Background: The aim of the present study was to investigate the muscular and cardiorespiratory adaptations of two water-based training programs in older women.
Methods: Volunteers were divided between a water-based aerobic training (WBA; N.=13), water-based combined training (WBC; N.=11) or an active control group (CG; N.=9) and those assigned to WBA and WBC exercised twice a week for 12 weeks. All outcomes of interest were assessed prior and after the intervention. The data were analyzed using Generalized Estimating Equations (GEE), and Bonferroni post-hoc test (α=0.05). Aerobic training was performed at the percentage of the heart rate corresponding to the anaerobic threshold and resistance training during WBC was performed with sets at maximal effort.
Results: Improvements were observed for the maximal knee extension dynamic strength (1RM) and oxygen uptake (VO
Conclusions: These results suggest that WBA, WBC and CG are effective to improve cardiorespiratory fitness, however, only water-based training programs (WBA and WBC) appear capable of improving the maximal strength of the lower limbs.

This study aimed to investigate the effects of two water-based training programs (aerobic and combined) and a non-periodized physical activity program on functional capacity and quality of life (QoL) of elderly women. Forty-one elderly female volunteers (65 ± 4 years) were divided into three groups: aerobic training group (WBA, n = 13), combined training (sequence: resistance/aerobic; WBC; n = 11) and a control group of non-periodized physical activity program (CG, n = 9). The participants performed the water-based trainings twice a week for 12 weeks.

Article Synopsis
- Pig husbandry involves intensive breeding, exposing piglets to stress from events like early weaning and mixing, which can weaken their immune systems and lead to increased antibiotic use.
- This study focused on how acute social stress affects the immune response of piglets selected for their differing HPA axis activity, showing stressed piglets had higher cortisol levels and altered immune responses.
- Findings suggest that high-responding piglets may have better immune responses and resistance to pathogens compared to low-responders, indicating that selecting for robustness could improve overall pig health in stressful environments.

Inhalation exposure to particulate matter containing endotoxin (or lipopolysaccharide (LPS)) occurs in a variety of occupations. Nasal lavage and induced sputum have been used to evaluate lung inflammation resulting from such exposures. Whole blood assay (WBA) measures cytokine production of leukocytes after ex vivo stimulation with LPS.
