Training devices are known in a variety of designs from the prior art, for example as a bicycle trainer, treadmill, crosstrainer and the like. A training device for simulating body movements in water sports is known for example from DE 20 2004 003 201 U1.

In order to monitor a training and / or to evaluate training successes, it is known to form and / or couple the training device with a device for processing measurement signals. Known devices are integrated, for example, in the training device and are preferably also used as a control unit. In other Embodiments are provided separate units, which are coupled to the training device and / or a person training for signal transmission.

It is known to detect and / or evaluate a training provided by a training person training performance. For this purpose, various methods are known, for example, to determine an acceleration performance and / or a braking performance of the training device. Training devices in which a given instantaneous power in watts can be displayed, are also referred to as ergometers.

In addition, it is known to detect and / or evaluate physiological signals, such as a heart rate, a pulse rate, a respiratory rate and / or an EEG frequency, of a person exercising. By measuring and evaluating physiological signals, it is possible to monitor a workout. For example, a person exercising is instructed to train with a specific heart rate and / or below a maximum heart rate.

It is an object of the present invention to provide a device, a training device and a method by which a trainee is better supported in monitoring the training.

This object is achieved by the objects having the features of claims 1, 4, 8, 13 and 14. Further advantages of the invention will become apparent from the dependent claims.

The computing unit for determining the degree of performance comprises in advantageous embodiments hardware elements and / or software elements, and is in particular designed as a semiconductor component, integrated circuit and / or electronic circuit. The arithmetic unit and the detection unit are at least partially designed as a common component in one embodiment.

The training performance provided can be determined by a method adapted to the training device. As training performance is in the context of the invention, both an applied energy or work, as well as a power, d. H. an applied energy or power per unit time.

Depending on the device, an applied energy or work or an applied power can be detected as a training performance. In advantageous embodiments, the training device comprises a rotationally drivable aerodynamic braking device. A detected rotational speed and the braking power are in a clearly attributable physical relationship, wherein the power required for acceleration corresponds to the braking power through the aerodynamic braking device.

To record the physiological training intensity, for example, a heart rate, a pulse rate, a respiratory rate, and / or an EEG frequency of a person exercising is detected. During training, the physiological training intensity is generally increased, ie a heart rate, a pulse rate and / or a respiratory rate rises. Upon reaching a performance limit of the exercising person, the physiological training intensity continues to increase, while the power provided by it is increased only insignificantly or remains constant. According to the invention, the power delivered to the training device is weighted on the basis of the training intensity and thus a degree of performance is determined. A highly achievable by the exercising person high degree of achievement allows a high endurance performance. An exercising person is thus supported by the inventive recording of the degree of performance in an endurance training.

In advantageous embodiments, a heart rate and / or a pulse rate is detected to determine the physiological training intensity. Usually, the heart rate is equal to the pulse rate. Due to the Windkessel function, deviations may occur.
