, 12 this functional aspect needs to be addressed. Sprinting is a common mechanism of injury when the hamstrings work eccentrically in a stretched position. 1 , 11 , 12 Such movements can be seen during the terminal swing, specifically the late swing and early stance phase of running while sprinting

High-Load Squat Training Improves Sprinting Performance in Junior Elite-Level Soccer Players: A Critically Appraised Topic
Lars H. Lohmann, Konstantin Warneke, Stephan Schiemann, and Irene R. Faber
Soccer is an intermittent sport in which high- and low-intensity actions alternate 1 while the most crucial events during matches in modern soccer are high-intensity actions. 2 These actions are primarily high-intensity running (HIR) bouts also referred to as sprinting. 2 , 3 Though the majority
Sprinters Report Poorer Medial Tibial Stress Syndrome Outcomes Compared With Endurance Runners Over the Course of a Competitive Track Season
Leah M. Balsamo, Kenneth P. Clark, Katherine E. Morrison, and Nicole M. Cattano
Key Points ▸ Medial tibial stress syndrome (MTSS) is one of the most common overuse injuries in runners. ▸ Little research has been done on sprinters and MTSS. ▸ Sprinters scored significantly worse on MTSS patient-reported outcome measures than their endurance (ED) teammates. ▸ Patient
Do Lower-Limb Kinematic and Kinetic Asymmetries Transfer Across Sprint Running and Countermovement Jumps in University Rugby Union Players?
Lewis J. Vizard, Gareth Peden, and Maximilian M. Wdowski
Key Points ▸ Lower-limb kinematic and kinetic asymmetries may transfer between dynamic movements. ▸ Individual-level asymmetries present in lower-limb kinematics and kinetics during sprint running and countermovement jumps. Rugby Union is an intermittent contact sport that exposes players to short

Decreases in Performance Observed After COVID-19 Infection in High School Female Soccer Players
Andrew Wilson, Lynette M. Carlson, Colton Norton, and W. David Bruce
Key Points ▸ Female high school soccer sprint performance decreased after COVID-19 infection. ▸ COVID− group increased sprint distances 8.43% versus COVID+ group’s decrease of 21.13%. ▸ Female high school soccer players decrease total distance run per game after COVID-19. In late 2019, the novel
Assessment of Kinematic Asymmetry for Reduction of Hamstring Injury Risk
Simone Ciacci, Rocco Di Michele, Silvia Fantozzi, and Franco Merni
Context:
Kinematic asymmetry is believed to be associated with elevated risk for muscle injury, but little is known about the links between hamstring injuries and asymmetry of sprinting mechanics.
Objective:
To evaluate the value of kinematic analysis of sprinting for the detection of injury-related asymmetry in athletes with a history of hamstring strain.
Participants:
Six sub-elite male sprinters, including two who sustained a hamstring strain injury.
Outcome Measures:
Absolute differences between left and right symmetry indices and symmetry angles were both calculated for ground contact time and selected angular displacements. Measurements were acquired at foot strike, during the stance phase, and at toe-off.
Results:
At toe-off, injured athletes exhibited greater knee flexion and less hip extension for the injured extremity compared to the uninjured extremity. Symmetry indices for these variables markedly exceeded an established 15% threshold for clinically relevant asymmetry. Each of the uninjured athletes exhibited a high degree of symmetry for all parameters, with mean values for symmetry indices significantly lower than the 15% threshold (P < 0.05).
Conclusions:
Kinematic analysis of sprinting asymmetry appears to be valuable for identification of elevated risk for hamstring injury.
Effect of Cardiovascular Fatigue on Postural Stability
Hamid Bateni, Gina Leno, Rebeca Manjarres, Bailey Ouellette, and Mark Wolber
Context:
Previous research has demonstrated that localized leg muscle fatigue induced by lower extremity exercises (e.g., squat jumps, sprints, and treadmill running) has an adverse effect on postural stability.
Objective:
To assess the effect of cardiovascular fatigue induced by upper extremity exercise on postural stability.
Design:
Repeated measures.
Participants:
Fourteen healthy young adults between the ages of 22 and 30 years (7 male and 7 female).
Intervention:
Participants performed an exercise protocol on an upper-body ergometer to induce cardiovascular fatigue.
Main Outcome Measures:
Postural sway, represented by center of pressure excursion, during bilateral standing in two different foot positions.
Results:
In a tandem standing position, mediolateral mean distance, root mean square distance, resultant power, and centroidal frequency increased signifcantly after inducement of cardiovascular fatigue.
Conclusion:
Cardiovascular fatigue adversely affects postural stability.
