The aim of the study was to determine the effects of short-term (4 weeks, twice a week: 8 sessions) plyometric training on agility, jump, and repeated sprint performance in female soccer players. The study comprised 17 females performing this sports discipline. The players were randomly divided into two groups: with plyometric training (PLY) and the control (CON). All players followed the same training program, but the PLY group also performed plyometric exercises. Tests used to evaluate physical performance were carried out immediately before and after PLY. After implementing the short PLY training, significant improvement in jump performance (squat jump: p = 0.04, ES = 0.48, countermovement jump: p = 0.009, ES = 0.42) and agility (p = 0.003, ES = 0.7) was noted in the PLY group. In the CON group, no significant (p > 0.05) changes in physical performance were observed. In contrast, PLY did not improve repeated sprint performance (p > 0.05) among female soccer players. In our research, it was shown that PLY can also be effective when performed for only 4 weeks instead of the 6–12 weeks typically applied.

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。

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.

Ergogenic strategies have been studied to alleviate muscle fatigue and improve sports performance. Sodium bicarbonate (NaHCO3) has improved repeated sprint performance in adult team-sports players, but the effect for adolescents is unknown. The aim of the present study was to evaluate the effect of NaHCO3 supplementation on repeated sprint performance in semiprofessional adolescent soccer players. In a double-blind, placebo-controlled, crossover trial, 15 male semiprofessional adolescent soccer players (15 ± 1 years; body fat 10.7 ± 1.3%) ingested NaHCO3 or a placebo (sodium chloride) 90 min before performing the running anaerobic sprint test (RAST). A countermovement jump was performed before and after the RAST, and ratings of perceived exertion, blood parameters (potential hydrogen and bicarbonate concentration), and fatigue index were also evaluated. Supplementation with NaHCO3 promoted alkalosis, as demonstrated by the increase from the baseline to preexercise, compared with the placebo (potential hydrogen: +0.07 ± 0.01 vs. −0.00 ± 0.01, p < .001 and bicarbonate: +3.44 ± 0.38 vs. −1.45 ± 0.31 mmol/L, p < .001); however, this change did not translate into an improvement in RAST total time (32.12 ± 0.30 vs. 33.31 ± 0.41 s, p = .553); fatigue index (5.44 ± 0.64 vs. 6.28 ± 0.64 W/s, p = .263); ratings of perceived exertion (7.60 ± 0.33 vs. 7.80 ± 0.10 units, p = .525); countermovement jump pre-RAST (32.21 ± 3.35 vs. 32.05 ± 3.51 cm, p = .383); or countermovement jump post-RAST (31.70 ± 0.78 vs. 32.74 ± 1.11 cm, p = .696). Acute NaHCO3 supplementation did not reduce muscle fatigue or improve RAST performance in semiprofessional adolescent soccer players. More work assessing supplementation in this age group is required to increase understanding in the area.
