“…These tasks will not only prepare the player from a physical-technical but also tactical point of view where they will develop multiple responses to situations that vary in time and space. These short-term periods should be part of injury prevention protocols [35]. https://doi.org/10.1371/journal.pone.0232123.g001…”

“…Finally, as argued in the introduction section, CODs and the forces involved in high intensity actions are fundamental in soccer kinematics because these short-term actions may be a key parameter of soccer performance [35]. These actions usually open up clear scoring opportunities [37,38] or allow the player to have a better position to shoot, unmark, pass or score [39].…”

The purpose of the present study was to: (a) assess centripetal force (CentF) and changes of direction (COD) in elite soccer players according to playing position (central defender, CD; lateral defender, LD; central midfielder, CM; lateral midfielder, LM; forward, FW), laterality (right-footed vs. left-footed) and field zone (central vs. lateral), and (b) analyze the relationship between anthropometric characteristics (age, weight, height, body mass and fat mass) and non-linear locomotion workload. Thirty professional soccer players (age: 26.57±5.56 years) were tracked during the 2017-2018 season during friendly, national and international matches (38 total games) using inertial measurement devices. CentF and COD were the variables extracted for analysis. A one-way ANOVA was used for playing position comparison, a t-test for laterality and field zone, and Pearson's correlation coefficient to analyze relationships between anthropometric characteristics and dependent variables. There were differences by playing position in COD (556.33-to-412.18), R 20 COD (484.36-to-354.81) and R 60 COD (48.38-to-38.61) (p < .01; ω p 2 = 0.03-to-0.05; CD>CM>LD>LM = FW); in COD HIA (49.75-to-37.11), R 20 COD HIA (16.04-to-9.11) and R 60 COD HIA (10.64-to-9.11) (p < .01; ω p 2 = 0.03-to-0.07; CM>FW>LM>CD = LD); in COD SPRINT (14.56-to-8.40) and R 20 COD SPRINT (3.29-to-1.40) (p < .01; ω p 2 = 0.03-to-0.04; FW = LM = CM>CD = LD); and in CentF MAX both in clockwise (992.04-to-902.09N) and counterclockwise (999.24-to-872.61N) directions (p < .02; ω p 2 = 0.02-to-0.07; FW = CD>CM = LM = LD). The highest values of counterclockwise CentF were performed by left-footed players in the central zone (p < .001; d = 0.71-to-1.44) and clockwise CentF by right-footed players (p < .001; d = 0.04-to-0.55) in the lateral field zone. Moderate correlations were found between age, body mass and high intensity/sprints COD and repeated COD ability (p < .05; r = 0.235-to-0.383). Therefore, team staff should consider anthropometric characteristics, playing position, laterality and field zone to individualize training workload related to non-linear locomotion in soccer.

“…First, the authors restricted their analysis to studies using 'wearable' microtechnologies to analyse peak demands. We are unclear as to the rationale for the omission of several key studies [2][3][4][5][6][7][8][9] using valid and reliable passive manual and optical tracking techniques to quantify peak locomotor demands in elite male and female soccer players. Indeed, the use of commercial optical tracking systems (e.g., STATS, TRACAB) for monitoring contemporary competitive performance is ubiquitous, especially in European professional soccer leagues.…”

“…This energy comes almost exclusively from high-energy phosphocreatine in the muscles, each kg of muscle containing from 3 to 8 mmol of ATP. 8 This is characterized as a production system of immediate energy production for short-term actions (10 to 15 seconds) with high intensity that have phosphocreatine as a prominent substrate that is also characterized as a limited source. 7 In soccer, moves such as sprint during counterattack situations, for example, highlight the anaerobic power.…”

Soccer is among the most complex sports because it needs several physical valences. The prevailing metabolism inside a game is aerobic but, in crucial moments of a match, part of the explosive movements from the anaerobic metabolism is activated. The maximal anaerobic power is a trainable variable that is extremely important for a soccer player and can be trained in different ways. Objective: This study aimed to analyze some methods for maximal anaerobic power training and demonstrate their importance for professional soccer. Method: This research is a literature review. We searched through books and research websites such as Pubmed and Scielo using the descriptors. The search returned 86 entries, from which 30 were filtered out and used in this review. Sprint, plyometric and interval training (game situation) are the models that stand out in the literature. Conclusion: Through this research, it is possible to conclude that the training of this variable must be done with alternating methods within the proposals and needs of the team.
