Differences in strength and speed demands between 4v4 and 8v8 small-sided football games

ABSTRACT

The aims of this study were (i) to characterise the acceleration demands of two different formats of small-sided game (SSG), i.e., 4v4 + goalkeepers (4v4 + GK) and 8v8 + goalkeepers (8v8 + GK); (ii) to analyse the correlation between performance in power-based tests and acceleration-based physical loading during the two different SSG formats and (iii) to analyse the neuromuscular-induced fatigue. Eighteen adult male footballers participated in the study (20.7 ± 1.0 years, 178 ± 5 cm and 71.4 ± 2.1 kg). Baseline measurements were obtained from countermovement jumps, 15 s repeated jumps and 5 and 15 m sprints. A total of 36 min was analysed for each SSG (4v4 + GK: two sets of 3 × 6 min, and 8v8 + GK: 2 × 18 min). Heart rate, blood lactate, perceived exertion and movement pattern (GPS) were analysed. Distances covered by very-high-intensity activities and very-high-speed running were lower in 4v4 + GK than in 8v8 + GK (effect sizes (ES) = ?0.69 ± 0.67 and ?1.04 ± 0.67, respectively; very likely), while accelerations and decelerations were higher in 4v4 + GK than in 8v8 + GK (ES = 1.13–1.52; almost certainly). Blood lactate concentrations were higher (ES = 1.40 ± 0.58; almost certainly) and players perceived themselves to be more tired (ES = 0.80–2.31; almost certainly) after 4v4 + GK than after 8v8 + GK. Sprint ability in 5 and 15 m tests decreased (ES = 0.87 ± 0.58 and 0.89 ± 0.58, respectively; almost certainly) only after 4v4 + GK. This SSG format appeared more demanding in relation to repetitions and fatigue development of muscle power-based actions than 8v8 + GK. It may therefore be logical to use the former type of SSG to target development of power-related football actions.     

大负荷划船运动对血浆白介素- 8 水平的影响

细胞因子白介素-8(IL-8)与运动及机体的炎性反应有关。为观察IL-8在划船训练后的动态变化,选取有经验的划船运动员16人,随机平分为大负荷训练组(exercise group,E)及安静对照组(control group,C),训练前及训练后即刻、0.5 h1、h、10 h2、4 h测血浆IL-8及血乳酸(HL)浓度。结果发现:大负荷运动后血HL升高,但24 h内恢复;而血IL-8在运动后24 h内均显著升高(P<0.01)。提示在评定运动的负荷强度时,血HL反映骨骼肌能量代谢的变化;而IL-8作为与免疫有关的内分泌因子,能反映骨骼肌的内分泌及机体免疫功能的改变,将它们综合起来评定运动训练的负荷强度会更科学。     

高强度运动对血清IL-8表达水平的影响

目的：探讨血清IL-8表达水平与运动的相关性。方法：用酶联免疫吸附试验（ELISA双抗体夹心法）检测12名研究对象运动前后IL-8的血清水平。结果：12名研究对象运动后的IL-8血清水平较运动前有明显提高（P〈0．05）。结论：本研究结果显示运动对IL-8的表达有明显影响。IL-8在炎症及疾病发展过程中起到了重要的作用,本研究显示高强度运动对免疫系统的影响有临床应用价值。     

ABCC8基因多态与运动能力研究进展

ABCC8是ATP敏感性K+通道的调节亚基(又名SUR1),最大摄氧量关联基因定位技术显示,其所在区域与有氧耐力表型高度相关。鉴于此,目前该基因已经成为国际运动界研究的热点之一。对各国糖尿病人的研究发现,SUR1基因多态与糖、脂等能量物质代谢相关。这些能量物质在维持运动员运动能力中起重要作用,那么,其多态是否与运动员运动能力相关?国内未见报道,因此,本文将运用文献综述法,对目前已发表该基因与能量物质代谢,运动能力指标相关的研究进行概括、归纳,为在体育界对该基因开展应用研究提供参考。

Increased exhaled breath condensate 8-isoprostane after a swimming session in competitive swimmers

Objectives: This study aimed to evaluate the levels of 8-isoprostane (8-IsoP) in the airways of competitive swimmers at baseline and after a swimming session according to their airway responsiveness. Methods: Twenty-three swimmers and six lifeguards had a baseline spirometry and bronchoprovocative challenges. During a second visit, swimmers performed a usual swimming session while lifeguards stayed in the same pool environment for the same time period. Forced expiratory volume in one second (FEV₁) was measured before and 5 min after the end of the session. Exhaled breath condensate (EBC) was sampled before and 10 min after the session and EBC 8-IsoP levels were analysed by enzyme immunoassay. Change in EBC 8-IsoP from baseline to post-swimming session was calculated. Results: We observed no relationships between airway hyper-responsiveness and 8-IsoP values before or after swimming in swimmers. The levels of 8-IsoP were significantly higher after the training session (mean value 2.9, s?=?0.5 pg?mL^?1) than at baseline (mean value 1.9, s?=?0.4 pg?mL^?1) in swimmers only (p?=?.012). EBC 8-IsoP levels after the swimming session significantly correlated with the percent change in FEV₁ after swimming. Conclusions: EBC 8-IsoP levels were increased after training in swimmers but not in lifeguards, suggesting that exercise-induced hyperpnoea in a chlorinated pool environment increases airways oxidative stress.     

The effect of caffeine ingestion on 8 km run performance in a field setting

The aim of this study was to assess the effect of caffeine ingestion on 8 km run performance using an ecologically valid test protocol. A randomized double-blind crossover study was conducted involving eight male distance runners. The participants ran an 8 km race 1 h after ingesting a placebo capsule, a caffeine capsule (3 mg x kg(-1) body mass) or no supplement. Heart rate was recorded at 5 s intervals throughout the race. Blood lactate concentration and ratings of perceived exertion were recorded after exercise. A repeated-measures analysis of variance (ANOVA) identified a significant treatment effect for 8 km performance time (P < 0.05); caffeine resulted in a mean improvement of 23.8 s (95% confidence interval [CI] = 13.1 to 34.5 s) in 8 km performance time (1.2% improvement, 95% CI = 0.7 to 1.8%). In addition, a two-way (time x condition) repeated-measures ANOVA identified a significantly higher blood lactate concentration 3 min after exercise during the caffeine trial (P < 0.05). We conclude that ingestion of 3 mg . kg(-1) body mass of caffeine can improve absolute 8 km run performance in an ecologically valid race setting.

Changes in leg strength 8 and 32 h after endurance exercise

The aim of this study was to determine the effects of a single bout of endurance exercise on subsequent strength performance. Eight males with a long history of resistance training performed isokinetic, isometric and isotonic leg extension strength tests 8 and 32 h after 50 min of cycle ergometry at 70-110% of critical power. The participants also completed a control condition in which no cycling was performed. Plasma lactate and ammonia were measured before and immediately after each strength test. Isokinetic, isometric and isotonic leg extension torques were not significantly different 8 or 32 h after endurance exercise compared with the control condition ( P > 0.05). A large (50.3%), but not statistically significant, increase in plasma ammonia was evident during the strength tests performed 8 h after endurance exercise, while a significant ( P ? 0.05) increase in ammonia was also seen 32 h after endurance exercise. No significant changes in plasma ammonia were evident in the control condition. Our results suggest that leg extension strength was not compromised by an earlier bout of endurance cycling. However, metabolic activity during the strength tests might have been altered by the preceding bout of endurance exercise.
