Heartbeat experiment with LS1

In our recent inquiry, we studied the four Hauora walls of well-being and our heartbeat. The four Hauora walls are Taha Tinana (physical well-being), Taha Hinengaro (mental and emotional well-being), Taha Whanau (social well-being), and Taha Wairua (spiritual well-being). When these walls are compromised, athletes may lose their motivation. We also delved into the topic of our heartbeats. We began by estimating the number of times our hearts beat each day. I estimated 87. Then we moved on to discussing whether a faster or slower heart rate is better, and what our heart rate might indicate about our fitness and health. I suggested that a faster heartbeat is beneficial because it allows the heart to pump blood more efficiently. I imagined my heart saying, “I need to work harder and become fitter, but I’m still healthy.” Later, we paired up and set a 20-second timer. My partner checked my pulse three times, and then I checked hers. My pulse rates were 30, 25, and 35. We multiplied these numbers by three, resulting in 90, 75, and 105. Adding them together gave us 270, and then dividing by three resulted in my resting heart rate of 95. After recording our resting heart rates, we went outside for some exercise. Upon returning, we repeated the process to find our active heart rate. Mine was also 95. Following this, we discussed with our partners why our heart rates might differ from those of athletes. I proposed that athletes enhance their stamina and muscle strength through rigorous training, allowing them to use oxygen more efficiently. In contrast, I wouldn’t be able to endure as much physical training due to the likelihood of getting exhausted quickly. I noted that my resting heart rate used to be 90 when I didn’t engage in any exercise, but now my active heart rate is 95. Have you also observed a similar change? It’s important to remember that the heart’s primary function is to circulate blood and oxygen throughout the body. I really enjoyed this task because I got to feel my pulse.
