Computerized Agility Training Improves Change-of-Direction and Balance Performance Independently of Footwear in Young Adults.

Unlabelled: Understanding the effects of training in different footwear on sporting performance would be useful to coaches and athletes.

Purpose: This study compared the effects of computerized agility training using 3 types of footwear on change-of-direction and balance performance in young adults.

Method: Thirty recreationally active young adults (M = 22.

Effects of footwear condition on maximal jumping performance.

The purpose of this investigation was to examine the effects of footwear on kinetics and lower extremity electromyographic (EMG) activity during the vertical jump (VJ) and standing long jump. Fifteen men performed the 2 jump types in 3 footwear conditions: barefoot, minimal shoes, and cross-training shoes. Jump displacement and kinetic data were collected, along with EMG activity of the biceps femoris, medial gastrocnemius, peroneus longus, semitendinosus/semimembranosus, soleus (SOL), tibialis anterior, vastus lateralis, and vastus medialis.

Anomalous intramolecular C-H insertion reactions of rhodium carbenoids: factors influencing the reaction course and mechanistic implications.

The intramolecular insertion of rhodium carbenoids into the alpha-C-H bonds of allylic ethers to give 3(2H)-furanones has been explored. Cyclopropanation is favored irrespective of the complex used for carbenoid generation or the substitution pattern of the allylic ether, unless a substituent is placed on the tether connecting the ether to the alpha-diazo ketone. Unusual acetal products resulting from an anomalous C-H insertion process are obtained in addition to the expected 3(2H)-furanones formed by conventional carbenoid C-H insertion.
