Figure 1. Relationship between HF (s²/Hz) and Performance (% best national Performance).

Representation for four female (S2, S4, S5, S6) and six male subjects (S1, S3, S7, S8, S9, S10). Best performances were: Female: 1.42 m.s⁻¹ (S2), 1.32 m.s⁻¹ (S4), 1.18 m.s⁻¹ (S5) and 1.47 m.s⁻¹ (S6); and Male: 1.51 m.s⁻¹ (S1), 1.39 m.s⁻¹ (S3), 1.64 m.s⁻¹ (S7), 1.47 m.s⁻¹ (S8), 1.45 m.s⁻¹ (S9) and 1.41 m.s⁻¹ (S10).
