Athlete Monitoring: Periodisation to Performance
Thanks to Kate Maher for allowing me to share her performance monitoring data from the past year.
Over the past year, Kate’s Countermovement Jump (CMJ) improved from 30.2 cm to 49.9 cm, while RSI-mod increased from 0.24 to 0.74 m/s.
The CMJ is one component of our monitoring battery. Beyond jump height, its force–time characteristics reflect concentric force production, stretch-shortening cycle efficiency, eccentric absorption, and neuromuscular readiness. Alongside track performance, training load, and clinical observations, these measures help individualise programming for the athlete and the demands of the 200/400 m.
As coaches, it’s easy to focus on sessions. The key question is whether the athlete is adapting as intended.
Kate’s data clearly reflects periodisation and peaking. During the preparation phase, both CMJ and RSI-mod improved as physical qualities developed. As racing and PBs accumulated, both dipped slightly—an expected response to competition fatigue rather than a loss of fitness.
After a planned taper, CMJ (49.9 cm) and RSI-mod (0.74 m/s) returned to peak levels ahead of the World Athletics U20 Championships.
No test can predict race performance, but when monitoring aligns with the training process, it increases confidence that the athlete is prepared to perform.
Periodisation is not about chasing gym PRs—it’s about developing the right qualities, maintaining them across the season, and peaking when it matters most.
The work is done. The preparation is complete.
Good luck, Kate. 🇮🇪💚
