A systematic review of physical fitness, physiological demands and biomechanical performance in equestrian athletes
2012
This article presents a systematic review of the literature investigating physical fitness, physiological demands and biomechanical performance in equestrian athletes. Three databases (SportsDiscus, CAB abstracts and PubMed) were searched to identify the literature. The main search term of ‘horse-riding’ was combined with eleven specific keywords (‘fitness’, ‘physiology’, ‘biomechanics’, ‘equestrian’, ‘athlete’, ‘co-ordination’, ‘heart rate’, ‘oxygen consumption’ ‘kinematic’ ‘EMG’ and ‘skill’). Exclusion criteria were: conference proceedings, abstracts, theses, and non-peer reviewed articles. Subsequently, 15 peer-reviewed papers were identified and included within this review. The main re…
The story models of physiotherapy students’ professional development. Narrative research
2014
The aim of this article is to investigate students’ narratives about their professional development process. This research brings new kind of knowledge to continuing learning, developing education and planning the curriculum in physiotherapy education. The European Qualification Framework (EQF) defines learning competences in education; qualitative research has a narrative approach. The material consists of eight voluntarily participating physiotherapy students’ portfolios written during their whole study time. The longitudinal data describes them as learners and their development process. The major findings are four main episodes in professional development: the previous studies, a new way…
Kinematics of shoulder abduction in the scapular plane
1995
In this paper the kinematics of arm abduction in the scapular plane of 38 healthy experimental subjects is reported. The ratio of the glenohumoral and the scapulothoracic components of the motion were determined and the influence of the abduction speed and of the external load on it were investigated. The investigation of the effect of abduction speed involved all 38 subjects. Each of them performed one slow and one fast abduction. Statistical analysis showed that there were large differences between individuals, but that for any one individual the abduction process is essentially reproducible. For the one individual there is a strong, linear relationship between glenohumeral and scapulotho…

The controversial relationship between exercise and atrial fibrillation: clinical studies and pathophysiological mechanisms
2015
Atrial fibrillation is the most common clinically significant arrhythmia observed both in the general population and in competitive athletes. The most important risk factors are all preventable by regular physical activity. However, although the benefits of moderate physical activity in controlling cardiovascular risk factors and decreasing the risk of atrial fibrillation have been extensively proved, concerns have arisen about the potential negative effects of vigorous exercise, particularly in endurance athletes. Furthermore, in a subset of patients with atrial fibrillation younger than 60 years, routine evaluation does not reveal any cardiovascular disease or any other known causal facto…
Power of lower extremities and age were the main determinants on the agility test for adults in a cohort of men aged 66–91 years
2019
Study Design: Cross-sectional study. Objective: To evaluate the relationship between agility and personal factors, muscle strength and power, mobility, self-reported balance and physical activity among older men. Methods: Agility was measured by using the Agility Test for Adults (ATA). We studied 100 Finnish male former elite athletes (endurance n = 50; power n = 50) and 50 matched controls aged 66 to 91 years (mean age 75.5 years). The associations between agility and other variables were similar between three groups; thus, multiple linear regression analyses were done by using the pooled data of the participants. Results: On the basis of multiple linear regression analyses, combination of…
Epidemiological, biological and clinical update on exercise-induced hemolysis
2019
Exercise-induced hemolysis can be conventionally defined as rupture and destruction of erythrocytes during physical exercise. The currently available epidemiologic information attests that a substantial degree of exercise-induced hemolysis is commonplace after short-, medium-, long- and ultra-long distance running, as reflected by significant decrease of serum or plasma haptoglobin and significant increase of plasma concentration (or overall blood content) of free hemoglobin. This paraphysiological intravascular hemolysis is typically mild (average variations of hemolysis biomarkers are usually comprised between 1.2- and 1.8-fold), almost self-limiting (completely resolving within 24-48 hou…
Proximale Verankerung von Hüft-Endoprothesen mit poröser Oberfläche: 6-Jahres-Ergebnisse
2008
PROBLEM The anatomically shaped pcl (ESKA) total hip replacement has a porous coating of the proximal stem and the cup to allow for bony ingrowth. The tip of the stem is polished. METHOD We report the results of 96 THR 6.2 years (5.25-6.7) after implantation. RESULTS There were no revisions during this period. One stem showed radiographic loosening at follow-up. There was stress-shielding in 9.4% in contrast to the concept of proximal fixation. Thigh-pain was found in 9.4%. One patient demonstrated disabling thigh-pain despite radiologic bony ingrowth. By drilling the femur distal to the tip of the stem a remarkable relief was achieved. CONCLUSION Despite numerous cases of stress-shielding …
Minimal invasive posterior correction of Lenke 5C idiopathic scoliosis: comparative analysis of minimal invasive vs. open surgery
2019
Introduction Surgical management of adolescent idiopathic scoliosis in spite of usually favourable outcomes is still a major operation. Therefore, efforts are being undertaken to minimalize the procedure, reduce the surgical trauma and postoperative convalescence. The study was designed to compare posterior minimal invasive surgery using navigation based on intraoperative 3D imaging and standard open instrumented fusion in Lenke 5C idiopathic scoliosis treatment. Materials and methods From eight patients with Lenke 5C curves planned for posterior correction and instrumented fusion, four were treated with minimally invasive and four had open procedure. Operation length, estimated blood loss,…
Effects of aquatic and dry land resistance training devices on body composition and physical capacity in postmenopausal women.
2013
Effects of Aquatic and Dry Land Resistance Training Devices on Body Composition and Physical Capacity in Postmenopausal Women To determine the effects of a supervised strength training program on body composition and physical capacity of older women using three different devices: weight machines, elastic bands, and aquatic devices that increase drag forces (ADIDF). Four groups were formed: control group, weight machine group (WMG), elastic band group (EBG) and a group that used ADIDF (ADIDFG). Body composition and physical capacity were assessed before and after the intervention period. The ADIDFG showed improvements in fat mass (FM), fat-free mass of the left arm (FFM-LA) and right arm (FF…
