A swim paddle system includes a substantially planar, rigid paddle having a first side for receiving a hand of a swimmer and a second side opposing the first side with a plurality of through holes extending through the paddle from the first side to the second side, the first side having a palm region for receiving a palm of the hand and a peripheral region for receiving a thumb, an index finger, a middle finger, a ring finger, a little finger, and a wrist of the hand. At least a portion of the paddle is transparent or translucent to allow at least a portion of the hand to cast a shadow as light shines through the paddle.

A method of coupling a boot toe body to a fin apparatus is disclosed. The fin apparatus includes a fin body coupled to a boot coupling body. The method involves connecting a first boot connector on a first end of the boot coupling body to a first complementary boot connector on a top side of the boot toe body, and connecting a second boot connector on a second end of the boot coupling body to a second complementary boot connector on a bottom side of the boot toe body. Boot toe bodies, fin apparatuses, and systems including the boot toe bodies and fin apparatuses are also disclosed.

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.

An aquatic training aid includes a paddle member for wearing by a swimmer, a variable diaphragm disposed within the paddle member, the variable diaphragm including a plurality of fitted blades arranged to form an aperture, and a housing peripherally framing the plurality of fitted blades. The variable diaphragm is adjustable to change the aperture from a first expanded position to a second contracted position, and hydrodynamic characteristics of the aquatic training aid when moved through water are affected by the change of the aperture. Controlling the aperture enables the swimmer to adjust the resistance provided by the aquatic training aid when it is moved through water.

Enhanced surfing by means of waterproof gloves which provide lifting pads spanning the width of the palm from the base of the thumb and terminating near the pinky, or also extending across the upper palm finger pads if desirable, while secured tightly at the wrist. The padding is contoured and rises to prescribed height starting at the base of the wrist, rising to the maximum height near the base of the palm, and then returning to level with the hand inside the palm. Similarly, narrower finger pads will follow a similar contour but will have less height than the palm pad. The padding provides a resilient, rebound boost to aid surfers in quickly rising to their feet while simultaneously creating more clearance between a surfer's torso and board to allow for a heightened swing arch to create forward distance for initial foot positioning and added takeoff momentum.

A hand control device for swimmers is presented. The device has a main body with two holes in a side-by-side configuration. The first one of the two holes is configured for a third digit of a person's hand while the second one of the two holes is configured for a fourth digit of the person's hand. The inside surface of each hole comprises a plurality of grooves that run depthwise thereby providing wet traction while impacting minimum direct pressure on the nerves, vessels and tendons. The outside surface of the device may also include ridges to provide pass through for water.
