Maamer Slimani, Philip Davis, Emerson Franchini, Wassim Moalla
The aim of this short review was to summarize data pertaining to the rating of perceived exertion (RPE) methods (RPE value and session-RPE) during combat sport-specific activities (i.e., competition and training) based on many factors, including contest type (i.e., official vs. simulated vs. training), combat rounds, age of participants and muscle groups, and their correlation with physiological variables (i.e., blood lactate concentration [La] and heart rate [HR]). The current review shows higher RPE in a match of mixed martial arts (MMAs) than Brazilian jiu-jitsu and kickboxing matches and during the competitive period compared with the precompetitive period...

BACKGROUND: Mixed martial arts is a sport that has recently enjoyed a significant increase in popularity. This rise in popularity has catapulted many of these "cage fighters" into stardom and many regularly use social media to reach out to their fans. An interesting result of this interaction on social media is that athletes are sharing images of their radiological examinations when they sustain an injury. PURPOSE: To review instances where mixed martial arts fighters shared images of their radiological examinations on social media and in what context they were shared...

BACKGROUND: Muay Thai is a style of kickboxing that allows full-contact blows to an unprotected head, torso and legs, and, as in any combat sport, there is an inherent risk of injury. Previous observational studies have shown there is a substantial risk of injury in competitive kickboxing. None of these studies, however, have investigated the potential role of psychological risk factors and, consequently, little is known about the perception of injury risk among these athletes. Notwithstanding the important role risk perception may play in the occurrence and prevention of sports injuries, there is very limited empirical data pertaining to athletes in full-contact combat sports such as Muay Thai...

This paper is concerned with the establishment, maintenance, and decline of physical exercise practices. Drawing on experiences and observations taken from a carnal ethnography and rhythmanalysis of the practices involved in training in Mixed Martial Arts (MMA), I argue that maintaining this physical exercise practice is not straightforwardly an outcome of individual commitment, access to facilities, or the availability of free time. It rather depends on the synchronisation of practices: those of MMA, those that support MMA, and those that more broadly make up everyday life...

There is a lack of research documenting the weight-making practices of mixed-martial-arts (MMA) competitors. The purpose of the investigation was to quantify the magnitude and identify the methods of rapid weight loss (RWL) and rapid weight gain (RWG) in MMA athletes preparing for competition. Seven athletes (mean ± SD, age 24.6 ± 3.5 yrs, body mass 69.9 ± 5.7 kg, competitive experience 3.1 ± 2.2 yrs) participated in a repeated-measures design. Measures of dietary intake, urinary hydration status, and body mass were recorded in the week preceding competition...

Left-handers may have strategic advantages over right-handers in interactive sports and innate superior abilities that are beneficial for sports. Previous studies relied on differing criteria for handedness classification and mostly did not investigate mixed preferences and footedness. Footedness appears to be less influenced by external and societal factors than handedness. Utilizing latent class analysis and structural equation modeling, we investigated in a series of studies (total N > 15300) associations of handedness and footedness with self-reported sporting performance and motor abilities in the general population...
