Neurodegenerative Erkrankungen
Neurodegenerative Erkrankungen wie Alzheimer, Parkinson, ALS, CJK oder Demenz haben oft Gemeinsamkeiten und können sich gegenseitig begünstigen.
"Gibt es einen gemeinsamen Mechanismus bei der Entstehung neurodegenerativer Erkrankungen? Offenbar schon.
Bei den meisten dieser Krankheiten finden sich fehlgefaltete Proteine, die im Gehirn verklumpen, wobei diese Aggregate zunächst in einer begrenzten Hirnregion auftreten, von der aus sie sich sukzessive auf das restliche Gehirn ausbreiten......." (Thomas Müller / aerztezeitung.de)

Training und Gymnastik bei Rheuma und Bechterew
Körperliche Bewegung hält Patienten mit
rheumatischen Erkrankungen fit. Das gilt auch für Morbus Bechterew, rheumatoide Arthritis und für Arthrose.
"Patienten mit Morbus Bechterew wird von den meisten Rheumatologen heute eine gewisse sportliche Betätigung empfohlen. Es gibt sogar Sportgruppen speziell für diese Patienten, nicht selten Volleyballgruppen. "

Fasziales Gewebe
.......Das Besondere an diesem Bindegewebe ist dessen enorme Anpassungsfähigkeit an die geforderte Belastung. Es reagiert auf regelmäßig wiederkehrende Belastungen oder dauerhafte Anforderungen.
Bei einem regelmäßigen Trainingsreiz brauchen die Faszien ca. 6-24 Monate um außerordentlich fest, stark, belastbar und gleichzeitig extrem elastisch zu werden und sich außerdem im ganzen Körper zu verbreiten.
Die faszialen Gewebe bei jungen Menschen haben eine ausgeprägte Wellenstruktur, die an elastisch-schwingende Federn erinnern. Somit wird die Jugend mit elastischer Dynamik verbunden, denn je älter der Mensch wird, desto stärker geht diese wellenartige Struktur und somit die Elastizität verloren.
Es spricht allerdings nichts gegen ein „spätes“ Einsteigen in diese Trainingsform, denn gehört man einmal zum bewegungsarmen Schreibtischtäter oder wird durch altersbedingte Schonhaltung verhindert, entwickeln sich zunehmend die so genannten „Cross-Links“, die die ungeordnete und planlose Querverbindung der Faszienstruktur darstellen. Dies führt zum Elastizitätsverlust, zum erschwerten Gleiten und zu Verklebungen. ......

Development of a Common Outcome Data Set for Fall Injury Prevention Trials
The Prevention of Falls Network Europe Consensus
Keywords:
- accidental falls;
- aged;
- fractures;
- consensus development;
- outcome measures
The
prevention of injury associated with falls in older people is a public
health target in many countries around the world. Although there is good
evidence that interventions such as multifactorial fall prevention and
individually prescribed exercise are effective in reducing falls, the
effect on serious injury rates is unclear.1,2
Historically, trials have not been adequately powered to detect injury
endpoints, and variations in case definition across trials have hindered
meta-analysis.1
It is possible that fall-prevention strategies have limited effect on falls that result in injuries or are ineffective in populations who are at a higher risk of injury.
Further research is required to determine whether fall-prevention interventions can reduce serious injuries.

Prevention
of Falls Network Europe (ProFaNE) is a collaborative project to reduce
the burden of fall injury in older people through excellence in research
and promotion of best practice (http://www.profane.eu.org).
The European Commission funds the network, which links clinicians,
members of the public, and researchers worldwide.
The aims are to identify major gaps in knowledge in fall injury prevention and to facilitate the collaboration necessary for large-scale clinical research activity, including clinical trials, comparative research, and prospective meta-analysis.
Work is being undertaken in a 4-year program. As a first step, the development of a common set of outcome definitions and measures for future trials or meta-analysis was considered.

Exercise Training and Nutritional Supplementation for Physical Frailty in Very Elderly People
Exercise Training and Nutritional Supplementation for Physical Frailty in Very Elderly People
The decline in muscle strength and mass during aging1,2 has been linked to physical frailty, falls, functional decline, and impaired mobility in very elderly people3-5.
Although many factors, including chronic illness, a sedentary lifestyle, nutritional deficiencies, and aging itself, may contribute to muscle weakness and loss of skeletal-muscle mass in people of advanced age,6-10 currently only skeletal-muscle disuse11,12 and undernutrition13-15 are potentially preventable or reversible with targeted interventions.
Muscle dysfunction associated with malnutrition may improve with nutritional supplementation in younger patients16,17. Even in healthy elderly men, a multinutrient supplement augmented muscle hypertrophy, although not muscle strength, during a resistance training regimen similar to the one described here18.
We hypothesized that physical frailty is partially mediated by skeletal-muscle disuse and marginal nutritional intake, and should therefore be reduced by interventions designed to reverse these deficits.

We hypothesized that physical frailty is partially mediated by skeletal-muscle disuse and marginal nutritional intake, and should therefore be reduced by interventions designed to reverse these deficits.
Methods
Study Design
Detailed descriptions of the rationale and design of the Boston FICSIT (Frailty and Injuries: Cooperative Studies of Intervention Techniques) study19 and the entire FICSIT trial20 have been published elsewhere. Briefly, the Boston FICSIT study was a randomized, placebo-controlled, 10-week clinical trial in which the subjects were assigned to receive lower-extremity resistance training, a multinutrient supplement, both treatments, or a placebo activity and supplement. The study was approved by the human investigations review committees at New England Medical Center and the Hebrew Rehabilitation Center for Aged, and written informed consent was obtained from each subject.Study Population
Volunteers were recruited from the residents of a 725-bed facility providing long-term care of the elderly. The criteria for inclusion were residential status, an age over 70 years, and the ability to walk 6 m. Subjects were excluded if they had severe cognitive impairment, rapidly progressive or terminal illness, acute illness or unstable chronic illness, myocardial infarction, fracture of a lower extremity within the six months before the study, or insulin-dependent diabetes mellitus; if they were on a weight-loss diet or undergoing resistance training at the time of enrollment; or if tests of muscle strength revealed a musculoskeletal or cardiovascular abnormality.Interventions
Resistance Training
Subjects assigned to exercise training underwent a regimen of high-intensity progressive resistance training21 of the hip and knee extensors 3 days per week for 10 weeks. These muscle groups were chosen because of their importance in functional activities22. For each muscle group, the resistance was set at 80 percent of the one-repetition maximum (the maximal load that could be lifted fully one time only)23. To maintain the intensity of the stimulus, the load was increased at each training session, as tolerated by the subject. Strength testing was repeated every two weeks to establish a new base-line value.Training sessions lasted 45 minutes and were separated by one day of rest. Each repetition lasted six to nine seconds, with a one- to two-second rest between repetitions and a two-minute rest between the three sets of eight lifts. All exercise sessions were supervised individually by a single exercise trainer, who was a certified therapeutic recreation specialist.
The knee extensors were trained with the use of the UNEX II chair (J.A. Preston, Clifton, N.J.). The hip extensors were trained in the first 53 subjects with the use of a wall-mounted cable-pulley system (G.E. Miller, New York). In the other 47 subjects, a double leg press (Keiser Sports Health Equipment, Fresno, Calif.) was used in place of the cable-pulley system, since it allowed for better positioning of the subject. There were no differences at base line or in treatment outcomes between subjects trained on these two machines............

Implementation of multifactorial interventions for fall and fracture prevention
Abstract
Over 60% of falls experienced by older
people result from multiple aetiological factors. Preventing falls in
individual patients
requires the identification and treatment of these
interacting factors. Multifactorial interventions have been successful
in some, but not all, fall prevention trials.
Preventing falls in populations requires selection of the population
most likely
to benefit, and selection of the particular
interventions shown to have been effective in this group. The
implementation of
preventive measures has been low despite strong
evidence that fall and fractures can be reduced. Misconceptions about
the
potential for prevention in old age, the time to
effect improvement, resource issues and the nature of the interventions
contribute
to the low uptake. An improved system of delivery
of proven preventive measures is needed.

Abstract
Objectives. This randomized controlled trial studied the effects of a low- to moderate-intensity group exercise program on strength,
endurance, mobility, and fall rates in fall-prone elderly men with chronic impairments.
Methods. Fifty-nine community-living men 
with specific fall risk factors (i.e., leg weakness, impaired gait or balance, previous falls) were randomly assigned to
a control group 
or to a 12-week group exercise program 
.
Exercise sessions (90 minutes, three times per week) focused on
increasing strength and endurance and improving mobility
and balance. Outcome measures included isokinetic
strength and endurance, five physical performance measures, and
self-reported
physical functioning, health perception, activity
level, and falls.

Results. Exercisers showed significant improvement in measures of endurance and gait. Isokinetic endurance increased 21% for right
knee flexion and 26% for extension. Exercisers had a 10% increase ( p < .05) in distance walked in six minutes, and improved ( p
< .05) scores on an observational gait scale. Isokinetic strength
improved only for right knee flexion. Exercise achieved
no significant effect on hip or ankle strength,
balance, self-reported physical functioning, or number of falls.
Activity
level increased within the exercise group. When
fall rates were adjusted for activity level, the exercisers had a lower
3-month
fall rate than controls (6 falls/1000 hours of
activity vs 16.2 falls/1000 hours, p < .05).
Discussion.
These findings suggest that exercise can improve endurance, strength,
gait, and function in chronically impaired, fall-prone
elderly persons. In addition, increased physical
activity was associated with reduced fall rates when adjusted for level
of
activity.

Strength training in the elderly
Effects on risk factors for age-related diseases / by: Hurley BF, Roth SM.
Source: Department of Kinesiology, College of Health & Human Performance, University of Maryland, College Park 20742, USA. bh24@umail.umd.edu
Abstract
Strength training (ST) is considered a promising intervention for reversing the loss of muscle function and the deterioration of muscle structure that is associated with advanced age.This reversal is thought to result in improvements in functional abilities and health status in the elderly by increasing muscle mass, strength and power and by increasing bone mineral density (BMD).
In the past couple of decades, many studies have examined the effects of ST on risk factors for age-related diseases or disabilities.
Collectively, these studies indicate that ST in the elderly: (i) is an effective intervention against sarcopenia because it produces substantial increases in the strength, mass, power and quality of skeletal muscle; (ii) can increase endurance performance; (iii) normalises blood pressure in those with high normal values; (iv) reduces insulin resistance; (v) decreases both total and intra-abdominal fat; (vi) increases resting metabolic rate in older men; (vii) prevents the loss of BMD with age; (viii) reduces risk factors for falls; and (ix) may reduce pain and improve function in those with osteoarthritis in the knee region.
However, contrary to popular belief, ST does not increase maximal oxygen uptake beyond normal variations, improve lipoprotein or lipid profiles, or improve flexibility in the elderly.

Systematic Review of Progressive Resistance Strength Training in Older Adults
systematic review von:
Abstract
Background. The aim of this systematic review was to quantify the effectiveness of progressive resistance strength training (PRT) to
reduce physical disability in older people.
Methods.
Randomized controlled trials were identified from searches of relevant
databases and study reference lists and contacts with
researchers. Two reviewers independently screened
the trials for eligibility, rated their quality, and extracted data.
Only
randomized controlled trials utilizing PRT as the
primary intervention in participants, whose group mean age was 60 years
or older, were included. Data were pooled using
fixed or random effect models to produce weighted mean differences (WMD) and 95% confidence intervals (CI). Standardized mean differences (SMD) were calculated when different units of measurement were used for the outcome of interest.
Results. 62 trials (n
= 3674) compared PRT with a control group. 14 trials had data available
to allow pooling of disability outcomes. Most trials
were of poor quality. PRT showed a strong positive
effect on strength, although there was significant heterogeneity (41
trials
[n = 1955], SMD 0.68; 95% confidence interval [CI] 0.52, 0.84). A modest effect was found on some measures of functional limitations such
as gait speed (14 trials [n = 798], WMD 0.07 meters per second; 95% CI 0.04, 0.09). No evidence of an effect was found for physical disability (10 trials [n = 722], SMD 0.01; 95% CI −0.14, 0.16). Adverse events were poorly investigated, but occurred in most studies where they were defined
and prospectively monitored.
Conclusions. PRT
results in improvements to muscle strength and some aspects of
functional limitation, such as gait speed, in older adults.
However, based on current data, the effect of PRT
on physical disability remains unclear. Further, due to the poor
reporting
of adverse events in trials, it is difficult to
evaluate the risks associated with PRT.

Abstract / Summary
Injuries resulting from falls in elderly people are a major public-health concern, representing one of the main causes of longstanding pain, functional impairment, disability, and death in this population.
The problem is going to worsen, since the rates of such injuries seem to be rising in many areas, as is the number of elderly people in both the developed and developing world.
Many methods and programmes to prevent such injuries already exist, including regular exercise, vitamin D and calcium supplementation, withdrawal of psychotropic medication, cataract surgery, professional environment hazard assessment and modification, hip protectors, and multifactorial preventive programmes for simultaneous assessment and reduction of many of the predisposing and situational risk factors.
To receive broader-scale effectiveness, these programmes will need systematic implementation. Care must be taken, however, to rigorously select the right actions for those people most likely to benefit, such as vitamin D and calcium supplementation and hip protectors for elderly people living in institutions.

Regular Heel-raise Training Focused on the Soleus for the Elderly
Evaluation of Muscle Thickness by Ultrasound
ABSTRACT
The soleus, one of the triceps surae muscles, greatly contributes to standing and walking. Strength training focused on the soleus could be important to prevent age-related deterioration in these functions.
We therefore investigated the effects of regular heel-raise training focused on the soleus for the elderly. Forty-nine healthy women aged 60 to 79 years trained for at least 40 days in a period of two months. Training consisted of a set of 100 repetitions per day of heel-raise with both legs in a standing position.
The training effect was evaluated by changes in each muscle thickness of the soleus and gastrocnemius medialis, which was measured using an ultrasound scanner, as well as plantar flexor strength.
The subjects' ability to perform the training and their subjective opinions of its effects were assessed by a questionnaire survey. Plantar flexor strength and thicknesses of the soleus and gastrocnemius medialis were increased significantly by the training.
The percentage increase in thickness was significantly greater for the soleus than for the gastrocnemius medialis (12.7% vs. 6.6%). These improvements did not significantly correlate with age.
The questionnaire results suggested that the elderly were able to safely and easily perform the heel-raise training at home. This study demonstrated that regular heel-raise training is an effective muscle training method for the elderly, focused on the soleus.

Fall risk assessment and ......
.........knee extensor muscle activity in elderly people
ABSTRACT
Purpose: The purpose of this study was to analyze relationships between the history of falls, tripping, sway, and knee extensor muscle strengths as a tool for fall risk assessment in elderly people. We examined effective fall prevention measures.
Methods: We investigated 102 elderly volunteers in the community. The subjects were classified according to history of falls, tripping, sway and 5 performance tests conducted to assess fall risk including Timed up-and-go test (TUG), Functional Reach test (FR), Hand grip and Reaction time (RT). In addition, the time serial data of the knee extensor muscle strength were acquired using a hand-held dynamometer.
Results: In comparison to the non-faller group, the faller group showed a significantly higher incident rate of tripping and sway. A frequency analysis using the Maximum Entropy Method revealed that the fallers group showed lower peak frequency (p=0.025). Also, the slope of the logarithmical spectrum was less steep in the fallers group (p=0.035). Also results from analysis of the peak force latency from the beginning of measurement to 50%, 80%, and 100% muscle strength, also showed that the faller group took more time for maximal voluntary contraction.
Conclusions: The frequency analysis of the time series date of peak force latency of knee extensor muscle strength revealed that the muscle activity differs in faller compared to non-fallers. This study suggested that knee extensor muscle isometric performance could possibly be used as a new tool for fall risk assessment. We concluded that exercises to raise maximal muscle strength and muscle response speed are useful for the prevention of falls.

ABSTRACT
Purpose: The purpose of this study was to analyze relationships between the history of falls, tripping, sway, and knee extensor muscle strengths as a tool for fall risk assessment in elderly people. We examined effective fall prevention measures.
Methods: We investigated 102 elderly volunteers in the community. The subjects were classified according to history of falls, tripping, sway and 5 performance tests conducted to assess fall risk including Timed up-and-go test (TUG), Functional Reach test (FR), Hand grip and Reaction time (RT). In addition, the time serial data of the knee extensor muscle strength were acquired using a hand-held dynamometer.
Results: In comparison to the non-faller group, the faller group showed a significantly higher incident rate of tripping and sway. A frequency analysis using the Maximum Entropy Method revealed that the fallers group showed lower peak frequency (p=0.025). Also, the slope of the logarithmical spectrum was less steep in the fallers group (p=0.035). Also results from analysis of the peak force latency from the beginning of measurement to 50%, 80%, and 100% muscle strength, also showed that the faller group took more time for maximal voluntary contraction.
Conclusions: The frequency analysis of the time series date of peak force latency of knee extensor muscle strength revealed that the muscle activity differs in faller compared to non-fallers. This study suggested that knee extensor muscle isometric performance could possibly be used as a new tool for fall risk assessment. We concluded that exercises to raise maximal muscle strength and muscle response speed are useful for the prevention of falls.

Falls in older people: epidemiology, risk factors and strategies for prevention
Falls in older people: epidemiology, risk factors and strategies for prevention
Abstract
Falls are a common and often devastating
problem among older people, causing a tremendous amount of morbidity,
mortality and
use of health care services including premature
nursing home admissions.
Most of these falls are associated with one or
more
identifiable risk factors (e.g. weakness, unsteady
gait, confusion and certain medications), and research has shown that
attention
to these risk factors can significantly reduce
rates of falling.
Considerable evidence now documents that the most
effective
(and cost-effective) fall reduction programmes have
involved systematic fall risk assessment and targeted interventions,
exercise
programmes and environmental-inspection and
hazard-reduction programmes.
These findings have been substantiated by
careful
meta-analysis of large numbers of controlled
clinical trials and by consensus panels of experts who have developed
evidence-based
practice guidelines for fall prevention and
management.
Medical assessment of fall risks and provision of
appropriate interventions
are challenging because of the complex nature of
falls.
Optimal approaches involve interdisciplinary collaboration in
assessment
and interventions, particularly exercise, attention
to co-existing medical conditions and environmental inspection and
hazard
abatement.
