Device and ergometer for determining a value that is representative of the accelerations in at least two directions extending perpendicularly to each other. The device provided with a sensor system in which the acceleration in each of the directions extending perpendicularly to each other can be converted into an electric signal. The value that is representative of the accelerations can be determined from the electric signals by the signal processing means. Prior to the signal processing means, the electric signals are added together by means of an adding element.Currents from piczoelectric accelerometers may be added to a total current wich is converted to a value indicating work or effort of the person carrying the device.

Procédé et appareil de définition et de détermination d'une valeur pour un paramètre d'une capacité anaérobie. Le paramètre de capacité anaérobie est défini comme étant le temps nécessaire pour user complètement la capacité anaérobie d'un sujet effectuant un exercice mécanique maximal dans des conditions contrôlées. Une valeur du paramètre de capacité anaérobie pour un sujet est générée à l'aide d'un système de test. Le système de test comprend un dispositif exerciseur (12), un capteur de caractéristique de la puissance (14) et une unité de traitement (16). L'exerciseur (12) comprend un composant mobile dont le mouvement peut représenter une mesure de distance. L'exerciseur crée une charge sur le sujet. Le capteur de caractéristique de puissance (14) est utilisé pour détecter le mouvement du composant mobile et la charge imposée sur le sujet. Des données caractéristiques de puissance, par exemple des données de mouvement et de charge, sont générées par le capteur de caractéristique de puissance. L'unité de traitement (16) est connectée au capteur de caractéristique de puissance (14) de sorte que des données caractéristiques de puissance et des signaux de commande sont tranférés entre l'unité de traitement et le capteur de caractéristique de puissance. L'amélioration dans le système de test consiste à inclure un programme de commande principale dans l'unité de traitement (16). Le programme de commande principale commande l'enregistrement des données caractéristiques de puissance pendant une période de test. Un ensemble de valeurs de puissance représentatives de la puissance requise pour déplacer le composant mobile est dérivé des données caractéristiques de puissance. Une valeur de capacité anaérobie est déterminée en analysant la chute logarithimique des valeurs de puissance dérivées. Le temps pour appauvrir complètement la fonction logarithmique approchant les valeurs de puissance dérivées constitue la valeur de capacité anaérobie. Des valeurs pour des paramètres tels que la puissance de la volonté, la

The invention determines an efficiency value (E) denoting preferably the relative period of muscle fibre activity during a recorded period of exercise, and a spatial value (S) representing the number of muscle fibres recruited during a movement as part of the exercise or of a muscle contraction, and a temporal value (T) representing the frequency with which muscle fibres are activated repeatedly during exercise, and finally combines the efficiency value (E), the spatial value (S) and the temporal value (T) by a mathematical operation to obtain an index value (ESTi) indicative of the fitness level of the individual. The obtained ESTi score is useful for assessing the training level of an animal or human individual and the individual's potential for different types of sports and other activity. Also the effect of past training or diet can be assessed, and the possible need for changes in training or diet can be assessed.

An adhesively coupled power-meter measures one or more of force, torque, power, and velocity of a mechanical arm. The power meter includes a plate with a first surface prepared for adhesively coupling to the mechanical arm. At least one strain gauge is physically coupled with a second surface, opposite the first, of the plate and with an orientation corresponding to an orientation of the adhesively coupled power meter such that mechanical forces are transferred from mechanical arm to the at least one strain gauge when the plate is adhesively coupled to the mechanical arm. The power meter also includes electronics for receiving a signal from the at least one strain gauge and for determining one or more of force, torque, power and velocity from the signal, and a wireless transmitter for transmitting one or more of force, torque, power and velocity to a receiving device.
