Aerobic Training Effect (Aerobic TE) – Aerobic Training Effect describes the impact of a training session on the development of VO2max and aerobic endurance capabilities. Its quantification is based on the highest level of EPOC achieved during the session. Read more here.
Anaerobic Training Effect (Anaerobic TE) – Anaerobic Training Effect describes the impact of a training session on the development of repeated sprinting abilities and anaerobic performance capacity. Read more here.
TRIMP – Training Impulse, a measure to quantify internal training load. Read more here.
Stress Reactions – An elevated activation level in the body not caused by physical activity. Stress is characterized by sympathetic predominance of the body, and the reaction can be positive (e.g. excitement, happiness) or negative (e.g. anger, anxiety).
Movement Load – This is used to quantify the movement of an athlete during a session, the External Load equivalent of TRIMP. Read more here.
Training Status – The Training Status metric takes multiple variables to provide a picture of how well balanced an individual’s training has been. Read more here.
Balanced Range – Calculated using the Chronic (28 Day) Training Load, this acts as a guide for the Acute Load that can be tolerated by your team. By staying within the range, your training load is not increasing too quickly.
Load Ratio – See Acute:Chronic Workload Ratio.
Workload – The sport-specific stressors placed upon the athlete, i.e. training and competition. High workload is not necessarily a risk factor for injury. Indeed, evidence suggests it may even be protective.
Acute:Chronic Workload Ratio (ACWR) – The ratio between acute and chronic training loads. High ACWR shows the athlete has an increased acute training load relative to their chronic, placing them at increased risk of injury. Conversely, a low ACWR may also present increased risk due to the athlete being underprepared. A sweet spot of ACWR is the area in which the athlete has developed sufficient fitness over time to effectively cope with their current workload. The ACWR can be used to guide the safe achievement of high workload.
Load-Recovery Relationship – The way in which an athlete’s load and recovery are managed. Sufficient recovery is necessary for the process of supercompensation and positive adaption to occur. Poor load management and insufficient recovery ultimately results in increased risk of injury.
Internal Load – This is the physiological or psychological response to completing the work described under External Load. An example of internal load could be elevated heart rate, or the accumulation of Excess Post-Exercise Oxygen Consumption (EPOC).
External Load – The act of performing work or carrying out a task. An example of external load could be Movement Load from Firstbeat or the data recorded via a third-party GPS system (which captures the distances covered and the speeds attained, or the accelerations and decelerations).
Load Tolerance – The ability of an athlete to cope with any given training load. This can be influenced by many external factors, such stress from family, lifestyle or work, or quality and duration of sleep.
Maximal Intensity Period – Sometimes also called “Worst-Case Scenario”, this reflects the highest intensity experienced over the selected measurement/session for the stated duration. For example, the highest TRIMP/min an athlete recorded over any 4 minute period.
