Racquet Sports S&C — all lessons

Multi-directional load and movement analysis

Analysing multi-directional loads in racquet sports — accelerations, decelerations, lunges and jumps — and their implications for injury and training.

Advanced Evidence: Emerging evidence 3 min read Reviewed 2026-10-31 Status: draft

Learning objectives

  • Quantify multidirectional movement demands
  • Relate loads to injury patterns
  • Use video and wearables for analysis
  • Translate analysis into training

Before this lesson

Why this matters

Understanding load patterns explains common injuries and guides training.

Demands

Frequent short sprints, decelerations, direction changes, lunges and jumps; match intensity is intermittent [fernandez2006].

Injury patterns (tennis)

Lower-limb acute injuries (ankle, knee, thigh) and upper-limb overuse (shoulder, elbow) [pluim2006].

Analysis tools

Video coding of movements; IMUs and stroke sensors [cardinale2017].

Training implications

Eccentric strength, deceleration drills, landing mechanics, shoulder and forearm capacity.

Common mistakes and misconceptions

Case study

A squash coach codes 3 matches and finds ~10 deep lunges per minute of play. Eccentric strength work and lunge-specific conditioning are added.
