Article Synopsis
  • - The study addresses rising obesity and health issues in youth by examining the impact of high-intensity functional training (HIFT) during physical education, focusing on muscle mass and strength improvements.
  • - 116 adolescent males, divided into HIFT and traditional PE groups by age, showed significant gains in muscle mass and strength tests, with varying effects based on age.
  • - Results suggest that implementing a school-based HIFT program effectively enhances muscle mass and strength, offering important strategies for PE classes to combat sedentary lifestyles in adolescents.

Our primary objective was to investigate the effects of short-term core stability training on dynamic balance and trunk muscle endurance in novice weightlifters learning the technique of the Olympic lifts. Our secondary objective was to compare dynamic balance and trunk muscle endurance between novice and experienced weightlifters. Thirty novice (NOV) and five experienced (EXP) weightlifters participated in the study.

The present study aimed to evaluate the effects of a 6-week high-velocity strength training (HVST) intervention on movement velocity and strength endurance in experienced powerlifters with cerebral palsy (CP). Eleven experienced powerlifters with CP and seven from a control group (CON), were subjected to 6-week HVST. An assessment of movement velocity and strength endurance was conducted one week before (T1) and one week after (T2) the 6-week training intervention.

Background: Balance control has been shown to play a fundamental role both in everyday life and many athletic activities. An important component of balance control is the somatosensory information gained from muscle spindles and Golgi tendon organs. The changes in the muscle-tendon unit stiffness could alter the ability to detect and respond promptly to changes of an unstable environment.

Purpose: The aim of this study was to investigate whether a single bout of core stability exercises improves body balance immediately after the bout of exercise and during a retention test.

Methods: The study involved 16 women (age 22-25 years, body weight 60.5 ± 5.

Introduction: In the elderly, balance control in dynamic situations is often disrupted due to postural instability, leading to an increased risk of falls. Regressive changes are observed fastest in the free movements. As a result of the aging of the central nervous system is reduced precision, the pace of the independent precise movement and proprioception in the joints.
