“…Standardized neutral running shoes (Nike Air Pegasus 34) were provided (Nike, Beaverton, OR, USA). Afterwards, they were required to run at 3.33 m/s [25] until they could not continue running [26]. They were considered to have experienced fatigue, and intervention was terminated when both following criteria were met: (1) the HR of the participants reached 90% of their age-calculated maximum HR, and (2) the participants could not continue running.…”

Purpose: This study aimed to determine the changes in lower extremity biomechanics during running-induced fatigue intervention. Methods: Fourteen male recreational runners were required to run at 3.33 m/s until they could no longer continue running. Ground reaction forces (GRFs) and marker trajectories were recorded intermittently every 2 min to quantify the impact forces and the lower extremity kinematics and kinetics during the fatiguing run. Blood lactate concentration (BLa) was also collected before and after running. Results: In comparison with the beginning of the run duration, (1) BLa significantly increased immediately after running, 4 min after running, and 9 min after running; (2) no changes were observed in vertical/anterior-posterior GRF and loading rates; (3) the hip joint range of motion (θ ROM ) significantly increased at 33%, 67%, and 100% of the run duration, whereas θ ROM of the knee joint significantly increased at 67%; (4) no changes were observed in ankle joint kinematics and peak joint moment at the ankle, knee, and hip; and (5) vertical and ankle stiffness decreased at 67% and 100% of the run duration. Conclusion: GRF characteristics did not vary significantly throughout the fatiguing run. However, nonlinear adaptations in lower extremity kinematics and kinetics were observed. In particular, a "soft landing" strategy, achieved by an increased θ ROM at the hip and knee joints and a decreased vertical and ankle stiffness, was initiated from the mid-stage of a fatiguing run to potentially maintain similar impact forces.

“…In their study on the kinematic parameters of fatigue caused by running on a treadmill, Koblbauer et al showed that after fatigue (caused by running on a treadmill), the inversion-eversion and supination-pronation did not change, and the pattern was the same as before-fatigue conditions [17]. Christina et al (2001) in their study also showed that the leg eversion of the ground exercise-induced fatigue did not change [25].…”

This study aimed to compare the effects of fatigue due to overground and treadmill running on the plantar pressure distribution pattern. Methods: Twelve novice athletes (Mean±SD age=26.0±2.5 y, Mean±SD weight: 52.0±3.0 kg, Mean±SD height: 159.0±5.0 cm), without sports injuries over the past year, were selected. Overground and treadmill running created fatigue in the samples. Peak plantar pressure distribution, Center of Pressure, contact area, and impulse the samples were recorded using a footscan (Footscan Version 7 Gait 2 nd generation software) pressure system during running before and after the fatigue protocol and analyzed with repeated measures ANOVA in SPSS v. 18. Results: Peak plantar pressure on the second to fifth toe , the fourth and fifth metatarsal bones, and medial part of the heel significantly increased. The shift in the Center of Pressure of the foot was non-significant in all stages. The contact area at the second metatarsal and midfoot area shifted only before the fatigue protocol on overground running. Impulse at the second to fifth toe, first to fifth metatarsal, significantly increased in the ground running. Conclusion: The results showed that fatigue due to treadmill running has different effects compared to fatigue due to overground running.

Studies show that the human nervous system is able to parameterize gait cycle phase using sensory feedback. In the field of bipedal robots, the concept of a phase variable has been successfully used to mimic this behavior by parameterizing the gait cycle in a time-independent manner. This approach has been applied to control a powered transfemoral prosthetic leg, but the proposed phase variable was limited to the stance period of the prosthesis only. In order to achieve a more robust controller, we attempt to find a new phase variable that fully parameterizes the gait cycle of a prosthetic leg. The angle with respect to a global reference frame at the hip is able to monotonically parameterize both the stance and swing periods of the gait cycle. This survey looks at multiple phase variable candidates involving the hip angle with respect to a global reference frame across multiple tasks including level-ground walking, running, and stair negotiation. In particular, we propose a novel phase variable candidate that monotonically parameterizes the whole gait cycle across all tasks, and does so particularly well across level-ground walking. In addition to furthering the design of robust robotic prosthetic leg controllers, this survey could help neuroscientists and physicians study human locomotion across tasks from a time-independent perspective.
