Research paper thumbnail of Browning formation markers of subcutaneous adipose tissue in relation to resting energy expenditure, physical activity and diet in humans

We examined the relationship between REE, physical activity (PA) participation and diet with browning formation markers of subcutaneous WAT in healthy men. Materials and methods We assessed REE, diet and body composition of 32 healthy men [age (years): 36.06 ± 7.36, body mass index (BMI): 27.06 ± 4.62 (kg/m2)]. Participants also underwent measurements of PA [metabolic equivalent (MET)-min/week] using the International Physical Activity Questionnaire (IPAQ), while they undertook a subcutaneous fat biopsy from the abdominal region to assess the mRNA expressions of uncoupling protein 1 (UCP1), peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α), peroxisome proliferator-activated receptor alpha (PPARα) and peroxisome proliferator-activated receptor gamma (PPAR...

Research paper thumbnail of Impact of vitamin D supplementation during a resistance training intervention on body composition, muscle function, and glucose tolerance in overweight and obese adults

Methods-Twenty-three overweight and obese (age: 26.1±4.7 y; BMI: 31.3±3.2 kg/m 2 ; 25hydroxyvitamin D: 19.3±7.2 ng/mL) adults were recruited for participation in a double-blind, placebo-controlled trial. Participants were randomly divided into vitamin D (VitD, 4000 IU/d; 5 female, 5 male) and placebo (PL; 7 female, 6 male) groups. Both groups completed 12 wks of resistance training. 25-hydroxyvitamin D, parathyroid hormone, body composition, and glucose tolerance were assessed at baseline and 12 wks. Muscle function (strength and power) was assessed at baseline, 4, 8, and 12 wks.

Methods: We used fingertip temperature (T f), forearm temperature minus T f (T For-f), rectal temperature (T re), and their changes across time (lag T) to estimate BF f. Ten participants (six male, four female) were randomly divided into ''model'' and ''validation'' groups. We employed a passive hot-cold water immersion protocol during which each participant's core temperature increased and decreased by 0.5°C above ⁄ below baseline during hot ⁄ cold conditions, respectively. A hierarchical multiple linear regression analysis was introduced to generate models using temperature indicators and lag T (independent variables) obtained from the model group to predict BF f (dependent variable). Results: Mean BF f (109.5 ± 158.2 PU) and predicted BF f (P-BF f) (111.4 ± 136.7 PU) in the model group calculated using the strongest (R 2 = 0.766, p < 0.001) prediction model [P-BF f = T f • 19.930 + lag4 T f • 74.766 + lag4 T re • 124.255-447.474] were similar (p = 0.6) and correlated (r = 0.880, p < 0.001). Autoregressive integrated moving average time-series analyses demonstrated a significant association between P-BF f and BF f (R 2 = 0.381; Ljung-Box statistic = 8.097; p < 0.001) in the validation group. Conclusions: We provide a model that predicts BF f via two practical temperature indicators that can be implemented in both clinical and field settings.
