. Carbon Monoxide is in cigarette smoke
                                1. Nicotine in cigarette smoke directly increases heart rate
                                  1. Carbon monoxide decreases the oxygen-carring capacity of blood
                                  2. Diet and heart disease
                                    1. Heart disease caused by bad blood flow to the heart
                                      1. Risk of heart disease increase by having a lot of fat which builds up in arteries
                                        1. The narrowing of arteries caused bt plaqus in the coronart arteries can reduce blood flow to the heart
