SUSPENSION TRAINING TRACKING DEVICE
FIELD OF THE INVENTION
The present invention relates to suspension training exercise apparatus in general and in particular to apparatus and methods for tracking suspension training exercise loads.
BACKGROUND OF THE INVENTION
Suspension training US patent: US8469864 B2, US patent: US201 10124477 A1 is a form of resistance training in which the subject can manipulate total resistance by altering the position of the body in respect to anchor point. Different exercises are performed by manipulating body positioning and different loads are achieved by changing the angle of the body relative to the ground. Changing the length of the moment arm (levers) and positioning of the base of support relative to the center of gravity determines the stability. Multiple studies have shown that instability increases the core body strength (Beach, T.A.C., Howarth, S.J., & Callaghan, J. P., 2008) and sport performance (Kean, C, Behm, D., Young, W., 2006).
Instability and undefined weight in suspension training can be a cause of potential problems. There is a potential for muscular, skeletal and joint injuries, particularly hyperextensions of wrists, elbows, shoulders, ankles and knees. Undertrained people are especially prone to injuries since they don't have sufficient single joint stabilisation ability and the necessary skill to stabilize their entire body. Suspension training specific, exercise monitoring systems which track a user's progress and performance on suspension training exercise equipment are not known. Traditional measurement devices, such as heart rate monitors, accelerometers, spirometers, electromyographic measurement systems (Snarr, & Esco, 2013) and motion-capture systems can all be applied to monitor the performance during the suspension training exercise, however they all have several limitations. These systems may provide information concerning muscle activity, overall fitness performance, calories, etc, but that information cannot include or be based upon load measurements and thus may not be as accurate as values derived from or taking into account loads during suspension training exercise.
Measuring heart rate provides useful information for monitoring performance of cardiovascular system and energy supplying systems for muscle function, however it is not as good as measuring loads in providing consistent and useful information regarding muscular force performance. For example, during rapid movements, heart rate lags behind the user's effort whereas information about load during exercise provides a nearly instantaneous reflection of the user's muscular force exertion. When a user is dehydrated, tired, injured and malnourished or otherwise not in optimal exercising condition, the user may conduct a workout at a typical heart rate but their load at that heart rate may be considerably less than typical. Thus, the user or his coach can identify and possibly rectify substantial deviations from the optimal suspension training performance if load measurements are available. Inertial tracking technology has attracted considerable interest since accelerometer technology has advanced significantly, making these devices small, light and portable enough to be placed on the body or device. Because of the nature of suspension training exercises the accelerations should be small, making accelerometers alone inadequate for measuring them.
Measuring oxygen consumption provides an estimation of aerobic capacity. There are number of factors that are influencing measurements: age, sex, fitness and training, changes in altitude, and activity of the respiratory muscles making them unsuitable to quantify muscular exertion during suspension training exercise.
The eletromyography (EMG) only provides an interferogram that represents the summated electrical activation pattern of the muscle near the electrode. As muscle force is highly dependent on length (due to the length-force property) and velocity (due to the force-velocity property), electrical activity alone cannot provide an accurate measurement of muscle force. One of the limitations of an interference EMG is the variability in the recording when the same task is performed by different subjects or by the same subject on different days. Two principal reasons for this variability are that the recording conditions change each time the electrodes are attached the skin over selected muscle(s) and that the volume recorded by the electrodes does not cover the whole volume of the muscle involved in the task.
The biggest drawback overall of motion capture systems is high cost and lack of portability. Measuring and comparing training loads over an extended period of training can help identify a user (or his coach) the most suitable exercises and thereby continually refine and improve a performer's training regimen. Furthermore the above mentioned systems are difficult to install and with some systems, in- depth knowledge is needed for proper usage. The main technical purpose of the present invention is to overcome the above mentioned disadvantages by providing a method and a device for analysing and tracking exercise done by a user that can precisely and accurately record the suspension training exercises.

The present invention provides a novel system and a method which provides suspension training specific information and overcomes the known disadvantages of the prior methods discussed above. Moreover in accordance with a preferred embodiment of the present invention the suspension training exercise monitoring apparatus and method includes a force measurement sensor to determine a measurement of user caused load on suspension training exercise apparatus that interacts with a user or his trainer.
Additionally the tracking apparatus may include an accelerometer to determine a measurement of movement and vibrations and or additional external sensors such as ECG, EMG, heart rate.
Further in accordance with a preferred embodiment of the present invention the tracking apparatus includes a unit that processes raw-measured data of exercise loads into user friendly results that are easy to interpret.
