Body balance control represents a key factor preventing falls and subsequent injuries in seniors aged 65+. Intervention based on yoga exercises seem to be effective in improving balance.
The ...objective is to analyse and compare changes in static, dynamic, and total balance scores, changes in body composition and social indices as effects of yoga-based intervention.
A total of 500 participants (234 men aged 74.5 SD±7.74 and 266 women aged 76.9 SD±7.23) were assessed using the Tinetti Balance Assessment Tool, the InBody 230 bioimpedance body composition analyser, and the SF-36 Health Survey, applied to pre and post-testing. The experimental group (n=262; 122 males; 140 females) underwent a four-week yoga-based intervention, 30 minutes daily, while the control group (n=238; 112 males; 126 females) underwent its usual daily programme at senior homes or centres. The ANOVA model, consisting of the Group, Stage, Subject and Group × Stage interaction factors, was used for data evaluation.
Intervention led to improvements in the static, dynamic and total balance scores in the experimental group compared to the control group. The results of SF-36 showed positive changes in the psychosocial aspects of health, such as promoting of calmness and happiness in male seniors and reducing fatigue, nervousness and depression in female seniors. The post-intervention decrease in body fat percentage and increase in muscle mass in seniors is discussed.
The four-week yoga-based intervention had positive effects on the static, dynamic and total balance scores, body composition and social status.
A systematic review and meta-analysis of studies demonstrated a relationship between sex and balance determinants in seniors; however, no study has focused on sex-related differences in static and ...dynamic balance performance after a physical intervention as primary interest. The aim was to investigate sex differences in the static and dynamic balance performance after a 4-week physical intervention based on yoga in seniors 65+ years of age. Five-hundred participants (234 males, 266 females) were assessed with the Tinetti Balance Assessment Tool in pre-and post-testing. The experimental group (122 males, 140 females) underwent the intervention, while the control group (112 males, 126 females) ran their usual daily program. ANCOVA model was used for the statistical evaluation of the results. No sex differences were found in balance performance after a short-term physical intervention in seniors 65+ years of age. At the same time, a significant positive shift was demonstrated in performance in both static and dynamic balance.
Background: Body balance control represents a key function for the physical activities of elderly people aged sixty-five and over. Due to the biological and psychosocial changes in this age group, ...yoga-based intervention appears to be beneficial to maintaining their ability to balance along with related mental aspects of health. Objective: The aim of the presented study was to examine the effects of the 4-week yoga-based intervention on balance, body composition and the mental health aspects of elderly men. Methods: 67-80-year-old elderly men (N = 234, mean age 72.5 ± 7.7 years) were assessed with The Tinetti Balance Assessment Tool, bioimpedance body composition analyser InBody 230 and the Health Survey SF-36, applied for the pre- and post-testing. The experimental group (n = 122) underwent the 4-week intervention based on yoga exercises, while the control group (n = 112) had a usual daily program at their senior homes or centers. Results: The yoga intervention led to significant improvement of both the static balance and gait scores compared to the control group, with medium effect size, ηp2 = .070 and .080. The intervention also had an effect on the decrease of body fat percentage (by 1.7%) and an increase in muscle mass (by 1.3 kg), with a large effect size, ηp2 = .214 and .301. Results of the Health Survey showed that overall mental health did not change significantly although positive improvement in two items connected with emotional problems. Conclusions: A short-term yoga-based intervention may have a significant positive influence on physical abilities such as balance control and body composition rather than on mental health aspects in elderly men aged sixty-five and over.
The results of human biological and cultural evolution are currently at odds. A prosperous consumer lifestyle as a result of cultural evolution does not provide enough of the adaptive stimuli that ...man claims as a result of natural biological evolution. The aim of this article is to define civilization dilemmas in relation to the quality of life of modern man. The chosen methods were the methods of analysis, synthesis, induction and deduction applied to the method of anchored theory in the sense of studying the concept as the main category, as well as causal and operational thinking. A synthesis of evidence and a critical and reproducible summary of the results of available publications on the subject were performed as well. The results of the study provide knowledge that quality longevity (delaying senescence) requires a certain degree of hormetic stress, especially in the area of caloric restriction, physical and mental exertion and hardening (salutogenetic quadrivium). The first dilemma analyzed is the autodeterministic discomfort self-limitation of the ascetic type. Within the framework of cognitive dissonance and causal attribution, it leads to the question of whether the advanced discomfort will be balanced by a subsequent comfortable life. The second dilemma analyzed is the use of technological possibilities of biotracking (BZV, biomonitoring), which will be increasingly, in accordance with the progress of knowledge, offered in deciding on the nature of necessary human activities, which can be interpreted as a restriction on freedom of decision. Conclusions: The analyzed dilemmas will increasingly affect a person's quality of life in their self-limiting form.

• The diversity of cytokinin (CK) metabolites suggests their interconversions are the predominant regulatory mechanism of CK action. Nevertheless, little is known about their directionality and ...kinetics in planta.
• CK metabolite levels were measured in 2-wk-old Arabidopsis thaliana plants at several time points up to 100 min following exogenous application of selected CKs. The data were then evaluated qualitatively and by mathematical modeling.
• Apart from elevated levels of trans-zeatin (tZ) metabolites upon application of N⁶-(Δ²-isopentenyl)adenine (iP), we observed no conversions between the individual CK-types – iP, tZ, dihydrozeatin (DHZ) and cis-zeatin (cZ). In particular, there was no sign of isomerization between tZ and cZ families. Also, no increase of DHZ-type CKs was observed after application of tZ, suggesting low baseline activity of zeatin reductase. Among N-glucosides, those of iP were not converted back to iP while tZ N-glucosides were cleaved to tZ bases, thus affecting the whole metabolic spectrum.
• We present the first large-scale study of short-term CK metabolism kinetics and show that tZ N7- and N9-glucosides are metabolized in vivo. We thus refute the generally accepted hypothesis that N-glucosylation irreversibly inactivates CKs. The subsequently constructed mathematical model provides estimates of the metabolic conversion rates.
