Previous studies have demonstrated that an acute bout of static stretching may cause significant performance impairments. However, there are no studies investigating the effect of prolonged stretch training on stretch-induced decrements. It was hypothesized that individuals exhibiting a greater range of motion (ROM) in the correlation study or those who attained a greater ROM with flexibility t...

BACKGROUND As the older adult population increases, the potential functional and clinical burden of trunk muscle dysfunction may be significant. An evaluation of risk factors including the impact of the trunk muscles in terms of their temporal firing patterns, amplitudes of activation, and contribution to spinal stability is required. Therefore, the specific purpose of this study was to assess ...

Objective: This study aimed to investigate the development of target joint position sense (JPS) and force (FS) in young gymnasts at different age groups compare effect external load on sense. Material Methods: A total 38 were divided into three groups: 12-14, 15-17, 18 over groups. The maximum voluntary isometric contraction (MVIC) forces participants a 90-degree hip angle measured with an isok...

Background: Occupational footwear and a prolonged duration of walking have been previously reported to play role in maintaining postural stability. The purpose this paper was analyze the impact three types occupational footwear: steel-toed work boot (ST), tactical (TB), low-top shoe (LT) on unreported lower extremity muscle activity during stability tasks. Methods: Electromyography (EMG) measur...

PURPOSE This study aimed: i) to examine the relationship between the magnitude of cross-talk in mechanomyographic (MMG) signals generated by the extensor digitorum (ED), extensor carpi ulnaris (ECU), and flexor carpi ulnaris (FCU) muscles with the sub-maximal to maximal isometric grip force, and with the anthropometric parameters of the forearm, and ii) to quantify the distribution of the cross...

Individuals are continuously looking for faster, more efficient methods with which to develop physical fitness. This has led to the development of products and programs marketed towards increasing physical fitness in minimal time. The Shake Weight(®) (SW) has been advertised to increase muscular strength among other factors in less time than traditional weightlifting. The purpose of this study ...

AIM The aim of the present study was to analyse the effects of training performed on a rotating, motorised platform (the Huber/SpineForce device from LPG Systems, Valence, France) intended to improve, postural control and muscle function. SUBJECTS Twelve healthy adults (divided into a sedentary group and an active group) took part in a two-month training programme (involving three sessions a ...

BACKGROUND Core stabilization has been utilized for rehabilitation and prevention of lower limb musculoskeletal injuries. Previous studies showed that activation of the abdominal core muscles enhanced the hip muscle activity in hip extension and abduction exercises. However, the lack of the direct measurement and quantification of the activation level of the abdominal core muscles during the ex...

Abstract The New Horizons spacecraft observed Pluto and Charon at solar-phase angles between 16° 169°. In this work, we use the Multispectral Visible Imaging Camera (MVIC) observations to construct multiwavelength phase curves of Pluto’s atmosphere, using limb scatter technique. Observational artifacts biases were removed as a representative airless body. size distribution haze particles constr...

Objective: The current understanding of acute neurophysiological responses to resistance training remains unclear. Therefore, we aimed to compare the time-course of acute corticospinal responses following a single-session heavy strength training (HST) of the biceps brachii (BB) muscle and provide quantifiable evidence based on the super-compensation model in an applied setting. Methods: Fourtee...
