PURPOSE Knowledge regarding the biomechanical function of the lower limb muscle groups across a range of running speeds is important in improving the existing understanding of human high performance as well as in aiding in the identification of factors that might be related to injury. The purpose of this study was to evaluate the effect of running speed on lower limb joint kinetics. METHODS Kinematic and ground reaction force data were collected from eight participants (five males and three…

Linear and non-linear analysis of lower limb joints angle variability during running at different speeds
Background: Stability is one of the key demands in human locomotion including running. Various kinematical analytical approaches are adopted to investigate the running strategies; nevertheless, the
Hip muscle loads during running at various step rates.
TLDR
Increasing running step rate for a given running speed heightened hamstring and gluteal muscle loading in late swing, while decreasing stance-phase loading in the glutesal muscles and piriformis.
A biomechanical study of side steps at different distances.
TLDR
The main roles of hip abduction torque and work were to accelerate the center of mass laterally in the earlier phase of the movement and to keep the trunk upright, but not to generate large power for propulsion.
Lower-limb muscular strategies for increasing running speed.
TLDR
Basic science knowledge regarding lower-limb muscle function during running has implications for understanding why sprinting performance declines with age and is of great value for designing rehabilitation programs to restore running ability in young, previously active adults who have sustained a traumatic brain injury.
Biomechanics of graded running: Part II—Joint kinematics and kinetics
TLDR
It is demonstrated that ankle, knee, and hip joint kinetics depend on speed and grade of running, while the effect of grade on joint kinematics was not substantially modulated by speed.
Determination of loading strategies during landing in badminton
TLDR
The results obtained in this experiment revealed the highest loading to the motor system in the areas of knee joints during backhand and in the ankle joint during smash, which was unable to isolate the joint loading strategies during performance of individual elements of badminton playing technique.
Three-dimensional CoM energetics, pelvis and lower limbs joint kinematics of uphill treadmill running at high speed
TLDR
The results demonstrate that joint motion must be developed from a more flexed/adducted position at initial contact through a greater range of motion compared to level running in order to meet the greater positive CoM work requirements in uphill running at high speed.
Running into Fatigue: The Effects of Footwear on Kinematics, Kinetics, and Energetics.
TLDR
Irrespective of the shoe design, alterations in the running mechanics occurred in the first 2 km of the run, which might be attributed to the existence of a habituation rather than fatigue effect.
Modulation of work and power by the human lower-limb joints with increasing steady-state locomotion speed
TLDR
The results suggest that changing locomotion mode and faster steady-state running speeds are not simply achieved via proportional increases in work and average power at the lower-limb joints.

The investigation of the effects of speed related changes on joint moments may be an optimal method to study injury mechanisms indirectly and to identify accommodation strategies to the varied impact
Moment and power of lower limb joints in running.
TLDR
The results may suggest that the role of the ankle and knee extensor is to create high joint stiffness before and during the contact phase, while the hip extensors are the prime forward movers of the body with increasing running speed.
Stance phase knee and ankle kinematics and kinetics during level and downhill running.
TLDR
The results suggest that muscle soreness during DR may be related to high peak power absorption values since the peak joint extensor moments are similar between conditions.

TLDR
These data suggest that compared with LSSF and LSS, INC provides enhanced muscular loading of key mono- and bi-articular muscles during both swing and stance phases.
Lower-limb mechanics during the support phase of maximum-velocity sprint running.
TLDR
The knee moment did not contribute substantially to power generation during the latter part of the support phase of a maximum-velocity sprint, however, major periods of power generation of the hip extensors in early stance and of the plantar flexors in late stance were observed.

TLDR
Three-dimensional kinematic and ground reaction force data is collected on 20 recreational runners with normal rearfoot mechanics to provide important information regarding muscle function and may lend insight into the etiology of overuse injuries common to runners.
Knee and ankle joint stiffness in sprint running.
TLDR
In sprint running the spring-like behavior of the leg might be adjusted by changing the stiffness of the knee joint, which may depend on (constant) tendon stiffness because of its dominating role in triceps surae muscle-tendon unit.
Muscle power patterns in the mid-acceleration phase of sprinting
TLDR
The role of the knee appears to be one of maintaining the centre of mass height and enabling the power generated at the hip to be transferred to the ankle, with the plantar flexors producing the greatest peak power.
