Heavy Resistance Training in Breast Cancer Patients Undergoing Adjuvant Therapy.
2019
BACKGROUND AND PURPOSE Adjuvant breast cancer therapy may reduce maximal muscle strength, muscle mass, and functional performance. Although maximal strength training (MST) has the potential to counteract this debilitating outcome and is shown to be superior to low- and moderate-intensity strength training, it is unknown if it can elicit effective adaptations in patients suffering treatment-induced adverse side effects. METHODS Fifty-five newly diagnosed stage I to III breast cancer patients (49 ± 7 yr) scheduled for adjuvant therapy were randomized to MST or a control group. The MST group performed 4 × 4 repetitions of dynamic leg press at approximately 90% of one-repetition maximum (1RM) t…
The effects of assisted and resisted plyometric training on jump height and sprint performance among physically active females
2021
The aim of the present study was to compare the effects of assisted and resisted plyometric jump training on jump height, sprint performance (acceleration (0-20m), maximum speed (30-40m) and 40m sprint time) among physically active females. Fifty-six participants (age: 21.1 ± 1.7 years; body mass: 64.2 ± 7.0 kg; height: 168.0 ± 5.6 cm) were randomly allocated to either an assisted (n = 16) or resisted training group (n = 17), or a control group (n = 14). Nine participants dropped out during the intervention. The training sessions consisted of three different plyometric jump exercises over an eight-week period, while the control group continued their normal training routine. The results reve…
Practice and play in the development of German top-level professional football players.
2014
This study examined the developmental sporting activities of 52 German football first Bundesliga professionals (including 18 senior national team members) and 50 fourth to sixth league amateur players. They reported their volumes of organised football practice/training, including its "microstructure" (proportions of physical conditioning, skill exercises and playing forms), non-organised leisure football play and engagement in other sports through their career, respectively. Analyses revealed that the Bundesliga professionals performed moderate amounts of organised football practice/training throughout their career. They accumulated 4264 (mean value) hours over ~16 years before debuting in …
Effects of strength vs. endurance training and their combination on physical performance characteristics in female horseback riders
2020
BACKGROUND: The purpose of this study was to investigate effects of strength (S), endurance (E) and concurrent strength and endurance (SE) training on neuromuscular and cardiorespiratory characteristics during the 12-week volume-equated protocols in female horseback riders. METHODS: Subjects (N=44) (29.4±8.9 yrs) were assigned to S (n=11), E (n=11), SE (n=13) and control (C) (n=9) groups. Training consisted of progressive S, E or SE training 3x/week and riding exercise 4-6x/week. The measurements included maximal isometric bilateral leg press force (MVCLP) and EMG of VL and BF muscles, rapid isometric force production (0-500ms), maximal force of trunk extensor/flexors (MVCE/MVCF), countermo…
Different strategies for sports injury prevention in an America's Cup yachting crew.
2009
PURPOSE:: To analyze the effectiveness in reducing the number of sport injuries after application of different strategies of preventive physiotherapy during competition periods in an America's Cup yachting crew. METHODS:: A prospective physiotherapy intervention study during competition periods for three seasons was conducted on an America's Cup yachting race crew of 30 professional sailors. In the first two acts (2004), athletes did not receive any preventive physiotherapy. In the two acts celebrated in 2005, preventive intervention (phase 1) consisted of stretching exercises before the yacht race and preventative taping. During the four acts corresponding to the 2006 season, the physiothe…
Eye position tunes the contribution of allocentric and egocentric information to target localization in human goal-directed arm movements.
1997
Subjects were required to point to the distant vertex of the closed and the open configurations of the Muller-Lyer illusion using either their right hand (experiment 1) or their left hand (experiment 2). In both experiments the Muller-Lyer figures were horizontally presented either in the left or in the right hemispace and movements were executed using either foveal or peripheral vision of the target. According to the illusion effect, subjects undershot and overshot the vertex location of the closed and the open configuration, respectively. The illusion effect decreased when the target was fixated and when the stimulus was positioned in the right hemispace. These results confirm the hypothe…
Performance Analysis of Innovative Vacuum Insulation Panel
2013
Thermal insulation has become one of the central themes in energy behavior improvement. The use of insulating materials, from the thermal and hydrothermal aspect, allows the reduction of the heat transfer in each of the technical elements increasing their thermal inertia. Even if the research has led to the use of innovative materials with high values of thermal insulation, one of the main problems, which is difficult to resolve, is the thickness of the building envelope to reach levels of transmittance that can allow considerable savings of energy and CO2 emissions. With this objective the VIP (Vacuum Insulation Panel) technology in building applications is an innovative solution to obtain…
Effect of an exercise-based intervention on physical function of frail elderly patients with acute coronary syndrome
2021
Abstract Funding Acknowledgements Type of funding sources: Public grant(s) – National budget only. Main funding source(s): This work was supported by grants from CIBER CV, Madrid, Spain [grant number 16/11/00420] and Instituto de Salud Carlos III-FEDER, Madrid, Spain Background Frail elderly patients with cardiovascular diseases are vulnerable and more likely to experience physical function decline. Of the interventions that have shown some efficacy in the management of frailty, exercise is the only treatment found to consistently improve physical function. Since the number of older persons with cardiac diseases is gradually increasing, understanding how therapeutic exercise might be succes…
Physical function and frailty in elderly patients with acute coronary syndrome
2021
Abstract Funding Acknowledgements Type of funding sources: Public grant(s) – National budget only. Main funding source(s): This work was supported by grants from CIBER CV, Madrid, Spain [grant number 16/11/00420] and Instituto de Salud Carlos III-FEDER, Madrid, Spain. Background Frailty is described a complex clinical syndrome of increased vulnerability to stressors that places the individual at increased risk of adverse health outcomes. It results from multiple impairments (among others, in physical functioning) and its severity ranges from mild to severe. In older cardiac patients, frailty is reported to be a significant and an independent predictor of functional decline. Purpose To analy…
