Objective Score

The book begins with three personal stories about the author’s early encounters with comparison, rating, and ranking. The stories demonstrate that ranking might reflect the reality of objectivity in certain cases, while in other cases objectivity is only an illusion. In addition, objectivity might even be manipulated. The first story tells why the only boy with a soccer ball in a grade-school class in postwar Budapest led his class’s popularity list. Then the author describes how subjective ratings of soccer players were aggregated to arrive at an “objective score” for each player at the end of the season. Finally, the author uses a folktale to show how the strongest member of a group can become a self-nominated judge and manipulate what ought to be a collective decision.

Background: Kicking actions have been implicated in the aetiology of soccer injuries, and the unilateral nature of kicking may influence this. The aim of the current investigation was to determine whether soccer players exhibit bilateral differences in support limb patellar tendon loads. Material/Methods: Fifteen male soccer players were examined whilst kicking a stationary soccer ball with both their dominant and non-dominant feet. Patellar tendon kinetics were obtained from each limb and then contrasted using paired samples t-tests. Results: Significant increases in patellar tendon kinetics were found when using the non-dominant limb. Conclusions: The findings from the current investigation have clinical significance and support the notion that kicking with the non-dominant limb may be associated with increased risk for patellar tendon injury aetiology.

The aim of the study was to compare internal and external load responses of different small-sided games, using balanced (5v5 Possession and small-sided games formats) and unbalanced (6v4) teams. Ten elite youth male soccer players were monitored at the start of the in-season period using global positioning system, heart rate and subjective ratings of intensity. Results showed higher physiological stress (>90% HRmax) in Possession and small-sided games formats when compared to the unbalanced teams (ES = 1.3–2.3). Total and high-intensity distance in small-sided games (28 ± 25 m) and Possession (67 ± 35 m) were greater compared to teams of 6 and 4 in the unbalanced scenario. Small-sided games format and team with six players had higher proportion of distance running at sub-maximal velocities (0–5.8 m/s2). Small-sided games format and team with four players saw greater mean acceleration effort (mean acceleration intensity in small-sided games 1.91 ± 0.27 vs. Possession 1.80 ± 0.20 m/s2, ES = 0.4 and Team 4 1.56 ± 0.24 vs. Team 6 1.44 ± .0.19 m/s2, ES = 1.3). Small-sided games format and team with 6 players had lower starting velocities prior to acceleration efforts (small-sided games 0.90 ± 0.08 and Team 6 1.11 ± 0.11 m/s2, ES = 1.5 and ES = 1.8), while velocity at the end of each acceleration effort was greater in the Possession format and Team 4 compared to small-sided games and Team 6 (Possession 3.54 ± 0.23 m/s2 and Team 4 3.13 ± 0.22 m/s2) compared to the small-sided games format (ES = 0.1) and the team with six players (ES = 2.3). These data demonstrate that using unbalanced teams can provide an additional form of training prescription to facilitate player specific training within a squad environment by providing different internal and external training responses within a combined drill.

A unique feature of soccer is the purposeful use of the head for controlling, passing, and shooting a soccer ball. Some concern has been expressed in the literature on the cumulative effects of heading on soccer players. Certain neurophysiologic and neuropsychologic changes have been reported in current or retired players, with heading being blamed. A major factor that could influence some of the findings is a player's history of concussive episodes, which are known to influence brain function. These episodes can occur during aspects of the game other than heading. We interviewed all male and female soccer players (N 137, average age 20.5 years) who competed at the U.S. Olympic Sports Festival in 1993. The mechanisms of injuries, frequency, and sequelae were determined. There were 74 concussions in 39 male players (grade I 50) and 28 concussions in 23 female players (grade I 19). For the men, 48 of the 74 episodes were from collisions with another player. For the women, 20 of 28 were from such collisions. Headaches, being “dazed,” and dizziness were the most common symptoms reported. Based on concussion history, the odds are 50% that a man, and 22% that a woman, will sustain a concussion within a 10-year period. The data indicate that concussions from player-to-player contact are a frequent hazard in soccer. Head injuries incurred this way may be more of an influence for published findings of physiologic and psychologic deficiencies than routine heading of the soccer ball.

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.

Ninety-six participants with normal hearing and 63 with severe-to-profound hearing impairment viewed 100 CID Sentences (Davis & Silverman, 1970) and 100 B-E Sentences (Bernstein & Eberhardt, 1986b). Objective measures included words correct, phonemes correct, and visual-phonetic distance between the stimulus and response. Subjective ratings were made on a 7-point confidence scale. Magnitude of validity coefficients ranged from .34 to .76 across materials, measures, and groups. Participants with hearing impairment had higher levels of objective performance, higher subjective ratings, and higher validity coefficients, although there were large individual differences. Regression analyses revealed that subjective ratings are predictable from stimulus length, response length, and objective performance. The ability of speechreaders to make valid performance evaluations was interpreted in terms of contemporary word recognition models.
