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 training sled configurable for adding weights in some embodiments to increase friction and provide for weight-training by lifting portions of the sled. Sled components are slidably or pivotably connected to permit lifting a shoulder member of the sled to different heights and to achieve an optimal training angle. The training sled having an accelerometer, sensor unit and display for sensing, determining and displaying the force of impact and movement of the training sled.

Apparatus is provided for training people in technique and tactics for use in wrestling and other combat sports. The apparatus presented comprises a rigid and elastic frame, padding, low-friction feet or runners, and a platform for another user or weights, to add mass and resistance for the user training with the apparatus. A user may use the apparatus to practice penetration techniques, agility, and strength while training in free motion. The apparatus leads the user to use her or his body weight, the weight of the apparatus, and optionally added weight, in training while on matted surfaces, providing a better training experience and practice than prior art training devices. The present invention solves problems with the currently available means and apparatuses of practicing penetration techniques and tactics.

An exercise apparatus with base horizontal members forming a base polygon and ceiling horizontal members forming a ceiling polygon and a plurality of vertical members mounted at their lower ends to the base polygon and mounting the ceiling polygon spaced from the base polygon. A human interface permits athletes to exercise, and wheels mounted to the base polygon permit transport of the apparatus and attached equipment to a field or court. The base polygon includes two parallel skids and the human interface may be a pad permitting an athlete to push the apparatus horizontally when none or two of the wheels contact the ground. When no wheels contact the ground, the apparatus may be used in the manner of a weight rack, because the apparatus will not move along the ground without substantial force being applied.

A multi-purpose balance exercise device designed to be used in multiple positions and for diverse exercises. For example, various embodiments allow for the device to be used as an aerobic step device as well as the ability to easily adjust the device to various heights to easily decrease the level of difficulty of the device for use during various exercises. The balance exercise device can provide a plurality of handles and grab points both horizontally and vertically, which allow for an enhanced number of exercises or movements using either the top and/or bottom of the device. The exercise device includes a flexible bladder filled with air, other gases, or gels attached to a substantially rigid base. The base can include an interior within which features such as handles are disposed to provide a gripping or lifting exercise for which the balance exercise device can be used.

A weightlifting and strength training apparatus intended for a full body workout. The weightlifting apparatus combines the weightlifting aspects of a yoke with the resistance training of a sled.

An exercise training device includes a sled portion extending along a first plane that is substantially parallel to a surface upon which the exercise training device is supported. The sled portion includes a first side that is in contact with the surface. A support structure, attached to the sled portion, includes a support surface that extends along a second plane that is substantially parallel to the first plane. The support surface supports an exercise weight. A handle portion is attached to one of the sled portion or the support structure, the handle portion allows a user to grip the exercise training device and move the exercise training device along the surface.

A sledmill exercise apparatus. The apparatus has a frame with two spaced apart upright supports, which is stabilized to prevent tipping. The frame has a spacer bar between the supports and is moveably connected to it to vary the distance between the bar and the ground. The frame has two handles moveably connected to the bar to vary the distance between the handles. The bar is lockable in one position and the handles are lockable in a holding position. An endless drive belt with a driving surface contacts a user's foot. The supports are sufficiently spaced apart to permit location of the belt adjacent the frame. The bar position and the holding position are such that the user achieves a desired biomechanical position which allows forward and backward resistant movement of the belt relative to the frame.

A garment attachable to an exercise or therapeutic apparatus that is capable of elevating the user slightly above the ground, reducing potential for injury and strain by shifting the user's weight to the frame of the apparatus. The garment is incorporated into the apparatus by comprising panels under the buttocks and around the thighs, providing balance and lifting the user comfortably in conjunction with the frame. A low-friction plate is positioned under the user's feet so that the user can ambulate freely while held in place by the frame.
