Determining total energy expenditure in 3-6-year-old Japanese pre-school children using the doubly labeled water method.

The doubly labeled water (DLW, HO) method for calculating the total production of CO over several days is currently considered to be the most accurate technique for the measurement of total energy expenditure (TEE), and the results obtained using this method have been used to review energy requirements. Presently, there is limited data available on TEE in Japanese children. The objective of this study was to assess the TEE in pre-school Japanese children using the DLW method.

Effects of high-intensity swimming training on the bones of ovariectomized rats.

Purpose: This study was performed to assess the effects of high-intensity intermittent swimming training(HIT) on bone in ovariectomized rats.

Methods: Six-week-old female Sprague-Dawley rats were randomly assigned to either sham operation or bilateral ovariectomy. After surgery, they were divided into the following four groups: 1) sham-operated sedentary (S), 2) sham-operated exercise training (SE), 3) OVX sedentary (O), 4) OVX exercise training (OE) 5) OVX given 17β-estradiol (OE2) and 6) OVX exercise training and given 17β-estradiol (OEE).

Effects of skim milk powder intake and treadmill training exercise on renal, bone and metabolic parameters in aged obese rats.

Purpose: we aim to examine whether adding exercise has impact on obesity prevention and bone metabolism in senior rats, to which dietary obesity was induced through skim milk intake.

Methods: We used 47, 14-week old Sprague -Dawley (SD) female rats (CLEA Japan, Inc.).

Relationship between performance test and body composition/physical strength characteristic in sprint canoe and kayak paddlers.

Objective: Canoe sprint is divided into canoe and kayak. The difference between the two competitions is in physical performance. The aim of the present study was to compare and investigate the relationship between physical characteristics and fitness between the two canoe sprint competitors.

The ACTN3 R577X polymorphism is associated with muscle power in male Japanese athletes.

In this study, we investigated whether the ACTN3 R577X polymorphism is associated with muscular power in Japanese collegiate athletes by analyzing the mean and peak power results of a 30-second Wingate anaerobic test (WAnT) with respect to the ACTN3 R577X genotype in 253 Japanese athletes (144 men and 109 women). Each athlete performed a 30-second WAnT with a resistance equal to 7.5% of his or her body weight.

Higher frequency of the ACTN3 R allele + ACE DD genotype in Japanese elite wrestlers.

In this study, the authors investigated the association between the ACTN3 and angiotensin-converting enzyme (ACE) genotypes and the performance of 135 Japanese elite male wrestlers. Fifty-two wrestlers had participated in world championships, including the Olympic Games, or had placed first in Japanese national championships and were classified as "international." The remaining 83 wrestlers were classified as "national.

The ACTN3 XX genotype's underrepresentation in Japanese elite wrestlers.

Purpose: To examine the relationship between ACTN3 polymorphisms and level of athletic performance in Japanese wrestlers.

Methods: The control group consisted of 243 healthy Japanese individuals. The authors divided 135 wrestlers into 3 groups based on their results in national or international competitions.

Opuntia humifusa supplementation increased bone density by regulating parathyroid hormone and osteocalcin in male growing rats.

We investigated the effect of Opuntia humifusa (O. humifusa) supplementation on bone density and related hormone secretion in growing male rats. Sixteen six-week-old male Sprague-Dawley rats were randomly divided into two groups; control diet group (CG, n = 8), and experimental diet group (EG, n = 8).

Effect of the moderate exercise on performance in upper/lower limb during long term bed rest.

The purpose of this study was to investigate that considers the influence of the moderate exercise has on the upper limbs and the legs during 21 days head down bed rest. Therefore motor evoked potential (MEP) induced by transcranial magnetic stimulation (TMS) in lower leg muscles of four healthy subjects were investigated before/after and during bed rest. There were no significant differences statistically between soleus MEPs before and after bed rest in all subjects.

Effects of habitual chitosan intake on bone mass, bone-related metabolic markers and duodenum CaBP D9K mRNA in ovariectomized SHRSP rats.

We have demonstrated that the habitual intake of chitosan can decrease bone mass in ovariectomized (OVX) SHRSP rats fed a low-Ca diet (0.1%). In the present study, we examined both the etiology of bone loss induced by dietary chitosan and the preventive effect of vitamin C supplementation.
