Movement patterns and player load: insights from professional padel.

Quantifying competition load with kinematic variables from inertial devices provides critical insights into player performance, a practice well adopted especially in team sports. This study aimed to analyse load variables in elite padel players, distinguishing between match winners and losers. Data were collected from 83 players across 23 professional circuit matches.

Dose-dependent progressive sunscreens. A new strategy for photoprotection?

A new generation of UV filters has been developed that act by limiting the dose of radiation rather than by blocking a fraction of the solar irradiance on the skin surface. Such progressive sunscreens are based on the photochemical transformation of suitable precursors upon exposure to sunlight. Broadband sunscreens are thus generated "on demand", affording protection when, where, and to the extent that it is needed, providing higher protection to more exposed areas, and increasing the UV blocking capacity as the radiation dose increases.
