Background: The formation of large accelerations on the head and cervical spine during a backward fall is particularly dangerous due to the possibility of affecting the central nervous system (CNS). It may eventually lead to serious injuries and even death. This research aimed to determine the effect of the backward fall technique on the linear acc...

(1) Background: This research aimed to determine the effect of the backward fall technique on the sagittal linear acceleration of the head in students training in different sports. (2) Methods: The study involved 41 students divided into two study groups. Group A included 19 students training in martial arts who practised falls with side aligning o...

(1) Background: The aim of this article is to investigate the susceptibility to head injuries in physical education students who do not train a specific sports discipline and those who use the fall performed backward with side aligning of the body technique. The other goal is the biomechanical analysis of the impact of the fall technique on the lik...

Background & Study Aim: Fall is one of leading cause of unintentional injuries and may lead to temporary or permanent disability. Susceptibility test of body injuries during a fall (STBIDF) was designed to assess subconscious way of body control during a dynamic change of the vertical posture towards lying on your back. Recent studies did not revea...

There are jobs with high risk of a fall. It seems reasonable to create a device for diagnosis and improving safe fall skills for workers. The aim of the present study was a verification of usability of a rotating training simulator for assessing motor habits during a fall caused by an external force by conducting validation procedure. Material and...

The purpose of the present work is to review the key research methods as well as the existing knowledge of biomechanics on human motor safety when during a fall. The second goal of the paper is a biomechanical analysis of falls performed in a rotational motion on the ground, by reference of the movement of a man to a car wheel rolling. The analysis...

Background and Study Aim. The aim of present study was verification of rotating training simulator (RTS) as an assessment tool of susceptibility of the body injuries during the fall caused by an external force. Material and Methods. A Group of 68 students of physical education from University of Zielona Góra were tested. Appropriateness was determi...

Trampolining is qualified as a form of extreme physical activity (extreme sport), however its extreme nature is mainly determined by the coordination difficulty, whereas threat to health or life is above average. This paper has two primary objectives: 1) to provide reasoning based on biomechanics related to the risk of injuries during falls on the...

Background and Study Aim: This study's purpose was to test the effectiveness of various methods of teaching aikido to children. Another goal was to see how the knowledge of biomechanics with regard to the principles of mechanics used in aikido techniques affects their execution. Material/Methods: The research involved a population of fourth-form pu...

Purpose: This paper aims to examine how the knowledge of biomechanics, specifically of mechanics principles used in teaching aikido techniques, affects the precision of aikido movements execution. It also aims to answer the question whether secondary-school teaching of solid-state mechanics, using examples from aikido and other sports, improves the...

In scoliosis, a slanting pelvis position in the frontal plane may give rise to a mechanical link leading to inappropriate distribution of the gravity force on individual spinal components and, ultimately, to the development of a force rotating the vertebrae. The author analysed gravity-induced variations in load on the hip joint as a result of a sl...

Study aim: The aim of the paper was to examine the influence of aikido exercises on pelvis placement in the frontal plane at children. Material/methods: The subject of investigation were boys with asymmetry of placement of back hip spurs and with indication to apply heel pads on the side of pelvis lowering in the frontal plane. Also boys at whom th...

The main aim of this article is to provide physiotherapists, physicians, corrective exercise instructors and all persons responsible for the prevention and treatment of scoliosis with factual arguments justifying the need to pay more attention to examining the position of the pelvis in children. Early detection of abnormalities in pelvic position i...

Study aim: To examine the effects of aikido exercises on the angles of lateral spinal curvature in frontal plane in cases of scoliosis. Material/methods: A group of 202 boys aged 7-10 years participated in the study. They were divided in 3 groups: experimental (subjected to aikido exercises; n = 68), corrective (subjected to conventional corrective...
