Strength Testing Equipment for Reliable Performance Data

The best way to test your strength is to create a load–velocity profile. Rather than seeing strength as a singular measure of how much you can lift in one repetition, a load–velocity profile shows how you perform across a range of loads. With Output, this can be done quickly and safely, predicting your one-rep max without the risks of max testing. This gives a clearer picture of your strength and highlights exactly where you should focus your training.

Muscle strength can be tested with a range of tools, from handheld dynamometers to barbells for rep max testing or even lab-based force plates. A more modern option is Output’s wearable IMU, which is portable, versatile, and research-validated. It captures strength metrics in real time and even allows safe one-rep max estimations from sub-maximal loads. This means you can test consistently in the gym, on the field, or during rehab without the risks of traditional max testing.

The traditional gold standards for strength testing include isokinetic dynamometry and force plates, both highly accurate but expensive and less portable. Research shows IMU technology, like Output, provides valid and reliable strength metrics in more accessible setups. With robust calibration, accuracy, and ongoing support, Output delivers strength data that can be integrated seamlessly into daily coaching workflows.

Physical strength often peaks between the mid-20s and early 30s, although this varies by muscle group, training history, and genetics. Tracking changes in strength over time is key to understanding individual potential and longevity. With Output’s hardware portability and easy setup, coaches can monitor metrics across age groups, from youth development to masters athletes, supporting strength at every stage.
