Summary: This study evaluated the impact of pulmonary rehabilitation on heart rate recovery (HRR) in individuals with asthma compared to those with COPD. The findings showed that individuals with asthma had a lower prevalence of slow HRR than those with COPD. However, exercise training significantly improved exercise capacity in both populations.

Summary: The increased cardiometabolic risk in breast cancer survivors is attributed to multiple mechanisms, including hormonal and immunological dysfunction as well as cardiac autonomic regulation. This study found that physical activity can improve cardiac autonomic regulation, metabolism, and psychological well-being in breast cancer survivors.

Summary: This study measured ECG signals of mouse fetuses to evaluate the development of heart rate and autonomic nervous activity at different stages, finding that fetal heart rate significantly increased at E18.5, accompanied by reduced parasympathetic activity. It suggests that parasympathetic activity rather than sympathetic activity affects fetal heart rate, and the decrease in parasympathetic activity towards the end of pregnancy could lead to the observed increase in fetal heart rate.

Summary: The relationship between the robustness of HRV derived by linear and nonlinear methods to the required minimum data lengths has yet to be well understood. This study found that most HRV measures can be adequately computed by small data sizes, while some may require longer data lengths. Determining the optimal minimum data sizes can potentially improve efficiency and save time and effort for both patients and medical care providers.

Summary: The study found that temperature variability is negatively associated with heart rate variability, especially on the same day. The exposure-response relationships were almost linear for most parameters. The increase in temperature variability is significantly associated with the decrease in heart rate variability, with females being more affected.

Summary: Exercise is an important determinant of a healthy lifestyle, especially in childhood, and serves as a preventive tool. However, obesity and hypertension rates are increasing in children, increasing the risk for cardiovascular and metabolic diseases in adulthood. This feasibility study examined a group of obese children before and after a 12-week online exercise training program, dividing participants into two groups based on exercise volume. Improvements in structured exercise volume were associated with reduced arterial pressure and improved autonomic and metabolic control.

Summary: This study investigated the cardiovascular response to exercise in individuals with prior symptomatic (S) or asymptomatic (AS) COVID-19 infections. The results showed that the S group had significantly lower heart rate variability and blood pressure variability, indicating that a previous symptomatic infection may affect heart rate and blood pressure regulation during exercise.

Summary: In this study, the impact of manipulating exhalation to inhalation ratio (E:I) on heart rate variability (HRV) was examined. The findings suggest that a longer exhalation relative to inhalation, without altering breathing rate, acutely increased HRV metrics, pointing towards an enhancement of cardiac vagal tone.

Summary: The interpretation of FHR patterns is crucial for monitoring fetal well-being during labor, and changes in FHR variability (FHRV) have been considered an indication of fetal compromise. However, there is a lack of systematic evidence to support this observation. This review examines the potential pathways controlling FHRV during labor-like hypoxia and suggests that the parasympathetic system becomes the sole regulator of FHRV once FHR decelerations occur.

Summary: The autonomic nervous system (ANS) can modulate the oscillation of electrocardiogram segments and their intervals, including the myocardial repolarization phase. This study investigates the influence of head-up/-down tilt on ECG segments, suggesting that cardiopulmonary postural reflexes can modulate ECG interval oscillations. T wave amplitude decreases during head-up tilt and correlates with left ventricular end-systolic volume. Head-up/-down tilt acutely modifies the autonomic nervous system balance through deactivation of cardiopulmonary reflexes.

Summary: This study investigates the proportion of overweight/obesity in young adults with PFP and explores the association of BMI, body fat, and lean mass with functional capacity and hip and knee strength in this population. The results show that more than one-third of PFP patients are overweight/obese, and higher BMI, body fat, and lower lean mass are associated with poorer functional capacity and strength. Thus, considering these factors is important in assessing and managing PFP in young people.

Summary: This study compared body mass index (BMI), body fat, and skeletal muscle mass in individuals with patellofemoral pain (PFP) and pain-free individuals. The results showed that women with PFP had higher BMI, body fat, and lower skeletal muscle mass compared to pain-free women. However, there were no significant differences in these measures between men with PFP and their pain-free counterparts. Therefore, BMI and body composition should be taken into consideration when evaluating and managing individuals with PFP, especially in women.

Summary: This study conducted a systematic review and meta-analysis to determine the efficacy of cold-water immersion (CWI) on muscle soreness management. The results showed that CWI was superior to control in reducing muscle soreness, regardless of water temperature and protocol. Short and medium immersion times and endurance exercises yielded positive effects, while longer immersions time did not.

Summary: Pregnancy complicated by obesity leads to negative gestational and neonatal outcomes, as well as a decrease in CD4+ T-lymphocytes. This study investigates how maternal obesity affects colostrum lymphocytes and the intracellular mechanisms of lymphocyte modulation. The results show that maternal obesity reduces T-lymphocytes and TCD4+ in colostrum and inhibits cell proliferation, but these effects can be restored by hormones such as leptin, adiponectin, and melatonin.

Summary: The aim of this study was to analyze the autonomic modulation of heart rate in hypertensive elderly individuals during and after a session of aerobic exercise, and to compare it with elderly individuals without cardiovascular or metabolic disease. The results showed that after exercise, elderly individuals without cardiovascular and metabolic diseases had a decrease in parasympathetic modulation and global heart rate variability, but it restored within 30 minutes of post-exercise recovery. We concluded that there was no difference in autonomic modulation and global heart rate variability between elderly individuals without cardiovascular and metabolic diseases and hypertensive individuals after a bout of aerobic exercise.

Summary: This study aims to investigate the effects of adding an 8-week online mindfulness-based intervention (MBI) program to exercise therapy and patient education on clinical and psychological factors for people with patellofemoral pain (PFP). The study will recruit 62 participants and randomize them into two treatment groups, with one group receiving the MBI component in addition to exercise therapy and education. The results of this study have the potential to provide new directions for the treatment of PFP.

Summary: This study aims to investigate the group-by-time changes in patellofemoral pain (PFP) symptoms, biomechanical, muscle function, pain processing, and psychological features over a minimum of 15 months follow-up, as well as the associations between these changes and self-reported pain, physical performance measures, self-reported function, health-related quality of life (HRQOL), and physical activity level. Generalized linear mixed model (GLMM) and linear regression models will be used to analyze the data. This study is important for understanding the predictors of long-term outcome and identifying targets for interventions in PFP.
