The importance of using infrared thermography (IRT) to assess skin temperature (t) is increasing in clinical settings. Recently, its use has been increasing in sports and exercise medicine; however, no consensus guideline exists to address the methods for collecting data in such situations. The aim of this study was to develop a checklist for the collection of t using IRT in sports and exercise medicine. We carried out a Delphi study to set a checklist based on consensus agreement from leading experts in the field. Panelists (n = 24) representing the areas of sport science (n = 8; 33%), physiology (n = 7; 29%), physiotherapy (n = 3; 13%) and medicine (n = 6; 25%), from 13 different countries completed the Delphi process. An initial list of 16 points was proposed which was rated and commented on by panelists in three rounds of anonymous surveys following a standard Delphi procedure. The panel reached consensus on 15 items which encompassed the participants' demographic information, camera/room or environment setup and recording/analysis of t using IRT. The results of the Delphi produced the checklist entitled "Thermographic Imaging in Sports and Exercise Medicine (TISEM)" which is a proposal to standardize the collection and analysis of t data using IRT. It is intended that the TISEM can also be applied to evaluate bias in thermographic studies and to guide practitioners in the use of this technique.

Excessive and prolonged exposure to impact acceleration during running is associated with increased injury rate. Acute use of compressive garments has been speculated to improve attenuation. However, it is unknown how longer interventions of compressive garments influence attenuation in running. 40 runners trained with compressive and placebo stockings for 3 weeks. Perception of comfort, stride parameters (rate, length) and impact acceleration (head and tibial peak acceleration, magnitude, acceleration rate and attenuation) were measured every 5 min during a fatigue run (30 min at 80% of the individual's maximal aerobic speed). Compressive stockings reduced tibial peak acceleration and magnitude compared to placebo stockings at every minute (p<0.05) except for the initial measurement (p>0.05). Moreover, compressive stockings led to a lower rate of increase in tibial peak acceleration (14%, p<0.005) and magnitude (16%, p<0.001) as a result of the development of fatigue compared to placebo stockings (24% and 26% increase, p=0.014 and p=0.003, respectively). Similar perception of comfort was reported for both garments. Training with compressive stockings for 3 weeks reduced impact acceleration and the rate of increase in acceleration compared to placebo stockings. These findings suggest that compressive stockings may play a protective role by reducing impact accelerations during running.

Padel: A Quantitative study of the shots and movements in the highperformance. J. Hum. Sport Exerc., 8(4), pp.925-931. Padel is a sport that has increasing its importance in recent years. Despite this evolution, there is a lack of scientific papers analyzing padel aspects, specifically about the quantification of movements and shots during match. The purpose of this study was to perform quantitative analyses of movements and shots in padel in order to establish the importance of each type. Twenty male professional players were recorded with a video during ten matches and movements (lateral, head-on and backward displacement, split-steps, jump for a smash, and turns pivoting on the right or left foot) and shots (direct and indirect drive, backhand, smash and lob, and direct volley) were identified, quantified and classified. A movement predominance was observed for the lateral displacement followed by head-on displacement and split-step. Direct volley (24.66%) and indirect lob (20.52%) were the most frequent shots, followed by direct smash (17.76%), indirect backhand (14.70%) and indirect drive (14.55%).
