The levels of nicotine during athletic events were measured at six indoor athletic centres in Cyprus. Samples of air were pumped through a tube containing XAD-4 resin. Quantitation of nicotine was carried out by GC with a method detection limit of 0.03 microgram of nicotine, recovery ranged between 99.5 and 100.5%. Confirmation of the nicotine presence was carried out by GC/MS. The concentrations of nicotine measured were between 3.6 and 39.0 micrograms/Nm3 with a geometric mean range 6.5-28.3 micrograms/Nm3.

Purpose: To investigate technical regulation mechanisms of long-distance swimmers that differentiate optimal pacing strategies and the underlying kinematic parameters.
Methods: Twenty-one national and international swimmers were equipped with a sacrum-worn inertial measurement unit performed during 5000-m indoor French championships. Percentage of critical swimming speed (CSS), stroke rate, stroke length, jerk cost, stroke index, and mechanical proficiency score were computed by lap.

The continued effort to study gait kinematics and the increased interest in identifying individuals based on their gait patterns could be strengthened by the inclusion of data from older groups. To address this need and complement our previous database on healthy young adults, we present an addition to the Nonlinear Analysis Core (NONAN) GaitPrint database. We offer full-body inertial measurement data during self-paced overground walking on a 200 m indoor track of 41 older adults (56 + years old; 20 men and 21 women; age: 64.

Methods: Laboratory assessments, undertaken over 2 visits, examined body composition, pulmonary function, blood lactate/ventilatory landmarks, efficiency, fat/carbohydrate oxidation, primary component time-constant to steady-state [𝜏pc]) and peak oxygen consumption (V̇O2peak). Training, performance and nutritional intake were also reported.

Introduction: The aim of this study was to evaluate the effect of an Athletic Performance Program (APP), implemented as a complement to the usual training routines of a professional football team, on match performance variables in professional football players. The APP was designed to target mobility, stability, strength, multidirectional and sprint skills, which are critical for performance during competitive matches.
Methods: A prospective quasi-experimental study was conducted over three consecutive seasons.
