Meng C, Walts C, Ryan L, Stearne D, Clark K
Sports Biomech
. 2024 Nov;
:1-14.
PMID: 39492756
We investigated spatiotemporal kinematics during top speed sprinting and biomechanical running strategies in 98 male intercollegiate athletes from a range of athletic backgrounds in track and field (TF, = 28)...

Hum Mov Sci
. 2024 Sep;
98:103280.
PMID: 39299173
Sprinting at maximum velocity requires fast angular motion of the thigh and effective hamstring function for optimum performance and injury prevention. In this cross-sectional investigation of 21 male sprinters, we...

J Hum Kinet
. 2023 May;
87:1-9.
PMID: 37229404
Horizontal foot speed is fundamental for running synchronization and stability, and may also be important for sprinting performance. In this investigation, we quantified the following during steady-speed running: (a) peak...

Front Sports Act Living
. 2022 Jul;
4:945688.
PMID: 35903404
Sprinting performance is critical for a variety of sports and competitive activities. Prior research has demonstrated correlations between the limits of initial acceleration and maximum velocity for athletes of different...

Clark K, Ryan L, Meng C, Stearne D
Sports Biomech
. 2021 Oct;
23(11):1963-1976.
PMID: 34678124
The hip joint and surrounding musculature must generate and withstand torque during the swing phase of running. Prior research has demonstrated that sagittal plane hip torque increases with speed, indicating...

Udofa A, Clark K, Ryan L, Weyand P
J Appl Physiol (1985)
. 2019 Feb;
126(5):1315-1325.
PMID: 30763160
Although running shoes alter foot-ground reaction forces, particularly during impact, how they do so is incompletely understood. Here, we hypothesized that footwear effects on running ground reaction force-time patterns can...

PM R
. 2019 Feb;
11(11):1184-1192.
PMID: 30729729
Background: Although postural control deficits are common following a concussion, the current clinical assessments for postural control tend to resolve within 3 to 10 days after injury. There is a...

J Exp Biol
. 2016 Nov;
220(Pt 2):247-258.
PMID: 27811299
The relationship between gait mechanics and running ground reaction forces is widely regarded as complex. This viewpoint has evolved primarily via efforts to explain the rising edge of vertical force-time...

Med Eng Phys
. 2015 Jul;
37(9):892-7.
PMID: 26143150
Investigations focused on the gait and physiological limits of human speed have been on-going for more than a century. However, due to measurement limitation a kinetic understanding of the foot-ground...

J Exp Biol
. 2014 Apr;
217(Pt 12):2037-40.
PMID: 24737756
Running performance, energy requirements and musculoskeletal stresses are directly related to the action-reaction forces between the limb and the ground. For human runners, the force-time patterns from individual footfalls can...
