An apparatus has a body configured to accept a portion of a forearm therein and configured to restrict movement of the forearm, a handle connected to the body, the handle configured for being gripped by a hand, and a first side extension connected to the body and extending generally radially from the body.

A flotation device, particularly suitable for use as a pull buoy or a kickboard is described. The flotation device can include a flotation element and a stem element, which extends from an inner surface of the flotation element. A holding mechanism can be located adjacent to the second end of the stem element. The stem element and holding mechanism can be configured to enable a user to hold onto the flotation device at a point below the surface of the water for use as a kickboard or enable a user to secure the stem element of the flotation device between his/her legs for use as a pull buoy. An embodiment of the stem element can be tapered, which can create forces that assist the user in using the flotation device as either a pull buoy or a kickboard.

A fin assembly for aqua resistance exercise comprises a strap having an inner strap and an outer strap, and with fastener(s) provided to an outside of the inner strap and an inside of the outer strap to releasably attach the inner and outer straps together. One or more fins are received on the outer strap and a longitudinal position of the one or more fins is secured by engagement of the inner strap to the outer strap. The length of the inner strap is longer than a length of the outer strap, so that an extending end portion of the outer strap can overlap and engage an opposite end of the outer strap to secure the fin assembly about the user's limb.

The present disclosure relates to systems and methods for elastic delivery, processing, and storage for wearable devices based on system resources. For example, a wearable apparatus may have at least one battery; at least one sensor configured to measure at least one property associated with a user of the wearable apparatus; at least one memory storing measurements from the at least one sensor and instructions; at least one transmitter configured to send data to a device remote from the wearable apparatus; and at least one processor configured to execute the instructions to: receive, from the at least one battery, an indicator of a charge; and based on the received indicator, sending a command to the at least one sensor to operate in a low-power mode or a high-power mode, the low-power mode having. a lower sampling rate than the high-power mode.

The invention concerns a hand paddle for swimming that has an upper wall to which the distal portion of a user's arm is attached and a lower propulsion blade. The hand paddle is equipped with a device for holding the hand paddle on the user's arm having an aperture formed through the paddle and a member mounted movable in the aperture and having an interface that is arranged on top of the wall. The interface being arranged to receive at least one finger of the user and arranged to hold the finger against the interface, the member being equipped with an element elastically constraining the movement. The element is arranged between the blade and the member and is reversibly compressible between an extended state, in which the member is arranged in a low position holding the user's finger, and a compressed state in which the member is arranged in a high position placing the user's finger on the interface.
