Isokinetic profile of elbow and shoulder muscle strength of seated throwers.

Throwing events such as discus, shot put, and javelin involve repetitive and explosive overhead activities in a short period, which increases the risk of upper extremity injuries. Furthermore, the available data on seated throwers are inadequately documented. Thus, this study aims to (1) describe the muscle strength profiles of shoulder external and internal rotators and the elbow flexors and extensors in seated throwers, and (2) identify the differences in muscle strength between seated throwers competing at international levels and those at national levels.

Changes in muscle quality and biomarkers of neuromuscular junctions and muscle protein turnover following 12 weeks of resistance training in older men.

The present study aimed to investigate the effects of 12 weeks of resistance training (RT) on body composition [fat mass (FM), lean body mass (LBM)], muscle quality upper and lower (MQU, MQL), muscle size [cross sectional area (CSA), quadriceps cross-sectional area (QCSA)], biomarkers of neuromuscular junctions [C-terminal agrin fragment (CAF)], and muscle protein turnover [N-terminal peptide (P3NP), 3-methylhistidine (3MH), skeletal muscle-specific isoform of troponin T (sTnT)] in older men. Thirty elderly men (age 66.23 ± 0.
