Margaret is going to run her first-ever marathon on her 60th birthday. She started training for it few months ago, following a 16-week program for first-time runners. The program recommends training within the "aerobic training" zone. The recommended target rate for "aerobic training" falls between 70%and 80% of maximal heart rate. As the training progresses, the resting heart rate is expected to go down, and the "reserve" between resting and training heart rate and will allow for longer or faster runs. Margaret owns a cardiac monitor that continuously shows her current heart rate as she runs. What is the range of the pulse she should be aiming for during her training?Training heart rate is a range; please enter two numbers, the lower and upper range values, respectively. Separate the lower and upper range values, in that order, by a comma. View Available Hint(s)View Available Hint(s)Hint 1. Calculating maximal heart rateMaximal heart rate = 220 – ageHint 2. Heart rate zones for trainingIntensity rangeWhat it doesTarget heart rateModerateImproves the heart’s ability to pump blood andthe muscles’ ability to utilize oxygen. This range isappropriate for overall health maintenance butdoes not increase fitness.50% - 70%Aerobic trainingIncreases cardio-respiratory capacity. Increasesthe ability of the muscles to use available oxygen. Most effective for increasing cardiovascular fitness.70% - 80%Anaerobic trainingTraining in this zone increases the lactatethreshold, which improves performance.80% - 90%Maximum "red line" trainingPossible only for very short periods of time. Training in this zone increases fast-twitch musclefibers and speed.90% - maxbpmSubmitPrevious AnswersRequest AnswerSubmitted AnswersANSWER 1: 80,112 bpmANSWER 2: 128,144 bpmIncorrect; Try Again; 4 attempts remainingPart B - Measuring Your Own PulseJohn, who is training with Margaret, has no heart monitor, and he cannot afford to buy one. He has to rely on his watch and his ability to measure his own pulse on his wrist. John is 27 years old and wants to train at the higher end of aerobic range, between 75% and 85% of his maximal heart rate. On his last run, John counted 30 heart beats in 15 seconds. Is he training within his target range?View Available Hint(s)John, who is training with Margaret, has no heart monitor, and he cannot afford to buy one.

Is he training within his target range?Yes, he is training within his target range. No, he needs to run faster to increase his heart rate. No, he ran too fast, past his target range and too much into the anaerobic range.
