Summary: The study found that different walking environments significantly affect gait performance, with treadmill walking resulting in slower gait with shorter, less variable strides, and outdoor walking resulting in faster gait with longer strides. The effects of walking condition on gait measures were more significant than participant age.

Summary: The study found that age does not affect the net metabolic cost of overground walking, but older adults may have a higher net metabolic cost of walking on a treadmill compared to overground walking at their preferred speed, which may require a longer adaptation period.

Summary: As individuals age, there is a decline in gait automaticity, which leads to increased attentional resources during walking. This study aims to investigate the effect of treadmill walking on prefrontal cortex (PFC) activation and dual-task performance in older adults. The results show that dual-task treadmill walking leads to reduced PFC activation and improved dual-task performance compared to dual-task overground walking. This suggests that walking on a treadmill may help older adults maintain similar levels of dual-task performance as younger adults with less cognitive effort.

Summary: Gait speed declines with age, and this study investigates the reasons why older adults do not walk faster despite being capable. The research utilizes functional near infrared spectroscopy to monitor changes in regional oxygenated hemoglobin (HbO2) in the frontal lobe while participants walk at preferred and fast speeds. The results suggest that walking fast requires increased activation of motor regions in older adults, highlighting the importance of this study for rehabilitation purposes.

Summary: This study examines the effects of front load carriage on dynamic gait stability, step length, and trunk angle among young adults during treadmill walking. The findings suggest that carrying a front load significantly alters trunk orientation and may impact the kinematic relationship between the body's center of mass and base of support, thus increasing fall risk.

Summary: This study explored the impact of walking state, self-reported daily walking amount, and age on gait quality among older adults using a smartphone application. The results showed that gait quality was better during fast walking compared to normal walking, and simulated visually impaired walking had no significant effect on gait quality. Older individuals had a decline in gait quality compared to relatively younger older adults, and older adults who walked more than 1 km a day had better gait quality.

Summary: Older adults exhibit poorer mediolateral balance control compared to younger adults during walking, as indicated by a significantly higher range of frontal-plane angular momentum. This difference is attributed to wider foot placement and higher hip abduction moment in older adults, emphasizing the importance of proper weight transfer mechanisms and hip abductor force production for maintaining mediolateral balance.

Summary: This study analyzed the relationship between cortical activity and walking speed in elderly adults. The results showed that individuals with a slower preferred walking speed required a higher increase in cortical activity. Individuals in the fast cluster presented greater changes in cortical activation in the right hemisphere. This study demonstrates the importance of cortical activity in relation to walking speed and suggests that age may not be the most relevant factor.

Summary: This study analyzes the gait differences caused by the physical factors of treadmill walking. The results show that the lower-limb joint kinematics are the same under ideal treadmill conditions, regardless of body mass and walking speed. However, kinematic differences are observed under non-ideal treadmill conditions.

Summary: This study investigated the gait stability and variability measures in barefoot and shod locomotion in younger and older adults. The results showed that footwear and outdoor conditions had different effects on gait stability and variability parameters, indicating high adaptiveness of these parameters to experimental conditions. The findings highlight the clinical potential of barefoot walking.

Summary: This study investigated the influence of aging on PFC activity during overground walking at preferred and fast speeds. Older adults showed higher PFC activity than young adults in both conditions, with speed-related changes in PFC activity observed for older adults but not for young adults. The findings suggest that older adults recruit additional prefrontal cognitive resources to control walking, indicating a compensatory mechanism, and the left PFC seems to be involved in the modulation of gait speed in older adults.

Summary: Two different modes of step-to-step transition have been observed in older adults, with the impact on gait kinetics and kinematics not yet investigated. It was found that age and transition mode have differences in intersegmental coordination and COM trajectory during walking. The timing of COM redirection is linked to kinematic and mechanic changes in gait and may be used as a quantitative assessment of age-related decline.

Summary: The study found that during the lockdown period, the majority of young football players had reduced football activity time, with more individual practice and less organized team play. Less than half of the participants engaged in football for 7 hours or more weekly, and about 20% practiced football for less than 1 hour per week. Age and geographical background were factors influencing the amount of physical activity and quality of life among youth.

Summary: Past investigations on instep kicking in soccer provided limited information on kinematics. This study aimed to analyze the effects of ball approach angle and foot dominance on the whole-body kinematics of soccer players performing instep kicks. The findings showed that ball approach angle and foot dominance significantly influenced various aspects of the kicking motion. Coaches should vary ball approach angles and foot used during kicking drills to enhance technical effectiveness.

Summary: The study evaluated changes in the donor-site of autologous vascularised free fibula flap during stair climbing and descent. The results showed that except for the side effect of hip flexion, other gait parameters remained relatively unchanged. This suggests that vascularised free fibula flap reconstruction has minimal functional limitations for patients during stair climbing and descent.

Summary: This study compared the dynamic gait function of individuals with Down Syndrome to healthy controls using the concept of the virtual pivot point (VPP). The results showed that individuals with Down Syndrome had an anteriorly located VPP compared to healthy controls, likely due to larger hip moments during the propulsive phase of stance. High R-2 values in individuals with Down Syndrome suggest a strong association between the VPP and dynamic stability during walking.

Summary: The study aimed to evaluate the evolution of technical performance indicators during football matches in the UEFA Champions League. Data from three elite teams over four seasons were analyzed, showing a significant increase in frequency and accuracy of most parameters towards the end of matches. Match location had a significant effect, with better performance for home teams. Differences were observed between group stage and knockout phase, indicating different team approaches. The study suggested significant differences between initial and final periods of games and confirmed the existence of home advantage.

Summary: This study analyzed the relationship between lower limb strength, power production, flexibility, and performance in alpine ski racers. The results showed that both age and sex influenced these physical qualities and their relationship, with males having higher jump scores but lower sit-and-reach scores than females. Assessing and considering these qualities and their relationship longitudinally, taking into account sex and growth, is important for training and testing purposes.

Summary: This study describes the mechanisms, situational patterns, and biomechanics of Achilles tendon rupture (ATR) injuries in professional male football players. The findings show that ATRs mostly occur during accelerations and are predominantly non-contact injuries. The most common situational patterns are forward acceleration from standing, cross-over cutting, and vertical jumping. The biomechanics involve multiplanar loading, mainly in the sagittal plane, of the injured Achilles tendon. A significant number of ATRs occur in the first 30 minutes of match time.
