VALD ForceDecks for Enhanced Performance Analysis and Injury Risk Analysis

What are VALD ForceDecks?

VALD ForceDecks are a Dual Plate system which have the ability to record your strength while practising in certain movements and muscles groups, specific to your exercise and sport. They detect movement from particular exercises and tests, and then visually translates the real-time data which provides in-depth data analysis for your performance and injury risk assessment.

How is the data shown?

The objective data is displayed on detailed graphs with metrics in real time. You will be given a report and summary of the results specific to your injury and sport/exercise. This objective data creates a picture of your ability to balance and how strong/powerful you are.

Why is the data important for me?

The data will form part of your rehabilitation sessions providing the answers, direction and confidence to achieve your goals. We will be able to accurately assess:

The initial data recorded at the start of your injury rehabilitation journey will provide information on what you are capable of doing now, we can then compare this to the non-injured side and normative data for your sport. We can set specific goals in combination with an injury rehabilitation programme.

At a later stage we will retest to see your progress, and how safe it is for you to return to sport.

What are metrics and which ones will be analysed?

Metrics are used to track and compare performance of quantitative assessment. Common metrics are distance (mile/kilometer), or duration (minutes/hours).

There are many different metrics used in the ForceDecks performance analysis, however, only the relevant ones will be selected for your goals and injury. Common metrics recorded are:

1. Rate of Force Development (RfD)

How quick (seconds) you can produce your maximal force (newtons). For example, how quickly you can push into the ForceDecks with your shoulder during an ASH Test.

2. Concentric Peak Force

Your maximal force produced when jumping into the air from the ForceDecks during a Counter Movement Jump (CMJ) test.

3. Jump Height

How high you can jump (cm) during a Drop Jump (DJ) or Single Leg Drop Jump (SLDJ).

Which injuries are the ForceDecks most effective for?

The data can be used for both acute and chronic injuries regardless of severity. From muscle/tendon strains & ligament sprains, to ongoing tendon related pain or biomechanical dysfunction.

We can assess the performance of your lower limb muscles (hamstrings, calves, quadriceps), shoulder and back, once you are fit enough to do the tests, as they are maximal force. Injuries include:

Who will benefit from ForceDecks?

Anyone from all ages can benefit from the Force Decks, from a complete novice to sport/exercise to very experienced. The data will show the results that are specific to your goals and needs. Specifically, the Force Decks will help those who want to improve their sport and exercise performance. This includes:


Measure how quick you can produce force for your sport, vertical jump height and how well you can absorb and release load for assessing injury risk.


Assess the quality of your balance, ability to land and hop to the side, and how fast and jump on one or both legs for heading/competing for the ball.


Improve your club head speed, or find out why you experience pain/symptoms during or after a round. Find out which muscle group or movement is affecting your performance.


Record your one rep max for Deadlifts/Squats, Bench Press and more. Analyse which side works the most during compound lifts, shoulders and hamstrings. You can also find out how long you can hold you maximal force.

Pre-Post surgery

Discover the differences between injured & non-injured limbs pre-surgery and create clear goals for a safe return to exercise, sport or lifestyle post surgery.


Measure the ability of your legs & shoulders to improve your tackle technique, running, agility, scrummaging power, leg/shoulder strength for line-out lifting, and single leg stability to change direction for a tackle or landing from a high ball.

Running, Marathons, Triathlons & Cycling

Establish which leg is weaker and at greater risk of injury before or during training for an event/season. Analyse strength and load capacity of muscle groups (gluteals, hamstrings, quads & calves) and compare L & R leg/shoulder.

Sports Clubs

Players can be tested in groups for a range of tests. The Force Decks are portable and can be used indoor and outdoor. Group testing is great for inter club competition, and recording progress for preseason.


Measure your ability to land vertically and laterally and how you can transfer weight side to side on each leg to see how you move across the court.
