Effects of Two Fatigue Protocols on Impact Forces and Lower Extremity Kinematics during Drop Landings: Implications for Noncontact Anterior Cruciate Ligament Injury

Table 1

Comparison of intervention effects for constant speed running fatigue protocol (R-FP) and shuttle running + vertical jumping fatigue protocol (SV-FP).

Variables	R-FP	SV-FP
Duration time/s	1126.5 ± 344.6	257.8 ± 59.3
Maximal HR/min	189.4 ± 6.9	184.7 ± 6.3
RPE	16.3 ± 1.3	16.7 ± 1.4

Significantly different from R-FP with .
