Muscle activation during push-ups performed under stable and unstable conditions

2015

Background/Objective: The purpose of this study was to analyze muscle activation when performing push-ups under different stability conditions. Methods: Physically fit young male university students (N = 30) performed five push-ups under stable conditions (on the floor) and using four unstable devices (wobble board, stability disc, fitness dome, and the TRX Suspension Trainer). The push-up speed was controlled using a metronome, and the testing order was randomized. The average amplitudes of the electromyographic (EMG) root mean square of the anterior deltoid (DELT), serratus anterior (SERRA), lumbar multifidus (LUMB), and rectus femoris (FEM) were recorded. The electromyographic signals we…

Load Monitoring Practice in Elite Women Association Football

2021

The description of current load monitoring practices may serve to highlight developmental needs for both the training ground, academia and related industries. While previous studies described these practices in elite men's football, no study has provided an overview of load monitoring practices in elite women's football. Given the clear organizational differences (i.e., professionalization and infrastructure) between men's and women's clubs, making inferences based on men's data is not appropriate. Therefore, this study aims to provide a first overview of the current load monitoring practices in elite women's football. Twenty-two elite European women's football clubs participated in a close…

Body Mass Index in the Early Years in Relation to Motor Coordination at the Age of 5–7 Years

2017

Physical activity (PA) and body mass index (BMI) are consistently associated with motor coordination (MC) in children. However, we know very little how BMI in early childhood associates with MC later in childhood. This study investigated associations between BMI in early childhood and BMI, PA, and MC in middle childhood. Children aged 5 to 7 years (n = 64, 32 girls) were measured for MC using Körperkoordinationstest für Kinder (KTK) and for moderate-to-vigorous PA (MVPA) using triaxial accelerometers. Prevailing body weight and height were measured, and information on weight and height in early years was based on parental report of child health care report cards. Age-adjusted BMIz scores we…

Specialized Movement on the Rowing Ergometer and Post-workout Changes in Selected Peripheral Blood Parameters - a Case Report.

2018

Rowing is a sport discipline, which requires extreme physical strength and endurance and appropriate aerobic and anaerobic capacity as well. However, when the workout intensity and load is very high, exercise is associated with temporary changes in cellular metabolism and the immune system. The study included one male rower aged 28 years - the highly-skilled and experienced athlete. We determined basic cardiorespiratory fitness measures, complete blood count, and 24 clinical chemistry parameters including relevant biochemical and haematological parameters and matrix metaloproteinases activities. Maximal exercise on the rowing ergometer induced 2-fold increase in absolute counts of all leuko…

Continuous Analysis of Running Mechanics by Means of an Integrated INS/GPS Device

2019

This paper describes a single body-mounted sensor that integrates accelerometers, gyroscopes, compasses, barometers, a GPS receiver, and a methodology to process the data for biomechanical studies. The sensor and its data processing system can accurately compute the speed, acceleration, angular velocity, and angular orientation at an output rate of 400 Hz and has the ability to collect large volumes of ecologically-valid data. The system also segments steps and computes metrics for each step. We analyzed the sensitivity of these metrics to changing the start time of the gait cycle. Along with traditional metrics, such as cadence, speed, step length, and vertical oscillation, this system est…

Markerless 2D kinematic analysis of underwater running : A deep learning approach

2018

Kinematic analysis is often performed with a camera system combined with reflective markers placed over bony landmarks. This method is restrictive (and often expensive), and limits the ability to perform analyses outside of the lab. In the present study, we used a markerless deep learning-based method to perform 2D kinematic analysis of deep water running, a task that poses several challenges to image processing methods. A single GoPro camera recorded sagittal plane lower limb motion. A deep neural network was trained using data from 17 individuals, and then used to predict the locations of markers that approximated joint centres. We found that 300–400 labelled images were sufficient to tra…

«Når mange færre skal bestemme over mange fler som bor mye lenger bort» : En retorisk analyse av Senterpartiets bruk av populistiske appeller i medie…

2020

Master's thesis in Social science (SV505) Denne oppgaven er en retorisk analyse av Senterpartiets bruk av populistiske appeller i mediene. Dette temaet er aktualisert gjennom alle beskyldningene som rettes mot partiet om populisme i kjølvannet av en bemerkelsesverdig økning i oppslutning blant velgerne de siste årene. Fellesnevneren i de teoretiske forståelsene av populismebegrepet som konsulteres i oppgaven er at populisme innebærer en appell til «folket» og en fordømmelse av «eliten». Oppgavens tilnærming fokuserer på bruken av populistisk retorikk som et verktøy for politisk vinning. Datamaterialet som er analysert består av 31forskjelligedebattinnlegg skrevet av Senterpartipolitikere og…
