“…Subject Number 1 (test 1c) and Number 4 present very similar traces of the knee angle, with only little deviations from τ ranging from 0.1 to 1.0, denoting a very repeatable knee biomechanics constant during the entire exercise. This result is consistent with those available in the literature for fatigue-inducing running exercises (e.g., Koblbauer et al, 2014, Tian et al, 2020, irrespective of the different exercise protocol. A detailed analysis performed for subject Number 3 and limited to the early stage of exercise (τ ≤ 0.30) shows that as the subject increases his speed from the warmup (τ ≈ 0.05) to the prescribed treadmill velocity (τ > 0.10) the biomechanics changes, even if the behaviour within the cycle is similar.…”

“…Such small variations seems to be compatible with subject's repeatability indicated with dashed lines. It is worth noting that, at the authors' knowledge, no studies focused onto the foot trajectory during running exercise are available in literature, where angle analysis is typically performed (e.g., Koblbauer et al, 2014, Tian et al, 2020. Attention is now turned to angular strategies.…”

“…It can be argued that the effect of fatigue is not clearly related to the ROM of the ankle and knee angles, with some authors stating that there is no substantial fatigue effect (e.g., Brown et al, 2014), and others claiming that either an increase (e.g., Chan-Roper et al, 2012) or a decrease (e.g., Mizrahi et al, 2010, Tian et al, 2020 in knee angle ROM occurs over time. The fatigue protocol and the measurement method adopted (with measurements taken during or after the fatigue test) deeply affect the results in the opinion of the authors of the present research.…”

Biomechanics and thermoregulation of human running are key aspects playing an important role in the training of professional athletes. In the case of a prolonged exercise, as occurs during the marathon race, the intensity and duration of the exercise (in concert with environmental conditions) can affect the thermoregulatory response and the running mechanics. The aim of this study is the design of a novel experiment able to simultaneously capture information concerning the biomechanics of lower limbs and the surface temperature map of the whole body during a prolonged running exercise on treadmill. Kinematics quantities, such as linear and angular displacement, velocity and acceleration of relevant body markers are recorded by a video system, while surface temperature evolution on time is detected by an infrared thermal camera. A group of five amateur athletes, with long experience in long-distance running competitions, was involved in this study. Results for the sample group, in terms of kinematic (displacements and angles) and thermal (local and total-body skin temperatures) quantities, revealed features related to individual response to the effort. Even though the relatively little number of athletes does not permit to infer general conclusions, the combined mechanical and thermal experiment is deemed to be a useful tool for the investigation of endurance running characteristics.

Background Knee injury is always a trouble for people in daily life. It not only threatens the career of an athlete but also affects a normal engineer through morning running. The injury of the knee joint is found to be directly related to the fatigue caused by excessive exercise. Methods An economical embedded system with a designed acceleration-weighted curve fitting method was developed to estimate and predict the knee fatigue state. Then the warning message and recommended lasting time were sent to users to avoid excessive exercise. 24 healthy volunteers were involved in the experiments to verify the effectiveness of the system compared to human perception. Results Only using human perception to prevent knee joint fatigue had a risk of failure while the designed wearable system could protect knee successfully. It was also found that the knee of female was more likely to be injured than the one of male in intense exercises and a high BMI value could influence the risk of knee injuries during sports. However, a short break in sports could significantly extend the healthy time for knee. Conclusions Early warning from the specially designed embedded system can successfully help people avoid knee joint fatigue and injuries during exercises, such as running, badminton, table tennis and basketball.

Purpose: A novel portable system has been used to evaluate spatial knee movement, but its accuracy and repeatability is not known. The aim of this study was to investigate the accuracy and repeatability of the measurement. Methods: Ten healthy participants were included, and the knee motion trajectory during walking were assessed. Six evaluations were conducted (three days by two raters) for each participant. The motion parameters at the key points and the range of motion were statistically analyzed. Intraclass correlation coefficients (ICC), standard error of the measurement (SEM), and the Bland–Altman method were used. Results: For intra-rater repeatability, 1) the ICC values range from 0.75 to 0.9 for rotations; and 0.64 to 0.96 for translations. Among the ICC values, 100% of rotations and 90% of translations were not less than 0.70; 2) among the SEM values, 100% of rotations were not more than 5°, while 73.3% of translations were less than 3 mm. For inter-rater repeatability, 1) the ICC values range from 0.68 to 0.99 for rotations; and 0.57 to 0.93 for translations. Among the ICC values, 95.6% of rotations and 82.2% of translations were not less than 0.70; 2) among the SEM values, 100% of rotations were not more than 5°, and 48.9% of translations were less than 3 mm. The Bland–Altman plots showed good agreement for intra- and inter- repeatability. Conclusions: The results indicated that the accuracy and repeatability of the measurement were acceptable, except for the inter-rater repeatability for translation. This may help researchers and physicians better interpret the measurement data.
