Body composition and nutrition of female athletes

Abstract

Background. The somatic features of the athletes' bodies partially determine their sporting level and are conditioned to a large extent by the state of nutrition. Objective. The aim of this paper is to present nutritional status and its correlation with the somatic determinants of training athletes and physical education students. Material and methods. This study involved 12 weightlifting players (subgroup-WL), 15 soccer players (subgroup-SP), 12 table tennis players (subgroup-TT) and 12 female students of physical education (subgroup-C). In all subjects, the age and somatic variables were recorded and the daily intake of energy, water, proteins, fats and carbohydrates was determined by 24-h dietary recalls. Results. Although the analysis of variance did not show significant differences in somatic variables and nutrition data, post hoc analysis showed significant differences between some subgroups in terms of age, BMI, fat content (BF), fat-free mass (FFM) and the amount of water, protein and carbohydrates consumed during the day. It was also shown that somatic variables correlated with relatively expressed amounts of energy, proteins and carbohydrates consumed in individual subgroups, as well as in the whole group formed from all subgroups of studied women. In addition, there were significant correlations between somatic variables and the total amount of water consumed in the whole group and the total amount of protein consumed in subgroup C (p<0.05), as well as the total amount of fat consumed in subgroup WL. Conclusions. In summary, it was found that the examined women used an abnormal hypoenergetic diet with too low carbohydrate content in which were more useful relative than absolute amounts of consumed proteins, fats and carbohydrates. In this unfavorable situation, dietary education of the respondents seems to be necessary. STRESZCZENIEWprowadzenie. Cechy somatyczne organizmu sportowca częściowo determinują jego poziom sportowy i są uwarunkowane w znacznym stopniu stanem odżywienia. Cel. Celem prezentowanej pracy jest przedstawienie stanu odżywienia i jego współzależności z somatycznymi uwarunkowaniami trenujących sportsmenek i studentek wychowania fizycznego. Materiał i metody. Badaniom poddano 12 zawodniczek podnoszących ciężary (podgrupa-WL), 15 piłkarek nożnych (podgrupa-FP), 12 tenisistek stołowych (podgrupa-TT) oraz 12 studentek wychowania fizyczngo (podgrupa-C). U wszystkich badanych zarejestrowano wiek i zmienne somatyczne oraz określono dobową ilość przyjmowanej energii, wody, białek, tłuszczów i węglowodanów z zastosowaniem techniki 24 h rejestracji wstecznej. Wyniki. Pomimo, że analiza wariancji nie wykazała istotnych różnic w zakresie zmiennych somatycznych i danych żywieniowych to w analizie post hoc wykazano występowanie istotnych różnic pomiędzy niektórymi podgrupami w zakresie: wieku, wskaźnika BMI, zawartości tłuszczu (BF), beztłuszczowej masy ciała (FFM) oraz ilości wody, białka i węglowodanów spożywanych w ciągu doby. Wykazano też, że zmienne somatyczne korelowały z względnie wyrażonymi ...

Dietary mistakes of Polish athletes in relation to the frequency of consuming foods recommended in the Swiss food pyramid for active people

“…Monitoring nutrition and nutritional status is the basic task of dietitians, implemented in cooperation with the coaching team, playing an important role in motivation and control, aiding the improvement of the nutritional behaviours of athletes [8,47]. The legitimacy of nutritional education among athletes should be pointed out, which was also claimed by other authors [37,50].…”

Body Composition and Physical Fitness Profiles of Elite Female Japanese Wrestlers Aged <12 Years until >20 Years

“…Compared to preceding studies that investigated adolescent female wrestlers [ 9 , 12 ], the present elite wrestlers demonstrated no outstanding features concerning the stature, the body mass, and the BMI ( Table 2 , stature: 151.9 ± 3.8 cm in LW and 161.9 ± 4.6 cm in HW, body mass: 47.2 ± 2.5 kg in LW and 61.6 ± 5.8 kg in HW, BMI: 20.5 ± 1.1 in LW and 23.5 ± 2.3 in HW). When compared with athletes other than wrestlers [ 14 , 26 , 27 , 28 , 29 ], the present wrestlers did not have particularly large BMI ( Table 2 ). Despite the importance of muscle development in wrestling, the present elite female wrestlers showed ordinary BMI, probably because competitive wrestling is conducted in a weight-class system.…”

Leaping through Hurdles: Adaptability among Female Athletes

“…Women face many hurdles to participating in sports, which prevent them from reaping the many benefits that can be gained [3]. Most problems faced by college female athletes while playing basketball were verbal aggression [4], sexual harassment [5], social adjustments [6], relationship with coaches [7,8], academics challenges [9], menstrual disorders [10], training and competition stresses [11], and body composition [12]. Student-athletes were required to have careful balancing of stress and recovery for optimum adaptation with all the demands of additional requirements of an academic program [13].…”
