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…
Reliability of isokinetic assessment of shoulder-rotator strength: a systematic review of the effect of position.
2011
Context:Isokinetic assessment of shoulder internal- (IR) and external-rotator (ER) strength is commonly used with many different postures (sitting, standing, or supine) and shoulder positions (frontal or scapular plane with 45° or 90° of abduction).Objective:To conduct a systematic review to determine the influence of position on the intersession reliability of the assessment of IR and ER isokinetic strength, to identify the most reliable position, and to determine which isokinetic variable appears to be most stable in intersession reliability.Evidence Acquisition:A systematic literature search through MEDLINE and Pascal Biomed databases was performed in October 2009. Criteria for inclusion…
LDL size and subclasses in patients with abdominal aortic aneurysm
2009
Abstract Since the type of dyslipidemia in patients with abdominal aortic aneurysm (AAA) is still insufficiently defined, we measured plasma lipids and analyzed LDL size and subclasses by gradient gel electrophoresis in 30 male patients (69±6 years, BMI: 27±3) with newly diagnosed AAA and in 26 age- and BMI-matched male healthy controls. Patients with AAA had lower HDL-cholesterol ( p p =.0002) and smaller LDL size ( p p =.0210) in relation to controls. Multivariate analysis also showed that small LDL size was independently associated with the presence of AAA ( p =.0350). Increased levels of small, dense LDL may therefore represent a common feature in patients with AAA.
Primary intra and extradural solitary fibrous tumor/hemangiopericytoma of thoracic spine with paravertebral intrathoracic spread: Case report and rev…
2020
Abstract Solitary fibrous tumors/hemangiopericytomas (SFTs/HPCs), constitute 1% of all CNS tumors. Spinal SFTs/HPCs are extremely rare. To date, few retrospective studies and case reports of primary spinal SFTs/HPCs have been published in the literature. We report clinical and radiological presentation, surgical treatment, and post-operative outcome at three years follow-up of a rare case of primary spinal intra and extradural SFT/HPC of thoracic spine with dumbbell shaped paravertebral intrathoracic spread and multidirectional erosion of the bone. A 73-year-old female presented with progressive lower limbs weakness and hypoesthesia below the rib cage. MRI showed an irregular isointense T5-…
Training Volume and Intensity of Physical Activity among Young Athletes: The Health Promoting Sports Club (HPSC) Study
2019
Both training volume and overall physical activity (PA) play a role in young athletes’ sports performance and athletic development. The purpose of this study was to describe the training volume and PA of young athletes in endurance, aesthetics, ball games, and power sports. Questionnaire data (n = 671) were obtained from 15-year-old Finnish athletes on sports participation, along with accelerometer data (n = 350) assessing the amount and intensity of their PA. The athletes’ mean weekly training volume was 11 h 41 min. Objectively assessed PA amounted to 4 h 31 min daily, out of which 1 h 31 min was at a level of moderate-to-vigorous intensity (MVPA). Among 24% of the athletes, the weekly tr…
Neuromuscular Training Warm-up Prevents Acute Noncontact Lower Extremity Injuries in Children’s Soccer : A Cluster Randomized Controlled Trial
2021
Background: Prevention of sports injuries is essential in youth, as injuries are associated with less future physical activity and thus greater all-cause morbidity. Purpose: To investigate whether a neuromuscular training warm-up operated by team coaches is effective in preventing acute lower extremity (LE) injuries in competitive U11-U14 soccer players. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: Twenty top-level U11 to U14 soccer clubs in Finland were randomized into intervention and control groups and assessed for 20 weeks. Participants included 1403 players (280 female, 1123 male; age range, 9-14 years): 673 players (44 teams) in the intervention group and …
Validation of two short questionnaires assessing physical activity in colorectal cancer patients
2018
Background In order to investigate the impact of adherence to recommendations of physical activity and sedentary time on health outcomes in clinical trials, there is a need for feasible tools such as questionnaires that can give representative estimates of these measures. The primary aim of the present study was to validate two such questionnaires and their ability to estimate adherence to the recommendations of physical activity defined as moderate-to- vigorous physical activity or moderate physical activity of at least 150 min/week in colorectal cancer patients. Secondarily, self-reported sedentary time from the HUNT-PAQ was also evaluated. Methods Participants from 'The Norwegian dietary…
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 …
Do adolescents with long-term illnesses and disabilities have increased risks of sports related injuries?
2017
peer-reviewed Background: The aim of this study is to examine the rates of sports related injuries in adolescents based on the severity of their long-term illnesses or disabilities (LTID). Few injury prevention strategies in sports and health promotion have explored disaggregation by disability. Methods: Data obtained from the 2014 Finnish Health Behaviour in School-aged Children survey (n = 3716, mean age = 14.8, SD = 1.03) were grouped into adolescents with and without LTID. A further indicator or severity was determined when adolescents reported their LTID affected their participation (affected LTID). Odds ratio (95% CI) were used to determine the associations between sports related inju…
