LONGITUDINAL TRACKING OF MUSCULAR POWER CHANGES OF NCAA DIVISION I COLLEGIATE WOMEN GYMNASTS
2004
Gymnastics relies upon power as a critical component of sports-specific fitness. The purpose of this study was to monitor long-term training adaptations in the power of National Collegiate Athletics Association Division I women gymnasts. Twenty members of a women's gymnastic team (aged 18-22) were tracked over 3 years with the first year a baseline year of testing. Whole body power for the counter-movement (CMJ) and squat (SJ) vertical jump was obtained via force plate analyses at 2 assessment time points during each year (February and November). Results showed significant (p < or = 0.05) and continued increases in peak power output in the CMJ and SJ at each biannual assessment. Improvement…
Fundamental movement skills and physical fitness as predictors of physical activity: A 6-year follow-up study
2015
The purpose of this study was to examine the extent to which fundamental movement skills and physical fitness scores assessed in early adolescence predict self-reported physical activity assessed 6 years later. The sample comprised 333 (200 girls, 133 boys; M age = 12.41) students. The effects of previous physical activity, sex, and body mass index (BMI) were controlled in the main analyses. Adolescents’ fundamental movement skills, physical fitness, self-report physical activity, and BMI were collected at baseline, and their self-report energy expenditure (metabolic equivalents: METs) and intensity of physical activity were collected using the International Physical Activity Questionnaire …
Comparing Performance of Ensemble-Based Machine Learning Algorithms to Identify Potential Obesity Risk Factors from Public Health Datasets
2021
Societal factors such as globalization, supermarket growth, rapid unplanned urbanization, sedentary lifestyle, economical distribution, and social position gradually develop behavioral risk factors in humans. Behavioral risk factors are unhealthy habits (consumption of tobacco and alcohol), improper diet (consumption of high calorific discretionary fast foods, sweet beverages), and physical inactivity. The behavioral risks may lead to physiological risks, body–energy imbalance. Obesity is one of the foremost lifestyle diseases that leads to other health conditions, such as cardiovascular disease (CVDs), chronic obstructive pulmonary disease (COPD), cancer, diabetes type II, hypertension, an…
Vaccination Coverage Increase among Adolescent and Young Adults of the Palermo District (Italy) as a Result of a Public Health Strategy to Contrast a…
2018
During summer 2016 in the District of Palermo, Italy, the rapid succession of four cases of invasive meningococcal disease among young adults, with one death, have had an extraordinary emphasis by Local and National mass media. The resultant &ldquo;epidemic of panic&rdquo; among general population overloaded vaccination Units of the Palermo District during following months. Strategies implemented by Sicilian and Local Public Health Authorities to counteract &ldquo;meningitis fear&rdquo; were: a) extension of active and free of charge anti-meningococcal tetravalent vaccination from age class 12&ndash;18 to 12&ndash;30 years old; b) implementation of vaccination units …
A study of hurdles in mass treatment of schistosomiasis in KwaZulu-Natal, South Africa
2015
Background: It has been estimated that 700 million people worldwide and 5.2 million people in South Africa are in need of annual treatment for schistosomiasis. In accordance with the current policy the Department of Health (DoH) in KwaZulu-Natal province, South Africa, aimed to reach 75% treatment coverage in a mass treatment campaign (MTC) of schools in a schistosomiasis-endemic area.Methods: A cross-sectional study was designed to explore the implementation, coverage, challenges and limitations of a DoH MTC in a middle-income country. The study was conducted by exploring nurses’ and research team records, school enrolment lists and parental consent forms.Results: Slightly more than 10 000…
Physical exercise and sarcopenia in older people: position paper of the Italian Society of Orthopaedics and Medicine (OrtoMed)
2015
Sarcopenia is the age-associated loss of skeletal muscle mass and function. It is a major clinical problem for older people and research in understanding of pathogenesis, clinical consequences, management, and socioeconomic burden of this condition is growing exponentially. The causes of sarcopenia are multifactorial, including inflammation, insulin resistance, changing endocrine function, chronic diseases, nutritional deficiencies and low levels of physical activity. Operational definition of sarcopenia combines assessment of muscle mass, muscle strength and physical performance. The diagnosis of sarcopenia should be based on having a low appendicular fat free mass in combination with low …
Maximal isometric muscle strength and anthropometry in 75-year-old men and women in three Nordic localities
2007
Isometric maximal strength of hand grip, elbow flexion, knee extension, trunk extension and trunk flexion was studied in representative samples of 75-year-old residents of 3 Nordic localities: Glostrup in Denmark, Gothenburg in Sweden and Jyvaskyla in Finland. The study forms a part of a wider comparative research project analyzing the functional capacity and health of 75-year-olds in these towns. The strength measurements were carried out using standardized techniques and identical dynamometers. The results showed that the strength values of the limb muscles were significantly lower among the 75-year-olds in Jyvaskyla, both in absolute values and in relative units (N/kg body mass). For the…
Sonographische Charakteristika laterozervikaler Raumforderungen
2001
UNLABELLED Sonography of the head and neck mainly focuses on tumours of the lateral neck. Even though most of these masses are enlarged lymph nodes, other tumors have to be considered. AIM To determine whether different pathological cervical masses display a characteristic sonographic morphology. METHOD On the basis of 530 sonographical findings in the neck, typical ultrasound characteristics either in B-scan or in colour coded sonography were demonstrated. RESULTS Apart from enlarged lymph nodes, it was possible to differentiate other occurrences such as branchial cysts, abscesses, laryngoceles, lipomas, neurinomas, glomus tumours, paragangliomas and also fibromas by their specific ultraso…
Intraosseous gas distribution as a marker of postmortem interval
2020
Abstract The postmortem interval is probably the most important puzzle piece in clarifying the circumstances in case of death occurred in unknown conditions. Over the years, radio-imaging modalities have proved their worth in forensic field, providing additional and significant improvements and findings. CT-scan is characterized by wide availability, fast scan times and sustainable healthcare costs. Detection of gas, hemorrhage and bone fractures are points of strength of CT-scan. A reliable evaluation of the post-mortem interval is interesting in the victims of a mass disaster, also following a natural disaster, for the individuation of responsibility in the efficiency of the help and assi…
New Trends in the Treatment of Osteoporosis
1998
Osteoporosis is “a systemic disease characterized by a reduction in bone mass and a microarchitectonic alteration of the skeleton, with a consequent increase in skeleton fragility and susceptibility to fractures”, as defined by the last Consensus Development Conference1. With this definition, the alteration in skeletal structure, which is not yet easy to evaluate, becomes an important factor determining the risk of fracture of the osteoporotic patient, in addition to the bone mass, which to certain limit can be easily evaluated. This is an aspect that may create some problems at the time of taking a decision on how to proceed with a subject with decreased bone mass. Currently, the measureme…
