Biomechanical Analysis Hammer Throw: The Influence of Kinematic Parameters
on the Results of Finalists World Championships
- Authors: Ratko Pavlović
  Pages: 36 - 46
  Abstract: Background: Hammer throw is the most complex athletic throwing discipline with a rotational trajectory and the strong action of several different forces that try to disable the projected throwing trajectory. Kinematic parameters are an important segment in the analysis of athletic disciplines, including hammer throw. Aim study: The aim of the study was to determine the influence of spatial and temporal biomechanical parameters on hammer throw results. Methods: The study was conducted on a sample of 56 male and female World Championship finalists (Berlin, 2009, Daegu, 2011, London, 2017). Multiple regression analysis was applied to determine the influence of defined kinematic parameters on the result performance of the throw. Result: The results of the male finalists confirmed the direct correlation between the starting speed (r=0.64 p=0.001), the first turn speed (r=0.47 p=0.017), the release velocity (r=0.86 p=0.000), the release of angle (r=0.37 p=0.049), and the inverse effect of the duration of the first (r=-0.40 p=0.046) and third turn (-0.46 p=0.020). The regression function of the male sample also confirmed the influence of starting speed, release of velocity (p=0.01 p

Methods of Biomechanical Performance Analyses in Sport: Systematic Review
- Authors: Getu Teferi; Dessalew Endalew
  Pages: 47 - 52
  Abstract: Biomechanical analysis involves the evaluation of techniques and tactics in sports. Qualitative method of analysis describes quality without the use of number. Quantitative analytical method entails the collection, measurement and evaluation of data involves the use of number. On average, athletes and coaches can only recall 30% of performance correctly. Performance analysis helps with the remaining 70% by providing accurate performance data. The main aim of this systematic review paper discusses the concept of biomechanics and the methods of biomechanical performance analyses used in sports. Sports Biomechanics professionals work with coaches and athletes to break down technique to help enhance performance and prevent injury. The objective of sport biomechanics is to provide information to coaches and athletes on sport skill techniques that will help them to obtain the highest level of athletic performance. Therefore, sport clubs, institutions, academies, managers, athletes and other concerned bodies working on development of sport and improving athletic performance for their coaching staff.

Home Based Physical Exercise for Prevention and Management of COVID-19
Pandemic and for Its Associated Consequences
- Authors: Getu Teferi
  Pages: 53 - 59
  Abstract: Corona viruses are sort of viruses that are phenotypically and genotypically diverse. The outbreak of COVID-19 starts in December 2019 in Wuhan, China. The research method of this article is a systematic review based on search strategy by used terms in relation with physical activity and Covid-19. The COVID-19 pandemic has forced many people around the world to stay at home and self-isolate for a long period of time. These leads to psychological outcomes such as depression, post-traumatic stress symptoms, panic, confusion, anger, fear, and substance misuse and develops Sedentary Death Syndrome and reduce individuals’ functional ability. Increased physical activity levels and fitness help alleviate or relieve Covid-19 associated health problems such as depression, anxiety and stress (mental health) and at this time if an individual follows a physically active lifestyle or participate regularly in home based physical activity, it has been found to be an effective way of improving fitness and overall health of individual. The effect of regular home based exercise training has a significant positive effect on overall health of individuals. Mental and physical well-being are negatively affected by sedentary habits and positively affected by active lifestyle.
