TO DO: Use digitize or kinovea to analyse. so, with the help of pictures and video we need to analyse in digitize and obtain data points and then we need to do calculation, graphs. you have to place the points in the pictures and present the graphs and calculations asked 0,45m in leg length his weight is 556N/n DeepL Subscribe to DeepL Pro to translate larger documents.

LUSOPHONE UNIVERSITY OF HUMANITIES AND TECHNOLOGIES DEGREE IN PHYSICAL EDUCATION AND SPORT - BIOMECHANICS Prof. Dr. Pedro Aleixo, Prof. Dr. Tiago Atalaia and Prof. Maria Bhudarally LABORATORY WORK As part of the Biomechanics course and as part of their assessment, students carry out laboratory work to describe and analyze kinematic and dynamic parameters during a jump. The document to be produced for this work should be organized as follows: 1. General presentation - University; Course; Curricular Unit; Teachers; Title of the work; Authors; 2. Introduction - Define: phases of the task; phase of the task to be described and analyzed; objective of the task; mechanical objective of the phase to be described and analyzed; 3. Methodology - define the material and procedures used; 4. Results present the results obtained; - 5. Discussion - discuss the results obtained on the basis of the material taught during the course; 6. Conclusions - present the conclusions of the work carried out. The assessment of the work is based on the document produced by the students, organized according to the previous paragraph. All the steps leading up to the laboratory work will be described below. Description and analysis of kinematic and dynamic parameters during a jump call Step 1 - Collect anthropometric data and take video of the task to be described and analyzed: 1.1. Collect anthropometric data from the performer: 1.1.1. Record the performer's weight based on the data from the force platform; 1.1.2. 2 marks defining the longitudinal axis of the right leg segment are placed on the performer, namely at the knee and ankle. The length of the segment defined by these two marks is collected so that the scale factor can be determined; Qual a medida real do segmento? Factor de escala "Teorema de Pitágoras" "Trigonometria (básica)" 1.2. Define with the performer what the objective of the task is, i.e. the performer makes two consecutive jumps, the last of which has the objective of jumping to a specific point. 1.3. The performer trains the task while adjusting to the following methodological criteria: 1.3.1. Set the image acquisition frequency (i.e. 25 images/s); 1.3.2. Define the positioning of the camera in order to define and fix the shooting plane, the capture volume and the origin of the global reference; 1.4. Collection of video and force data (platform) for subsequent data processing. Step 2 - Deconstructing the video into images separated by constant time intervals (using Kinovea): 2.1.

Define the beginning and end of the phase of the task to be described and analyzed - define the first and last image/instant of the video to be edited: 2.2.1. First image - corresponds to the image before the feet make contact with the platform (called the second jump); 2.2.2. Last image - corresponds to the last image in which the feet contact the platform (called the second jump); 2.3. Edit the video (by cutting and creating a new video between these two images; save this new video for later presentation); KINOVEA - ALTERAR A DURAÇÃO DO VÍDEO DELIMITA O INÍCIO DO VÍDEO DELIMITA O FINAL DO VÍDEO 2.4.
