Magnesium oxide, a low-price laxative without a habit-forming tendency after long-term use, is widely used for treating constipation in Japan. However, its use has been associated with hypermagnesemia in patients with impaired magnesium excretion function such as renal insufficiency. Therefore, in this study, we investigated the use of magnesium oxide tablets, which may be administered to the elderly on a long-term basis. We found the total number of prescriptions has increased year by year and exceeded 4 billion tablets in FY 2020. The use and number of prescriptions were highest among individuals in their 80s, and more than 70% of patients taking the drug are aged 70 years or older. Since the elderly experience physiological functional decline, pharmacists must make effective use of not only age but also laboratory data listed on prescriptions when dispensing these medications in order to prevent adverse events.

The purposes of this study were to classify jumping techniques in the preparatory and take-off phases of elite male long jumpers in official competitions by using a cluster analysis and to identify biomechanical characteristics of classified technique types. The preparatory and take-off motions of 29 elite male long jumpers in official competitions were collected three-dimensionally using two high-speed cameras. Their jumps were classified into four types of jumping technique by using the Ward’s method of cluster analysis with the take-off angle as a parameter. The four types were named the Horizontal (H-type), Semi-Horizontal (SH-type), Semi-Vertical (SV-type), and Vertical (V-type) types. There were no significant differences in jumping distance among the types. H-type jumpers were characterised by a forward lean of the trunk and a larger swing leg knee flexion during the preparatory phase. V-type jumpers flexed the knee joint of the support leg more during support phase in the last stride and showed a larger backward lean of the trunk at touchdown of the take-off foot. SH- and SV-types were located between H-type and V-type jumpers. This classification will help coaches and jumpers to select appropriate techniques.
