Aerobic And Anaerobic

Soccer is a high-intensity intermittent team sport where both the aerobic and anaerobic energy systems contribute to the physiological demands of the game. The study aims to search and determine relationships between the values of cardiopulmonary and gas exchange indices during frequently used laboratory tests - the CardioPulmonary Exercise Test (CPET) and the Wingate Anaerobic Test (WAnT), exploring the capacity of the energy systems. Forty-seven soccer players (15.06 ± 0.84 years of age) performed both tests as Oxygen uptake (VO2), Oxygen pulse (O2HR), Pulmonary ventilation (VE), Volume of expired air (VTex), and Breath frequency (BF) were measured online using a breathby-breath cardiopulmonary exercise testing system. Ergometric achievements during WAnT: PP (Peak Power) 662.4 ± 121.2 W; AP (Average Power) 494.67 ± 98.5 W; FI (Fatigue Index) 61.2 ± 28.7%. There was no correlation between WAnT PP and AP and maximum power output in CPET. WAnT VE and VTex correlate significantly with CPET VO2max (r = .676 and r = .772, respectively). The main finding was a presence of approximately identical maximal values of cardiopulmonary parameters achieved in the very different in duration and intensity CPET and WАnT: insignificant differences between CPET versus WAnT: VO2max (55.97 ± 2.02 versus 56.02 ± 17.3 ml.kg.min-1); VEmax (133.96 ± 21.77 versus 126.77 ± 24.77 l.min-1); VTex max (2.19 ± 0.37 l versus 2.06 ± 0.43 l); BFmax (62.20 versus 75.43.min-1). We assume that when conducting WAnT with simultaneous registration of respiration, together with the indices of athletes’ power output, reliable information about the magnitude of VO2max and other cardiopulmonary parameters of players could be obtained. This will greatly facilitate the ongoing control of the exercise conditioning status of athletes.

Physical Preparation

Introdução: A contínua evolução do futebol tem exigido uma melhor preparação física dos atletas. Devido a esse fato, fisiologistas têm analisado o consumo máximo de oxigênio (VO2máx) de atletas como uma maneira de se determinar o nível de preparo físico de cada jogador.Objetivo: Avaliar a capacidade cardiopulmonar dos jogadores da Seleção Brasileira Militar de Futebol, comparando os resultados entre as diferentes posições da equipe.Métodos: Pesquisa do tipo observacional seccional. Foram avaliados 28 atletas (cinco zagueiros, cinco laterais, cinco volantes, seis meio-campistas, sete atacantes, idade entre 19 e 40 anos). Os participantes foram submetidos a um teste de esforço cardiopulmonar com um protocolo de rampa (0,4 km/h a cada 30 segundos, iniciando com 8,0 km/h), avaliando VO2, ventilação minuto, velocidade, frequência cardíaca tanto no limiar anaeróbico quanto no esforço máximo. A comparação entre as posições foi feita através da análise de variância (ANOVA) One-way (p < 0,05).Resultados: O VO2máx não apresentou diferença estatisticamente significativa entre as posições (p=0,163): 55,89 ± 7,39 ml/kg/min (zagueiros); 52,55 ± 6,21 ml/kg/min (laterais); 49,65 ± 6,22 ml/kg/min (volantes); 53,81 ± 5,18 ml/kg/min (meio campistas) e 58,35 ± 4,85 ml/kg/min (atacantes). Comportamento similar foi observado para as demais variáveis analisadas, tanto para o momento de limiar anaeróbico, quanto para o esforço máximo.Conclusão: Os atletas não apresentaram diferença tanto em relação à capacidade cardiopulmonar máxima quanto ao limiar anaeróbico, segundo posições dos jogadores o que pode ser explicado pelo período inicial da temporada de treinamento e competição.Cardiopulmonary Capacity of the Brazilian Army Soccer Team in Different Playing Positions: Early Season ProfileIntroduction: The soccer is continually evolving, and it requires better athlete’s physical preparation. Physiologists have analyzed athlete’s maximum oxygen uptake (VO2máx) to determine players physical fitness.Objective: To evaluate the cardiopulmonary capacity of the Brazilian Army Soccer Team, comparing the results among the different playing positions.Methods: Observational cross-sectional research. Twenty-eight athletes (19-40 years old) were evaluated (five defenders, five lateral midfielders, five central defenders, six central midfielders, seven forwards). Participants were submitted to a cardiopulmonary exercise testing with a ramp protocol (increment of 0.4 km/h each 30 seconds, starting at 8.0 km/h), assessing at anaerobic threshold and peak effort the following variables: VO2, pulmonary ventilation, velocity, heart rate. A ANOVA one-way was used to compare positions (p<0.05).Results: VO2máx did not presented statistical difference among positions (p = 0.163): 55.89 ± 7.39 ml/kg/min (defenders); 52.55 ±6.21 ml/kg/min (lateral midfielders); 49.65 ± 6.22 ml/kg/min (central defenders); 53.81 ± 5.18 ml/kg/min (central midfielders) e 58.35 ± 4.85 ml/kg/min (forwards). The same pattern was observed for the other analyzed variables, both for anaerobic threshold and peak effort time points.Conclusion: The athletes did not present difference as much in relation to the maximum cardiopulmonary capacity as to the anaerobic threshold, according to the positions of the players which can be explained by the initial period of the training and competitive season.

This study examined power output on jumping and sprinting tests in young soccer players of differing pubertal status, while controlling for body size with allometric scaling exponents. A total of 46 males aged 12–18 years (14.17 years) were divided into three groups: pre-pubescent ( n = 12), pubescent ( n = 22), and post-pubescent ( n = 12). Participants performed a series of tests, including the squat jump (SJ), countermovement jump (CMJ), and 10-meter and 30-meter sprint test protocols. The Post-PUB group was older ( F = 112.411, p < 0.001), more experienced in competitive soccer ( F = 8.055, p = 0.001), taller ( F = 28.940, p < 0.001), and heavier ( F = 20.618, p < 0.001), when compared to peers in the other groups. Mean differences in jumping and sprinting performances suggested a significant effect for pubertal status on performance in the 10-meter sprint (large effect size, F = 8.191, p < 0.001) and 30-meter sprint (large effect size, F = 8.093, p < 0.001) after allometric scaling. Power output derived from SJ (small effect size, F = 0.536, p = 0.001) and CMJ (small effect size, F = 1.058, p = 0.356) showed no significant differences across players of varying pubertal status. Biological maturation showed a large effect on maximal power output for sprints, but not for jumps, when the effect of body size was adjusted by statistically derived allometric exponents in young male soccer players.

Background: The reference values of young athletes for cardiopulmonary exercise testing are lacking. Expert opinions encourage production of local values specific for certain population. Patients and methods: The study population consisted of 136 healthy male caucasian athletic children and adolescents coming from one specific football school in northern Slovakia. Exercise testing with continuous electrocardiography was performed, and ventilatory parameters, oxygen uptake (VO2), and carbon dioxide (CO2) production were measured continuously with a respiratory gas analysis system. Results: Peak VO2max/kg was changing very little across the childhood, whereas the peak work rate, heart rate and O2Pulse were. Linear regression analysis showed a significant effect of age on VE/VCO2. Conclusion: This work provides a reference values for the most important cardiopulmonary variables that can be obtained during cardiopulmonary exercise testing in athletic children.

Abstract Objectives In this study we investigated the effects of hydrogen (H2) supplement, in the form of calcium bound H2 powder capsules, on aerobic and anaerobic cycling exercise. Methods Trained male subjects participated in a randomized, double-blind, crossover design trial and received H2-rich calcium powder (HCP) supplement (1500 mg/day, 2.544 μg/day of H2 gas) or H2-depleted placebo (PLA) (1500 mg/day) for 3 consecutive days. Aerobic experiment: Eighteen subjects carried out a cycling incremental exercise starting at 20 watts (W) work rate, and increasing by 20 W/2 minutes until exhaustion. Blood gases including pH, bicarbonate ion (HCO3−), partial pressures of CO2 (PCO2), metabolic profile including lactate (Lac), and electrolytes including chloride (Cl−) were measured at rest and at 120-, 200-, and 240-W work rates. Anaerobic experiment: Six subjects carried out a 30 second Wingate anaerobic exercise test (WAnT) bout with a resistive load of 7.5% of body mass. Lac was then measured at 1-, 3-, 5-, and 15-minutes following the WAnT exercise. Results Aerobic experiment: At rest, HCP had a significantly lower pH (P = 0.048), Cl− (P = 0.011), and a higher HCO3− (P = 0.041), PCO2 (P = 0.026) compared to the PLA group. During exercise, pH decrease (supplement effect: P = 0.043) and the HCO3− increase (supplement effect: P = 0.030) continued in the HCP group. Additionally, HCP did not affect peak work load and exercise duration. And no changes were noted in Lac at rest or during exercise. Anaerobic experiment: HCP did not affect peak power output or Lac recovery following WAnT. However the average power output during exercise was significantly higher in the HCP group (P = 0.019) compared to the PLA group. Conclusions HCP supplementation following 3 days of intake, slightly lowered pH during aerobic exercise, and increased average power output in the anaerobic WAnT exercise compared to the PLA group. HCP supplement might have an ergogenic effect in an anaerobic exercise setting. Funding Sources This study was supported by The Japan Society for the Promotion of Science, and the Ministry of Education, Science, and Culture of Japan. In addition, we received a research grant from the company ENAGEGATE Inc. and they provided the HCP supplement and placebo. However, no intercession, restrictions or agreements of any kind was imposed between parties regarding research design, results or publications.

AbstractThe objectives of this study were to examine (a) the prevalence of overweight/obesity, (b) the relationship between body mass index (BMI) and body fat percent (BF), and (c) the association between BMI, BF and power output in adult male soccer players. Members of competitive soccer clubs (n=169, aged 22.7±4.2yr) were examined for anthropometric characteristics and body composition, and performed the physical working capacity in heart rate 170 min−1 test (PWC170), a force-velocity test (F-v) and the Wingate anaerobic test (WAnT). Based on international BMI cut-off points, 17.8% (n=30) of participants were classified as overweight. BMI was correlated with BF (r=0.67, p<0.001) and could be predicted based on the equation BF=1.193·BMI-12.24 (standard error of estimate 2.49). BMI and BF were in inverse relationship with mean power during WAnT (r=−0.30, p<0.001; r=−0.47, p<0.001, respectively). BF was also in inverse relationship with PWC170 (r=−0.26, p<0.001) and maximal power of the F-v test (r=−0.18, p=0.020).The prevalence of overweight among participants was lower than what is observed in general population. The findings confirmed previous observations on general population about the negative effect of overweight and fatness on selected parameters of physical fitness.
