Abstract

Physical inactivity is a significant risk factor for numerous chronic diseases, including cardiovascular conditions and type 2 diabetes, particularly in aging populations. Resistance training has been shown to reduce systemic inflammation and preserve muscle mass, which can mitigate the impacts of aging. However, the regressive effects of detraining on older adults' health outcomes remain underexplored. This study aimed to investigate the effect of a three-month detraining period following a nine-month multicomponent training program on cardiorespiratory fitness, lipid profiles, glycemic control, and hemodynamic status in older women. Fifty-six Asian women aged 58–70 were divided into an experimental group (EG) and a control group (CG). The EG participated in a nine-month exercise program, which included cardiorespiratory, strength, balance, and flexibility training. After this, both groups underwent three months of detraining. The results showed that the EG experienced significant declines in body weight, BMI, and cardiorespiratory fitness following detraining, with adverse effects on lipid and glycemic profiles. The findings suggest that even a short period of detraining can lead to the loss of metabolic and functional benefits from long-term exercise, emphasizing the importance of maintaining regular physical activity to sustain health in aging populations.

Abstract

Background: The wound healing process post-extraction is expected to be quick, which can reduce the risk of complications and restore normal tissue function. A minimum oxygen supply needs to be met so that acceleration of the wound healing process can occur. Wound healing can be accelerated by continuous moderate-intensity exercise with increasing tissue oxygenation. Collagen requires oxygen in the procollagen formation process to support wound healing. Purpose: This study aimed to prove the role of continuous moderate-intensity exercise in increasing collagen density in the dental sockets of Wistar rats (Rattus norvegicus) after tooth extraction. Methods: Four groups of Wistar rats were created: control groups K1 (on day 3) and K2 (on day 7), and treatment groups K3 (on day 3) and K4 (on day 7). K1 and K2 were submerged in a bucket of water, and K3 and K4 received daily moderate-intensity exercise for a duration of two weeks. The rats' incisors were extracted on the day 15. Post-extraction collagen density was measured on day 3 (K1 and K3) and on day 7 (K2 and K4). The one-way ANOVA test and post-hoc Tukey test were used in the statistical analysis of the data. Results: There was a significant difference between all groups (p: 0.0001; p<0.05). Group K4 had a higher collagen density than the other groups. Conclusion: Continuous moderate-intensity exercise played a role in increasing the density of collagen in the rat tooth socket after tooth extraction.
