Acrobatics and Tumbling (A&T), an emerging National Collegiate Athletics Association (NCAA) sport, involves athletes with rigorous training backgrounds, usually extending from youth through early adulthood. This study examines the sleep health, diet quality, and lipid profile of A&T athletes clustered by their performance position. Forty-two A&T athletes, clustered as tops (n = 19; age = 19.6 ± 1.0 years; body mass index [BMI] = 22.3 ± 1.7 kg/m2) and bases (n = 23; age = 19.6 ± 1.3 years; BMI = 25.7 ± 2.5 kg/m2), completed preseason sleep and diet quality (Rapid Eating Assessment for Participants–Shortened [REAP-S]) surveys. Fasting blood samples were collected for lipid analysis. Body composition was assessed via dual-energy X-ray absorptiometry. Most athletes (71.4%; base n = 14, top n = 16) reported insufficient sleep (≤7 hours) and "good" sleep quality (90.4%, n = 38; base n = 18, top n = 20). Average REAP-S score was 29.24 ± 3.74. Approximately 31% (n = 13) displayed at least one undesirable lipid concentration according to medical guidelines for normal levels (total cholesterol [TC] < 200 mg/dL, triglycerides [TG] < 150 mg/dL, high-density lipoprotein cholesterol [HDL-C] > 40 mg/dL, low-density lipoprotein cholesterol [LDL-C] < 130 mg/dL). Approximately 20% exhibited elevated TC (top n = 4, base n = 4), 12.5% had elevated TG (base n = 5), 2.5% showed low HDL-C (base n = 1), and 10% presented elevated LDL-C (top n = 2, base n = 2). Most athletes experienced suboptimal sleep (≤7 hours/night) and 31% displayed at least one undesirable lipid concentration (elevated TC, TG, or LDL-C or reduced HDL-C). Tailoring interventions with sports dietitians is recommended, focused on increasing monounsaturated and polyunsaturated fat intake while reducing saturated fat consumption. These interventions could mitigate cardiovascular risks, improve recovery, and possibly enhance athletic performance. [ABSTRACT FROM AUTHOR]

Acrobatics & Tumbling (A&T) is an emerging sport in the National Collegiate Athletic Association that lacks research regarding the dietary intake and health of A&T student-athletes (A&Tsa). This study assessed the dietary intake adequacy, estimated energy availability (EA), self-reported menstrual health, and body composition of A&Tsa. Twenty-four female A&Tsa participated during week 8 of the preseason (11 top: Age= 20.1 ± 0.9 years; BMI= 22.1 ± 1.7 kg/m2; 13 base: Age= 19.5 ± 1.3 years; BMI= 26.2 ± 2.7 kg/m2). Total energy intake (TEI) and macronutrient intakes were assessed via a paper-based 3-day dietary recall. Resting Metabolic Rate [RMR = 500 + 22 * fat-free mass (FFM)] and energy availability [EA = (TEI – exercise energy expenditure)/FFM)] were estimated; and LEAF-Q assessed menstrual health. Body composition was measured using Dual-Energy X-Ray Absorptiometry. Macronutrient intakes and EA were compared to sports nutrition recommendations (carbohydrate: 6–10 g/kg; protein: 1.2–2.0 g/kg) and the Acceptable Macronutrient Distribution Range (carbohydrate: 45–65%; protein: 10–35%; fat: 20–35%). TEI was 1753 ± 467 kcal (top) and 1980 ± 473.8 kcal (base). A total of 20.8% of A&Tsa failed to meet RMR with TEI, with a higher prevalence in the top (-266 ± 219.2 kcal, n = 3) vs. base (-414.3 ± 534.4 kcal, n = 2) A&Tsa. Top and base A&Tsa had both low EA (28.8 ± 13.4 kcals·FFM−1; 23.8 ± 9.5 kcals·FFM−1) and inadequate carbohydrate intake averages (4.2 ± 1.3 g/kg; 3.5 ± 1.1 g/kg, p < 0.001), respectively. A total of 17% of A&Tsa reported secondary amenorrhea, with a higher prevalence in the top (27.3%, n = 3) vs. the base (7.7%, n = 1). TEI and carbohydrate intake of the majority of A&Tsa were below recommendations. Sports dietitians should encourage and educate A&Tsa about following an adequate diet that meets energy and sports-specific macronutrient needs. [ABSTRACT FROM AUTHOR]
