Final answer:
Option A. Physical fitness helps reduce the risk of chronic diseases, overtraining can lead to muscle injuries for which RICE is a treatment, sleep apnea causes sleep deprivation, and the target heart rate zone for exercise is based on an individual's RHR and age.
Step-by-step explanation:
The relationship between the key terms in each of the following pairs can be explained as follows:
- Physical fitness and chronic disease: Engaging in regular exercise increases physical fitness, thereby improving the efficiency and strength of the body's systems and organs. This enhancement in physical fitness is associated with a decreased risk of developing chronic diseases such as cardiovascular disease, diabetes, and obesity.
- Overtraining and RICE (Rest, Ice, Compression, and Elevation): Overtraining can lead to muscle injuries and the RICE method is a common treatment for such injuries. It helps in reducing swelling, pain, and promoting healing.
- Sleep apnea and sleep deprivation: Sleep apnea is a disorder that causes pauses in breathing during sleep, leading to sleep deprivation. Sleep deprivation can exacerbate the symptoms of sleep apnea and impact overall health negatively.
- RHR (Resting Heart Rate) and target heart rate zone: RHR is the number of heartbeats per minute while at rest and can be an indicator of cardiovascular fitness. The target heart rate zone is a range that is considered optimal for cardiovascular exercise to reap health benefits without overexerting, which is personalized based on RHR and age.
