The charts in Athlete Analyzer Judo Training Insights will give you a good insight in current and past fitness, fatigue, performance and injury risk for you or your athletes. You can use the graphs as a help to avoid over training and also plan tapering before competitions. The graphs are indicative tools and do not provide an absolute truth as there are several other parameters that can affect the actual form as nutrition, sleep etc.
Training Load (TL)
Training Load is based on (Session RPE x Minutes) / 2 giving a Training Load Value for each of the athlete’s workouts.
For a workout of 60 minutes at a sRPE of 15 the Training Load will be ((15 x 60) / 2) = 450.
Session RPE (sRPE)
Every workout has a planned exertion ranging from 0 to 20 based on “Session RPE” (Rating of Perceived Exertion). When the workout is performed the athletes report their actual Session RPE using the table below as a reference. It is very important that sRPE is reported as carefully as possible for the analyses to be accurate. The reported sRPE should reflect the whole workout, not only the hardest exercise in the workout.
Fitness, fatigue & performance
The analysis model assume that training has both a positive and a negative effect. The positive effect is called Fitness and the negative effect is called “fatigue”. They are combined to provide “Performance”.
Fitness (or Chronic Training Load, CTL) represent the amount of training (Training Load, TL) you have done the last 42 days. Fitness is displayed as green in the graph.
Fatigue (or Acute Training Load, ATL) represent the fatigue you have built based on the amount of training (Training Load, TL) the last 7 days. Fatigue is displayed as red in the graph.
In other words, a workout session benefits your fitness and is declining during 42 days but also affects you fatigue level which will decline during 7 days.
Performance (or readiness to perform, or in short, Form) is calculated by subtracting your current Fatigue from your current Fitness (CTL-ATL). After a week with higher TL than usual your Form will be below zero. A week with reduced workload will bring your Form up over zero which is used for tapering before competitions. Please notice that future planned workouts also are shown in the graph as dotted lines as a guidance for tapering planning. Form is displayed as blue in the graph.
You can also see competitions as yellow dots attached to the Form. Hover over the graph to see the details. Click on the legends to show/remove graph lines.
Injury risk (acute:chronic workload)
Recent studies (Gabbet et all, Link) shows that the ratio between chronic and acute training load is one of the best predictors of injury. If you increase your training load significantly compared to the weeks before you are more in risk for an injury. A high ratio means that you’re training too much with regard to how much you are used to (a high fatigue and a low fitness).
A ratio below 0.8 indicates that your fitness level are going down due to not enough training.
A ratio between 0.8 – 1.3 is an optimal area for your training, trigging positive adaptions and is displayed as green in the graph.
A ratio between 1.3 – 1.5 implicates a moderate risk for injuries and is displayed as yellow in the graph.
A ratio over 1.5 implicates a high risk for injuries and is displayed as red in the graph.
Please remember that these ratios are no absolutely truth because many other parameters can affect the actual injury risk but it can be an indicative tool for avoid over training especially after recent injuries or training breaks etc.
Please notice that future planned workouts also are shown in the graph as grey bars.
