Study on professional football players – factors in recovery and preparation and performance markers during scheduled training session

ABSTRACT

Purpose. The purpose of the present study is to estimate if the athletes can satisfy their energy needs by diet, if they are well hydrated before training, and if the training is effective.

Methods. Ten players of the football team in the B professional league participated in the study (age 23.44 ± 5.98 years, weight 70.64 ± 4.57 kg, height 176.4 ± 7.35 cm; ±SD). Their body composition was analyzed with the Body Composition Analyzer IoI 353 and they completed food questionnaires. Blood lactate concentrations were determined using the biochemical analyzer BIOSEN – C Line, EKF Diagnostic. The heart rates of the subjects are recorded using the activePULS, MEDION AG. Data was processed using SPSS and Graphpad Prism software.

Results. According to the data obtained from the food questionnaires all subjects received the necessary amount of energy to fully meet their energy needs. From the multiple linear regression, it is seen that the highest value has the standardized coefficient in front of the carbohydrate intake which means that it has the greatest influence (about 65%) on total energy intake. The heart rates of participants in the study range from 78 to 90% of the predicted maximum, i.e., high intensity. Differences in blood lactate concentration before and after exercise are significant, evidence of effective performance on training.

Conclusions. We can conclude that according to the nutrition questionnaire the athletes received a sufficient amount of macronutrients and sufficient amount of energy for their training needs. The change in blood lactate concentrations and heart rate during training is indicative of the responsible attitude of the players, and therefore the target endurance is most likely to be achieved.

Applications in Sport. Reported methods could be a useful tool for coaches to track the recovery and preparation of the athletes in season and to evaluate their performance during a scheduled training session.

ABSTRACT
The purpose of the present study was to determine whether any relationship existed between team identification levels and gambling preferences of sport consumers who put bets on the games of their supported football team. The subject group of the study was composed of university students (N=223) who were participating in football bets. Turkish version of Sport Spectator Identification Scale (15) and a vignette developed by the researchers, to identify the bettors’ team preferences while placing bets on the games (national league, European league and derby games) of their supported team, were the data collection instruments. According to the 3×2 Two-Way Contingency Table analysis, results pointed that significant relationship existed between the team identification level and betting preferences only in the case of derby games, (χ2(2, N=223), 6.03, p=.04, Cramer’s V= .164). No significant relationship was identified between the team identification levels and betting preferences of the subjects in the cases of national league, (χ2(2, N=223), 3.47, p=.18, Cramer’s V= .125) and European league games, (χ2(2, N=223), 3.92, p=.14, Cramer’s V= .133). As a conclusion, it could be said that team identification is a determinant factor in bettors’ team preferences in derby games. The results of this study would be beneficial in identifying the betting behavior pattern of football gamblers who constitute a huge market in sport industry.

Position-Specific Task, Strength, and Performance Comparisons between NCAA Division I Offensive and Defensive Linemen

Submitted by Garrett M. Hester, Bert H. Jacobson, Ty B. Palmer, Doug B. Smith and Matthew S. O’Brien

ABSTRACT

The ultimate goal of strength and conditioning practitioners is to improve performance on the field. To date, little data exist that provides evidence of strong relationships between selected exercises and sport-specific tasks. PURPOSE: The purpose of this study was to compare the performance of a position-specific task on the MAXX Football Sled Device (MX) between NCAA Division I offensive (OL) and defensive linemen (DL) and to determine the associations among selected strength and performance variables with results on the MX. METHODS: Offensive (n = 12) and defensive linemen (n = 14) (age 20.11 ±1.49 yrs) performed 10 “fire-off-and-drive” repetitions on the MX from a three-point stance. Data relative to force (N) and movement time (MT) was collected for each repetition on the MX. The duration between each repetition was automatically randomized between 6 to 10 sec. Strength and performance data including 1 RM of the squat, bench press, and power clean, along with vertical jump, 10 yd sprint, 40 yd sprint, and body fat percentage were gathered as part of seasonal standard assessment. RESULTS: Results yielded significant differences in body weight, sprint performances, 1 RM squat, and a near significant difference in MT (p = 0.052) between OL and DL. With respect to performance on the MX, there were no significant associations among selected strength and performance measures and MT on the MX. Although insignificant, force on the MX was found to have moderate associations with the 10 yd sprint (r = .457) and 1 RM power clean (r = .463). CONCLUSIONS: Primarily, these results point out that little carry over exists between the standard exercises performed and the task performed on the MX. Further research for the purpose of finding exercises that correlate with a position-specific task in these athletes is warranted. APPLICATION IN SPORT: A priority among practitioners is to remain cognizant of the positional role differences and distinct physical characteristics between OL and DL. The OL and DL positions should be categorized separately so that specific evaluative and training needs can be met for each position.

D. in Sport Administration with a minor in statistics and Research Methods from the University of Northern Colorado; a master of science in Sport Management from the University of Massachusetts at Amherst and a bachelor’s degree in sport management from Iowa State University.

Abstract

The purpose of this study was to determine the effect of elite individual athletes in NCAA Division I-A football on undergraduate admissions applicants to their respective institutions, an examination of what the media has labeled as the “Flutie Factor”. Using a pretest-posttest control group design, a statistically significant time-by-group interaction effect was found, with universities realizing a 6.59 percent increase in undergraduate applicants for admission in the year following having a football player finish among the top five vote recipients for the Heisman Trophy.
