Rest Day
You have to Run at least one time to start using the Rest Day Button.
Rate of Oxygen Uptake
The rate at which oxygen is taken up by the body to provide the energy needed for exercise, usually given in milliliters of oxygen consumed in 1 minute by 1 kilogram weight of tissue (e.g. mL/(kg*min)). The learner should compare the runners' performance relative to their VO2. Each person has a maximum rate that is the primary determinant of their level of aerobic fitness. This maximum rate is referred to as VO2max.
% of VO2 max
The maximum rate of oxygen consumption as measured during incremental exercise. VO2max reflects the aerobic physical fitness of the individual, and is an important determinant of their endurance capacity during prolonged, sub-maximal exercise. Knowing the percentage of VO2max is helpful when comparing the performance of endurance athletes because it is an indication of the relative exercise intensity for each person. Learners will see how effort and speed are affected by nearing VO2max.
Kilocalorie Burn Rate
A calorie is a unit of energy. The calorie is the approximate amount of energy needed to raise the temperature of one gram of water by one degree Celsius. Energy for running is thought of in terms of kilocalories (1,000 calories = 1 kilocalorie). The rate of kilocalories burned per minute is displayed for the avatar. The learner should note how many kilocalories are burned at different speeds.
Lactate Build-up
Lactate is an anion of lactic acid and its salts, which is released from the muscles into the blood. This occurs at greater rates when the energy demands of exercise approach or exceed the runner's upper aerobic limit. Because relatively greater lactate concentrations are associated with fatigue, this substance is an excellent marker of the body's fatigue "danger zone." You should try to avoid levels of lactate nearing 12.5mM/L or the runner will collapse.
Heart Rate
Heart rate is the number of heartbeats per minute. As the runners become more fit, the number of beats per minute required to maintain a given running speed gradually decreases.
Runner's Profile
Each runner or avatar has a different profile. The profile shows the runner's information regarding current fitness level, which includes the level of prior training, age, weight, onset of blood lactate accumulation (OBLA), and VO2max. The learner should compare each of the runners' profiles with their results before and after training.
Training Session
Each row of the table is another training session on the marathon course. There can be only one training session per day. You can click "view" in the details column to see how your avatar did minute by minute.
Training Impulse (also called "TRIMP")
TRIMPs accumulate during each minute of training and reflect gains in the runner's performance. It is not an exact measurement but has value when used to see the physiological/chemical adaptations that occur as a result of training.
Distance
Distance is measured in meters. The goal of the runner does not need to be 42.195 kilometers on each run. Find out what distance per run will give you the best results over time.
Average Speed
Speed is measured in meters per minute. The speed is closely tied to the effort level and the runner’s ability. Note how the speed and other parameters change with each effort level.
Average Effort
Average effort is selected by the learner and is closely tied to the runner's speed and heart rate. Determine the level of intensity (effort) from 1 to 10 and see how the runner responds. As the runners reach their maximum effort, levels of 0.5 start to appear. See if you can push through without overexertion or collapse.
Outcome
You have been training on the marathon course with the goal of finishing in an energetic and healthy state of being. This "outcome" field on the table reminds you of what happened at the end of your training for that day. The options are "stopped" (prior to 42.195 meters or after 8 hours), "collapsed" (at any point during the run), and "completed" (the entire course).
VO2 max
The maximum amount of oxygen an individual can utilize during intense exercise. VO2max is expressed as a relative rate in milliliters of oxygen per kilogram of body mass per minute (mL/(kg·min)). At this point, no matter how hard the runner pushes, his or her oxygen intake does not increase.
OBLA
OBLA stands for "Onset of Blood Lactate Accumulation." This is the point at which lactate is no longer being metabolized and starts to accumulate in the blood stream. As the runner trains, the OBLA happens later in the run or at a higher speed/effort.
Current Race
Displays the time elapsed, speed, and distance run in the current training session. When the runner stops running, the displays stop calculating progress and the runner walks. After stopping or finishing the distance, there is a 3 second delay before you can run again.
