The slope of the oxygen pulse curve does not depend on the maximal heart rate in elite soccer players

This study compared the exercise intensity of four specific soccer training sessions (friendly and training match, tactical and technical workouts). Ten professional soccer players (24.2 ± 3.7 years, 177.9 ± 7.3 cm, 63.2 ± 4.6 mLO2•kg-1•min-l) were recruited. A treadmill progressive interval test was performed to determine the players' VO2max, maximal heart rate (HRmax), HR-VO2 curve, and the heart rate corresponding to blood lactate concentrations of 2 and 4 mmol/L. The heart rate during the training sessions was used to estimate the exercise intensity and to classify them into intensity zones (low-intensity: <2 mmol/L; moderate-intensity: between 2 and 4 mmol/L; high-intensity: >4 mmol/L). Exercise intensities were different among training sessions (friendly match: 86.0 ± 5.1% HRmax; training match: 81.2 ± 4.1% HRmax; tactical workout: 70.4 ± 5.3% HRmax; technical workout: 62.1 ± 3.6% HRmax). The friendly match presented the highest percentage of time performed in the high-intensity zone.

Purpose:To quantify the seasonal training load completed by professional soccer players of the English Premier League.Methods:Thirty players were sampled (using GPS, heart rate, and rating of perceived exertion [RPE]) during the daily training sessions of the 2011–12 preseason and in-season period. Preseason data were analyzed across 6 × 1-wk microcycles. In-season data were analyzed across 6 × 6-wk mesocycle blocks and 3 × 1-wk microcycles at start, midpoint, and end-time points. Data were also analyzed with respect to number of days before a match.Results:Typical daily training load (ie, total distance, high-speed distance, percent maximal heart rate [%HRmax], RPE load) did not differ during each week of the preseason phase. However, daily total distance covered was 1304 (95% CI 434–2174) m greater in the 1st mesocycle than in the 6th. %HRmax values were also greater (3.3%, 1.3−5.4%) in the 3rd mesocycle than in the first. Furthermore, training load was lower on the day before match (MD-1) than 2 (MD-2) to 5 (MD-5) d before a match, although no difference was apparent between these latter time points.Conclusions:The authors provide the 1st report of seasonal training load in elite soccer players and observed that periodization of training load was typically confined to MD-1 (regardless of mesocycle), whereas no differences were apparent during MD-2 to MD-5. Future studies should evaluate whether this loading and periodization are facilitative of optimal training adaptations and match-day performance.

AbstractThe objective of the present study was to determine the validity of Carminatti’s shuttle run incremental test–T-Car derived parameters in estimating the maximal lactate steady state determined in shuttle run format. Eighteen soccer players performed a T-Car test, and several trials to determine the maximal lactate steady state. From T-Car were derived the heart rate deflection point, peak speed, maximal heart rate and parameters resulting from percentage of peak measures. The validity was accessed by Bland-Altman plots, linear regressions, and two one-sided tests of equivalence analysis. The results showed the speed at 80.4% of T-Car peak speed, the heart rate deflection point and the 91.4% of maximal heart rate were equivalent to maximal lactate steady state (Mean difference; ±90% compatibility interval; −0.8; ±1.5%, −0.4; ±1.1%, and 0.0; ±2.7%, respectively). Additionally, peak speed during the T-Car test was a stronger predictor of maximal lactate steady state (MLSS [km/h]=2.57+0.65 × sPeak; r=0.82 [90% CI; 0.62–0.92], standard error of the estimate=3.6%; 90% CI ×/÷1.4). Therefore, soccer players can use the T-Car derived parameters as a noninvasive and practical alternative to estimate the specific maximal lactate steady state for soccer.

Abstract The aim of this study was to compare the effects of game design modification, the type of the goal and the number of players on the intensity of play in small-sided soccer games (SSGs) in youth elite players. Twenty young soccer players (age 13.7 ± 0.5 years, body mass 57.4 ± 7.8 kg, body height 1.67 ± 7.8 m, maximal heart rate 201.1 ± 8.2 beats/min) performed three types of SSGs (possession play (PP) vs. regular goals (RG) vs. small goals (SG)) in both four-a-side and six-a-side formats. The heart rate responses were recorded and analysed as an indicator of the intensity of play. The four-a-side format obtained higher intensity of play than six-a-side for PP (p<0.05), but not for SG and RG. SG showed higher intensity of play than RG for four-a-side (p<0.001), but not for six-a-side. PP registered higher intensity of play than RG (p<0.05), but not than SG in four-a-side, whereas in six-a-side no differences were found between the three formats. In conclusion, the modification of variables such as the number of players, the game design and the type of the goal influences the intensity of play in small-sided soccer games in youth players.

Endurance training sessions and maximal strength training are different in general. That makes training sessions and aerobic, and pulmonary performance completely different in weight lifters and soccer players. Weight lifting requires maximal power and concentration, while football requires endurance, combinability and speed. Cardiopulmonary exercise testing is a basic method for evaluation of the functions of cardiovascular system in sportsmen, healthy people and in different diseases. Spiroergometry tests give additional information about the adaptation of the body to physical loadings, aerobic performance and oxygen pulse. Oxygen pulse estimates left ventricular stroke volume changes during exercise, and it is the ratio of VO2 extracted per heartbeat.The aim of the study was to investigate aerobic and cardiac performance, and the oxygen pulse of elite weight lifters and soccer players.Two groups of 12 weight lifters and 17 soccer players, men, members of elite sport teams, voluntary underwent spiroergometry test on system AT-104 (Schiller, Switzerland). There was no difference in the age between weight lifters (group WL, n=12, 19.33±1.67 years) and soccer players (group S, n=17, 20.47±1.66 years), (P>0.05). The body mass index of WL (26.4±1.47 kg/m2) and S (24.99±3.58) was also similar (P>0.05).Before the beginning of the tests we have obtained informed consent. The sportsmen denied diseases, usage of drugs and doping. Medical examinations were performed. The day before the test was without heavy physical activity. Veloergometer stepwise incremental protocol was applied.Physical working capacity, represented as peak loading was lower in group WL as compared with group S (120±13.43 vs. 160±14.62 W, P<0.0001). Maximal heart rate was higher in S as compared with WL (172.59±14.51 vs. 137.18±12.8 b.p.m., P<0.0001).Maximal level of the systolic blood pressure was higher in S as compared with WL (179.12±24.70 vs. 137.50±15.88 mmHg, P<0.0001).Maximal level of the diastolic blood pressure was higher in S as compared with WL (93.24±12.37 vs. 79.08±10.10 mmHg, P<0.0001).Not surprising aerobic performance was better in the group of the soccer players. Oxygen pulse at the level of the anaerobic threshold was higher in soccer players’ group as compared with WL (12.07±3.60 vs. 7.95±2.09, ml per beat, P=0.002), but maximal VO2pulse was similar for WL (15.15±5.40, ml per beat) and S (17.29±3.20, ml per beat), (P>0.05). There were no differences between the groups in the values of VO2pulse during the levels of loading from 30 to 120 The heart rate recovery after physical loading was determined in three grade scale (1-poor; 2-normal; 3-good) and there were no significant differences between the groups, WL (2.45±0.52), S (2.38±0.50), (P>0.05).Despite the differences in aerobic and cardiac performance between the weight lifters and soccer players there were no differences in the values of the peak VO2pulse. The values of the VO2pulse during the levels of physical loading from 30 to 120 W was similar in both groups. Further investigations are need to evaluate the importance of VO2pulse values as an index for determining the physical condition in different diseases, healthy people, and sportsmen.

Purpose: The purpose of this study was to compare the differences between measured (MHRobt) and predicted (MHRpred) maximal heart rate (MHR) in youth athletes. Methods: In total, 30 male soccer players [14.6 (0.6) y] volunteered to participate in this study. MHRobt was determined via maximal-effort graded exercise test. Age-predicted MHR (MHRpred) was calculated for each participant using equations by Fox, Tanaka, Shargal, and Nikolaidis. Mean differences were compared using Friedman’s 2-way analysis of variance and post hoc pairwise comparisons. Agreement between MHRobt and MHRpred values was calculated using the Bland–Altman method. Results: There were no significant differences between MHRobt and MHRpred from the Fox (P = .777) and Nikolaidis (P = .037) equations. The Tanaka and Shargal equations significantly underestimated MHRobt (P < .001). All 4 equations produced 95% limits of agreement of ±15.0 beats per minute around the constant error. Conclusions: The results show that the Fox and Nikolaidis equations produced the smallest mean difference in predicting MHRobt. However, the wide limits of agreement suggests that none of the equations adequately account for individual variability in MHRobt. Practitioners should avoid applying these equations in youth athletes and utilize a lab or field testing protocol to obtain MHR.

Purpose:This study was designed to quantify the daily distribution of training intensity in a group of professional soccer players in Norway based on three different methods of training intensity quantification.Methods:Fifteen male athletes (age, 24 ± 5 y) performed treadmill test to exhaustion to determine heart rate and VO2 corresponding to ventilatory thresholds (VT1, VT2), maximal oxygen consumption (VO2max) and maximal heart rate. VT1 and VT2 were used to delineate three intensity zones based on heart rate. During a 4 wk period in the preseason (N = 15), and two separate weeks late in the season (N = 11), all endurance and on-ball training sessions (preseason: N = 378, season: N= 78) were quantified using continuous heart rate registration and session rating of perceived exertion (sRPE). Three different methods were used to quantify the intensity distribution: time in zone, session goal and sRPE.Results:Intensity distributions across all sessions were similar when based on session goal or by sRPE. However, intensity distribution based on heart rate cut-offs from standardized testing was significantly different (time in zone).Conclusions:Our findings suggest that quantifying training intensity by using heart rate based total time in zone is not valid for describing the effective training intensity in soccer. The results also suggest that the daily training intensity distribution in this representative group of high level Norwegian soccer players is organized after a pattern where about the same numbers of training sessions are performed in low lactate, lactate threshold, and high intensity training zones.
