Penelitian ini bertujuan untuk membandingkan pengaruh antara latihan small sided games (SSG) dan interval training (IT) terhadap daya tahan aerobik pemain sepakbola under-17. Sebanyak 24 pemain sepakbola U-17 yang dibagi menjadi 2 grup: grup SSG (n = 12) dan grup IT (n = 12) mengikuti program latihan selama 6 minggu. Instrumen penelitian yang digunakan adalah Yo-Yo Intermitten Recovery Test. ANAVA dua jalur digunakan untuk proses analisis data. Pemain dari kedua grup menunjukkan peningkatan yang sama pada daya tahan aerobik selama periodesasi latihan 6 minggu. Hasil ini menunjukkan bahwa SSG dan IT sama efektif dalam meningkatkan daya tahan aerobik pada pemain sepakbola U-17 (p 0.05). Effect of Small Sided Games and Interval Training on Aerobic Endurance of U-17 Soccer Players AbstractThis study aims to compare the effect of small sided games and interval training on the aerobic endurance of U-17 soccer players. 24 soccer players under 17 attended a 6-week training program divided into 2 groups: SSG group (n = 12) and IT group (n = 12). The research instrument used was Yo-Yo Intermitten Recovery Test. Two-way ANOVA is used for data analysis. Players from both groups showed a similar increase in aerobic endurance during the 6-week training period. These results indicate that SSG and IT are equally effective in developing the aerobic endurance in U-17 soccer players (p 0.05).

This study examined the nutritional and performance status of elite soccer players during intense training. Eight male players (age 17 ± 2 years) of the Puerto Rican Olympic Team recorded daily activities and food intake over 12 days. Daily energy expenditure was 3,833 ± 571 (SD) kcal, and energy intake was 3,952 ± 1,071 kcal, of which 53.2 ± 6.2% (8.3 g ⋅ kg BW−1) was from carbohydrates (CHO), 32.4 ± 4.0% from fat, and 14.4 ± 2.3% from protein. With the exception of calcium, all micronutrients examined were in accordance with dietary guidelines. Body fat was 7.6 ± 1.1% of body weight. Time to completion of three runs of the soccer-specific test was 37.65 ± 0.62 s, and peak torques of the knee flexors and extensors at 60° ⋅ s−1 were 139 ± 6 and 225 ± 9 N ⋅ m, respectively. Players' absolute amounts of CHO seemed to be above the minimum recommended intake to maximize glycogen storage, but calcium intakes were below recommended. Their body fat was unremarkable, and they had a comparatively good capacity to endure repeated bouts of intense soccer-specific exercise and to exert force with their knee extensors and flexors.

Purpose:To monitor resting salivary secretory immunoglobulin A (SIgA) levels in international soccer players during the short-term training period that precedes international match play.Methods:In a repeated-measure design, saliva samples were obtained from 13 outfield soccer players who participated in the training camps preceding 7 games (5 home and 2 away) of the 2014 FIFA World Cup qualifying campaign. Samples were obtained daily for 4 d preceding each game (and analyzed for SIgA using the IPRO oral-fluid-collection system) at match day minus 1 (MD-1), minus 2 (MD-2), minus 3 (MD-3), and minus 4 (MD-4).Results:SIgA displayed a progressive decline (P = .01) during the 4-d training period (MD-4, 365 ± 127 μg/mL; MD-3, 348 ± 154 μg/mL; MD-2, 290 ± 138 μg/mL; MD-1, 256 ± 90 μg/mL) such that MD-1 values were significantly lower (P = .01) than both MD-4 and MD-3. The 95% confidence intervals for the differences between MD-1 and MD-4 were –191 to –26 and between MD-1 and MD-3 were –155 to –28.Conclusions:Data demonstrate that a short-term soccer-training camp in preparation for international competition induces detectable perturbations to mucosal immunity. Future studies should monitor SIgA (as a practical and noninvasive measure of immunity) alongside internal and external measures of training load in an attempt to strategically individualize training and nutritional strategies that may support optimal preparation for high-level competition.
