A resistive training device to be worn by a user can include a first and second skate device configured to be worn on the user's feet. The first and second skate device can include a first plurality of attachment mechanisms. The first plurality of attachment mechanisms can include an interior attachment mechanism; an exterior attachment mechanism; and a rear attachment mechanism. The resistive training device can also include a belt configured to be worn around the user's waist. The belt can include comprising a second plurality of attachment mechanisms which can include a left hip attachment mechanism; a right hip attachment mechanism; and a tailbone attachment mechanism. The resistive training device can also include a plurality of resistive elements. Each resistive element can be removably connected to one of the first plurality of attachment mechanisms and one of the second plurality of attachment mechanisms.

A method of playing a game, comprising providing a playing surface that is generally rectangular with rounded corners having a length dimension of approximately 200 feet or less and a width dimension of approximately 85 feet or less, providing a pair of opposing goal nets, each associated with one end of the playing surface where each goal net defines a scoring area above said playing surface. providing a first team and a second team of players, each team alternatively having possession of the game ball and having an objective to score points by sending the game ball into the goal net. providing the first team and the second team each include six players and a goalie, where each of the six players wear inline skates except the goalies where players from the first team and the second team are free to collect the game ball after deflecting off the barrier.

Wearable electronic devices that are designed to be worn on the head of a user while the user is swimming can determine swimming strokes and swimming performances of the user using motion sensors. Using a sound speaker, the wearable electronic device can play music and provide audio feedback to the swimmer. By comparing the swimming performance of the swimmer wearing the device with previously recorded swimming data, the wearable electronic device can provide audio comparison results to the swimmer while the swimmer is swimming in water. The wearable electronic device can also support similar functions for jumping actions.

Described herein is a modular skate system that includes at least one modular skate component comprising a major surface, a core comprising a body formed from a first material, an outer layer formed from a second material, the outer layer surrounding at least a portion of the core, wherein the first material is different from the second material, and wherein the major surface comprises the outer layer.

The invention relates to a board for a sports facility comprising a handrail at its upper edge, the handrail having a handrail body having a profile extending in a longitudinal direction, in the outer surface of which a mounting channel runs essentially over the entire length of the handrail, which mounting channel is designed to mount a flat information element. The invention further relates to such a handrail for a board, a mobile sports facility and a method for constructing a mobile sports facility.

A convertible training aid for multi-stage development of a skater is disclosed. The training aid includes a frame with front, back, and opposing sides. The frame has an upper frame that surrounds the skater, a lower frame, and a plurality of support posts. Each of the opposing sides of the frame comprises a front side portion and a back side portion. The front side portion is detachably coupled to the back side portion. A seat is detachably suspended from the frame and disposed at a position below the upper frame. The seat has an adjustable height. The first stage training aid described above can be converted into a second stage training aid by removing the seat from the frame and removing the back of the frame and the back side portions of the opposing sides of the frame from the front of the frame and the front side portions of the opposing sides of the frame.
