In a comment on several articles on the vegan dietary pattern, Antoniazzi & Acosta-Navarro (2017) mentioned the paradox of the presence of dietary cholesterol as a nutritional component in the analysis of the vegan dietary pattern [1]. [..

It was the aim of the present study to compare the quality and the contributing components of vegan, vegetarian, semi-vegetarian, pesco-vegetarian and omnivorous diets.

The aim of the present study was to compare nutritional intake and the results of dietary pattern analysis in properly matched vegetarian and omnivorous subjects.
Methods: Vegetarians (n = 69) were recruited via purposeful sampling and matched non-vegetarians (n = 69) with same age, gender, health and lifestyle characteristics were searched for via convenience sampling.
Sprinters are advised to include additional protein sources in their diet. Basal metabolism and vigorous physical activities generate hydrogen ions that need to be buffered. The present follow-up study estimates the dietary potential renal acid load (PRAL) and net endogenous acid production (NEAP) in adolescent sprint athletes.

It was the purpose of the present study to compare nutritional and physical characteristics in matched samples of institutionalized vegetarian (V) and non-vegetarian (NV) elderly.
Methods: Twenty-two female and 7 male V (females: 84.
Macronutrient intake, height, weight, and body composition of 60 adolescent sprint athletes were estimated every 6 months over 3 years. Seven-day food records were analysed based on the Belgian and Dutch food databanks. The age of participants at the start of the 3-year study was 14.

A three-day food record and a health questionnaire were completed by 106 V and 106 NV matched for following characteristics: sex, age, BMI, physical activity, tobacco use and alcohol consumption. Total energy intake was not significantly different (men: V: 2,346 ± 685 kcal/d; NV: 2,628 ± 632 kcal/d; p = 0.

A second objective was to evaluate if additional input of specific food items on the existing potential renal acid load (PRAL) list was necessary for the comparison of the two dietary patterns. Thirty vegetarians between the age of 18 and 30 years were matched for sex, age and BMI with 30 non-vegetarians.

Of 515 children followed annually from age 6 to 18 years, 59 males and 60 females were measured again at age 35. Early, average, and late maturity groups were established.

Results: Twenty-nine girls and 31 boys, with minimum 2 yr of track and field training practice, were recruited.

Aim: To investigate if predictability of adult adiposity is related to maturation status in youth.
Methods: Data of the longitudinal ''LEGS''-study (N = 550) from 6 to 18 years were used. At 35 years, 59 men and 60 women participated again.
The daily intake of food flavonoids was determined using a semiquantitative food frequency questionnaire (FFQ) and a 4-day food record (4DFR) in a group of 45 female Flemish dietitians. The subjects were asked to report their food intake three times: day 1 using the FFQ (FFQ1); between days 2 and 13 using a 4-day non-consecutive food diary (4DFR); and again using the FFQ on day 14 (FFQ2). The total flavonoid intakes (mean and standard deviation) as estimated with the different methods were: for FFQ1, 166.

A healthy lifestyle, such as regular physical activity and avoidance of harmful practices, such as smoking and heavy drinking, could also influence these positive health-related outcomes in vegetarians. This study reports BMI, smoking and drinking habits, engagement in physical activity, medication use and subjective health perception in a vegetarian population (women: n = 206, mean age 37.

This study was designed to assess average daily dietary intakes of energy in 82 vegetarian children (group A: 6- 9-y-old girls and 6-11-y-old boys), adolescents (group B: 10- 15-y-old girls and 12-17-y-old boys), and young adults (group C: 16-30-y-old females and 18-30-y-old males) and included determination of height and weight; triceps, suprailiac, and calf skinfold thicknesses; puberty ratings; and physical fitness. Dietary energy intake was lower than recommended values in all 3 groups. Height and weight did not differ significantly from the reference data except in group B, which had significantly lower heights and weights and lower body mass indexes (P<0.

Habitual physical activity (HPA) was studied in 30 boys and 34 girls aged 6-11 years. All the children performed a shuttle run test (SRT) to assess maximal heart frequency (fcmaxSRT) and to evaluate maximal oxygen uptake (VO2maxSRT). Heart rate (fc) was measured continuously from Monday to Sunday, using a heart rate counter.

The anthropometric Heath-Carter somatotypes, with a stature correction for endomorphy, were estimated at 1-year intervals. Mean somatotypes were most different between the earliest and oldest ages in both boys and girls.

The coach frequently relates to skills or technical movements in terms of their aesthetic appearance rather than their mechanical effectiveness. The force output of the elbow flexors appears to be a function of the forearm position.

These effects when tested, respectively, after 7 min in the presence and after 60 min in the absence of theophylline were, however, 7- and 5-fold lower than in lean controls. The alpha-adrenergic blocker phentolamine and adenosine deaminase (which destroys extracellular adenosine) did not restore a normal lipolytic response to epinephrine in the adipose tissue of ob/ob mice.

The velocity of the rowing boat appears to depend on the force which the athlete applies at the handle of the oar. Although force is generated by legs, upper body, and arms, the latter are the only limbs which actually transmit and apply the force against the oar. The force output of the arms seem to be a function of the forearm position used by the athlete while gripping the oar.
