    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 versus 3.7 ± 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 versus 122.4 ± 6.8 mmHg), submaximal exercise (150.4 ± 18.8 mmHg versus 137.3 ± 9.5 mmHg), maximal exercise (211.3 ± 25.9 mmHg versus 191.4 ± 19.2 mmHg), and 24-hour BP (124.9 ± 6.3 mmHg versus 109.8 ± 3.7 mmHg). Football players also had higher fasting glucose (91.6 ± 6.5 mg/dL versus 86.6 ± 5.8 mg/dL), lower HDL (36.5±11.2 mg/dL versus 47.1±14.8 mg/dL), and higher body fat percentage (29.2±7.9% versus 23.2±7.0%). Division III collegiate football players remain an understudied population and may be at increased cardiovascular risk

    International Journal of Exercise Science 9(4): 482-490, 2016. Previous studies have investigated carotid artery intima-media thickness (IMT) and blood pressure and found a direct correlation between the two. It is known that adult females have better cardiovascular health than males until a certain stage of life, yet limited research has examined gender differences in vascular function. Thus, the purpose of this study was to investigate vascular structure and function, blood pressure, and blood glucose/cholesterol levels in relation to gender differences in young healthy adults. On three separate days, 44 adults (26.30 ±11.9yrs; 24M, 20F) completed a carotid IMT ultrasound, a flow-mediated dilation (FMD), a fasted glucose and cholesterol test, a 24hr ambulatory blood pressure monitoring, a VO2max test, and a body composition measurement. Females had lower systolic blood pressure, lower diastolic blood pressure, lower LDL/HDL ratios, lower body mass index, a higher HDL count, and lower plasma glucose levels than males (p \u3c 0.05 for all), all of which suggest better cardiovascular health. However, we found no gender differences in vascular health measures, IMT and FMD. Our results suggest that while young adult females have better cardiovascular health than males, endothelial function may not yet be affected in the young adult years

    Previous studies have shown that personal protective equipment (PPE) is responsible for increases in heart rate (HR) and VO2max response in firefighters (FF), but has not been examined in collegiate lacrosse players. We have found that FF have exaggerated blood pressure (BP) responses to a treadmill test, and during recovery when wearing PPE (data unpublished)

    Body Composition And Blood Pressure Responses In Volunteer Firefighter Population

    No full text
    The dangerous emergency scenes firefighters are called upon increase the risk of sudden cardiac death, which claims more firefighter (FF) lives than actual fires do. Prior studies have reported that wearing personal protective equipment (PPE) and a self-contained breathing apparatus (SCBA) creates CV stress in FF. Recently we examined blood pressure (BP) and heart rate (HR) responses to a treadmill test in volunteer firefighters and found that BP and HR responses are exaggerated when a firefighter wears full gear (PPE + SCBA) (data to be published). It needs to be determined whether body size affects this response
