|---|---|---|---|---|---|---|---|---|
| [62] | SF ↑ 7.5% | ↑ 8.6%; R: 8.5% | ↓: 9% *; R: 6.2% |
kinematics: ↓Foot at FStrike: 22%, R: 19% ↓ Tibia at Fstrike: 31%; R 35% |
kinematics: ↑ Flex at Fstrike: 25%; R 32%. kinetics: CKF: ↓ 7.6–10.61% R: 4.5–8.24%. |
Step length: ↓ 8.36%; R: 8.2% | * COP distance from body COM at FStrike | |
| [72] | SF ↑ 7.5% | ↑ 8.6%; R ↑ 8.5% |
kinetics: VALR; 19%; R: 20%; VILR: 18%; R: 17.5% |
kinetics: Abs↓ 27.27% R: ↓ 21.21%; Abs/km ↓ 21.1%, R: ↓ 14% |

| [75] | SF ↑ 10% and loading FS | ↑ 10% | COP foot position: Moved forward SF: 6%; SF and Visual FB: 37.31%; SF and Auditory FB: 45.35% Combined: 45.51% |
kinetics: Area loaded: midfoot ↓ 40%, heel ↓ 80%, forefoot ↑ 10–36%; great toe ↑ 30% |

| [74] | SF (↑ 10%, 20%, ↓ 10%, ↓ 20) & head trajectory |
↑ 10–20% | kinetics: Tibia shock attenuation: SF + 20 = ↑ 12%; SF + 10 = ↑ 5% peak impact acceleration ↓ 1.9% |
Significant changes across all SF conditions. Larger impact on Tibia with SF-20. Changes reported in this table: +20, +10. Feedback was not significantly correlated with variables. | ||||
| [76] | SF ↓ 0–10%; VD: ↓ 10–20% and P ↓ 10–20% |
↑ up 7% and ↓ 10% * | ↓ 20% and ↑ 5% * | Trend value. Not significant |
Definitions: Decreased (↓), increased (↑), foot strike (FStrike); absorption (Abs); adduction (add); 1-month retention (R); run power (P); step frequency (SF); feedback (FB). (*) details about a value in comments.
