029 Does acute fatigue negatively affect the lower extremity injury risk profile? A systematic and critical review

Research output: Chapter in Book/Report/Conference proceedingMeeting abstract (Book)

Abstract

Background Acute fatigue is hypothesized to alter injury risk
profiles by affecting intrinsic risk factors (i.e. postural control,
hamstring strength). However, no systematic overview exists
that merges the insights of prospective lower extremity injury
risk profiling with the effect of acute fatigue on functional
test performance.
Objective The objective of this review was to identify the
influence of acute fatigue on prospectively determined modifiable
intrinsic risk factors for lower extremity injuries and to
determine if individual fatigue outcomes should be integrated
within an athlete centred injury risk profile and prevention
strategies.
Design Systematic review
Methods PubMed (MEDLINE), Web of Science, PEDro, and
Cochrane Library were searched until 29 May 2019. Studies
were eligible when the study outcomes encompassed intrinsic
modifiable risk factors, an acute fatigue intervention, and
included healthy athletes or physically active people. Intrinsic
modifiable risk factors were identified through recent systematic
reviews and meta-analyses. Referenced original research
papers were used to determine outcome measures associated
with increased injury risk.
Main Outcome Measurements Acute fatigue effect on the
intrinsic modifiable risk factors for lower extremity injuries.
Results Forty studies reported acute fatigue effects on modifiable
risk factors, with eight studies matching all criteria for
data-extraction. Acute fatigue can decrease single leg postural
control, decrease ankle joint position sense, decrease isokinetic
strength of hamstring and quadriceps muscles and can affect
isokinetic H:Q ratios.
Conclusions Acute fatigue affects prospective intrinsic modifiable
risk factors, indicating an altered injury risk profile for
lateral ankle sprain, patellofemoral pain syndrome and hamstring
injuries when fatigued. Current data does not allow
conclusions for non-contact ACL injury risk. Clinicians
should consider acute fatigue responses as part of injury risk
profiling strategies. Future research should allow for individual
fatigability as a relevant injury risk outcome and merge
insights from athlete centred injury risk profiling and fatigue
research.
