Age-related decline of fine motor control commences even in middle adulthood. Less is known, however, whether age-related changes can be postponed through continuous practice. In this study we tested how age and professional expertise influence fine motor control in middle-aged adults. Forty-eight right-handed novices and experts (35 to 65 years) performed submaximal precision grip force modulation tasks with index or middle finger opposing the thumb, either with the right hand or the left hand. Novices revealed expected age-related differences in all performance measures (force initialization, mean applied force, variability), whereas experts outperformed novices in all outcome measures. Expertise seems to contribute to maintaining manual skills into older age, as indicated by the age and expertise interaction for the force initialization.

The global population of older people is steadily growing and challenging researchers in the human computer interaction community to design technologies to help them remain independent and preserve their quality of life. Researchers are addressing this challenge by creating assistive technology solutions using information appliances, such as personal digital assistants and mobile phones. Some have questioned whether older people can use information appliances because of age related problems. This chapter discusses work related to designing, implementing, and evaluating mobile applications for the aging. A discussion about what researchers should consider during the design process for information appliances shows the unique challenges posed by this population.

Assistance Systems

Due to the demographic change, hybrid work systems increasingly gain importance. Especially, robot based assistance systems show potential to respond individually to employee’s performance parameters. Existing technologies offer possibilities to capture individual performance parameters which can be transferred into a digital environment. Identified impairments, e.g. of the musculoskeletal system, can be used to design an individual work environment with human-robot collaboration that fits the employee’s needs to guarantee a low risk of physical harm due to work related strain. Following the employee’s capabilities, the simulation reveals stressful activities that can be transferred to the robot. Thus, the work system offers the opportunity to individually respond to the employee and the given tasks by creating a work situation that suits the employee’s preconditions. This paper presents an approach for capturing individual physical performance parameters in form of movement restrictions by a motion capturing system without markers and the transmission of the motion data into a digital human model. It will be shown how the simulation can be used to design a needs-based work place by integration of a robot based assistance system.

Aging is associated with a tissue degeneration phenotype marked by a loss of tissue regenerative capacity. Regenerative capacity is dictated by environmental and genetic factors that govern the balance between damage and repair. The age-associated changes in the ability of tissues to replace lost or damaged cells is partly the cause of many age-related diseases such as Alzheimer's disease, cardiovascular disease, type II diabetes, and sarcopenia. A well-established marker of the aging process is the length of the protective cap at the ends of chromosomes, called telomeres. Telomeres shorten with each cell division and with increasing chronological age and short telomeres have been associated with a range of age-related diseases. Several studies have shown that chronic exposure to exercise (i.e., exercise training) is associated with telomere length maintenance; however, recent evidence points out several controversial issues concerning tissue-specific telomere length responses. The goals of the review are to familiarize the reader with the current telomere dogma, review the literature exploring the interactions of exercise with telomere phenotypes, discuss the mechanistic research relating telomere dynamics to exercise stimuli, and finally propose future directions for work related to telomeres and physiological stress.

The western lifestyle, characterized by convenience food, television and PC’s taking its all on children as well as adults and is producing increased number of overweight, passive youngsters with lifestyle diseases. Spondylosis is degenerative inter vertebral disc with secondary proliferative osteoarthritis. Disc spaces collapse and associated ligament thickening and bony proliferation result in nerve root compression and narrowing of spinal canal. Cervical spondylosis which is a degenerative disorder in which structural and also functional derangements take place. It is an age related and also work-related disability usually found in the 30-60 years of age group. According to Ayurveda it is one among the Vataja Nanatmaja Vikara. There is no exact clinical entity mentioned in classics like cervical spondylosis, but it can be compared to Greevastambha, Apabahuka, Vishwachi Manyastamba, Manyagraha, Shirograham, Greevahundanam, Greevasandhigatavata. Cervical Spondylosis also known as cervical osteoarthritis or neck arthritis, is a common age-related condition that affects the joints and discs in our neck.

ObjectiveWith population ageing, the number of older workers is increasing and the number of work-related injuries in older people is also increasing. Occupational patterns and work-related injury patterns vary with age. This study aimed to compare the incidence and characteristics of work-related injuries in older and younger workers in Korea.MethodsWe conducted a retrospective review of the characteristics of workers hospitalised with work-related injuries from January 2010 to December 2014, using data from the National Hospital Discharge In-Depth Injury Survey in South Korea. The analysis was stratified by age into older (aged ≥65 years) and younger (aged 20–64 years) workers.ResultsThe hospitalisation rate in older workers was double that of younger workers (2014 IRR: 2.06, 95% CI 1.53 to 2.76). Compared with workers of conventional working-age, a higher proportion of injured older workers were female (33.1% vs 13.6%, p<0.001), injured due to falls (40.8% vs 28.5%) and injured while working on a farm (46.5% vs 6.3%, p<0.001). In older workers, work-related injuries were seasonal and peaked during summer, but there was little seasonality in injuries among younger workers.ConclusionOlder workers are more vulnerable to work-related injuries and have a different profile of work-related injuries from younger workers. Age-related differences in the injury profile need to be considered when developing workplace injury prevention policies and programmes, and the specific vulnerabilities of older workers need to be addressed.

Disruption of age-related processes seems to play a relevant role in health effects related to night shift (NS) work. We aim to verify whether NS work can influence biological age (BA), estimated through Zbieć-Piekarska’s epigenetic signature, based on methylation of five CpG sites in ELOVL2, C1orf132/MIR29B2C, TRIM59, KLF14, and FHL2. Forty-six female nurses working in NS were matched by age and length of employment with 51 female colleagues not working in NS. Each subject filled in a questionnaire (including the Effort Reward Imbalance (ERI) index to assess job stress) and gave a blood sample. Age acceleration (AA) was estimated by regressing BA on chronological age and taking the residuals. Multivariate linear regression models were applied. BA was not associated with NS. However, we did observe an increase in AA per each year in NS in subjects with overweight/obesity (β = 0.46, 95%CI: 0.05; 0.87, p = 0.03), experiencing work-related stress (β = 0.58, 95% CI: 0.10; 1.06, p = 0.018), or both (β = 0.66, 95% CI: 0.03; 1.29, p = 0.041). Although based on a small sample size, our findings suggest an increased BA only among hypersusceptible subjects and is worth further investigation, also in light of recent results suggesting a higher breast cancer risk in women with increased AA.
