This study investigated the activity profile during small-sided games (SSG) in elite youth soccer players. Internal load (IL) including heart rate (HR) and external load (EL) such as distance covered in different speed-zones (SZ) were collected from forty-eight players of three different teams (U15, U16, U18). The investigation included a total of eighteen 5vs.5 SSGs, each consisting of four 2-minute bouts on a 40x32m pitch during spring season. Total group results (n = 48) showed a reduction in total-distance (p = 0.001; ηp2 = 0.12), high-intensity-running (p = 0.009; ηp2 = 0.09), and low-intensity-running distance (p = 0.028; ηp2 = 0.07) between bouts. Similarly, a reduction in the number of both acceleration-low (p = 0.001; ηp2 = 0.12) and deceleration-high (p = 0.003; ηp2 = 0.11) values was observed. Additionally, time spent in HR-zones 3 and 4 (p≤0.007; ηp2 ≥ 0.10), increased, with a reduction in HR-zone 1 (p = 0.000, ηp2 = 0.25). Age group comparison showed less distance covered in SZ 1 (p≤0.000; ηp2 = 0.56) and greater deceleration-high values (p≤0.038; ηp2 = 0.32) in U15 players compared to other age groups. Further, U15 showed lower values in low-intensity-running compared to U18 (p = 0.038; ηp2 = 0.22). No age-related differences were found for IL and repeated sprint ability (RSA) values. The higher EL in younger age groups should be taken into account when implementing soccer specific SSGs. In addition, HRmean values between 80–85% of HRmax and RSA numbers, which are similar to match-play data, indicate SSGs as an effective training tool to prepare youth soccer athletes for the demands of competition.

LANGUAGE NOTE | Document text in English; abstract also in Chinese. The purpose of this study is to investigate the heart rate (HR) repose and repeated-sprint performance throughout the match among Chinese elite youth soccer players. Two elite youth soccer teams each consisted of 11 players participated in the study. The HR measurement and repeated-sprint test were conducted (age: 17.1±0.85, height: 173± 5.2cm; weight: 64.2± 8.1kg). HR was recorded every 5s throughout the match, while repeated-sprint consisted of three 30m sprints separated by a 25s active recovery period that was conducted: 5min before the match (T1), 5min before the end of the first half (T2), 5min before the start of the second half (T3), and 5min before the end of the second half (T4). HR was in the range of 160-169bpm for 25% of total play time, followed by 170-179bpm for 23.6%. HR during the 46-60min was significantly lower than other intervals (P<0.05), and repeated-sprint time at T3 was significantly slower than others. The intensity of the match was lower than those found in European players, indicating the cardiovascular fitness and repeated-sprint performance are needed among the players. High-intensity and low-volume interval training, and re-warm up before the start of second half are suggested in the training program. 本研究旨在測定中國青年足球運動員比賽時的心率及重覆衝跑測試表現。對兩支分由11人組成的足球隊運動員(年齡17.1±0.85歲,身高:173±5.2釐米,體重; 64.2±8.1公斤)進行了心率測量以及重覆衝跑測試。比賽時每5秒鍾記錄一次心率。重覆衝跑測試由3次30米衝跑組成,每次有25秒動態休息。重覆衝跑測試共進行四次,分別在:賽前5分鐘(T1),中場前5分鐘(T2),下半場開始前5分鐘(T3)及比賽結束前5分鐘(T4)進行。結果在25%的比賽時間內,運動員的心率在每分鐘160-169之間,其次是23.6%的時間內為每分鐘170-179。在46-60分鐘的比賽中,運動員的心率顯著低於其他時段(P<0.05),而運動員在第三次重覆衝跑測試時的速度顯著低於其他三次測試。本次研究結果顯示比賽強度低於歐洲青年足球員進行的同類測試,說明中國青年足球運動員需要加強心肺功能及提高重覆衝跑的表現。建議訓練時進行大強度低密度的間歇訓練,及在比賽中場開始前再次進行熱身。

The aim of this study was to describe the time course (within 2 h post-exercise) of heart rate variability (HRV) recovery following a traditional repeated sprint ability (RSA) test applied to youth soccer players. Twenty-four young soccer players (18.4 ± 0.5 years) undertook the following assessments: (1) 10 min rest in the seated position for HRV assessment; (2) a repeated sprint ability (RSA) test; (3) passive recovery in the seated position for 10 min, immediately after finishing the RSA test and 1 h and 2 h post-RSA test. During the HRV measurements (using the natural log of root mean square difference of successive normal RR intervals—lnRMSSD) the participants were instructed to assume a comfortable sitting position, remaining awake and breathing spontaneously for 10 min. Magnitude-based inference was used in the analyses. After the RSA test, the post-1 h measure was almost certainly lower than the resting measure, but almost certainly higher than the lnRMSSD measured post-RSA test. The lnRMSSD post-2 h was likely lower than the resting lnRMSSD and very likely higher than post-1 h. In conclusion, lnRMSSD is severely depressed after performing an RSA test, and reactivation is incomplete after 2 h of passive recovery. This result should be considered by practitioners when applying successive training sessions within intervals shorter than 2 h.

Purpose:The purpose of the study was to assess the reliability and validity of a newly developed laboratory protocol to measure prolonged repeated-sprint ability (RSA) during soccer-specific exercise.Methods:To assess reliability, 12 youth soccer players age 15.2 ± 0.3 y performed 2 trials of a soccer-specific intermittent-exercise test (SSIET) separated by 3 months. The test was performed on a nonmotorized treadmill. A separate sample of 12 youth soccer players (15.2 ± 0.3 y) completed the SSIET while simultaneously HR, VO2, and blood lactate (BLa) were monitored. The SSIET was designed to replicate the demands of competing in one half of a soccer match while sprint performance was monitored. The test included a 5-s sprint every 2 min.Results:The mean coefficient of variation was 2.5% for the total distance covered during the SSIET and 3.8% for the total distance sprinted; measures of power output were less reliable (>5.9%). Participants covered 4851 ± 251 m during the SSIET, working at an average intensity of 87.5% ± 3.2% HRpeak and 70.2% ± 3.1% VO2peak, with ~7mmol/L BLa accumulation. A significant reduction (P < .05) in sprint performance was ob served over the course of the SSIET.Conclusion:The SSIET provided a reliable method of assessing prolonged RSA in the laboratory. The distance covered and the physiological responses during the SSIET successfully recreated the demands of competing in a soccer match.

Youth soccer performance is multifaceted, includes physical growth, biological maturation, and physical fitness, and is linked to the sporting environment to which the players are exposed. We aim to describe age-related associations in body physique, body composition, physical performance technical and tactical skills, psychological and club characteristics of male soccer players aged 12 to 14 years. A total of 157 male soccer players clustered into three age-cohorts (12, 13 and 14 years) were recruited from six soccer clubs. Anthropometric, body composition and body physique, biological maturation, physical performance, skill/game proficiency data, psychological characteristics, and clubs’ characteristics were collected. Group means were compared using analysis of variance and covariance. Fourteen years old players were significantly taller, heavier, leaner, faster, stronger, and technically more skilled than their younger peers (p < 0.05). Differences in physical performance and technical skills (p < 0.05) were found between age groups when adjusting for confounders of soccer training and biological maturation. No significant differences (p > 0.05) between age groups were found in psychological domains. Our findings suggest that age, biological maturation, and training volume are key factors influencing young soccer players’ performance and development. Further, clubs’ conditions provide players with ample resources for their success in training and competition.
