Mandatory lockdown impairs performance in professional soccer players.

COVID-19 caused a total halt in sport competition during 2020. The purpose of this study was to analyze the changes between pre- and post-lockdown competitive periods in the players’ workload variables in competition. Seventeen professional football players were monitored using a WIMU PRO® inertial device throughout the 2019-20 season. Anthropometric and physical fitness were assessed with the aim to relate possible associations between these characteristics and the workload changes in the pre- and post-lockdown periods. During the lockdown, players carried out an 8-week guided self-training. There was a general decrement in the players’ physical workload demands in competition, and the parameters related to high-intensity actions as accelerations and decelerations (-8.96% [ES: 0.64] and -11.04% [ES: 0.77] respectively; p < .05), Ind HSR (-35.57% [ES: 0.92]; p = .002), HMLD (-8.58% [ES: 0.66]; p = .016), PLOAD (-7.03% [ES: 0.54]; p = .047) and Vmax (-3.80% [ES: 0.65]; p = .016) can be highlighted. The results showed high negative correlations between match workload variables prior to the lockdown and the percentage of change in these variables after the lockdown period. Individual percentages of change showed high variability in players’ changes. Individual self-training programs should be reviewed to minimize the impact of a “detraining” period in players’ physical performance during possible new lockdown periods.

Hubungan Beban Kerja Perawat Dengan Upaya Pencegahan Hais Pada Masa Pandemi Covid 19 di Rumah Sakit Pertamina Bintang Amin Bandar Lampung

ABSTRACT: RELATIONSHIP OF NURSES WORKLOAD WITH HAIS PREVENTION EFFORT DURING THE COVID-19 PANDEMIC AT PERTAMINA BINTANG AMIN HOSPITAL BANDAR LAMPUNG Introduction: The incidence of menstruation is still high, one of the factors is the relatively high workload of nurses. excessive workload on nurses can trigger stress and burnout. Nurses who experience stress and burnout allow them to not be able to perform effectively and efficiently because their physical and cognitive abilities are reduced which may occur due to an imbalance between the number of patients and the number of nurses working in the hospital. Based on the results of the pre-survey, the comparison of the workload of nurses at Pertamina Bintang Amin Hospital Bandar Lampung and dr. A. Dadi Tjokrodipo by distributing questionnaires to 15 nurses in each hospital. At the hospital. Pertamina Bintang Amin showed that nurses experienced a physical workload of 7 nurses (46.6%) with a score of 27-54, and a mental workload of 8 nurses (53.3%) with a score of > 57. Meanwhile, RSUD dr. A. Dadi Tjokrodipo, the results showed that nurses experienced a physical workload of 5 nurses (33.3%) with a score of 27-54, and a mental workload of 6 nurses (40%) with a score of > 57.Objective: to find out the relationship between the workload of nurses and efforts to prevent HAIs during the Covid 19 pandemic at Pertamina Bintang Amin Hospital Bandar Lampung in 2021Methods: This type of research is a quantitative, cross-sectional design. The population and sample were 110.1 respondents, which were rounded up to 111 respondents.

Association between occupational physical activity and quantitative bone ultrasound in sawmill workers

A small number of studies have examined the relationship between bone health and level of physical load. We explored the effect of occupational physical activity on skeletal status in younger sawmill workers using ultrasonic indices of bone density. In a cross-sectional study, we measured bone density with quantitative ultrasound (QUS) in 128 sawmill workers (89 men and 39 women), mean age 39.1 +/- 10.8 years. Back strength was measured by dynamometry. Information on occupational and leisure physical activity, joint pain, education and smoking were obtained with the questionnaire. All QUS bone parameters and back strength were significantly higher in men than in women. A T score for quantitative ultrasound index (QUI) of − 2.2 or lower was found only in two men and one women. QUI did not significantly differ based on presence of parameters of physical occupational activity (carrying loads exceeding 5 kg, repetitive movements, physical exertion while working and non-sitting position at work). When controlling for age, gender and body mass index, participants with higher smoking index had significantly lower QUI (p=0.004). Physical workload was not significantly associated with QUI. In our working population, some lifestyle habits, such as smoking, had a greater impact on bone health than physical occupational activity.

The impact of musculoskeletal pain and strenuous work on self-reported physical work ability: a cohort study of Swedish men and women

Objective We investigated the separate and combined effects of musculoskeletal pain (MSP) and strenuous work (heavy physical workload (PWL)/low-decision authority) on poor physical work ability (WA). Methods This study uses baseline data from the 2010 Stockholm Public Health Questionnaire (SPHQ) including 9419 workers with good physical WA. Exposure to PWL and decision authority were estimated using sex-specific job-exposure matrices linked to occupations. Exposures (high/low) were combined with the presence of MSP. Follow-up data on physical WA were taken from the 2014 SPHQ and dichotomised (the responses: “moderate”, “rather poor” and “very poor” indicated poor WA). Logistic regression models calculated sex-specific odds ratios adjusting for age, education and health and lifestyle factors. Interaction between MSP and strenuous work was examined using the synergy index (SI). Analyses were conducted using SPSS.27. Results MSP, heavy PWL and low-decision authority were separately associated with poor WA. MSP was associated with higher odds of poor WA than strenuous work for women, the opposite for men. Combinations of MSP and strenuous work often resulted in higher risks of poor WA than when adding the effects of the single exposures (e.g., MSP and heavy PWL men: AOR 4.04 95% CI 2.00–8.15, women: AOR: 3.25 95% CI 1.81–5.83). The SI was non-significant for both sexes. Conclusion Workers with MSP and strenuous work often had higher risks of poor WA than would be expected from adding the effects of the single exposures. To decrease poor WA in this group, strenuous work should be lowered, and MSP addressed in workplaces.

An Analysis of Acceleration, Deceleration and High-Intensity Skating during Elite Bandy Match-Play: A Case Study

Profiles of physical workload in sports are useful to optimize performance and reduce the risk of injury. The aim of the study was to investigate physical workload in 10 elite bandy players by describing acceleration, deceleration, and high-intensity skating during bandy match-play. During 13 home matches, 10 male elite bandy players wore a GPS unit to measure changes in the total distance, total distance skating in two speed zones, and total distance of acceleration and deceleration. A within-subject design was used to measure changes over time during match-play by comparing first and second halves as well as comparisons for consecutive 15 min intervals. No significant differences were observed for high-intensity or very high-intensity acceleration and deceleration for comparisons by halves or for 15-min intervals. For comparisons by halves, a significant time-dependent effect was observed on very fast skating (1337.6 m vs. 1160.9 m), sprint skating (300.0 m vs. 272.0 m), low-intensity acceleration (342.7 m vs. 333.0 m), and total distance covered (10,916.9 m vs. 10,450.3 m). These variables, along with low-intensity deceleration, were also significant for the 15 min interval comparisons. The results show that there is no time-dependent reduction in high-intensity acceleration and deceleration in elite bandy match-play. However, elite bandy players do not maintain the distance of high-intensity skating throughout a whole match.

Enabling Immersive Exercise Activities for Older Adults: A Comparison of Virtual Reality Exergames and Traditional Video Exercises

Participating in cognitive and physical activities can help older adults to live a healthy and independent life. However, with the ongoing pandemic, face-to-face training options became unavailable or limited, yielding a need for alternatives. In this paper, we conducted a user study with older adults (N = 25) to compare a traditional, recorded 2D gymnastics video with an immersive virtual reality (VR) exergame. We evaluated the movement and heart rate of the participants, as well as their enjoyment, attention to the task, and perceived workload. In the VR condition, we additionally assessed their feeling of cybersickness. Finally, qualitative feedback about their preferences was collected. The results indicate that our immersive VR exergame can be a suitable alternative, but not a replacement for traditional 2D video-based exercise activities. Furthermore, the cognitive aspect of exergames can lead to the feeling of physical workload, even if easy movements are performed. Finally, we discuss the implications of our results for future VR exergames and point out advantages and disadvantages of the systems.

Systematic Review of Back-Support Exoskeletons and Soft Robotic Suits

Lower back pain and musculoskeletal injuries are serious concerns for workers subjected to physical workload and manual material handling tasks. Spine assistive exoskeletons are being developed to support the spine and distribute the spine load. This article presents a detailed up-to-date review on the back support exoskeletons by discussing their type (Active/Passive), structure (Rigid/Soft), power transmission methods, weight, maximum assistive force, battery technologies, tasks (lifting, bending, stooping work), kinematic compatibility and other important features. This article also assesses the back support exoskeletons in terms of their ability to reduce the physical load on the spine. By reviewing functional and structural characteristics, the goal is to increase communication and realization among ergonomics practitioners, developers, customers, and factory workers. The search resulted in reviewing 34 exoskeletons of which 16 were passive and 18 were active. In conclusion, back support exoskeletons have immense potential to significantly reduce the factors regarding work-related musculoskeletal injuries. However, various technical challenges and a lack of established safety standards limit the wide adaptation of exoskeletons in industry.

The effects of using an ergonomic aid on the physical workload and body discomfort reported by pre-adolescent farmers in West Bengal, India

BACKGROUND: Musculoskeletal disorders are one of the major health hazards among farmers. Pre-adolescents are mainly associated with agricultural work due to poor socioeconomic conditions. OBJECTIVES: This study aims to implement a new ergonomics aid for the betterment of job procedures and improvement of productivity, health, and safety of the preadolescent farmers. METHODS: 100 male and 100 female preadolescent farmers were randomly selected from the villages of Tarakeswar, West Bengal, India, to evaluate and reduce work-related musculoskeletal disorders, physiological stress. Modified Nordic questionnaires, Body Part Discomfort (BPD) scale, and handgrip strength were assessed before and after using the ergonomics aid. RESULTS: The results of the study show that there was a significant change (decrease) in discomfort in the lower back, wrists, shoulder, and hands among preadolescent farmers when using the newly designed ergonomic aid. Handgrip strength increased and physiological stress was decreased among preadolescent farmers in post-intervention than pre-intervention in just after work conditions. Productivity has been increased in farming by decreasing absenteeism from work with the use of ergonomic aid. CONCLUSION: This study concludes that productivity has been increased in farming by decreasing absenteeism from work as well as by using the ergonomic aid the discomfort feeling has been decreased markedly.
