Effects of high-intensity training on physiological and hormonal adaptions in well-trained cyclists
2017
Purpose: This study aimed to compare the effects of three different high-intensity training (HIT) models, balanced for total load but differing in training plan progression, on endurance adaptations. Methods: Sixty-three cyclists (peak oxygen uptake (V˙ O2peak) 61.3 T 5.8 mLIkgj1 Iminj1 ) were randomized to three training groups and instructed to follow a 12-wk training program consisting of 24 interval sessions, a high volume of low-intensity training, and laboratory testing. The increasing HIT group (n = 23) performed interval training as 4 16 min in weeks 1–4, 4 8 min in weeks 5–8, and 4 4 min in weeks 9–12. The decreasing HIT group (n = 20) performed interval sessions in the opposite me…
African and European HIV-positive women: psychological and psychosocial differences.
2000
The objectives were to study and compare the psychosocial and psychopathological aspects of HIV infection in African and European HIV-positive women living in France. All women included were seen in a semi-structured interview to assess personal history, history of their HIV infection, social and family relationships, preoccupation with childbearing and concerns about HIV infection and its prognosis. The comparison of psychological and psychosocial factors between HIV-positive African and European women showed certain significant differences. The demographic characteristics did not differ, except for current professional activity, with more African women being unemployed. The medical aspect…
The Free Radical Theory of Aging Revisited: The Cell Signaling Disruption Theory of Aging
2013
AbstractSignificance: The free radical theory of aging has provided a theoretical framework for an enormous amount of work leading to significant advances in our understanding of aging. Up to the turn of the century, the theory received abundant support from observations coming from fields as far apart as comparative physiology or molecular biology. Recent Advances: Work from many laboratories supports the theory, for instance showing that overexpression of antioxidant enzymes results in increases in life-span. But other labs have shown that in some cases, there is an increased oxidative stress and increased longevity. The discovery that free radicals can not only cause molecular damage to …
The Transition from Hospital to Home: Older People's Experiences
2015
The amount of older patients who are discharged from hospitals while continuing to need care is increasing in Norway. The transition between different care services has the potential for high rates of medication errors, incomplete or inaccurate information transfer, and lack of appropriate follow-up care. Thus, insight into the transition process is vital to understanding the complexity and vulnerability the patients are exposed to in this process. The aim of this phenomenological hermeneutic study was to describe and illuminate the lived experiences of older home residents during the transitions from hospital to home. Data were collected through narrative interviews, and an interpretation …
Psychological resilience and active aging among older people with mobility limitations.
2020
Active aging refers to striving for well-being through preferred activity and may be restricted with declining mobility. We investigated whether psychological resilience, i.e., the ability to tolerate hardship, can aid older people in being active despite mobility limitations. Participants were 961 community-dwelling persons aged 75, 80, or 85 years living in Jyväskylä, Central Finland. Mobility limitations were indicated as self-reported difficulty in walking 2 km. Categories were no difficulty (reference), difficulty, and unable to walk. Resilience was assessed with the 10-item Connor–Davidson Resilience Scale and active aging with the University of Jyvaskyla Active Aging scale. Data were…
Assimilative and Accommodative Coping and Older People’s Leisure Activities
2019
Objectives: Assimilative and accommodative coping strategies have hardly been studied in relation to leisure activities in old age. We investigated whether tenacious goal pursuit (TGP) and flexible goal adjustment (FGA) influence the association between physical performance and participation in leisure activities. Methods: A cross-sectional analysis was conducted among 187 community-dwelling people aged 79 to 93 years. TGP, FGA, and leisure activity participation were asked with questionnaires. Physical performance was assessed with the Short Physical Performance Battery (SPPB). Results: TGP moderated the relationship between physical performance and leisure activity participation. Despite…
Living with Long Term Conditions from the Perspective of Family Caregivers. A Scoping Review and Narrative Synthesis
2021
(1) Background: When living with one or more long term conditions (LTCs), both the patient and the family experience the impact of the condition at different levels. The family’s needs and perceptions should be considered in the process of caring for people with LTCs. The aim of this review is to understand “the process of living with LTCs” from a family perspective. (2) Methods: A scoping review and narrative synthesis were conducted using a systematic methodology in MEDLINE, CINAHL, Web of Science and PsycINFO, in English and Spanish, including evidence from 2018. (3) Results: A total of 28 articles were included in the review. Acceptance, coping, self-management, integration, and adjustm…
How we compensate for memory loss in old age: adapting and validating the Memory Compensation Questionnaire (MCQ) for Spanish populations.
2012
Compensating entails using external strategies and mechanisms that help overcome or alleviate the decreasing memory function that comes with age. This study aims to adapt and validate the MCQ in the elderly Spanish population. A total of 403 elderly people aged between 65 and 92 in the city of Valencia (Spain) completed the questionnaire for the validation process. The factorial validity of the scale was tested using confirmatory factor analysis. The result showed a first order five-factor model with 23 items that met the criteria for model fit according to multiple fit indices. As a general conclusion, the adaptation into Spanish provided a reliable and valid measure of compensation in the…
Age identification in the framework of successful aging. A study of older Finnish people.
2003
A person-oriented approach was used in a study of age identification among community-dwelling older people. The study was based on 8-year follow-up data; 843 persons aged 65–84 were involved in the first phase of the study, and 426 persons aged 73–92, in the second phase. Loosely, on the basis of the distinction between successful, usual, and pathological aging (Rowe & Kahn, 1987, 1997), participants were grouped according to their self-ratings of cognitive and physical functioning as “Positive,” “Negative,” and “Others.” Participants possessing at least 4 out of the 5 criteria used as indicators of successful aging in the study (no illness or injury presenting problems in daily life, …
The lived experience of aging in community-dwelling elders in Valencia, Spain: a phenomenological study.
1995
The purpose of this qualitative research study was to explore the lived experience of aging in community-dwelling elders in Valencia, Spain. A bilingual, bicultural endeavor, this research was a collaborative project conducted by nurse educators in New York City and Valencia. Parse's theory of human becoming guided the research, and van Kaam's phenomenological method of analysis was used to identify common elements and major themes of experience. Findings revealed the meaning of aging to be confirming triumphs through the forceful enlivening of bridled potency. These findings were conceptually consistent with Parse's major themes of meaning, rhythmicity, and cotranscendence. Implications f…
