Answer:
A 17 year old with a resting heart rate of 62 bpm has a maximum hearth rate of 203 bpm, a hearth rate reserve of 141 bpm and target hearth rate between 161 and 182 bpm
Explanation:
Target heart rate is a measure used to calculate the range of heart rate that should be maintained during intense exercise.
Knowing a person's age and resting heart rate (RHR), a target heart rate calculation can be made from the maximum heart rate (MHR) and the hearth rate reserve (HRR)
Data:
- Age: 17 years old
- RHR: 68 bpm
The maximum heart rate is calculated by subtracting age from a constant value of 220, so:
- MHR = 220 - age
- MHR = 220 - 17
- MHR = 203 bpm
HRR is calculated by subtracting the resting heart rate (RHR) from the MHR value:
- HRR = MHR - RHR
- HRR = 203 - 62
- HRR = 141 bpm
THR is obtained by multiplying the HRR by 0.7 and 0.85, to obtain the range of heart rate in which the exercise can be performed.
- THR lower limit = (HRR x 0.7) + RHR Lower THR = (141 x 0.7) + 62 = 160.7 ≈ 161 bpm
- THR top limit = (HRR x 0.85) + RHR THR top = (141 x 0.85) + 62 = 181,85 ≈ 182 bpm
For the 17-year-old, the ideal target heart rate for an intense exercise is between the values of 161 and 182 bpm.
Answer: The correct option is IRON DEFICIENCY ANAEMIA
Explanation:
Anaemia is a condition that arises when there is not enough haemoglobin available to carry sufficient oxygen from the lungs to supply the needs of the tissues. It occurs when the rate of production of mature cells entering the blood from the reb bone marrow does not keep pace with the rate of haemolysis.. Anaemia can be classified based on:
--> impaired erythrocyte production example, Iron deficiency anaemia. Or
--> increased erythrocyte loss example, haemolytic anaemia.
IRON DEFICIENCY ANAEMIA occurs when the amount of iron nutrient needed in the body system for the production of haemoglobin is decreased. The symptoms includes
- impaired work performance,
- general fatigue,
-pale skin,
- depressed immune function,
- impaired cognitive and nerve function, and impaired memory.
