Abstract
This systematic review aimed to investigate the effectiveness of resistance training, particularly exercises designed based on 3D motion analysis, in improving muscle strength and balance function in elderly individuals with early knee osteoarthritis. A comprehensive search was conducted in PubMed, PEDro, Scopus, and Web of Science databases for articles published from January 2000 to December 2024. Selected studies were required to have utilized 3D motion analysis to assess movement deficits and design exercise programs. Out of 84 reviewed articles, 18 were chosen for final analysis. The results indicated that the majority of studies (86%) confirmed the effectiveness of resistance training in ameliorating knee osteoarthritis symptoms. Specifically, significant improvements were observed in functional balance (44% of articles) and reductions in knee pain (48% of articles). Furthermore, 33% of the studies reported superior efficacy for exercises designed based on 3D biomechanical analysis. These findings can significantly enhance the quality of life for patients and promote mobility safety in the elderly by reducing the risk of falls and improving joint stability. In conclusion, the findings suggest that innovative training approaches, particularly those incorporating 3D motion analysis, can play a pivotal role in optimizing rehabilitation and enhancing the quality of life for elderly individuals with knee osteoarthritis.

Abstract
The purpose of this study was to investigate the effect of soccer specific functional fatigue on hip and knee
joints angles during landing in professional players.15 soccer players with at least 2 years experience in
Kerman soccer clubs were selected randomly. To evaluate the lower extremity kinematics following
jumping and soccer specific- heading, three cameras (with50Hz) were used. To cause fatigue in subjects,
specific functional protocol similar to specific bangsbo soccer was used and Quantic sport v21 soft ware
was administrated for kinematic analysis of the recorded films. To statistical analyzing of data, descriptive
statistical methods, and paired-t test were administrated at α=0.05.Finding revealed that hip and knee
angles in sagittal and frontal plane in landing is influenced by functional fatigue. This results has been
reducing knee and hip flexion angles and increased varus in knee joint. Results demonstrated a more
erect landing posture due to a decrease in hip and knee flexion angles in the post fatigue condition.
However, functional fatigue significantly decrease lower extremity control ability in male soccer player
during landing.
