标题：Modeling in Football Training: The Effect of Two Methods of Training Based on Small Sided Games and Repeated Sprints on Mood and Physical Performance among Footballers
摘要：The aim of the study was to compare the effect of additional practice/training of small-sided games (SSG) or repeated sprints (RS) on mood state, and physical performance in professional soccer players. Twenty four professional soccer players took part in this study (age: 17 ± 0.19 years). Participants were divided into two groups: small-sided gamed group (GSSG) performed 3 bouts of SSG (3 versus 3 players on 25 × 30 m pitch size) and repeated sprint group (GRS) performed 3 bouts of RS (6 × 40 + 40-m sprint with 20s of passive recovery in-between). Both groups were trained over a period of seven weeks (2 sessions/week s ) with the usual practice. The profile of mood state (POMS), the YOYO intermittent recovery test (YOYOTRT), sprint 10-m and five-jump test were conducted before and after training program. After 7 weeks of training, no changes in mood were determined, but run distance improved in both groups. Sprint time and leg strength improved in the RSG only. Coaches and physical trainers could choose between these two training modalities according to the objective of their training, keeping in mind the brief and intense actions advantages of the RS shown in the present study.
