The effects of sodium bicarbonate supplementation on asoccer specific conditioning test in division III soccer players

The quality of the coach-athlete relationship is important to athlete development and overall performance in sport. To better enable coaches to foster this relationship, this study was designed to use an integrative personality framework (McAdams, 2013) to gain a deeper, more contextualized understanding of the athlete. Using a case study approach, two Division III collegiate soccer players completed a three-part survey that profiled these individuals as a social actor (layer one), motivated agent (layer two), and autobiographical author (layer three). Results are presented for each athlete, yielding rich, yet different, personality profiles. These profiles identify particular traits, motives, and personal stories that uniquely shape the personalities of these individuals. We discuss the efficacy of using McAdams’ framework as a guiding structure for helping elite coaches better understand their athletes and, subsequently, further develop the coach-athlete relationship. We also discuss the use of McAdams’ framework in the sport context and how it might provide useful insights for advancing the psychological profiling of athletes.

The Relationship

Introduction: Competitive soccer players are required to perform short passing under stressful conditions; their success may be related to their self-confidence and anxiety levels. The purpose of this study was to examine the relationship between short-passing ability and anxiety and self-confidence among collegiate soccer players. Methods: Seventeen Division III collegiate soccer players (20.0 ± 1.0 years, 65% female) completed the Athletic Coping Skills Inventory (ACSI), Sport Competition Anxiety Test (SCAT), Trait Sport-Confidence Inventory (TSCI), and Competitive State Anxiety Inventory-2 (CSAI-2R) and the Loughborough Soccer Passing Test (LSPT). Spearman’s rho (rs) was used to identify if a relationship between these inventories and LSPT time existed. Results: Mean LSPT total time was 55.7 ± 12.0 seconds. We observed positive relationships between SCAT and LSPT total time (rs = .51, p = .04) and CSAI-2R and LSPT total time (rs = .55, p =.03). Furthermore, a strong negative relationship was found between TSCI and LSPT total time (rs = -.68, p = .004). Conclusions: There is a relationship between anxiety, confidence and short-passing performance in collegiate soccer players. Coaches should consider interventions to decrease players’ anxiety and improve self-confidence in preparation for soccer competition.

Creatine and sodium bicarbonate are both ergogenic aids for athletic performance. However, research on the combined creatine and sodium bicarbonate (CSB) supplementation in soccer is limited. This study investigated the changes in soccer-specific performance in elite soccer players after supplementing with CSB. Twenty well-trained elite soccer players participated in the study (age: 20.70 ± 1.08 years; height: 173.95 ± 2.81 cm; body weight: 70.09 ± 3.96 kg; soccer experience: 8 years; average training hours per week: 20 h). The participants were randomly allocated into CSB groups (CSB, n = 10) and placebo groups (PLA, n = 10). The CSB group took creatine (20 g/day) and sodium bicarbonate (0.3 g/kg/day); these two supplements were taken four times a day (morning, afternoon, evening, and before sleep) for seven days. Soccer-specific performance was assessed via 10- and 30-m sprint, coordination, arrowhead agility, and Yo-Yo intermittent recovery level 1 tests. Compared to the PLA group, the CSB group performed better in the 30-m sprint (CSB: −3.6% vs. PLA: −0.6%, p = 0.007, effect size (ES): 2.3) and both right and left arrowhead agility (right: CSB: −7.3% vs. PLA: −0.7%, p < 0.001, ES: 2.8; left: CSB: −5.5% vs. PLA: −1.2%, p = 0.001, ES: 2.1) tests. However, there were no differences in 10 m sprints, coordination, and Yo-Yo intermittent recovery level 1 tests between the two groups (p > 0.05). In conclusion, CSB supplementation improved sprint and agility in elite soccer players. However, it is still unclear whether such effect is synergistic effect of two supplements or the result of either one of them. Therefore, caution should be taken when interpreting the results, and the limitations should be examined further in future studies.
