Abstract The purpose of this study was to examine the overall kinetics and at joints lower limb while sprinting maximum speed, compare data a double transtibial amputee able‐bodied controls running same level performance. One amputee, using dedicated prostheses, five sprinters participated in study. athletes performed submaximal maximal sprints (60 m) on an indoor track. All participants ran three times each speed (maximal submaximal). athletes' kinematics were recorded Vicon 624 system with...
Enhancement of activity is one major topic related to the ageing society. Therefore, it necessary understand people's motion and identify possible risk factors during activity. Technology can be used monitor patterns daily life. Especially use artificial intelligence combined with wearable sensors simplify measurement systems might at some point replace standard capturing using optical technologies. this study aims analyse estimation 3D joint angles moments lower limbs based on IMU data a...
Longitudinal midsole bending stiffness and elasticity are two critical features in the construction of running shoes. Stiff elastic materials (eg, carbon fiber) can be used to alter behavior. The purpose this study was investigate effects manipulation on metatarsophalangeal (MTP) joint mechanics during 19 male subjects at 3.5 m/s. Midsole were modified by means fiber insoles varying thickness. Stiffening shoe structures around MTP caused a shift point force application toward front edge...
The application of artificial intelligence techniques to wearable sensor data may facilitate accurate analysis outside controlled laboratory settings—the holy grail for gait clinicians and sports scientists looking bridge the lab field divide. Using these techniques, parameters that are difficult directly measure in-the-wild, be predicted using surrogate lower resolution inputs. One example is prediction joint kinematics kinetics based on inputs from inertial measurement unit (IMU) sensors....

In Paralympic sports, athletes often depend on some form of equipment to enable activities daily living, including the ability participate in sport. Determining precisely when technology assists sports performance and it transforms or distorts them presents a philosophical ethical dilemma. We raise conceptual problem line-drawing between promoting rights access that provide equal opportunity while proscribing ‘boosting’ where with disability are afforded an unfair advantage. set out...
Curve running requires the generation of centripetal force altering movement pattern in comparison to straight path run. The question arises which kinematic modulations emerge while bend sprinting at high velocities. It has been suggested that during curve sprints legs fulfil different functions. A three-dimensional motion analysis (16 high-speed cameras) was conducted compare segmental kinematics lower extremity stance phases linear and (radius: 36.5 m) six sprinters national competitive...
The purpose of this study was to explore the relationship between forces applied starting blocks and start performances (SPs) amputee sprinters (ASs) non-amputee (NASs). SPs 154 male female NASs (100-m personal records [PRs], 9.58–14.00 s) 7 ASs (3 unilateral above knee, 3 below 1 bilateral knee; 100 m PRs, 11.70–12.70 with running specific prostheses (RSPs) were analysed during full-effort sprint starts using instrumented that measured in 3D. Using NAS dataset a combination factor analysis...
For human locomotion, varying environments require adjustments of the motor system. We asked whether age affects gait balance recovery adaptation, its retention over months, and transfer adaptation to an untrained reactive task. Healthy adults (26 young, 27 middle-aged, 25 older; average ages 24, 52, 72 yr, respectively) completed two tasks. The primary task involved treadmill walking: either unperturbed (control; n = 39) or subject unexpected trip perturbations (training; 39). A single...
The purpose of this work was to provide a fundamental, in-depth analysis kinematics and kinetics the bobsleigh push phase establish basis for performance enhancement. Fifteen elite male athletes performed maximal effort starts, while ground reaction forces (GRF) 3D marker trajectories were simultaneously recorded contacts different sub-sections (start acceleration phase: first second contact after initial push-off from start block, 10 m high-velocity 30 m). To obtain comprehensive view...
Knee osteoarthritis (KOA) impairs mobility, particularly in higher demanding tasks like stair climbing and slope walking. While unloader braces are well-studied for level walking (LVL), their effects on more complex locomotion remain underexplored. This study analyzes how influence knee joint kinetics load distribution over various tasks. Twenty participants with medial KOA were assessed at baseline (BAS) after six weeks (FU) of using a valgus brace. Musculoskeletal modeling was used...
Abstract Background Providing runners with injury prevention suggestions from a biomechanical perspective is crucial in light of the increased incidence running-related injuries forecasted rising popularity half-marathon. Previous research has demonstrated associations between running and patterns lower extremity biomechanics, as well indicating that inadequate rest training sessions can result underperformance. However, whether half-marathon elicits changes recovery time remains largely...
The increasing participation in running events, particularly half-marathons, has been noteworthy recent decades. However, the time course of recovery muscle performance after a half-marathon remains largely unclear. This study aimed to investigate changes concentric and eccentric quadriceps hamstring peak torques mean powers, as well torque power ratios, half-marathon. Thirty-eight recreational runners participated this study. Isokinetic dynamometry was used measure at four points: pre...
