Method and an apparatus for determining training status
A method and apparatus for determining training status from a group of alternatives from a plurality of exercises, where a user has frequently monitored exercises with at least heart rate being measured by a host process, which outputs selected variables for calculating the training status by a child process.
1. A method for determining a training status of a user from plurality of exercises using a device with a heart rate sensor, a processor, memory, and software, the determined training status being selected from a fixed group of alternatives depicting a unique physical condition of the user,
wherein heart rate data is recorded during each exercise using the heart rate sensor, and chosen exercise characteristics of each executed exercise are determined using recorded heart rate data, and after each exercise the determined characteristics of each executed exercise are stored in the memory, the chosen exercise characteristics including values of at least the following variables:
a date of the exercise,
a value depicting physical readiness level in terms of a VO2max-value for exercise during the exercise; and
a value depicting a training load of the exercise,
wherein when the plurality of exercises have been executed, values of selection variables are calculated using the stored exercise characteristics in the memory, and
the training status is determined using sequential pre-determined selection rules, each rule being connected to one unique variable of said selection variables, wherein each selection rule uses a calculated value of its selection variable to limit a number of remaining alternatives and, after all selection rules have been sequentially used, only one alternative is selected.
2. A method according to claim 1 , wherein there are three selection rules with three selection variables, namely a fitness level (VO2max) trend, a weekly training load (WTL) and a WTL trend.
3. The method according to claim 1 , wherein the variable of the training load is a peak value regarding a training effect measured as a disturbance level of homeostasis.
4. The method according to claim 1 , wherein the number of training status alternatives is at least 5, these alternatives comprising at least Detraining, Maintaining, Recovery, Overreaching and Productive.
5. The method according to claim 1 , wherein an output device is implemented in at least one of the following: a heart rate monitor, a fitness device, a mobile phone, a PDA device, a wrist top computer, a tablet computer or a personal computer.
6. The method according to claim 1 , further comprising a selection of additional information according to at least one additional variable depicting at least one of: anaerobic training effect, training variability or high intensity training count.
7. The method according to claim 1 , wherein a type of exercise is stored as part of the characteristics of each exercise.
8. The method according to claim 7 , wherein at least one selection variable is calculated using data of a same exercise type.
9. The method according claim 1 , wherein values of selected variables of each day are recorded and summed in a sliding window of a plurality of past days, the selected variables including at least a highest VO2max, its type of exercise, a sum of peaks of training loads, and the VO2max trend being calculated from the values of the highest VO2max of a same type.
10. An apparatus for determining a training status of a user from a plurality of exercises using a device with a heart rate sensor, the device having a processor, memory, resident memory and software, the determined training status being an alternative of a fixed group of alternatives each of them depicting a unique physical condition of the user,
said software being arranged to monitor each exercise using the heart rate sensor and to determine chosen exercise characteristics of each executed exercise and store them in a resident memory, the chosen exercise characteristics including values of at least:
a date of the exercise,
a value depicting readiness level in terms of a VO2max-value for exercise during the exercise; and
a value depicting a training load of the exercise
said software is adapted to validate the training status calculation, when the plurality of exercises has been executed and calculate values of selection variables using the stored exercise characteristics in the resident memory, and
when called, determine the training status using sequential pre-determined selection rules, each rule being connected to one unique variable of said selection variables, where each selection rule using a calculated value of its selection variable is limiting the number of remaining alternatives and to select one alternative representing the training status after all selection rules have been sequentially used.
11. The apparatus according to claim 10 , wherein the apparatus is at least one of: a heart rate monitor, a fitness device, a mobile phone, a PDA device, a wrist top computer, a tablet computer or a personal computer.
12. The apparatus according to claim 10 , wherein a dynamic memory in a RAM memory is allocated 100-400 bytes (×8 bits) for calculation of training status in a child process.
13. The apparatus according to claim 10 , wherein the software includes a basic library (ETE) for monitoring the exercises and determining characteristics of the plurality of exercises in a host process using a memory dynamic and storing the exercise characteristics in a resident memory, and an auxiliary library software (THA) to determine the training status as a child process using characteristics in the resident memory.
