Method isn't having every tool. It's knowing which one to use, when, and why.
Nex Performance starts where the client is, uses what the client has, and builds what's missing — with tools validated by scientific literature and applicable to any budget.
The four principles
Evidence before opinion
Every methodological decision is grounded in scientific literature and client data. We don't use protocols because they're popular — we use them because they work and we know why. When evidence isn't sufficient, we say so.
Adaptation to the client's context
Every club starts somewhere different. One with no budget begins with RPE in Google Forms; another already has GPS and a heart-rate monitor and just needs someone to read what they've been collecting for years. The destination is the same: data that guides training. Only the path differs.
Client autonomy as the end goal
Good consulting doesn't create dependency. We empower the technical staff to operate the implemented systems autonomously. After 36 months, the club can renew the partnership or operate without us.
Honesty about what is and isn't possible
We say what we know how to do and what we don't. We say when a tool is enough and when it needs an upgrade. We say if an athlete's data doesn't allow a clear conclusion. Honesty isn't weakness — it's a prerequisite for the client to trust the next 12 months.
The four base tools
Accessible technical explanation of each tool.
RPE — Rating of Perceived Exertion
Borg's CR-10 scale, applied within 30 minutes after each session. Multiplied by session duration in minutes, it generates Arbitrary Units of internal load. Method validated by Foster et al. (2001) and Impellizzeri et al. (2004), adopted by top professional clubs precisely for its simplicity and reliability.
GPS — Global Positioning Systems
External load monitoring technology that records total distance, meters per minute, accelerations, decelerations and peak speed during training and matches. This data quantifies the athlete's real effort and supports load management, training prescription and injury prevention (Aughey, 2011; Cummins et al., 2013).
Wellness questionnaires
Daily or pre-session evaluation of five indicators: sleep quality, fatigue, stress, muscle soreness and mood. 60-second completion. Cross-referenced with training loads, it anticipates overload episodes before they become injury.
Physical testing batteries
Standardised protocols adapted by sport: linear speed, agility, maximum strength, explosive strength (CMJ, SJ), aerobic endurance, flexibility. Applied two to three times per season to measure objective evolution and guide plan adjustments.
