Hi everyone, I ran an outdoor running session lasting almost 13 minutes, covering 2.32 km away, consuming 143 active calories and 162 total calories. For just over a minute, I shot, bringing my heart to almost 180 beats per minute. After finishing, I performed a 30-minute martial arts session in which I limited myself to making simple technical movements, 3 minutes with a light punching bag exercise and an average of 163 beats per minute, without even sweating. 229 total calories and 179 active calories. How is it possible? Why does Apple Watch calculate so many calories for a much less tiring and stressful activity than a run? I ask again: does Apple Watch calculate the detected parameters of its sensors identically for all activities? I ask to know if the sense of signaling to the device that you are running outside the home or inside is only to record it for your "sports history" and not to obtain different measurements. Thank you all!
