AI Article Synopsis
- The study investigated how intraocular pressure (IOP) responds to a maximal running test and during a 30-minute recovery in healthy women.
- During the exercise, IOP varied significantly among individuals and was influenced by baseline IOP and initial heart rate.
- Results indicated that while IOP didn't change significantly overall from rest to post-exercise, those with lower baseline IOP experienced a more noticeable increase compared to those with higher baseline levels.
Article Abstract
Significance: The main aim of this study was to determine the intraocular pressure (IOP) response to maximal incremental running test during 30 minutes of recovery. Exhaustive exercise induced a highly individually variable IOP response, which was related to its initial value and the initial heart rate.
Purpose: The purpose of the study was to analyzed the IOP response to a maximal incremental running test in healthy women during a 30-minute recovery period. Secondarily, the study attempted to determine if the IOP was dependent on its baseline, maximal oxygen uptake, initial heart rate, and autonomic nervous system regulation.
Methods: Twenty-four healthy women between the ages of 19 and 30 years were recruited for the study. Initial IOP (baseline), heart rate, and autonomic nervous system regulation were measured after 30 minutes of rest. Each subject then underwent an incremental running test on a treadmill to reach the maximal physical activity and to determine physical fitness based on maximal oxygen uptake. Intraocular pressure and autonomic nervous system activity were measured immediately after completion of the physical activity during a 30-minute recovery period in the supine position.
Results: The IOP variability increased markedly after the exercise up to 1.7-fold of the resting state. The IOP before and after exercise did not differ significantly; however, the lower baseline revealed a significant increase in comparison with the higher baseline. The time course of the IOP changes was significantly influenced by the initial heart rate. All other effects, interactions, and correlations were insignificant.
Conclusions: The IOP response after maximal exercise was highly dependent on the individual. The IOP seems to be slightly increasing with a significant dependence on its resting baseline and initial heart rate.

Pregnancy issues such as gestational hypertension, preeclampsia, and gestational diabetes mellitus (GDM) are significant contributors to long-term cardiovascular diseases (CVDs) in women. Recent research has proved the impact of exercise on improving cardiovascular outcomes, particularly in women with pregnancy-related disorders. This review explores the outcomes of various exercise interventions on cardiovascular health in pregnant women.

Background: The UK's National Health Service Test and Trace (NHSTT) program aimed to provide the most effective and accessible SARS-CoV-2 testing approach possible. Early user feedback indicated that there were accessibility issues associated with throat swabbing. We report the results of service evaluations performed by NHSTT to assess the effectiveness and user acceptance of swabbing approaches, as well as qualitative findings of user experiences from research reports, surveys, and incident reports.

Background: Studies on rest durations during high-intensity interval training (HIIT) often compare fixed and self-selected (SS) rest allocation approaches. Frequently, the rest duration under SS conditions is unlimited, leading to inconsistent total rest durations compared to fixed rest conditions. To address this limitation, we recently compared fixed and SS rest conditions during cycling HIIT sessions, while keeping the total rest duration equivalent.

Purpose: This study aimed to investigate the impact of a 6-week upper-body plyometric-training (PT) program with varying volumes on the immunoendocrine, physiological parameters, and physical performance adaptations in male volleyball players.
Methods: Twenty-four trained college players were randomly allocated into 3 groups with 8 participants. Each group performed 5 exercises at maximal effort with differences in volume: low (3 sets of 7 repetitions), moderate (3 sets of 10 repetitions), and high (3 sets of 13 repetitions).
Real-time detection of somatostatin release from single islets reveals hypersecretion in type 2 diabetes.
Acta Physiol (Oxf)

Department of Medical Cell Biology, Uppsala University, Uppsala, Sweden.
Aim: Somatostatin from pancreatic δ-cells is a paracrine regulator of insulin and glucagon secretion, but the release kinetics and whether secretion is altered in diabetes is unclear. This study aimed to improve understanding of somatostatin secretion by developing a tool for real-time detection of somatostatin release from individual pancreatic islets.
Methods: Reporter cells responding to somatostatin with cytoplasmic Ca concentration ([Ca]) changes were generated by co-expressing somatostatin receptor SSTR2, the G-protein Gα15 and a fluorescent Ca sensor in HeLa cells.
