This study aimed to improve the block starts initial acceleration performance for 100m athletes. In this research, to have faster block starts, athletes will need to work on starting block position and improve acceleration out of the blocks by using the most suitable block Pendle obliquities. Aim to investigate the during athlete block clearance fo...

The most of rotator cuff (RC) muscle injuries occur due to the lack of strength in the RC muscles. The pull-up is one of the exercises that can be used to strengthen the RC. Thus, the study provides a specific range from the pronated grip pull-up that in RC muscles strengthening. The baseball players (n=4) who mostly engage with overhead movement a...

The importance of this study was to understand the aspects of the sprint start technique of the sprinters and their maximum level of performance differs from the starting point of the starting blocks. The objective is to design a biomechanical model that identifies the effect of starting block Foot Pendle Obliquities (FPO) on athletes' performance....

Athletes must improve their Starting Block Clearance Technique (SBct) and speed out of the blocks to improve the Initial Acceleration (IA). Sprinters should build the energy elements (strength, speed, and power) necessary for IA. The research will focus on developing and implementing a training program aimed at improving the biomechanics and ex...

The focus of this study was to develop a force measurement device capable of tracking forces, moments, and the center of pressure throughout a sprint start. Both of the beginning blocks' force plates are independently adjustable, and they have a pair of force sensors (Loadcell Type- SQB/SQB-A/-SS/-ASS). Currently, commercially available expen...

One of the most competitive sports events is long jump event. Most of the athletes prioritize performance over fitness level. The aim of the study was to increase an athlete's long jump performance and overall fitness. This article describes how to determine and implement training loads for the athlete. An athlete who had stopped participating in s...

The most frequent form of injury among the athletes is the hamstring injury, which is caused by tight hamstring muscles. The aims of this study are to investigate the hamstring tightness in certain sports and whether body height, femoral length, are related to hamstring tightness. The hamstring flexibility was assessed using the popliteal angle thr...

Background: The aim of this systematical review study is to provide importance guidelines to enhance performance by selecting events and elements, and this will guide gymnasts to change or buildup their physique according to their desired and suitable events. Materials and Methods: A systematic search was conducted online using few different databa...

Background: This field of study based on identifies the main important anthropometric variables that affect for sprinting swimming performance. The intention of this review study is to provide knowledge to freestyle swimmers in order for them to choose the suitable event by discovering physique and anthropometric measures. Materials and Methods: Th...

This review study mainly focused on identifying biomechanism of Karate Roundhouse Kicking for enhance performance of karate athletes with minimum chance of injury. The purpose of this review study is to provide essential guidelines to coaches and athletes to identify the performance criteria of kicking techniques in the field of kinematics. All ori...

The purpose of this study was to identify the correct technique to perform highly executed long swing gymnastic movement: Belle Piked (BP). Two national Chinese gymnasts (58kg, 60.3kg) performed 4 repetitions of BP movement, on the middle of parallel bars with zero deduction. Reflective markers (14mm) and ten high-speed cameras (ViconT40S, 100Hz) w...

Background: The purpose of this study is to identify pandemic-affected physical activity levels, as well as the positive and negative effects on the University Athletic Team. According to the all information both male and female athletes' physical fitness levels, have shown decreased performance after the corona period. Materials and Methods: The d...

Background: The 100m sprint is one of the predominant events in the athletics discipline. Most athletes focus on skill-related fitness rather than health-related fitness. Health-related fitness components seem to be focused during their early preparation period to practice the skill-related components later. The study aimed to improve the health-re...

The triple jump is an athletic event consisting of three phases which are hop, step, and jump.
