“…The body composition assessment took place first, followed by the physical assessment. The somatometry process is the same as in another study from the same authors [56]. An electronic digital scale and Seca height-measurement (Seca 220e, Seca, Hamburg, Germany) were used to measure the body mass and height of the players.…”

The aim of this study was twofold: (a) to examine the differences on physical indexes between players of different playing positions and (b) to reveal the correlations between their physical parameters and the running profile within the weekly microcycles. The subjects (n = 44) were separated into five positions: central defenders (n = 7), wide defenders (n = 9), midfielders (n = 13), wingers (n = 8) and strikers (n = 7), and all of them belonged to a professional 1st division European team during the 2020–21 and 2021–22 seasons. An incremental treadmill protocol was used to assess the VO2max, vVO2max and the vRER in the last week before the regular season. Then, during the first semesters, external load data were collected for two consecutive seasons to analyze the running profiles of the different positions. There were no differences on physical parameters between the players of various positions, but interestingly there were different correlations with the external load during the microcycles. Central defenders did not show any correlation. For the other positions, correlations were found between respiratory exchange ratio (vRER) and metabolic power efforts (MPWEF) (p = 0.028, r = 0.721) for wide defenders, between vRER and medium intensity accelerations (ACC2) (p = 0.004, r = 0.741) for midfielders, medium intensity decelerations (DEC2) (p = 0.01, r = 0.685), metabolic power zone 5 (MPW5) (p = 0.016, r = 0.652), MPWEF (p = 0.005, r = 0.725), and also between maximal rate of oxygen consumption (VO2max) and high intensity decelerations (DEC3) (p = 0.045, r = 0.564), metabolic power zone 4 (MPW4) (p = 0.026, r = 0.614), MPW5 (p = 0.017, r = 0.646), MPWEF (p = 0.01, r = 0.685). A correlation between velocity on VO2max (vVO2max) and ACC2 (p = 0.038, r = 0.733), MPW5 (p = 0.005, r = 0.873), and MPWEF (p = 0.009, r = 0.84) was found for the wingers. Finally, there was a correlation between vRER and MPWEF (p = 0.026, r = 0.866), and between vVO2max and high intensity accelerations (ACC3) (p = 0.03, r = 0.801) for the strikers. Our study supports that the external load of players in different positions during the training sessions is correlated with their physical indexes. These correlations are determined mostly by their tactical role, but not from their physical level, as there were no differences.

“…Regular aerobic exercise boosts blood flow to the brain, improves oxygenation, and stimulates neurotransmitter production that supports cognitive function (Ferrer-Uris et al, 2022). This improved cognitive function helps athletes stay focused and concentrated during practice and matches (Vardakis et al, 2022). Effective aerobic exercise provides solid physical preparation for a football season or competition (Anderson et al, 2022).…”

Background Problems: Lack of variety in aerobic exercise can cause boredom and reduce motivation to increase VO2max. Research Objectives: This study aims to assess how much influence aerobic exercise has on increasing VO2max in amateur football athletes. This involves regularly monitoring and measuring changes in VO2max levels over time. Methods: This research used a pre-experimental method; the design used was a one-group pretest and posttest design. The study used total sampling to select a population and sample of 30 amateur athletes. The instrument used was the 15-minute balke test to determine the athlete's VO2max capacity. The method used aerobic training with a 400-metre run. The data analysis technique used descriptive statistical tests, and prerequisite tests were normality, homogeneity, and hypothesis testing using the t-test with the SPSS version 26 program. Findings and Results: The analysis of the data reveals a notable improvement in VO2max following aerobic exercise. The average VO2max value increased from 55.38 during the pretest to 70.70 in the posttest phase. This increase was substantiated by the t-test results, where the calculated t-value was 10.36. Consequently, this indicates a significant enhancement in VO2max post-exercise. Conclusion: Aerobic exercise has a crucial role in increasing VO2max in amateur football athletes. Good cardiorespiratory conditioning can help improve their endurance, performance, and recovery during training and competition.
