Effect of the subjective intensity of fatigue and interoception on perceptual regulation and performance during sustained physical activity

Background The subjective experience of fatigue impairs an individual’s ability to sustain physical endurance performance. However, precise understanding of the specific role perceived fatigue plays in the central regulation of performance remains unclear. Here, we examined whether the subjective intensity of a perceived state of fatigue, pre-induced through prior upper body activity, differentially impacted performance and altered perceived effort and affect experienced during a sustained, isometric contraction in lower body. We also explored whether (cardiac) interoception predicted the intensity of experienced perceptual and affective responses and moderated the relationships between constructs during physical activity. Methods Using a repeated-measures study design, thirty male participants completed three experimental conditions, with the intensity of a pre-induced state of fatigue manipulated to evoke moderate (MOD), severe (SEV) and minimal (control; CON) intensity of perceptions prior to performance of the sustained contraction. Results Performance of the sustained contraction was significantly impaired under a perceived state of fatigue, with reductions of 10% and 14% observed in the MOD and SEV conditions, respectively. Performance impairment was accompanied by greater perceived effort and more negative affective valence reported during the contraction. However, effects were limited to comparisons to CON, with no difference evident between the two experimental trials (i.e. MOD vs. SEV). Individuals’ awareness of their accuracy in judging resting heartbeats was shown to predict the subjective intensity of fatigue experienced during the endurance task. However, interoception did not moderate the relationships evident between fatigue and both perceived effort and affective valence. Conclusions A perceived state of fatigue limits endurance performance, influencing both how effortful activity is perceived to be and the affective experience of activity. Though awareness of interoceptive representations of bodily states may be important to the subjective experience of fatigue, interoception does not modulate the relationships between perceived fatigue and other perceptual (i.e. effort) and affective constructs.

The Effects of Six-Month Subalpine Training on the Physical Functions and Athletic Performance of Elite Chinese Cross-Country Skiers

Purpose: This study investigated the changes in the blood indices, specific athletic abilities, and physical fitness of outstanding cross-country skiers, trained in the subalpine; Methods: Twenty-eight athletes (twenty males and eight females) from the National Cross-country Ski Training Team completed sub-alpine training during the 2020–2021 snow season. The athletes′ physical functions were evaluated by collecting blood from elbow veins and measuring blood biochemical indexes. To compare the treadmill roller-skiing athletic ability and physical fitness of athletes before and after subalpine; Results: Male and female athletes showed different trends in red blood cells (RBC), hemoglobin (Hb), cortisol (C), Creatine Kinase (CK) and blood urea (BU) (p < 0.05 or p < 0.01). Overall, the female athletes’ mean values of RBC, Hb, CK, and BU were lower than that of male athletes, while C was just the opposite. Comparing the athletic performance of athletes before and after the subalpine, it was found that blood lactate concentrations were significantly lower in both male and female athletes at the same load intensity (p < 0.05 or p < 0.01), whereas 10 km endurance running and 1 RM deep squat were significantly higher in both male and female athletes (p < 0.05 or p < 0.01). Conclusions: After 6 months of subalpine training, cross-country skiers improved their oxygen-carrying capacity and anabolism, and showed significant improvements in specific athletic ability, physical endurance, acid tolerance and 1 RM absolute strength for both male and female athletes.

Analysis of Resilience of Family of Recipients of the Gemilang NTB Social Safety Net Program (JPS) During the Covid-19 Pandemic

The goal of this study is to figure out how resilient families who get the Gemilang Social Safety Net (JPS) are in terms of physical resilience, economic resilience, social psychological and sociocultural resilience, and family resilience based on each type of work. Another part of this study will look at how income, the number of people living with you, and how many times you’ve been given JPS Gemilang affect your physical resilience. This is a quantitative study. The people who took part in this study were people who had JPS Gemilang stage III in the province of West Nusa Tenggara (NTB). Samples were chosen by a method called stratified random sampling. This study used the Treebox Method and multiple regression analysis to figure out how total income, number of dependents, and number of times receiving JPS Gemilang affected physical endurance, economic resilience, socio-psychological, and socio-cultural resilience, as well as how many times they were given the JPS Gemilang drug. According to a study done by looking at 100 samples, each person who gets JPS Gemilang has a high level of family resilience. This is true for the physical, economic, socio-psychological, and socio-cultural aspects that make up a person’s family. All of JPS Gemilang are in the top group. It doesn’t matter what job you do; your family is going to be able to handle it. People who work as professional staff, such as honorary teachers, honorary staff members, and teachers, do a lot of work that helps families be more resilient in general, but when they look at each of these things individually, they’re in the middle. Physical resilience, economic resilience, socio-psychological and socio-cultural resilience don’t seem to be affected by income, number of dependents, or number of times JPS Gemilang has been given to people. This is based on statistics.

Effects of ashwagandha root extract on physical performance – a clinical review

Sport is an important aspect of human life, affecting mental and physical health. Physical activity is one of the most effective ways of preventing the diseases of civilisation, such as coronary heart disease, hypertension, obesity and diabetes. There are many substances and methods that are used by athletes to improve physical performance, increase muscle mass and strength, increase concentration or suppress excessive emotions or reduce body weight to improve sports results. However, there is a need for research to find natural substances of plant origin, the use of which will lead to an increase in physical performance and will be fully legal and without side effects. Some scientists are conducting research into the use of ashwagandha root extract to improve physical performance. The aim of this study was to assess the efficacy and safety of ashwagandha root extract in the treatment of insomnia, anxiety and in reducing stress. Our study material consisted of publications, which were found in PubMed, ResearchGate and Google Scholar databases. In order to find the proper publications, the search has been conducted with the use of a combination of key words like: ''ashawagandha'', ''physical performance'', ''physical endurance'', ''muscle strength". The first step was to find proper publications from the last 15 years. The second step was to carry out an overview of the found publications.

Learning to Work With Chronic Health Conditions: How Time Since Diagnosis Affects Older Workers' Vitality and Worries

Background. Chronic health conditions (CHCs) pose stark detrimental effects on the health and abilities of older workers. The extent of these effects depend on the CHC, the time since its diagnosis and the type of health measure: a rarely explored combination of heterogeneities. Objective. This study examined how four existing and newly diagnosed CHCs influences older workers’ vitality and worries about enduring physically and mentally until retirement age. Method: Data from two waves of the NIDI Pension Panel survey conducted in the Netherlands in 2015 and 2018 were used. We analyzed a sample of 1,894 older workers between the ages of 60-62 years at wave 1 using conditional change ordinal least square regression models. Results: Having a CHC at wave 1 was associated with lower levels of vitality and higher levels of worries at wave 2. These effects of CHCs on vitality and worries were much larger for older workers who were newly diagnosed with CHCs compared to those who experienced CHCs for longer. Intriguingly, the new diagnosis of physically disabling conditions increased worries about physical endurance at wave 2, while the new diagnosis of mentally disabling conditions increased worries about mental endurance at wave 2. Conclusion: By distinguishing the effects of four existing and newly diagnosed CHCs on vitality and worries, this study allows the identification of vulnerable groups of older workers. The findings may inform work accommodations and interventions which could improve both the quality and sustainability of work lives, while promoting healthy ageing of older workers.

A Study to Evaluate the Quality of Life of Patients with Diabetes Mellitus

Aim: The aim of the study was to evaluate the QOL of patients with Diabetes Mellitus. Study Design: This was a prospective, observational study. Duration of Study: The study was conducted from August 2019 to January 2021 in Yashoda Hospital, Hyderabad. Methodology: Patients of either sex with ≥1year history of diabetes willing to give the consent were included in the study. Patients of either sex with <1year history of DM, Pregnant/lactating women and patients not willing to give the consent were excluded from the study. Data on Blood glucose levels (FBS, PPBS) and HbA1C was also obtained and assessed. QOLID questionnaire was administered to the patients and assessed which consisted of a set of 34 items representing 8 domains such as Role limitation due to the physical health, Physical endurance, General health, Treatment satisfaction, Symptom botherness, Financial worries, Mental health, and Diet satisfaction). Results: A total of 200 patients were analysed in the study,108(54%) were males and 92(46%) were females. The average age of the patients was 58.5 years with majority being 51-70years (73.5%) of age. Patients with higher age and females had poor QOL compared to others. The correlation between various categorical variables with that of scores of QOL in various domains was assessed, Age of the patients influenced QOL score in various domains like RLPH (p value-0.038), PE (p value-0.0183), and SB (p value-0.0002), Gender has influenced QOL score in domains like RLPH (p value-0.0008), PE (p value-0.0106), TS (p value-0.0005) and Educational Qualification has influenced QOL score in RLPH (p value-0.0008), GH (p value-<0.0001), TS (p value-<0.0001), E/MH (p value-<0.0001). Conclusion: The results concluded that overall QOL was noticeably low in Diabetic patients especially in Women and elderly thus indicating that Diabetes management is not restricted to treatment but also requires attention on QOL of patients.

General endurance of first-year university students in the context of Covid-19 pandemics
