Article Synopsis
- The study developed a Japanese version of the Kerlan-Jobe Orthopedic Clinic (KJOC) questionnaire, named the J-KJOC, to assess shoulder and elbow function in Japanese university baseball players.
- The J-KJOC showed strong reliability and validity, indicated by high Cronbach's alpha (0.88) and intraclass correlation coefficient (0.91) scores.
- Results suggest the J-KJOC is effective for this population, but more research is needed to explore its use in other overhead athletes for broader sports medicine applications.
Background: The effect of trunk stability and dynamic balance warm-up exercises on physical functional improvement remains unelucidated. This study examined whether exercises could prevent anterior cruciate ligament (ACL) injury and improve trunk muscle activation and dynamic balance in gymnasts.
Methods: This comparison study, involving gymnastics practice sessions, included 31 university gymnasts and was conducted in two periods: 1 year of observation followed by 2 years of intervention.
In Japan, the most common illicit drug is methamphetamine. It is possible to trace the origin of this drug by analyzing its organic and inorganic impurities and/or byproducts using several methods, such as GC, GC/MS, and inductively coupled plasma-mass spectrometry (ICP-MS). As reported here, one other method includes comparison of the striation lines of polymer sheet layers from packaging using a polarized light method.
