Over the last decade, acute increases in range of motion (ROM) in response to foam rolling (FR) have been frequently reported. Compared to stretching, FR-induced ROM increases were not typically accompanied by a performance (e.g., force, power, endurance) deficit. Consequently, the inclusion of FR in warm-up routines was frequently recommended, esp...
Maximal strength measured via maximal voluntary contraction (MVC) is known as a key factor in competitive sports as well as injury prevention and rehabilitation. MVC and hypertrophy are commonly trained for by performing resistance training programs. However, literature shows that long-lasting static stretching interventions can also produce signif...
Measuring maximal strength (MSt) is a very common performance diagnoses, especially in elite and competitive sports. The most popular procedure in test batteries is to test the one repetition maximum (1RM). Since testing maximum dynamic strength is very time consuming, it often suggested to use isometric testing conditions instead. This suggestion...
Speed-strength performance is important during human movements such as jumping, sprinting, and change of direction (COD) tasks, which are a substantial part of sports practice. Sex and age seem to influence performance output in young persons; however, only a few studies have focused on the influence of sex and age measured via standard protocols o...
A single bout of foam rolling (FR) can acutely increase joint range of motion (ROM) without detrimental effects on subsequent muscle performance. Similarly, long-term FR training can increase ROM, while muscle performance seems to be unaffected. Although the acute and long-term effects of FR on the treated muscle are understood, the impact of FR on...
Animal studies show that long-lasting stretching training can lead to significant hypertrophy and increases in maximal strength. Accordingly, previous human studies found significant improvements in maximal voluntary contraction (MVC), flexibility and muscle thickness (MTh) using constant angle long-lasting stretching. It was hypothesized that long...
Introduction: If the aim is to increase maximal strength (MSt) and muscle mass, resistance training (RT) is primarily used to achieve these outcomes. However, research indicates that long-duration stretching sessions of up to 2 h per day can also provide sufficient stimuli to induce muscle growth. In RT literature, sex-related differences in adapta...
To improve flexibility, stretching is most commonly used and in training interventions
duration-dependent effects are hypothesized. However, there are strong limitations in used stretching protocols in most studies, particularly regarding documentation of intensity and performed procedure. Thus, aim of this study was to compare different stretching...
There are many reasons for reduced physical activity leading to reduced maximal strength and sport-specific performance, such as jumping performance. These include pandemic lockdowns, serious injury, or prolonged sitting in daily work life. Consequently, such circumstances can contribute to increased morbidity and reduced physical performance. Ther...
Introduction
An increasing number of studies investigate the influence of training interventions on muscle thickness (MT) by using ultrasonography. Ultrasonography is stated as a reliable and valid tool to examine muscle morphology. Researches investigating the effects of a training intervention lasting a few weeks need a very precise measurement s...
Speed strength performances are substantially dependent on maximum strength. Due to its importance, various methods have been utilized to measure maximum strength (e.g., isometric or dynamic) with discussed differences regarding transferability to sport specific movements dependent on testing procedure. The aim of this study was to analyze whether...
Background. Strength and speed are two major factors that determine performance in basketball players especially sprinting, jumping and change of direction. This study examined relationships of maximal strength in the front squat and the deadlift with basketball specific sprint and jump performance tests that are commonly used in test batteries of...
Many sports injuries result in surgery and prolonged periods of immobilization, which may lead to significant atrophy accompanied by loss of maximal strength and range of motion and, therefore, a weak-leg/strong-leg ratio (as an imbalance index ) lower than 1. Consequently, there are common rehabilitation programs that aim to enhance maximal stren...
The so called “stretch-induced force deficit” is known from a large number of research. There are many theories trying to explain the stretch-induced force deficit and increases in the range of motion (ROM) which all offer a stretch training specific explanation. However, when performing a commonly used strength training session a reduced maximum s...
Unterschiede in den Korrelationsstärken zwischen isometrischen und dynamischen Kraftmessungen sowie Sprungleistungen bei Nachwuchsfußballern
Einleitung
Der Anstieg der Maximalkraft ist Ziel einer Vielzahl von Trainingsprogrammen in Prävention und Rehabilitation. Um Maximalkraft- und Muskeldickenzuwächse zu erzeugen, wird im Regelfall ein Krafttraining durchgeführt. Ergebnisse aus Tierstudien zeigen jedoch, dass auch langanhaltende Dehnungsspannungen zu signifikanten Muskelmasse- und Ma...
Rebuilding strength capacity is of crucial importance in rehabilitation since significant atrophy due to immobilization after injury and/or surgery can be assumed. To increase maximal strength (MSt) strength training is commonly used. Literature from animal studies shows that long-lasting static stretching (LStr) interventions can also produce sign...
Muscular hypertrophy depends on metabolic exhaustion as well as mechanical load on the muscle. Mechanical tension seems to be the crucial factor to stimulate protein synthesis. The present meta-analysis was conducted to determine whether stretching can generate adequate mechanical tension to induce muscle hypertrophy. We used PubMed, Web of Science...
Previous research points out high relevance of maximal strength measurement in the diagnostics of
different populations. However, there is inconsistency in procedures of maximum strength measurements.
Thus, it must be questioned whether the results from different studies are actually comparable. Due to
the aforementioned problems in standardization...
In basketball high intensity jumping and sprinting performance is of high importance. There seems to be a relationship between maximal strength (MSt) and jumping performance in general, but influence of MSt in the plantar flexors and jumping performance seems not to be investigated very well. Thus, the aim of this study was to investigate the influ...
Background: In animal studies long-term stretching interventions up to several hours per day have shown large increases in muscle mass as well as maximal strength. The aim of this study was to investigate the effects of a long-term stretching on maximal strength, muscle cross sectional area (MCSA) and range of motion (ROM) in humans.
Methods: 52 su...
Practical Question: Is high-load squat training beneficial in improving sprinting performance in junior elite-level soccer players? Clinical Bottom Line: There is Level 3 evidence to support the validity of high-load squat training as a measure to improve sprinting performance in junior male elite-level soccer players. All three studies included sh...

Project (1)
The objective of the project is to investigate the effects of mechanical tension induced to skeletal muscles via stretching stimuli on morphological and functional parameters. We started the research topic using a calf muscle stretching orthosis to induce daily stretching for 10-120 minutes for 6 weeks. After showing significant increases in maximum strength, muscle thickness, muscle cross-sectional area and flexibility in young and healthy participants, the transferability to the elderly as well the investigation of the underlying physiological parameters should investigated in further research.
