We evaluated the acute effects of yoga compared to cycling on glucose change and variability, and the occurrence of hypoglycemia in adults with type 1 diabetes. Fifteen participants performed 50 min ...of cycling or yoga. Glucose values were collected before and after exercise. Coefficient of variation (CV) and hypoglycemic episodes were evaluated from the start up to 12 h after exercise. Cycling and yoga significantly reduced glucose values during exercise, and CV was lower after yoga. One hypoglycemic episode occurred with yoga and seven with cycling. Yoga is a safe exercise that acutely reduces glucose values, but with lower risk of hypoglycemia compared to cycling.

Two reviewers conducted all review stages independently. Selected data were pooled using random-effects meta-analysis.The included studies evaluated the relationship between aerobic exercise and depression at various time points among young individuals, and provided corresponding mean ± SD values. Depression diagnosis in the selected studies was conducted using the Depression Correlation Scale.MAIN OUTCOMES AND MEASURESThe included studies evaluated the relationship between aerobic exercise and depression at various time points among young individuals, and provided corresponding mean ± SD values. Depression diagnosis in the selected studies was conducted using the Depression Correlation Scale.After screening 2296 articles, 163 articles were selected for full-text review, and 8 of those were further reviewed. Ultimately, 12 studies, involving 658 individuals, were included in the meta-analysis. The results of the meta-analysis indicated that aerobic exercise could effectively improve depression in young people (d = -1.33, 95%CI: -1.78 ~ -0.87, P < 0.05). Subgroup analysis demonstrated that aerobic exercise was beneficial for both depression (d = -2.68, 95%CI: -3.87 ~ -1.48, P < 0.05) and non-depression (d = -0.85, 95%CI: -1.20 ~ -0.51, P < 0.05) conditions, as well as for low intensity (d = -0.93, 95%CI: -1.29 ~ 0.58, P < 0.05) and moderate intensity (d = -2.08,95%CI:-2.88 ~ -1.27, P < 0.05) exercises. Additionally, aerobic exercise was found to significantly alleviate depression in young people when performed for 40 min or less (d = -2.00,95%CI: -2.96 ~ -1.04, P < 0.05), whereas durations exceeding 40 min showed a lesser effect (d = -0.85,95%CI:-1.47 ~ -0.24, P < 0.05). Furthermore, the duration-based analysis revealed that aerobic exercise improved depression levels in young people regardless of duration, whether it was for less than 6 weeks (d = -1.27,95%CI: 2.12 ~ 0.14, P < 0.05), 6 to 11 weeks (d = 1.55, 95% CI: 2.16 ~ 0.94, P < 0.05), or more than 12 weeks (d = 1.00, 95% CI: -1.76 ~ -0.24,P < 0.05). Overall, these findings suggest that aerobic exercise is a promising intervention for alleviating depression in young individuals.RESULTSAfter screening 2296 articles, 163 articles were selected for full-text review, and 8 of those were further reviewed.

Overall, these findings suggest that aerobic exercise is a promising intervention for alleviating depression in young individuals.Both short (less than 40 min) and long (more than 40 min) periods of aerobic exercise were effective in improving depressive symptoms. However, the optimal duration of aerobic exercise may vary depending on the specific population and individual factors studied, such as age, health status, and exercise tolerance. Therefore, this study concluded that the most effective exercise regimen, 40 min of moderate-intensity aerobic exercise three times a week for 6 to 11 weeks, showed more significant improvement in depression indicators in individuals with depressive symptoms.CONCLUSIONSBoth short (less than 40 min) and long (more than 40 min) periods of aerobic exercise were effective in improving depressive symptoms.

Dyspnea, a prevalent and debilitating symptom in patients with advanced lung cancer, negatively affects symptom burden and prognosis. Physical activity has emerged as a promising non-pharmacological ...intervention for managing dyspnea.
This study compared the effectiveness of two widely-recognized physical activity modalities, namely Tai Chi (TC) and aerobic exercise (AE) for treating dyspnea in patients with advanced lung cancer.
Patients with advanced lung cancer (n=226) were randomized into TC, AE, or control groups. There was no baseline dyspnea requirement for patients. The AE group received two 60-minute supervised sessions and home-based exercises per month, the TC group received 60-minute sessions twice weekly, and the control group received exercise guidelines for 16 weeks. The primary outcome (sleep quality) of the study has been previously reported. In this secondary analysis, we focused on dyspnea outcomes, including overall and lung cancer-specific dyspnea. Assessments were conducted at baseline (T0), 16 weeks (T1), and one year (T2).
Compared to the control group, TC significantly improved overall dyspnea at T1 (between-group difference, −8.69; P=0.03) and T2 (between-group difference, −11.45; P=0.01), but not AE. Both AE (between-group difference, −11.04; P=0.01) and TC (between-group difference, −14.19; P<0.001) significantly alleviated lung cancer-specific dyspnea at T2 compared with the control group.
Both TC and AE alleviate dyspnea severity in patients with advanced lung cancer, and continuous exercise can yield substantial improvements. Due to its multi-component nature, Tai Chi has a greater effect on dyspnea.
The novel coronavirus disease 2019 (COVID-19) seems to be having a major impact on physical activity behaviours globally. The pandemic has forced many people around the world to stay at home and ...self-isolate for a period of time. WHO recommends 60 min/day of moderate-to-vigorous physical activity for 6-17-yr-olds, and 75 min/wk of vigorous or 150 min/wk of moderate physical activity for adults and elderly, including 3 and 2 days/wk, respectively, with muscle and bone strengthening. Practical recommendations for staying active at home, with aerobic exercise training on a bike or rowing ergometer, bodyweight training, dance and active video gaming, can aid to counteract the detrimental physical and mental side-effects of the COVID-19 protective lifestyle regulations. This commentary provides useful information on home-based physical activity for sedentary people across the lifespan, including children and adolescence, that can be undertaken during the present pandemic or other outbreaks of infectious disease.
The health benefits of regular physical activity and aerobic exercise are undisputed in the literature. The present series of pilot studies had two major objectives: (a) examine mental health, ...well-being, and regular physical activity of university students and (b) explore the potential health benefits of short-term aerobic exercise on university students in an online and a laboratory study. Mental health and well-being were measured before (Time 1, T1) and after (Time 2, T2) a 6 week (online study) and 2 week (laboratory study) low- to moderate-intensity aerobic exercise intervention. Mental health and well-being were assessed using standardized self-report measures of depression, anxiety, positive and negative affect, perceived stress and coping strategies, body dissatisfaction, and quality of life. The effects of the aerobic exercise were compared to a cognitive non-exercise control condition (online study), motor coordination exercise (laboratory study), and a waiting list (online and laboratory). A total of 185 university students were recruited from German universities at T1. Further, 74 (women: n = 67) students completed the 6-week intervention. Similarly, 32 (women: n = 30) participants completed the 2 week intervention (laboratory study). At T1, 36.6% of the students (women and men) reported experiencing depressive symptoms. 41.83% of them (women and men) had high levels of state anxiety. All the students reported experiencing stress (e.g., due to uncertainty related to factors such as their finances, job, and social relationships). At T1, regular physical activity was negatively correlated with self-reported depression, anxiety, and perceived psychosomatic stress and positively correlated with quality of life and positive affect. Among women, cardiovascular fitness (operationalized as resting heart rate variability) was negatively correlated with self-reported anxiety (state) and depression at T1 (laboratory study). The 6 week aerobic exercise intervention resulted in significant improvements in self-reported depression, overall perceived stress, and perceived stress due to uncertainty. The present results confirm that there is a relationship between regular physical activity, cardiovascular fitness, mental health, and well-being among university students. They support the hypothesis that short-term aerobic exercise interventions can act as buffer against depression and perceived stress in university students after 6 weeks of aerobic exercise of low to moderate intensity.
Aerobic exercise improves cognitive and motor function by inducing neural changes detected using molecular, cellular, and systems level neuroscience techniques. This review unifies the knowledge ...gained across various neuroscience techniques to provide a comprehensive profile of the neural mechanisms that mediate exercise-induced neuroplasticity. Using a model of exercise-induced neuroplasticity, this review emphasizes the sequence of neural events that accompany exercise, and ultimately promote changes in human performance. This is achieved by differentiating between neuroplasticity induced by acute versus chronic aerobic exercise. Furthermore, this review emphasizes experimental considerations that influence the opportunity to observe exercise-induced neuroplasticity in humans. These include modifiable factors associated with the exercise intervention and nonmodifiable factors such as biological sex, ovarian hormones, genetic variations, and fitness level. To maximize the beneficial effects of exercise in health, disease, and following injury, future research should continue to explore the mechanisms that mediate exercise-induced neuroplasticity. This review identifies some fundamental gaps in knowledge that may serve to guide future research in this area.
•Aerobic and resistance exercise typically lead to hypoalgesia in pain-free adults.•Exercise may lead to hypoalgesia or hyperalgesia in people with chronic pain.•Several different factors may ...influence the effect of exercise on pain.
Exercise is considered an important component of effective chronic pain management and it is well-established that long-term exercise training provides pain relief. In healthy, pain-free populations, a single bout of aerobic or resistance exercise typically leads to exercise-induced hypoalgesia (EIH), a generalized reduction in pain and pain sensitivity that occurs during exercise and for some time afterward. In contrast, EIH is more variable in chronic pain populations and is more frequently impaired; with pain and pain sensitivity decreasing, remaining unchanged or, in some cases, even increasing in response to exercise. Pain exacerbation with exercise may be a major barrier to adherence, precipitating a cycle of physical inactivity that can lead to long-term worsening of both pain and disability. To optimize the therapeutic benefits of exercise, it is important to understand how EIH works, why it may be impaired in some people with chronic pain, and how this should be addressed in clinical practice. In this article, we provide an overview of EIH across different chronic pain conditions. We discuss possible biological mechanisms of EIH and the potential influence of sex and psychosocial factors, both in pain-free adults and, where possible, in individuals with chronic pain. The clinical implications of impaired EIH are discussed and recommendations are made for future research, including further exploration of individual differences in EIH, the relationship between exercise dose and EIH, the efficacy of combined treatments and the use of alternative measures to quantify EIH.
This article provides a contemporary review of the acute effects of exercise on pain and pain sensitivity, including in people with chronic pain conditions. Existing findings are critically reviewed, clinical implications are discussed, and recommendations are offered for future research.
Introduction: Exercise is one of the recommended factors to reduce mortality from all types of cancer, especially brain cancer. The purpose of this study was to investigate the changes in the ...expression of Paxillin and PTK2 genes in the brain tissue of rats with glioblastoma multiforme after aerobic exercise training. Materials and Methods: Twenty-four male Wistar rats were divided into three groups (n=8): Healthy control, brain tumor, and tumor + aerobic training (AT). Glioblastoma was injected into frontal cortex of rats' brain. The exercise group performed aerobic exercises on the treadmill for four weeks and three days per week at a speed of 18 meters per minute for 25 to 40 minutes. At the end, the rats were sacrificed and Paxillin and PTK2 genes of their brain tissue were analyzed by Real-time PCR method. Histological images with H&E method were also used to confirm the tumor. Results: The tumor group showed increased necrosis and brain tissue damage compared to the healthy control group. In addition, the tumor group showed a significant increase in the expression of Paxillin and PTK2 genes compared to the healthy control group (p<0.001). This was while doing aerobic exercise in animals with brain tumor caused a significant decrease in Paxillin and PTK2 compared to the tumor group (p<0.001). Conclusion: Performing aerobic exercise in animals with brain tumors can reduce tumor cell strength by reducing the expression of Paxillin and PTK2 genes (effective in the extracellular matrix). However, more studies are needed in this field.
Mazaher Habibnezhad , Babisan Askari , Saqqa Farajtabar Behrestaq , Asra Askari Background: This study investigated the impact of a 3-week detraining period, followed by 10 weeks of aerobic training, ...on the serum levels of osteocalcin and alkaline phosphatase (ALP) in asthmatic males. Methods: Thirty adult males with asthma were randomly divided into experimental and control groups. The experimental group engaged in a 10-week aerobic training program, which included running sessions 3 times per week for 30-60 minutes each, maintaining a target heart rate range of 55%-75% of their maximum heart rate (HRmax). In contrast, the control subjects did not participate in any exercise activities during the study period. Fasting blood samples were obtained at baseline, after aerobic training, and after detraining to measure the levels of osteocalcin and ALP in both groups. Results: The 10-week aerobic training program led to a significant increase in levels of osteocalcin and ALP in the experimental group, but following the detraining period, these variables returned to their pre-training levels. Conclusion: The effectiveness of continuous aerobic training on bone formation markers in asthmatic patients will disappear after a relatively short period of detraining. This evidence emphasizes the lack of stopping aerobic exercise in the presence of inhaled corticosteroids with the aim of improving bone metabolism in asthmatic patients.
