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.
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.
Objectives:
Exercise physiology is one of the leading branches of applied physiology. It is concerned with studies related to the effect of acute and chronic exercise on mental and physical health ...research in human subjects and animals. There are various methods of physical exercise which have been used in animal studies including rodents. However, the machines available for research purposes are sophisticated and expensive, which also requires an additional annual maintenance cost. The objective is to assemble an efficient, reliable, cost-effective, and humane motorized exercise wheel setup for the study of acute and chronic physical exercise in rodents.
Materials and Methods:
The motorized rodent exercise wheel was assembled using affordable locally available materials.
Results:
A cost-effective, efficient model for rodent exercise was built and the total cost of this setup was 32 USD or 2860 INR only.
Conclusion:
This cost-effective rodent exercise wheel works efficiently for the conduction of exercise-related studies in rodents.
Introduction: Cardiotrophin-1 (CT-1) is an interleukin-6-related cytokine with known hypertrophic and protective actions upon cardiac myocytes. The present study aimed to investigate the impact of 1- ...week aerobic exercise on serum levels of cardiotrophin-1 in female patients with hypertension.Methods: in this study, 35 old women aged 50 to 70 were randomly divided into two groups (15 controls and 15 controls). The exercise program included aerobic exercises conducted increasingly 3 times a week for 12 weeks. Before the exercise, and 24 hours after the last session, blood samples and the body composition were taken. Data were collected and analyzed using one-way ANCOVA and Tukey post hoc test at a significant level of P≤0/05.Results: According to the results, twelve weeks of exercise did not significantly affect CT-1 level.Conclusion: Overall, it seems that 12-week aerobic exercise has been beneficial in patients with hypertension and has been improving myocardial function; however, further studies are needed.
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.
Exercise offers several benefits in combating mood-related symptoms in humans. Participation in various types of physical activity improves brain and mental health. However, the different effects and ...mechanisms depending on the type of exercise on an individual's mood and brain remain unclear. This pilot trial aimed to reveal the feasibility of the effects of resistance and aerobic exercise on mood-related symptoms and explain the different patterns of brain waves.
This 15-week single-arm pre-test/post-test trial including 3 measurement periods was held in Seoul, Republic of Korea. Overall, 18 healthy participants aged 19–29 years were recruited. After 6 weeks of respective aerobic and resistance exercise, anxiety/depression-related questionnaire scores and electroencephalography (EEG) changes were measured (single blinded outcome assessment). Specifically, changes in frontal alpha asymmetry (FAA), absolute band power of beta waves, and theta waves were measured in the prefrontal and frontal regions, which play a critical role in regulating mood and cognition.
Resistance exercise resulted in a significant reduction in Beck Depression Inventory-II scores (p = 0.002, effect size = 0.76) while significant improvement was shown in Beck Anxiety Inventory scores (p = 0.01, effect size = 0.77) after aerobic exercise. In regarding EEG analysis, ten participants completed the assessment. After resistance exercise, there was a significant elevation in frontal beta waves (p = 0.01, effect size = 0.81). Aerobic exercise did not result in significant EEG changes. There were no adverse events related to study participation.
Our findings suggest that resistance and aerobic exercises may be feasible for the alleviation of mood-related symptoms and EEG activities. As our pilot trial has a small sample size and did not include a control group, future research that accurately reflects the effects of different types of exercises on mood symptoms and changes of EEG activities is required.
•Exercise has a positive effect in the alleviation of anxiety and depression.•30 healthy adults were recruited, 18 completed the full intervention, and 9 participated in the EEG analysis.•6 weeks of aerobic and resistance exercise resulted in medium to large effect size for improvements in mood and EEG changes.•A three-arm randomized control trial is necessary to compare the effects of different types of exercise.
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.
