Effects of kettlebell mass on lower-body joint kinetics during a kettlebell swing exercise.

Functional training aims to provide specific adaptations due to exercise training and utilises a variety of equipment, including kettlebells. Due to the training principle of overload, a greater resistance must be applied to yield increased strength results. This study examined the effects of kettlebell mass on lower body joint kinetics in young recreationally trained adults.

Multilayer Hydrogel Capsules of Interpenetrated Network for Encapsulation of Small Molecules.

We report on a facile capsule-based platform for efficient encapsulation of a broad spectrum of hydrophilic compounds with molecular weight less than 1000 g mol. The encapsulated compounds extend from low-molecular-weight anionic Alexa Fluor 532 dye and cationic anticancer drug doxorubicin (DOX) to fluorescein isothiocyanate-dextrans with M ranging from 4000 to 40 000 g mol. The pH-sensitive hydrogel capsules with an interpenetrated network shell are synthesized by layer-by-layer assembly of poly(methacrylic acid) (PMAA, M = 150 000 g mol) and poly( N-vinylpyrrolidone) (PVPON, M = 1 300 000 g mol) on 5 μm silica microparticles followed by chemical cross-linking of the PMAA multilayers.
