Answer:
Maybe if his fists are clutched he is holding a part of his body in pain and maybe if he is making tense faces
Explanation:
Poor flexibility can make body movements, such as kneeling and bending over, far more difficult. Accomplishing activists like cleaning the house can require bending over and kneeling, so when poor flexibility negatively impacts these activities, it makes larger tasks more difficult.
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.
