Development Score (shown as a % on shields across the portal)


We've devised a development score using a formula that monitors an athlete's progress relative to the organizational standards set for their specific position category, such as U18 Tighthead Prop.



To illustrate, when an athlete participates in MVP's testing day and completes five different tests, each test comprising three levels (below standard, achievable standard, and desirable standard), we employ a point system to calculate the development score.



Scoring the 'Achievable' standard in all tests earns them 1 point per test, resulting in a 50% development score. Attaining the desirable standard in all tests gives them 2 points per test, equating to a 100% development score. If an athlete has performed 20/48 tests, they may still score 100% if they have attained 'Desirable' on all of the tests they have completed.



The metrics influencing the development score have been carefully chosen to offer a comprehensive evaluation of the athlete's performance. The selected tests focus on various "performance" elements, including Bronco, Speed (40m Max Velocity), Counter Movement Jump (CMJ) - Jump height, CMJ - Relative Peak Power, CMJ - Peak Power, CMJ - RSI mod.

Glossary


CMJ - Peak Power (W)


A measure reflecting a player's capacity to exert force. It strongly correlates with 10-meter momentum times and shows a moderately strong association with dominant collisions.



CMJ - Relative Peak Power (Watts/Kg)


An index indicating a player's ability to generate force in proportion to their body mass. It exhibits a moderate relationship with 10-meter times.



CMJ - Jump Height (cm)


An assessment of overall athleticism, jump proficiency, and coordination. It can serve as an indicator of elastic capabilities.



CMJ - RSI Mod (m/s)


Takes into account both the height and speed of a jump. A high RSI mod score is linked to an efficient stretch-shortening cycle (SSC) and well-developed elastic/stiffness properties.



Repeated Hop - Bilateral RSI


It is calculated by the ratio of jump height to contact time and reflects how an athlete can utilize elastic energy and maintain stiffness at the ankle during consecutive hops. A higher bilateral RSI is associated with a more efficient SSC and better elastic qualities transferring to sprint performance



Speed


Speed scores are shown as times in seconds from 0-40m. Flying 10m is the final split of a 40m sprint, which is the amount of time taken to cover 30-40m and is an indicator of maximal sprint speed. Momentum is linked to dominant carries and collisions. Momentum calculation: 10m average speed (m/s) x body mass (kg).
