Gelatinases and physical exercise: A systematic review of evidence from human studies
2017
Background Matrix metalloproteinases (MMPs), particularly gelatinase A (MMP-2) and gelatinase B (MMP-9), as well as their tissue inhibitors (TIMP-1 and TIMP-2), are involved in the development of skeletal muscle tissue, in the repair process after muscle injury and in the adaptive modifications induced by physical exercise in skeletal muscle. This paper aims at reviewing results from human studies that investigated the role of gelatinases and their inhibitors in skeletal muscle response to acute physical exercise or training. Methods Electronic databases PubMed/MEDLINE, Scopus and Web of Science were searched for papers published between January 2000 and February 2017. The papers were eligi…
Effects of vigorous late-night exercise on sleep quality and cardiac autonomic activity
2011
Sleep is the most important period for recovery from daily load. Regular physical activity enhances overall sleep quality, but the effects of acute exercise on sleep are not well defined. In sleep hygiene recommendations, intensive exercising is not suggested within the last 3 h before bed time, but this recommendation has not been adequately tested experimentally. Therefore, the effects of vigorous late-night exercise on sleep were examined by measuring polysomnographic, actigraphic and subjective sleep quality, as well as cardiac autonomic activity. Eleven (seven men, four women) physically fit young adults (VO(2max) 54±8 mL·kg(-1)·min(-1) , age 26±3 years) were monitored in a sleep labor…
The Italian paediatric society raccomandations on children and adolescents extra-domestic activities during the SARS COV-2 emergency phase 2
2020
Abstract Background Due to novel coronavirus infection emergency, restricting measures have been imposed in Italy. As well as adults, also children are limited in their daily routine. Main text As the lockdown period is expected to end on 3rd May 2020, we discuss the opportunity for children to practice safely recreational or physical activity outdoor. Conclusion The Italian Paediatric Society recommends specific recreational and physical activities according to the age of the children and respecting social distancing.
Laboratory medicine and sports : between Scylla and Charybdis
2012
Laboratory medicine is complex and contributes to the diagnosis, therapeutic monitoring and follow-up of acquired and inherited human disorders. The regular practice of physical exercise provides important benefits in heath and disease and sports medicine is thereby receiving growing focus from almost each and every clinical discipline, including laboratory medicine. Sport-laboratory medicine is a relatively innovative branch of laboratory science, which can provide valuable contributions to the diagnosis and follow-up of athletic injuries, and which is acquiring a growing clinical significance to support biomechanics and identify novel genomics and "exercisenomics" patterns that can help i…
Designing Affordances for Health-Enhancing Physical Activity and Exercise in Sedentary Individuals
2016
Ideas in ecological dynamics have profound implications for designing environments that offer opportunities for physical activity (PA), exercise and play in sedentary individuals. They imply how exercise scientists, health professionals, planners, designers, engineers and psychologists can collaborate in co-designing environments and playscapes that facilitate PA and exercise behaviours in different population subgroups. Here, we discuss how concepts in ecological dynamics emphasise the person-environment scale of analysis, indicating how PA environments might be (re)designed into qualitative regions of functional significance (affordances) that invite health-enhancing behaviours according …

Muscle strength according to level of physical exercise and educational background in middle-aged women in Finland.
1992
The aim of this study was to examine the role of socio-economic status and the practice of physical exercise in explaining variation in muscle strength in 50 to 60-year-old women. Consequently, four study groups combining education and physical activity were formed: (1) university education, physically active; (2) university education, sedentary; (3) vocational or lower level of education, physically active; (4) vocational or lower level of education, sedentary. Maximal isometric strength of hand grip, arm flexion, body flexion and extension as well as dynamic power of the abdominal muscles were measured in 112 women. The results of the maximal isometric strength measurements were standardi…
Muscle strength and history of heavy manual work among elderly trained women and randomly chosen sample population.
1993
The association between a history of heavy work and muscle strength was studied among 51 physically active women aged 66–85 years trained in sports and 41 women aged 70–81 years selected randomly from the population register. Maximal isometric muscle strength of hand grip, arm flexion, leg extension and trunk flexion and extension were measured using specially constructed dynamometers. The capacity of the abdominal muscles was evaluated by means of a sit-up test. The study included an interview dealing with the subjects' histories of heavy manual employment. The mean histories of heavy work for the trained and untrained women were 24 and 36 years, respectively. The trained women showed sign…
Lift weights to fight overweight
2014
Although resistance training (RT) has long been accepted as a means for developing and maintaining muscular strength, endurance, power and muscle mass, its beneficial relationship with health factors and chronic disease has only recently been recognized in the scientific literature. Prior to 1990, resistance training was not a part of the recommended guidelines for exercise training and rehabilitation for either the American Heart Association or the American College of Sports Medicine (ACSM). In 1990, the ACSM recognized resistance training as a significant component of a comprehensive fitness programme for healthy adults of all ages, a position subsequently confirmed few years after. At pr…
Comparison between logbook-reported and objectively-assessed physical activity and sedentary time in breast cancer patients: an agreement study
2017
BACKGROUND: Increasing physical activity (PA) and decreasing sedentary time (ST) have important health effects among breast cancer patients, a growing population group. PA and sedentary behaviors are complex multi-dimensional behaviors and are challenging to monitor accurately. To date few studies have compared self-reports and objective measurement in assessing PA and ST in women undergoing breast cancer treatments. The aim of the present study was to compare self-reports and objective measures for assessing daily time spent in moderate-intensity physical activity (MPA), vigorous-intensity physical activity (VPA) and ST in women undergoing breast cancer treatments. METHODS: Baseline data f…
