Holistic physical exercise training improves physical literacy among physically inactive adults: a pilot intervention study
Background
Physical literacy (PL), given as a multidimensional construct, is considered a person’s capacity and commitment to a physically active lifestyle. We investigated the effect of a holistic physical exercise training on PL among physically inactive adults.
Methods
A non-randomised controlled study was conducted. Thirty-one physically inactive adults in the intervention group (IG; 81% females, 44 ± 16 years) participated in a holistic physical exercise training intervention once weekly for 15 weeks. A matched, non-exercising control group (CG) consisted of 30 physically inactive adults (80% female, 45 ± 11 years). PL, compliance and sociodemographic parameters were measured. PL was evaluated by a questionnaire, covering five domains: physical activity behaviour, attitude towards a physically active lifestyle, exercise motivation, knowledge and self-confidence/self-efficacy. Data were analysed using ANCOVA models, adjusted for age, gender and BMI at baseline.
Results
At post-training intervention, the IG showed significant improvements in PL (
p
= 0.001) and in the domains physical activity behaviour (
p
= 0.02) and exercise self-confidence/self-efficacy (p = 0.001), with no changes overserved for the CG regarding PL and those domains. No intervention effect were found for the other three domains, i.e. attitude, knowledge and motivation. Additionally, for the IG baseline BMI was identified to be positively correlated with physical exercise-induced improvements in PL (β = 0.51,
p
= 0.01).
Conclusions
The results from this study are very useful for further public health activities, which aim at helping physically inactive adults to adopt a physically active lifestyle as well as for the development of further PL intervention strategies. This pilot-study was a first attempt to measure PL in inactive adults. Yet, a validated measurement tool is still not available. Further research is necessary to determine the psychometric properties for this PL questionnaire.

Intergenerational transmission of the positive effects of physical exercise on brain and cognition
Physical exercise has positive effects on cognition, but very little is known about the inheritance of these effects to sedentary offspring and the mechanisms involved. Here, we use a patrilineal design in mice to test the transmission of effects from the same father (before or after training) and from different fathers to compare sedentary- and runner-father progenies. Behavioral, stereo-logical, and whole-genome sequence analyses reveal that paternal cognition improvement is inherited by the offspring, along with increased adult neurogenesis, greater mitochondrial citrate synthase activity, and modulation of the adult hippocampal gene expression profile. These results demonstrate the inheritance of exercise-induced cognition enhancement through the germline, pointing to paternal physical activity as a direct factor driving offspring’s brain physiology and cognitive behavior.

Environmental enrichment and exercise are better than social enrichment to reduce memory deficits in amyloid beta neurotoxicity
Recently, nongenetic animal models to study the onset and development of Alzheimer’s disease (AD) have appeared, such as the intrahippocampal infusion of peptides present in Alzheimer amyloid plaques [i.e., amyloid-β (Aβ)]. Nonpharmacological approaches to AD treatment also have been advanced recently, which involve combinations of behavioral interventions whose specific effects are often difficult to determine. Here we isolate the neuroprotective effects of three of these interventions—environmental enrichment (EE), anaerobic physical exercise (AnPE), and social enrichment (SE)—on Aβ-induced oxidative stress and on impairments in learning and memory induced by Aβ. Wistar rats were submitted to 8 wk of EE, AnPE, or SE, followed by Aβ infusion in the dorsal hippocampus. Short-term memory (STM) and long-term memory (LTM) of object recognition (OR) and social recognition (SR) were evaluated. Biochemical assays determined hippocampal oxidative status: reactive oxygen species, lipid peroxidation by thiobarbituric acid reactive substance (TBARS) test, and total antioxidant capacity by ferric reducing/antioxidant power (FRAP), as well as acetylcholinesterase activity. Aβ infusion resulted in memory deficits and hippocampal oxidative damage. EE and AnPE prevented all memory deficits (STM and LTM of OR and SR) and lipid peroxidation (i.e., TBARS). SE prevented only the SR memory deficits and the decrease of total antioxidant capacity decrease (i.e., FRAP). Traditionally, findings obtained with EE protocols do not allow discrimination of the roles of the three individual factors involved. Here we demonstrate that EE and physical exercise have better neuroprotective effects than SE in memory deficits related to Aβ neurotoxicity in the AD model tested.

Priority of nutrition and exercise in depression management: triangulating mini-review of past and recent evidence with clinical practice guidelines
Background
Chronic low-grade systemic inflammation (CLGSI) is implicated in depression and its amelioration. Pro-inflammatory nutrition and inactivity are associated with CLGSI. We triangulated the degree to which recent literature on anti-inflammatory nutrition and physical activity/physical exercise (PA/PE) corroborates the extant body of knowledge related to depression management and is reflected in the guidelines of leading mental health domains (national/international mental health associations/bodies).
Methods
We used mini-review methodology. The search was narrowed to recent state-of-the-art literature (2024) in PubMed, on diet and exercise specifications in depression management. Then, we compared recommendations of aforementioned domains regarding diet and PA/PE in depression management.
Results
Of 73 nutrition source studies, 50 (68%) focused on anti-inflammatory whole food, plant-based (WFPB) nutrition to manage depression; 4 (5%) on reducing consumption of animal-sourced foods; 16 (23%) focused on the effect of ultra-processed food (UPF) and its role in depression and its avoidance vis-à-vis its anti-depressant effects. Of the 55 PA/PE source studies, 49 (89%) focused on the effects of aerobic exercise; 14 (29%) described specific parameters to achieve an anti-depressant effect and 35 (71%) were non-specific. Twelve (22%) studies focused on resistance muscle training; 2 (17%) that reported specific training parameters and 10 (83%) that were non-specific. Nine domains were identified with established depression management guidelines: Australia/New Zealand; Canada; Europe (Belgium, Scotland, Spain); United Kingdom; United States; WFSBP and ASLM; and World Health Organization. Regarding nutrition, 5 (55%) domains recommended WFPB nutrition; 4 (44%) reduced animal-sourced foods; and 3 (33%), avoidance of UPF. With respect to sedentarism, 3 (33%) domains recommended reduced prolonged sitting. Eight domains (89%) mentioned aerobic exercise; 3 (33%) resistance training. Three domains mentioned aerobic exercise non-specifically; 5 (56%) made specific recommendations. Three domains mentioned resistance muscle training; 2 (22%) made non-specific recommendations and 1 (11%) made specific recommendations.
Conclusions
Disparities that exist in leading depression management guidelines vis-à-vis inclusion of evidence-informed nutrition and PA/PE recommendations, warrant reconciliation. Evidence supporting anti-depressant WFPB nutrition and limiting pro-inflammatory animal-sourced food and UPF and supporting anti-inflammatory aerobic exercise and resistance training warrants being translated into national/international depression management guidelines as consistently as recommendations for pharmacotherapy and psychotherapy.

Effect of physical activity promotion program on adherence to physical exercise among patients with type II diabetes in North Shoa Zone Amhara region: a quasi-experimental study
Background
Diabetes is a significant global public health issue that necessitates self-management. However, this is difficult to put into practice and requires a new approach. The purpose of this study was to assess the effects of a physical activity promotion program on adherence to recommended physical activity and lessons to improve self-management.
Methods
A quasi-experimental study was conducted from January 2020 to February 2021 at North Shoa Zone Public Hospital. The study enrolled 216 type II diabetic patients from four public hospitals. Data were entered into Epi Data V.3.1 and analyzed using SPSS version 22. Data were presented as means of standard deviations for continuous variables and percentages for categorical variables. Intervention and control groups were compared before and after intervention using independent t-tests. A p-value less than 0.05 was considered significant for all statistical tests.
Results
A total of 216 type II diabetics participated in this study. Physical activity promotion programs increased adherence to the recommended number of days and duration (spending time) of physical activity (p < 0.0001). Participants who engaged in the physical activity promotion program significantly increased the mean scores for exercising moderate-intensity activities and spending time (p < 0.05), walking for at least 10 min continuously and spending time (p < 0.05), exercising moderate-intensity recreational activities and spending time (p < 0.05).There was a significant reduction in mean fasting blood glucose after participating in a physical activity program (p < 0.05).
Conclusion
This study demonstrates that a physical activity promotion program makes a significant difference in patient compliance with recommended physical activity and effectively improves patient glycemic control. Health care providers should integrate physical activity programs into existing systems as a common therapeutic service. Primary care platforms such as health posts and health centers can play a key role in integrating health promotion programs to improve self-management behaviors.
