Studies report that football players have high blood pressure (BP) and increased cardiovascular risk. There are over 70,000 NCAA football players and 450 Division III schools sponsor football programs, yet limited research exists on vascular health of athletes. This study aimed to compare vascular and cardiovascular health measures between football players and nonathlete controls. Twenty-three athletes and 19 nonathletes participated. Vascular health measures included flow-mediated dilation (FMD) and carotid artery intima-media thickness (IMT). Cardiovascular measures included clinic and 24 hr BP levels, body composition,VO2 max, and fasting glucose/cholesterol levels. Compared to controls, football players had a worse vascular and cardiovascular profile. Football players had thicker carotid artery IMT (0.49 ± 0.06 mm versus 0.46 ± 0.07 mm) and larger brachial artery diameter during FMD (4.3±0.5 mm versus3.7±0.6 mm), but no difference in percent FMD. Systolic BP was significantly higher in football players at all measurements: resting (128.2±6.4 mmHg versus122.4±6.8 mmHg), submaximal exercise (150.4±18.8 mmHg versus137.3±9.5 mmHg), maximal exercise (211.3±25.9 mmHg versus191.4±19.2 mmHg), and 24-hour BP (124.9±6.3 mmHg versus109.8±3.7 mmHg). Football players also had higher fasting glucose (91.6±6.5 mg/dL versus86.6±5.8 mg/dL), lower HDL (36.5±11.2 mg/dL versus47.1±14.8 mg/dL), and higher body fat percentage (29.2±7.9% versus23.2±7.0%). Division III collegiate football players remain an understudied population and may be at increased cardiovascular risk.

Background: To what extent pre-season training camp may impact body composition and metabolism in collegiate football players is unknown. Objective: The purpose of this study was to assess changes in body composition, dietary habits and metabolism following pre-season training in Division III American football players. Methods: Seventeen Division III football players (Ht: 1.80±0.6 m; BM: 99.1±60.1 kg; FFM: 79.7±8.6 kg; BF%: 19.3±8.6%) had their body composition and resting energy expenditure (REE) assessed in a fasted state (>12 hr.) before and upon completion of pre-season training. Pre-season training consisted of 14 days of intense training. Results: Linemen had a higher body mass, fat-free mass (FFM), and fat mass likely contributing to the higher REE (p < 0.01). A main effect for time was observed regarding changes in FFM (p<0.001) and body fat % (p = 0.024). A significant interaction was observed for FFM with linemen experiencing a greater reduction in FFM (-1.73±0.37 vs. -0.43±0.74 kg; p<0.001). Linemen (L) experienced a greater reduction in REE compared to non-linemen (NL) (L: -223.0±308.4 vs. NL: 3.27±200.1 kcals; p=0.085) albeit not statistically significant. Non-linemen consumed a higher amount of daily calories (p=0.036), carbohydrates (p=0.046), and protein (p=0.024) when expressed relative to body mass. Conclusion: The greater size in linemen prior to pre-season likely contributed to their higher REE. However, the multiple training bouts appeared to reduce REE in linemen, which may have been driven by the observed losses in FFM and low protein intake. Further, pre-season training increased body fat % in all players.
