Physical Activity Levels and Related Energy Expenditure during COVID-19 Quarantine among the Sicilian Active Population: A Cross-Sectional Online Sur…

2020

Background: During the coronavirus disease 2019 (COVID-19) pandemic, the Italian government has adopted containment measures to control the virus’s spread, including limitations to the practice of physical activity (PA). The aim of this study was to estimate the levels of PA, expressed as energy expenditure (MET–minute/week), among the physically active Sicilian population before and during the last seven days of the COVID-19 quarantine. Furthermore, the relation between this parameter and specific demographic and anthropometric variables was analyzed. Methods: 802 Sicilian physically active participants (mean age: 32.27 ± 12.81 years; BMI: 23.44 ± 3.33 kg/m2) were included in the study and…

Validity and reliability of the motivation for physical activity (RM4-FM) questionnaire

2021

There is a lack of validated instruments measuring motivation for physical activity (RM4-FM) in the Finnish language. The study examined the translated RM4-FM instrument’s psychometric properties in a sample of healthy, older Finnish adults. RM4-FM was translated and linguistically validated adhering to published guidelines. 65–75-year olds (n=102), completed the RM4-FM, the physical activity acceptance questionnaire (PAAQ) and sociodemographic characteristics questionnaires electronically. The RM4-FM was readministered one month after the initial assessment. RM4-FM translated well into Finnish. Motivation dimension scores were skewed towards high internal and low external motivation. A flo…

Stress and physical activity during a 1-year counseling intervention

2013

TIIVISTELMÄ Schildt, Kasimir Ario Vilhelm 2013. Stressi ja fyysinen aktiivisuus vuoden mittaisen neuvonta intervention aikana. Liikuntafysiologian Pro gradu -tutkielma. Liikuntabiologian laitos. Jyväskylän yliopisto. 83 sivua. Liikkumattomuus on luokiteltu maailman neljänneksi suurimmaksi kuolinsyyksi ja arviolta 3,2 miljoonaa ihmista kuolee vuosittain liikkumattomuudesta seuraaviin sairauksiin. Samaan aikaan ihmisten kokema stressi on lisääntynyt. Monissa aiemmissa tutkimuksissa fyysisen aktiivisuuden lisääminen on helpottanut stressiä. Tämän tutkimuksen tarkoitus oli selvittää, ovatko fyysinen aktiivisuus ja inaktiivisuus yhteydessä koettuun ja sykevälivaihtelun avulla mitattuun stressiin…

Children’s physical activity and sedentary time compared using assessments of accelerometry counts and muscle activity level

2018

Background This research compared accelerometry (ACC)-derived and muscle electromyography (EMG)-based estimates of physical activity (PA) and sedentary time in typical PA tasks and during the daily lives of children. Methods Data was included from two exploratory studies. In Study I, 6–7-year-old children (n = 11, 64% girls) were assessed for eight PA tasks (walking, stair negotiation, climbing, crawling, swinging, balancing, trampoline jumping and a game of tag). In Study II, 7–9-year-old children (n = 14, 38% girls) were assessed for six PA tasks (walking, sitting, static squat, single leg hops, jump for height and standing long jump), and daily PA during one day with and one day without…

Do Running and Strength Exercises Reduce Daily Muscle Inactivity Time?

2016

Understanding how a specific exercise changes daily activity patterns is important when designing physical activity interventions. We examined the effects of strength and interval running exercise sessions on daily activity patterns using recordings of quadriceps and hamstring muscle electromyographic (EMG) activity and inactivity. Five male and five female subjects taking part in a 10-week training programme containing both strength and interval running training sessions were measured for daily muscle EMG activities during three days: on a strength day, an interval running day, and a day without exercise. EMG was measured using textile electrodes embedded into sport shorts that were worn 9…

Muscle inactivity is adversely associated with biomarkers in physically active adults.

2015

PURPOSE While the lack of muscular activity is a proposed trigger for metabolic alterations, this association has not been directly measured. We examined the associations between EMG-derived muscle inactivity and activity patterns and cardiometabolic biomarkers in healthy, physically active adults. METHODS Data for this cross-sectional study were pooled from two studies (EMG24 and InPact), resulting in a sample of 150 individuals without known chronic diseases and with high-quality EMG data (female n = 85, male n = 65, age = 38.8 ± 10.6 yr, body mass index = 23.8 ± 3.1 kg·m⁻²). EMG was measured during one to three typical weekdays using EMG shorts, measuring quadriceps and hamstring muscle …

Convenience Behavior and Being Overweight in Adults: Development and Validation of the Convenience Behavior Questionnaire

2019

The etiology of overweight and obesity is a mixture of genetic determinants, environmental factors, and health behaviors. Especially intra- and interpersonal inactive behaviors, here termed convenience, seems to play an important role. The objective was to develop and validate the Convenience Behavior Questionnaire (CBQ) to assess convenience-related items and their association with overweight and obesity in a large population. A sample of 1233 subjects aged 18–82 years from six population groups took part in a self-administered questionnaire. Test-retest reliability was estimated and the independent association between convenience-related items and overweight and obesity was investigated. …

Decreasing muscle performance associated with increasing disease activity in patients with rheumatoid arthritis

2018

Objectives Increasing evidence suggests that inflammation has a detrimental effect on muscle strength. Our objective was to analyse the association between muscle performance and different disease activity levels in patients with rheumatoid arthritis (RA). Method A total of 199 consecutive outpatients were subject to cross-sectional assessment. Measurements of grip strength, endurance of the upper and lower limbs and trunk strength were combined as a muscle performance composite score (MPCS), using a standardised method. The disease activity for 28 joints (DAS28), radiographs of small joints (Larsen score), rheumatoid factor, body mass index (BMI), comorbidities and anti-rheumatic drugs wer…

Quadriceps and hamstring muscle EMG activity during a football match

2012

Roudi Kalema (2012). Quadriceps and hamstring muscle EMG activity during a football match. Department of Biology of Physical, University of Jyvaskyla. Master’s Thesis in Exercise Physiology. 58 pages. Fatigue represents a reduction in the ability of muscle to generate force and in the context of football, it has been often related with injury. Surface electromyography is a valuable technique for evaluating muscle activation and fatigue but it has never been applied during a football match. The development of washable textile electrodes has opened up possibilities to investigate muscular activity in non-laboratory settings, without skin preparation and wires hanging around the body. It has a…
