Background : The quantification of electromyographic activity using surface electrodes is inval-uable for understanding gait disorders in patients with central nervous system lesions. We propose to evaluate a commercially available low-cost compared reference partic-ipants stroke-related movement functional situations. Methods Three hemiparetic participants performed three tasks: two treadmill walks at different speeds and sit-to-stand test. vastus lateralis gastrocnemius medialis muscles...

Abstract The aim of the present study was to examine sensitivity several movement features during running exhaustion in a subject-specific setup adopting cross-sectional design and machine learning approach. Thirteen recreational runners, that systematically trained competed, performed an exhaustive protocol on instrumented treadmill. Respiratory data were collected establish second ventilatory threshold (VT2) order obtain reference point regarding gradual accumulation fatigue. A approach...

This study aimed to examine countermovement jump (CMJ) kinetic data using logistic regression, in order distinguish sports-related mechanical profiles. Eighty-one professional basketball and soccer athletes participated, each performing three CMJs on a force platform. Inferential parametric nonparametric statistics were performed explore group differences. Binary regression was used model the response variable (soccer or not soccer). Statistical significance (p < 0.05) reached for...

Force platforms are widely used in biomechanics to measure ground reaction forces (GRF) during various human movements. However, traditional force plates not easily outside a research lab. To overcome this issue, researchers and manufacturers developing low-cost portable that can be variety of settings, including outdoors.

Background: Handheld dynamometers are used for diagnosis and rehabilitation at several pathologies. Grip force is essential a person’s quality of life. Most not equipped with or training protocols, although the bibliography highlights this need. Objective: To compare validity reliability Jamar K-Force in patients shoulder impingement syndrome healthy people. Methods: Concurrent was assessed using known weights. Forty-four (44) 69 adults performed three maximum repetitions random order each...

Trunk frontal plane kinematics is the most sensitive parameter to fatigue. Practitioners should consider this finding during endurance training.Kinetics exhibit a stable linear increase in mean values but non-linear variance an exhaustive incremental treadmill run. This may affect training at submaximal fatigued state.Specific areas joint distributions of kinetics and running increased sensitivity predicting fatigue state.

This study examined whether analysing kinetic features of drop jumps (DJ) as one-dimensional biomechanical curves can reveal specific patterns that are consistent and cluster DJ performance. Hierarchical clustering analysis on from 40 cm data performed by 128 physically active male participants (23.0 ± 4.5 yrs, 1.84 0.07 m, 79.1 10.8 kg) was the derived time-normalised force, power vertical stiffness to unmask underlying explore dissimilarities identified subgroup (cluster) analysis. Results...

We explored the impact of running in severe intensity domain on mechanics and muscle oxygenation competitive runners by investigating relationship between mechanical deviations from typical stride characteristics oxygen saturation (SmO

The quantification of electromyographic activity using surface electrodes is invaluable for understanding gait disorders in patients with central nervous system lesions. We propose to evaluate a commercially available low-cost compared reference participants stroke-related movement functional situations.

The purpose of the study was to examine effect resisted sled sprints (RSS) on biomechanical parameters first steps short&#x0D; acceleration sprints. Five track and field athletes performed 10-m using semi-standing (SSS) 3-point (TPS) starting techniques. RSS condition conducted with a load 9.7% ± 0.3 body mass. Results 2 (start technique) × (loading) 3 (steps) revealed significant (p .05) were evident for flight time pulling force. In conclusion, regardless technique, should be controlled...
