Comparison of energy metabolism and muscular activity between sitting on a stability ball and office chairs: A pilot study

Stability balls (SB) are commonly used as substitutes for office chairs (OC) due to their potential benefits in preventing musculoskeletal issues. However, limited research has explored the specific impact of SB usage on energy expenditure (EE). This study investigated the effects of using various chairs, including SB, on energy metabolism, muscle activity, and subjective sensations during seated rest. Sixteen adults alternated randomly between four chair types, sitting on each for 10 min: OC with a backrest (OCcont), OC without a backrest, OC designed to promote proper posture, and SB. Expired gas and surface electromyogram (EMG) data were recorded. The integrated EMG (iEMG) was analyzed for two abdominal, two back, and two lower limb muscles. Oxygen consumption was significantly higher while sitting on SB (mean ± standard deviation, 13 ± 21 % net increase) compared to OCcont. The combined iEMG for all six muscles showed a notable increase while sitting on SB (54.9 ± 45.6 % net increase) versus OCcont, with rectus femoris activation being particularly prominent. These findings indicate that substituting a standard OC with an SB during office work induces small but significant physiological changes, potentially aiding in obesity and metabolic disorder prevention.

Shrimp are popular as food in Japan, but their contamination status is not well understood. In this study, 45 shrimp products (seven species) collected from eight locations in Japanese coastal waters and the South China Sea were analyzed for persistent organic pollutants (POPs) and naturally occurring halogenated contaminants (NHCs). The compounds with the highest mean concentration among shrimp species were endosulfans (4.0 ng g^-1 dry weight, 41% of the total concentration), followed by polychlorinated biphenyls (PCBs, 26%), chlordanes (CHLs, 11%), methoxy-polybrominated diphenyl ethers (MeO-BDEs, 10%) and heptachlorinated methylbipyrrole (Cl₇-MBP, 4%). Endosulfan concentrations were not correlated with the PCB and CHL concentrations, which suggested that these compounds had different sources and kinetics. Regional differences were observed in Sakura shrimp (Lucensosergia lucens), with higher concentrations of CHLs and Cl₇-MBP from Suruga Bay in Japan, whereas MeO-BDEs were dominant in the south coast of Taiwan. The median estimated daily intake (EDI) of endosulfans through shrimp consumption was 60 pg kg^-1 bw day^-1. The EDIs of all analytes were well below reference doses set by the United States Environmental Protection Agency, indicating that health risks were unlikely, even in 95th percentile scenarios. The profiles and concentrations of these contaminants in shrimp in Japan suggest that shrimp is a potential dietary source of POPs (e.g., α-endosulfan) and NHCs (e.g., 2'- MeO-BDE68), and can serve as bioindicators of contamination status for dietary intake in Japan.
