“…In the early stance phase, the ground reaction force and muscle activity around the thigh become active, and it is thought that large deformation of the skin around the knee is caused by muscle contraction around the thigh. The lateral and medial epicondyles were expected to be particularly affected by muscle contraction around the thigh, and Ishii et al [19] reported that the medial epicondyle had the largest error compared with the error between the skin marker sets and the PCT. In this study, the lateral and medial epicondyles showed high correlations of >0.90.…”

Objective. There are no reports comparing the protocols provided by rigid marker set (RMS) and point cluster technique (PCT), which are similar in terms of estimating anatomical landmarks based on markers attached to a segment. The purpose of this study was to clarify the correlation of the two different protocols, which are protocols for knee motion in gait, and identify whether measurement errors arose at particular periods during the stance phase. Methods. The study subjects were 10 healthy adults. All estimated anatomical landmarks were which their positions, calculated by each protocol of the PCT and RMS, were compared using Pearson's product correlation coefficients. To examine the reliability of the angle changes of the knee joint measured by RMS and the PCT, the coefficient of multiple correlations (CMCs) was used. Results. Although the estimates of the anatomical landmarks showed high correlations of >0.90 (P < 0.01) for the Y- and Z-coordinates, the correlations were low for the X-coordinates at all anatomical landmarks. The CMC was 0.94 for flexion/extension, 0.74 for abduction/adduction, and 0.71 for external/internal rotation. Conclusion. Flexion/extension and abduction/adduction of the knee by two different protocols had comparatively little error and good reliability after 30% of the stance phase.

“…In this study, a point cluster technique (PCT) that outputs the in vivo 6DOF rotational and translational displacements of the tibiofemoral joint was used to collect the 3D kinematic data 23,24 . The PCT has been used to estimate ACL strain 25 , identify the kinematic risk factors for ACL injury, 19,20 compare the rotational stability between single-and double-bundle ACL reconstructions 26 , and calculate the knee joint moment 27 . Among the 6DOF data, the present study examined the valgus/varus, external/internal rotation, and anterior/posterior translation that were discussed in a relevant previous study 5 .…”

“… Buchheit et al (2011) reported that there was no significant difference in VO 2 per meter between different speeds (45, 60, and 75% of maximal aerobic speed), whereas Stevens et al (2015) and Zago et al (2018) claimed that it would be significantly higher when the speed increased. However, researchers mainly focused on forward running, which has been widely studied in either the physiological demands or the acute biomechanical determinants ( Ishii et al, 2011 ; Zamparo et al, 2015 ; Zago et al, 2019 , 2021 ). Although forward running has received much attention, other directional modes of shuttle running have been less concerned.…”

PurposeThe aim of this study was to investigate the physiological and perceptional responses to forward, forward-backward, and lateral shuttle running.MethodsTwenty-four eligible male subjects performed a maximal oxygen uptake (VO2max) test and three directional modes (i.e., forward, forward-backward, and lateral) of 5-m shuttle running at the speed of 6 km⋅h–1 for 5 min on separate days. Heart rate (HR) and oxygen uptake (VO2) were continuously measured during the whole tests. Rating of perceived exertion (RPE) was inquired and recorded immediately after the test. Capillary blood samples were collected from the earlobe during the recovery to determine the peak value of blood lactate concentration ([La–]peak).ResultsRunning directional mode had significant effects on HR (F = 72.761, P < 0.001, η2p = 0.760), %HRmax (F = 75.896, P < 0.001, η2p = 0.767), VO2 (F = 110.320, P < 0.001, η2p = 0.827), %VO2max (F = 108.883, P < 0.001, η2p = 0.826), [La–]peak (F = 55.529, P < 0.001, η2p = 0.707), and RPE (F = 26.268, P < 0.001, η2p = 0.533). All variables were significantly different between conditions (P ≤ 0.026), with the variables highest in lateral shuttle running and lowest in forward shuttle running. The effect sizes indicated large magnitude in the differences of all variables between conditions (ES = 0.86–2.83, large) except the difference of RPE between forward and forward-backward shuttle running (ES = 0.62, moderate).ConclusionThese findings suggest that the physiological and perceptional responses in shuttle running at the same speed depend on the directional mode, with the responses highest in lateral shuttle running, and lowest in forward shuttle running.
