Full text linkThe purpose of this Current Opinion article is to focus on the appropriate use of the terms 'aerobic'- and 'anaerobic'-exercise in sports medicine, in order to try to unify their use across coaches/athletes and sport scientists. Despite the high quality of most of the investigations, the terms aerobic/anaerobic continue to be used inappropriately by some researchers in exercise science. Until late 2014, for instance, 14,883 and 6,136 articles were cited in PubMed, in the field of 'exercise science', using the words 'aerobic' or 'anaerobic', respectively. In this regard, some authors still misuse these terms. For example, we believe it is wrong to classify an effort as 'anaerobic lactic exercise' when other metabolic pathways are also simultaneously involved. It has extensively been shown that the contribution of the metabolic pathways mainly depends on both exercise intensity and duration. Therefore, it is our intent to further clarify this crucial point and to simplify this terminology for coaches and sports scientists. In this regard, several research articles are discussed in relation to the terminology used to describe the predominant metabolic pathways active at different exercise durations and the oversimplification this introduces. In conclusion, we suggest that sports scientists and field practitioners should use the following terms for all-out ('maximal') efforts based on exercise duration: (a) 'Explosive Efforts' (duration up to 6 s, with preponderance of the 'phosphagens' metabolic pathway'); (b) 'High Intensity Efforts' (efforts comprised between >6 s and 1 min, with preponderance of the 'glycolytic pathway'), an
The effect of uphill stride manipulation on race walking gait
Full text linkStride length analysis represents an easy method for assessing race walking kinematics. However, the stride parameters emerging from such an analysis have never been used to design a training protocol aimed at increasing stride length. With this aim, we investigated the effects of stride frequency manipulation during three weeks of uphill (2%) training on stride length at iso-efficiency speed. Twelve male race walkers were randomly allocated to one of two training groups: stride frequency manipulation (RWM, n=6) and free stride frequency (RWF, n=6)

ANAEROBIC CAPACITIES FOR ELITE PERFORMANCE IN TAEKWONDO
No full textThe number of studies in combat sports has significantly increased in the last decade, as numerous combat sports are becoming more popular around the world. In this book, authors present current academic research from interdisciplinary combat sports arenas, including MMA, Judo, Karate and Tae Kwon Do. Furthermore, readers can find a review that explores the time-motion analysis of grappling, striking and mixed combat sports, and an overview of physiological responses to typical training sessions in official and simulated combats. Relevant physical and psychosocial changes throughout the process of maturation are addressed along with a comparison between combat sports and other forms of physical activity. This book also addresses links between oxidative stress and exercise in combat sports; injury epidemiology in judo; differences among athletes in different karate disciplines. (Imprint: Nova
