📊The formula of 220 minus age for maximum heart rate is not based on scientific evidence and is an arbitrary number.
📉The accuracy of the 220 minus age formula is affected by factors such as physical activity, overall health, and loss of elasticity in the circulatory system.
🔄As individuals age, the formula becomes increasingly inaccurate and unreliable for determining maximum heart rate.
❗️Using threshold heart rate derived from a hard sustained run is a more accurate method for determining training zones and target heart rates.
🏃♀️Regular exercise and physical activity can have a positive impact on heart health and the accuracy of heart rate measurements.
