Systems and methods for evaluating the performance of an athlete using a strain gauge is described. In some embodiments, the measurement system comprises a strain gauge and a central processing device. The strain gauge can include a power source, an inertial measurement unit (“IMU”) comprising a load cell, a microcontroller, and a wireless communication module. The strain gauge can be configured to output strain data at a rate of at least 1 kHz and the central processing device can be configured to receive the strain data transmitted from the wireless communication module.

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 portable exercise resistance device that can be mounted to stabilized objects to maximize use in various locations is disclosed.

A motion assistance apparatus including a first support configured to support a waist of a user, a side frame connected to the first support and configured to cover at least a portion of a side of the waist, and a joint assembly connected to the side frame such that a location of the joint assembly is adjustable in a longitudinal direction of the side frame, and configured to be located at a part of a hip joint of the user is disclosed.

An exercise device for assisting a user in performing bodyweight exercises as well as being configured for performance of weight training cable exercises includes a frame that is configured to be detachably mounted to a doorframe. The frame includes a first door bar and a second door bar that is spaced from the first door bar and is configured for contacting the doorframe on a first side of the doorframe. The exercise device also includes a pair of door hook assemblies that are coupled to the frame and are configured to seat against a ledge of the doorframe on a second side of the doorframe for securely yet detachably mounting the frame to the doorframe. A pulley carrier assembly is detachably coupled to both the first door bar and the second door bar and includes an elongated carrier that carries a first pulley and a spaced second pulley. A cable passes along the first pulley and the second pulley and the cable has a first end and an opposing second end. The device also includes a counter-weight coupled to a first end of the cable.

A belt for use in performing hip raising exercises is provided. The hip thrust belt of the present invention comprises a flexible supporting pad coupled to a flexible belt. Hook-and-loop fasteners are provided on the belt to secure the ends of the belt to dumbbells or other weights including barbell weight plates and kettlebells. The hip thrust belt allows the weights to hang on the outer sides of the user's hip and thereby increases the effort required to perform hip raising exercises. Hip raising exercises are believed to strengthen the gluteal and hamstring muscles.

A walking assistance device includes: a belt-shaped lumbar region fixture wound around a lumbar region; a first elastic string-like member an upper part of which is fixed to the lumbar region fixture at a position of an anterior superior iliac spine and a lower part of which extends in an instep direction of a leg and is hooked to a toe region of a sole; and a second elastic string-like member an upper part of which is fixed to the lumbar region fixture above a position of an ischial tuberosity and a lower part of which extends in an ankle direction and is hooked to a heel region of the sole, wherein each of the first elastic string-like member and the second elastic string-like member is bifurcated near a knee of a leg, and the bifurcated parts of the first elastic string-like member and the second elastic string-like member are bound to each other at positions of an outer knee joint fissure gap and an inner knee joint fissure gap.

A cycling system includes a cycle having a frame with a resistance element attachment point, a resistance element, and a harness. The harness is releasably secured to the resistance element attachment point by the resistance element.

Disclosed is a technical training garment configured for use with modular, interchangeable electronics and resistance modules. The garment provides resistance to movement throughout an angular range of motion and tracks biomechanical parameters such as stride length, stride rate, angular velocity and incremental power expended by the wearer. The garment may be low profile, and worn by a wearer as a primary garment or beneath or over conventional clothing. Alternatively, the device may be worn as a supplemental training tool during conventional training protocols.

A system and process for training a user's sports swing to maintain arm position and body rotation so as to promote a proper swing arc. The system includes a waist wrap having one or more attachment area on an outer surface. The system also includes one or more training blocks configured for attachment to the attachment area depending upon the type of swing being practices. The process promotes a proper swing arc by indicating incorrect arm position and/or body rotation through excessive contact between the user's arms and the training blocks during the swing. The goal of the system and process is to train a user's muscle memory for the correct arm position and body rotation in a proper swing arc.
