Abstract
OBJECTIVE To estimate the dose-response associations between non-occupational physical activity and several chronic disease and mortality outcomes in the general adult population. DESIGN Systematic review and cohort-level dose-response meta-analysis. DATA SOURCES PubMed, Scopus, Web of Science and reference lists of published studies. ELIGIBILITY CRITERIA Prospective cohort studies with (1) general population samples >10 000 adults, (2) ≥3 physical activity categories, and (3) risk measures and CIs for all-cause mortality or incident total cardiovascular disease, coronary heart disease, stroke, heart failure, total cancer and site-specific cancers (head and neck, myeloid leukaemia, myeloma, gastric cardia, lung, liver, endometrium, colon, breast, bladder, rectum, oesophagus, prostate, kidney). RESULTS 196 articles were included, covering 94 cohorts with >30 million participants. The evidence base was largest for all-cause mortality (50 separate results; 163 415 543 person-years, 811 616 events), and incidence of cardiovascular disease (37 results; 28 884 209 person-years, 74 757 events) and cancer (31 results; 35 500 867 person-years, 185 870 events). In general, higher activity levels were associated with lower risk of all outcomes. Differences in risk were greater between 0 and 8.75 marginal metabolic equivalent of task-hours per week (mMET-hours/week) (equivalent to the recommended 150 min/week of moderate-to-vigorous aerobic physical activity), with smaller marginal differences in risk above this level to 17.5 mMET-hours/week, beyond which additional differences were small and uncertain. Associations were stronger for all-cause (relative risk (RR) at 8.75 mMET-hours/week: 0.69, 95% CI 0.65 to 0.73) and cardiovascular disease (RR at 8.75 mMET-hours/week: 0.71, 95% CI 0.66 to 0.77) mortality than for cancer mortality (RR at 8.75 mMET-hours/week: 0.85, 95% CI 0.81 to 0.89). If all insufficiently active individuals had achieved 8.75 mMET-hours/week, 15.7% (95% CI 13.1 to 18.2) of all premature deaths would have been averted. CONCLUSIONS Inverse non-linear dose-response associations suggest substantial protection against a range of chronic disease outcomes from small increases in non-occupational physical activity in inactive adults. PROSPERO registration number CRD42018095481.

Evaluation of pea/rice and amylopectin/chromium as an alternative protein source to improve muscle protein synthesis in rats. Eur J Nutr 2023; 62:2293-2302. [PMID: 37186279 DOI: 10.1007/s00394-023-03150-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2022] [Accepted: 04/13/2023] [Indexed: 05/17/2023]
Abstract
BACKGROUND A preclinical study reported that the combination of an amylopectin/chromium complex (ACr) of branched-chain amino acids (BCAA) significantly enhanced muscle protein synthesis (MPS). This study was conducted to determine the effects of the addition of ACr complex to a pea/rice (PR) protein on MPS, insulin, muslin levels, and the mTOR pathway in exercised rats. METHODS Twenty-four rats were divided into three groups: (i) exercise (Ex); (ii) Ex + PR 1:1 blend (0.465 g/kg BW); (iii) Ex + PR + ACr (0.155 g/kg BW). On the day of single-dose administration, after the animals were exercised at 26/m/min for 2 h, the supplement was given by oral gavage. The rats were injected with a bolus dose (250 mg/kg BW, 25 g/L) of deuterium-labeled phenylalanine to determine the protein fractional synthesis rate (FSR) one h after consuming the study product. RESULTS The combination of PR and ACr enhanced MPS by 42.55% compared to the Ex group, while Ex + PR alone increased MPS by 30.2% over the Ex group (p < 0.0001) in exercised rats. Ex + PR plus ACr significantly enhanced phosphorylation of mTOR and S6K1 (p < 0.0001), and 4E-BP1 (p < 0.001) compared to the Ex (p < 0.0001). PR to ACr also significantly increased insulin and musclin levels (p < 0.0001) in exercised rats. Additionally, compared to Ex + PR alone, Ex + PR + ACr enhanced mTOR (p < 0.0001) and S6K1 (p < 0.0001) levels. CONCLUSION These data suggested that PR + ACr may provide an alternative to animal proteins for remodeling and repairing muscle by stimulating MPS and mTOR signaling pathways in post-exercised rats. More preclinical and clinical human studies on combining pea/rice and amylopectin/chromium complex are required.

Abstract
Affective responses and enjoyment of exercise mediate exercise adherence, but previous research findings have failed to examine nuances that may moderate this relationship. We examined the effects of exercise on affective and enjoyment responses during and post exercise through a systematic literature review and meta-regression analysis. We searched major databases up to July 9, 2020 for studies evaluating healthy adults' acute and chronic responses to exercise, using either of The Feeling Scale or Physical Activity Enjoyment Scales. We calculated effect size (ES) values of 20 unique studies (397 participants; 40% females) as standardized differences in the means and expressed them as Hedges' g, together with the 95% confidence interval (95%CI). Among acute studies examining affective responses, we found a greater positive effect post exercise for continuous training (CT) compared to high intensity interval training (HIIT) (g = -0.61; 95%CI = -1.11, -0.10; p < .018), but there was no significant difference between these modes for effects during exercise. Subgroup analyses revealed that moderate, and not high intensity, CT, compared to HIIT, resulted in significantly greater positive affective responses (g = -1.09; 95%CI = -1.88, -0.30; p < .006). In contrast, enjoyment was greater for HIIT, compared to CT (g = 0.75; 95%CI = 0.17, -1.13; p = .010), but CT intensity did not influence this result. Among chronic studies, there was greater enjoyment following HIIT compared to CT, but these studies were too few to permit meta-analysis. We concluded that an acute bout of moderate intensity CT is more pleasurable, when measured post exercise than HIIT, but enjoyment is greater following HIIT, perhaps due to an interaction between effort, discomfort, time efficiency and constantly changing stimuli.

Abstract
INTRODUCTION Ambient air pollution is a global environmental problem, which causes adverse health effects and premature deaths worldwide. Although regular exercise and physical activity have evident health benefits, the influence of long-term air pollution exposure during regular outdoor running has not been definitively clarified. METHODS AND ANALYSIS This study protocol describes the physiological and anthropometric perspectives of the 'Healthy Aging in Industrial Environment' Study - Programme 4 (4HAIE). The 4HAIE research project is intended to be a single-centre, prospective, longitudinal and multidisciplinary cohort study. The presented study protocol describes the cross-sectional measurements and analyses. Overall, 1500 adult participants (age 18-65 years), runners and inactive individuals, living in a high or low air-polluted area of the Czech Republic will be recruited. We will measure and analyse biomarkers of oxidative stress and inflammation in the blood, exercise capacity (graded exercise test and spiroergometry), blood pressure, lung function (spirometry), cardiac autonomic regulation and anthropometry (body composition). ETHICS AND DISSEMINATION The 4HAIE study protocol has already been approved by the Ethics Committee of the University of Ostrava (3/2018). A detailed participant information sheet will be provided to each individual prior to obtaining their written informed consent. The study poses little to no risk to participants. The findings of this study will be disseminated at regional and international conferences, in peer-reviewed journals and via social and broadcast media.

Abstract
Evidence supports exercise as a first-line option for many chronic diseases. Although recommendations suggest 150 to 300 minutes a week of moderate-intensity or 75 to 150 minutes a week of vigorous-intensity aerobic activity, replacing sedentary behaviors with light-intensity activities reduces risks of all-cause mortality, and cardiovascular disease (CVD) mortality and incidence of CVD and type 2 diabetes mellitus. Exercise has positive effects on brain function, cognition, and depressive symptoms. Based on such evidence, health care providers should incorporate evaluation of physical activity into patient care. Patients should be evaluated for readiness and ability to exercise and encouraged to increase activity level.

Abstract
PURPOSE Exercising benefits physical and mental health as well as longevity. However, the extent to which different types of exercise are differentially associated with the risk of mortality is less clear. This study examined whether 15 different types of exercise were uniquely associated with all-cause mortality in a nationally representative sample of noninstitutionalized American adults between 18 and 84 yr old. METHODS A total of 26,727 American adults in the National Health Interview Survey who reported their exercise type(s) in 1998 were prospectively followed for all-cause mortality through the end of 2015. We applied a series of discrete time logistic models to estimate odds ratios (OR) and 95% confidence intervals (CI) for all-cause mortality. RESULTS During 17 yr of follow-up, 4955 deaths occurred. After adjusting for total volume of other exercises and confounders (demographic factors, socioeconomic status, and health behaviors and status), walking, aerobics, stretching, weight lifting, and stair climbing were related to lower risks of mortality (OR ranged from 0.78 to 0.93). When adjusting for engagement in all exercise types and confounders, stretching (OR = 0.90, 95% CI = 0.83-0.97) and playing volleyball (OR = 0.53, 95% CI = 0.31-0.93) were uniquely associated with lower risks of mortality. CONCLUSION These findings suggest that some types of exercise have unique benefits for longevity, but most are indistinguishable in relation to longevity. Future studies should further investigate the unique contribution of specific exercises and the joint contribution of multiple exercises and how to promote greater exercise participation.

Abstract
PURPOSE OF REVIEW Robust epidemiological evidence exists that lifelong regular exercise contributes to longevity. The aim of this review is to discuss recent findings regarding, which dose and type of physical activity promotes a long healthy life, free of disease. RECENT FINDINGS Meeting the currently recommended amounts of leisure time physical aerobic activity of moderate intensity of at least 150 min/week provides most of the longevity benefit. However, a higher duration and intensity augments the beneficial effect on cardiovascular health and metabolism. Performing three to five times the recommended physical activity minimum reaches the maximal longevity benefit, that can be achieved. Although it is not dangerous to perform even higher amounts of exercise, the benefit may decrease. A high maximal oxygen uptake in mid-life is a strong marker of longevity, whereas muscle mass is a critical prognostic factor in aging and cancer. SUMMARY Exercise training above the public health recommendations provides additional benefits regarding disease protection and longevity. Endurance exercise, including high-intensity training to improve cardiorespiratory fitness promotes longevity and slows down aging. Strength training should be added to slow down loss of muscle mass, associated with aging and disease.
