Energy requirements can be estimated from resting energy expenditure (REE). However, little is known about factors influencing REE in Japanese female athletes. This study was performed to evaluate the relationship between REE and body composition in Japanese female athletes with a wide range of body sizes. Ninety-three athletes (age 20.3±1.2 y, height 162.8±6.4 cm, body weight (BW) 57.0±9.2 kg, fat-free mass (FFM) 45.4±6.2 kg) were classified into three groups according to BW: small-size (S) (n=

Low energy availability (EA) can impair physiological function in athletes. The purpose of this study was to investigate EA status, metabolic status, and bone metabolism with biochemical analysis in Korean male soccer players. Twelve male athletes (18-20 years) completed the study. Body composition and bone mineral density were measured using dual energy X-ray absorptiometry (DXA), while VO₂ max was determined by an incremental exercise test. Blood samples were taken for bone marker a

It has been reported that male athletes face increased risk for low energy availability and resulting health consequences similar to female athletes. The present study aimed to reveal the energy status of Japanese male runners and to examine the association between energy deficiency and physiological characteristics such as energy metabolism, bone health, and hormonal status. Six male collegiate long-distance runners during a training season participated in this study. Energy intake (EI) was ass

Metabolic suppression due to relative energy deficiency can cause various physiological impairments in athletes. The purpose of this study was to evaluate within-day energy balance (WDEB) and the ratio between measured and predicted resting energy expenditure (REE_ratio) and to investigate the relationships between the markers of metabolic suppression. Ten male collegiate soccer players completed a 7-day food diary, physical activity, and heart rate records during the training and rest

An intensive consecutive high-volume training camp may induce appetite loss in athletes. Therefore, this study aimed to investigate the changes in stress and appetite responses in male power-trained athletes during an intensive training camp. The measurements at Day 2 and at the end of a 9-day intensive training camp (Camp1 and Camp2, respectively) were compared with those of the resting period (Rest) and the regular training period (Regular; n = 13). The stress state was assessed based on plasm

競技特性の異なる女性スポーツ選手の安静時代謝量（Resting energy expenditure: REE）を比較することを目的として，81名の女子選手（年齢：20.3±1.2歳，身長：162.3±6.5cm，体重：56.4±7.9kg，体脂肪率：20.4±5.1％，除脂肪量（LBM）：44.8±5.0kg）および同年代の運動習慣のない女子大学生16名を対象として測定を行った。選手群は競技特性により持久系21名，瞬発系40名及び球技系20名の3つの競技特性群に分類した。REEは間接法にて測定し，身体組成は空気置換法にて測定した。1日当たり，体重あたり，LBMあたりのいずれの単位においても全ての群間で有意差は認められなかった。REEと体重およびLBMとの間には，選手群,コントロール群ともに有意な正の相関関係が認められた。競技特性群別のREEとLBMとの回帰式の傾きと切片には差は認められなかった。また，重回帰分析の結果，選手群のREEの説明因子としてLBMとT3が抽出され，LBMで45.0％，T3を加えることにより50.3％が説明できることが明らかとなった。以上より，競技特性の異なるス

Japanese female collegiate athletes failed to meet energy and nutrient recommendations; BMI and EI were significantly associated with stress fractures, a diet that includes an appropriate amount of energy is essential.

The aim of the present study was to clarify the influence of inulin and lactulose-fortified prebiotic food intakes on bone metabolism turnover among Japanese female athletes. The participants included 29 female athletes aged 18-25 years. They were requested to consume their habitual foods or drinks with one pack of prebiotic food every day for 12 weeks. Dietary intake, training time, body composition, blood sample, and fecal microbiota were assessed during this intervention period. Body composit

The basal metabolic rate (BMR) of female endurance athletes was evaluated in relation to the body composition and nutritional status. The subjects were 16 long-distance runners mean (SD) age: 19.1 (2.4) y, height: 160.2 (4.5) cm, weight: 48.2 (4.1) kg, body fat: 16.6 (3.3)%, 8 rowers ((20.6) (1.2) y, 162.8 (3.2) cm, 57.0 (5.6) kg, 18.2 (4.6)%), and 19 sedentary non-athletic controls (20.1 (0.7) y, 159.7 (5.1) cm, 51.0 (5.2) kg, 23.7 (2.8)%). All subjects were eumenorrheic (estradiol: 47.2 (35.9)

For athletes to gain body mass, especially muscle, an increase in energy consumption is necessary. To increase their energy intake, many athletes consume more meals, including supplementary meals or snacks. However, the influence of meal frequency on changes in body composition and appetite is unclear. The aim of this study was to determine the effect of meal frequency on changes in body composition and appetite during weight gain in athletes through a well-controlled dietary intervention. Ten m

Athletes experience high total energy expenditure; therefore, it is important to understand the characteristics of the components contributing to this expenditure. To date, few studies have examined particularly the volume and activity intensity of non-exercise activity thermogenesis (NEAT) in athletes compared to non-athletes under real-life conditions. This study aimed to determine the volume and intensity of NEAT in collegiate athletes. Highly trained Japanese male collegiate athletes (<i>n</

The aim of the present study was to examine the validation of prediction equation of basal metabolic rate (BMR) in Japanese female athletes. The study population consisted of 122 Japanese female athletes (age 20.2 ± 1.3 years, height 162.5 ± 6.3 cm, body weight (BW) 57.4 ± 7.7 kg, and fat-free mass (FFM) 45.5 ± 5.1 kg). Body composition was estimated by using air displacement plethysmography (BOD POD System). BMR was measured by indirect calorimetry using dougras bag tequnique, and predicted BMR
