Biomechanical properties of the discus throw: analytical case study of the Paralympic record holder in the F33 category.

Purpose: The study aims to determine the kinematic and kinetic characteristics of the discus throwing competition for the Paralympic record holder in the F33 category, the champion Hani Al-Nakhli, silver medalist in the London 2012 Paralympic and the World Champion in the discus throw (height: 1.71 m, weight: 96 kg, age: 35 years, training age: 14 years).

Methods: The player's performance was photographed during a training session in the middle of the competitive phase of the 2021/2022 season using three GoPro Hero 6 cameras, each set at a frame rate of 60fps.

Lower fitness levels, higher fat-to-lean mass ratios, and lower cardiorespiratory endurance are more likely to affect the body mass index of Saudi children and adolescents.

Background: Several studies suggest that health-related physical fitness may play a prominent role in preventing obesity in children and adolescents.

Objectives: The present study examined fitness levels using five components of health-related fitness in Saudi students aged 10-17 years (fat-to-lean mass ratio, cardiorespiratory endurance, upper body strength and endurance, abdominal muscle strength and endurance, and flexibility). Subsequently, the association between BMI and a health-related fitness index (HR-PFI) based on the five fitness components was investigated.
