An activity monitor that is worn by a user for monitoring water-based activities. The activity monitor includes at least one motion sensor, a memory, a battery to power the monitor and a processor. The processor is operable to run an algorithm to calculate activity data based on an output from the motion sensor and to save the activity data to the memory. The monitor has a sleep mode in which the monitor consumes little or no battery power, a standby mode in which power consumption is higher than the sleep mode but in which the processor is not operating to calculate activity data and an active mode in which the processor is operating to calculate activity data. The activity monitor is responsive to a first trigger to switch from sleep mode to standby mode and responsive to a second, different trigger to switch from standby mode to active mode.

Disclosed is an swimming training apparatus, comprising a drive mechanism driven with electricity and a pumping execution mechanism, said drive mechanism and said pumping execution mechanism disposed separately and spaced apart, and connected by a connection pipeline or a transmission mechanism. The separation of the drive mechanism and the pumping execution mechanism ensures the separation of water and power in the swimming training apparatus and thus ensures the safe use of the swimming training apparatus.

A swimming wearable device comprises an upper body wearable device (100) and a lower limb wearable device (2). The upper body wearable device (100) is provided with an electronic airbag (11) and the lower limb wearable device (2) is provided with a muscle condition monitoring device (21). The muscle condition monitoring device (21) is connected by signal with the upper body wearable device (100) or with the electronic airbag (11) of the upper body wearable device (100). When detecting a muscle spasm in lower limb, the muscle condition monitoring device (21) sends a signal to the upper body wearable device (100) or the electronic airbag (11) of the upper body wearable device (100), so as to make the upper body wearable device (100) activate the electronic airbag (11) to open or to activate the electronic airbag (11) to open. The swimming wearable device can provide certain buoyancy for the swimmer at the occurrence of muscle cramp, thereby reducing drowning accidents and improve safety of swimming exercise. An upper limb wearable device is also provided.

A starting block (10) for swimming pools comprising a base portion (12), constrainable to the perimetrical structure of the swimming pool at one of its head vertical walls, an upper walkable portion (14), supported by the base portion (12), and one or more handgrips (16). To the starting block (10) there is operatively connected a means (18) for supporting the feet of the swimmer, provided with a moving system which allows such support means (18) to move between a first operating position, wherein such support means (18) leans against the head vertical wall so as to form a step which is inclined with respect to such head vertical wall and facing upwards, and a second rest position, wherein such support means (18) is outside the swimming pool and does not represent an obstacle for the swimmers who are inside the swimming pool or on the starting block (10).

The invention relates to a swimming starting block comprising a push-off plate for supporting at least feet of a swimmer during a start, as well as a sensor device which is connected to the push-off plate and which serves to detect at least changes in pressure on the push-off plate induced by the swimmer. The sensor device comprises a substantially elongated conductor for electromagnetic signals, which is connected with a first circumferential side to the push-off plate and with a second circumferential side, situated substantially opposite the first circumferential side, to a sensor-support plate arranged at a distance from the push-off plate and extending substantially parallel thereto. The push-off plate, in operation, is movable with respect to the sensor-support plate, under the influence of pressure changes induced by the swimmer, to induce a disturbance into electromagnetic signals sent through the conductor. The elongated conductor can be connected, at an end thereof, to a signal source for transmitting the electromagnetic signals through the conductor. The conductor can be connected, with a second end situated opposite the first end, to a signal detector, wherein the signal detector is arranged to detect disturbances in the electromagnetic signal.

A method, apparatuses, and a system for carrying out exercise-related processing are described. The apparatus includes an exercise-measurement circuitry configured to measure exercise-related measurement data related to a user carrying out an exercise. The apparatus further comprises a communication circuitry configured to provide the portable apparatus with wireless communication capability. The apparatus further comprises a processing circuitry configured to receive the exercise-related measurement data from the exercise-measurement circuitry, to process the exercise-related measurement data, and to communicate with an external user interface apparatus over a bidirectional wireless communication connection through the communication circuitry so as to cause transmission of the processed exercise-related measurement data to the user interface apparatus and to receive configuration data from the user interface apparatus.

The counting device for swimming pools, that counts swung swimming pool lengths, or two lengths, round trip, or exercises done in the swimming pools, and comprising placing means (3; 5), and it is characterised in that it comprises at least one guide (1) along which a plurality of counting elements (2) can slide. Said counting elements (2) are preferably of two or more different kinds to each other.

It permits to obtain a counting device of the swung swimming pool lengths, or exercises done, very simple and cheap, completely mechanical and that is accessible for any swimmer.
