Introduction: Accelerometers are used to quantify energy expenditure in field research.The ActiGraph™ GT1M (ActiGraph™) is a commonly accelerometer for FitBit ® Ultra (FitBit ) low-cost alternative the ActiGraph™; however, there limited research on validity of this device.Purpose: The pilot study compares against and metabolic cart measurement step counts during treadmill walking.Methods: Thirty-two (25 female) adults, mean age 22±2 years, performed two thirty-minute phases walking (slow...

The purpose of the present study was to examine body composition National Football League (NFL) players before start regular season. Four hundred eleven NFL were measured for height, weight and lean, fat, bone mass using dual-energy x-ray absorptiometry (DXA). Subjects categorized by their offensive or defensive position comparison. On average, positions that mirror each other (i.e., lineman [OL] vs. [DL]) have very similar composition. Although OL had more fat than DL, they in total upper...

Objective The purpose of this study was to measure the linearity visceral adipose tissue (VAT) accumulation with measures total body adiposity determine whether a threshold exists and explore association cardiometabolic risk factors in adults. Methods Using cross-sectional design, data were obtained from 723 adults (324 females) age 19-47 years. Body mass index ranged 15 52 kg/m2. Segmented linear regression used identify sex-specific percent fat thresholds at which VAT slope changes. Linear...

Abstract The purpose of this study was to compare the muscle-to-bone (MBR) and soft tissue-to-bone ratios (SBR) 459 track field athletes across event groups identify differences in MBR SBR. Dual X-ray absorptiometry provided total regional (i.e., arm, leg, trunk) lean mass (LM), fat (FM), bone mineral content (BMC). calculated by dividing LM BMC. SBR LM+FM Kruskal-Wallis tests were used groups. Dunn’s post-hoc utilized adjust for multiple comparisons. Total females higher throwers compared...

Abstract This study aimed to examine body composition using dual X-ray absorptiometry (DXA) in male and female NCAA Division I collegiate basketball athletes. Two-hundred ten (male [M]/female [F]=88/122) athletes’ total regional fat mass, lean bone mineral density, visceral adipose tissue were measured. Athletes classified as: point guards (M/F=27/34), shooting (M/F=18/27), small forwards (M/F=13/18), power (M/F=21/27), centers (M/F=9/16). ANOVA Tukey’s HSD assessed positional differences by...

The purpose of this study was to evaluate total, regional, and throwing versus non-throwing arm body composition measures across the 4 major positions NCAA Division I female softball players using dual X-ray absorptiometry (DXA) (n=128). Total regional total mass (TM), fat (FM), lean (LM), bone mineral density (BMD), content (BMC), visceral adipose tissue were measured. Athletes separated into: pitchers (n=32), catchers (n=13), outfielders (n=39), infielders (n=44). ANOVA Tukey's HSD...

Abstract The purpose of this study was to examine body composition National Collegiate Athletic Association Division I female soccer players by position and season. One hundred seventy-five athletes were categorized positions forward (n=47), midfielder (n=51), defender (n=57), goalkeeper (n=20). A dual X-ray absorptiometry scan assessed percent fat, total lean mass, fat arm leg mass visceral adipose tissue. Goalkeepers had significantly higher total, arm, compared all other (p<0.05). For...
