An examination of the heights and weights of members of the Parade Magazine's High School All-American Football Teams from 1963–1971 indicates no significant changes in the Body Mass Index of these elite athletes whereas an increased pattern in Body Mass Index was noted within this group from 1972–1989. The large increases in Body Mass Index after 1971 among the All-American high school football players raise interesting research questions; in particular, what portion of these gains can be attributed to improved nutrition and training techniques and what portion is the result of use of performance enhancing drugs such as anabolic steroids?

And Performance

This study aimed to compare the anthropometric and performance parameters between American football players from different high school grades and to compare their physical characteristics to the normative values for U.S. and Japanese players from previous studies. The analysis included 240 grade 10 and 11 American football players. The testing included height, body mass, broad jump, 40-yard dash, and pro-agility shuttle. The analysis was stratified by position: linemen (offensive and defensive), big skill players (fullbacks, tight ends, and linebackers), and skill players (wide receivers, running backs, and defensive backs). The only between-grade difference was body mass for linemen (Cohen’s d>0.6), with no moderate effects for all other measured variables (|d| ≦0.6). No Japanese players were better in both mass and performance measures than U.S. elite high school players. The strength and conditioning program for long-term athlete development should be established for American football players in Japan.

Prevalence Of Obesity

This article determines the prevalence of obesity among high school football players nationwide and compares obesity between position groups of football players and across team sports. We calculate body mass index (BMI) for 391 212 males participating in baseball, basketball, football, lacrosse, and soccer, then stratify BMI into commonly accepted categories and subdivide football players by position played, comparing BMI across position groups and sports. A total of 47.4% of high school football players are healthy weight (BMI = 18.5-24.9 kg/m2), 18.0% have obesity (BMI = 30-34.9 kg/m2: 12.4%) or class 2 obesity (BMI >34.9 kg/m2: 5.6%). Among linemen, 14.8% are healthy weight, 14.6% have class 2 obesity, and another 29.3% have obesity. Among non-linemen, the combined prevalence of obesity and class 2 obesity is 2.7%, comparable to other team sports. Obesity is common among high school football players, more so than among other high school athletes. Obesity and class 2 obesity are only common among linemen.

Contact Pressures

Background: The relationship between turf toe and plantar foot pressures has not been extensively studied. Two hypotheses were tested in a cohort of professional American football players: first, that a history of turf toe is associated with increased peak hallucal and first metatarsophalangeal (MTP) plantar pressures; second, that decreased range of motion (ROM) of the first MTP correlates with increased peak hallucal and first MTP plantar pressures. Materials and Methods: Forty-four athletes from one National Football League (NFL) team were screened for a history of turf toe during preseason training. Dorsal passive MTP ROM and dynamic plantar pressures were measured in both feet of each player. Anatomical masking was used to assess peak pressure at the first MTP and hallux. Results: First MTP dorsiflexion was significantly lower in halluces with a history of turf toe (40.6 ± 15.1 degrees versus 48.4 ± 12.8 degrees, p = 0.04). Peak hallucal pressures were higher in athletes with turf toe (535 ± 288 kPa versus 414 ± 202 kPa, p = 0.05) even after normalizing for athlete body mass index ( p = 0.0003). Peak MTP pressure was not significantly different between the two groups tested. First MTP dorsiflexion did not correlate with peak hallucal or first MTP pressures. Conclusion: This study showed that turf toe is associated with decreased MTP motion. In addition, increased peak hallucal pressures were found. Further study is warranted to determine whether these pressures correlate with the severity of symptoms or progression of turf toe to first MTP arthritis.

The Relationship

Objective. Today, obesity and depression are two major illnesses that are on the rise all over the world and threaten human health. This research was done to determine the relationship between Body Mass Index (BMI) and depression among Ahvaz high school female students.Method. In a descriptive-analytical study using stratified random sampling, 400 female high school students in academic year of 2013-2014 were picked and their height and weight were measured. BMI was classified based on World Health Organization classification. To assess the severity of depression, Beck depression questionnaire was used. In order to analyze the data, descriptive statistics and Pearson correlation test were used.Results. In terms of BMI 9% of students were slim, 77% were at an acceptable level, and 14% were overweight. Also, the prevalence of depression was 86.20% major depression and 13.79% moderate depression for obese persons, 10.41% major depression and 70.83% moderate depression for overweight persons, 8.78% major depression and 12.97% moderate depression for normal weight persons, and 9% moderate depression for slim persons. The relationship between BMI and depression among high school students is positive and significant (P<0.001;  r=0.555).Conclusion. There is a positive and significant relationship between BMI and the severity of depression among Ahvaz high school female students.

Background: Although some studies have observed a relationship between age of first exposure (AFE) to American football and long-term outcomes, recent findings in collegiate athletes did not observe a relationship between AFE and more intermediate outcomes at early adulthood. This, however, requires independent replication. Hypothesis: There will be no association between AFE to football and behavioral, cognitive, emotional/psychological, and physical functioning in high school and collegiate athletes. Study Design: Cross-sectional study. Level of Evidence: Level 3. Methods: Active high school and collegiate football players (N = 1802) underwent a comprehensive preseason evaluation on several clinical outcome measures. Demographic and health variables that significantly differed across AFE groups were identified as potential covariates. General linear models (GLMs) with AFE as the independent variable were performed for each clinical outcome variable. Similar GLMs that included identified covariates, with AFE as the predictor, were subsequently performed for each clinical outcome variable. Results: After controlling for covariates of age, concussion history, race, and a diagnosis of ADHD, earlier AFE (<12 vs ≥12 years) did not significantly predict poorer performance on any clinical outcome measures (all P > 0.05). A single statistically significant association between AFE group and somatization score was recorded, with AFE <12 years exhibiting lower levels of somatization. Conclusion: In a large cohort of active high school and collegiate football student-athletes, AFE before the age of 12 years was not associated with worse behavioral, cognitive, psychological, and physical (oculomotor functioning and postural stability) outcomes. Clinical Relevance The current findings suggest that timing of onset of football exposure does not result in poorer functioning in adolescence and young adults and may contribute to resilience through decreased levels of physically related psychological distress.
