Designed to strengthen the deep (stabilizer) muscles which stabilize joints and ligaments, core stability exercises are important for the development of motor skills in athletes. In this research, we aimed to determine how a two-year program of core stability and functional exercises influenced the strength and speed of female football players. The tested athletes (n = 17) were members of Olimpia Szczecin MKS, a first division football club from Poland. Their mean age was 19.8 ±1.4 years, while the mean duration of sport experience was 6 years. We analyzed their running speed, as well as the maximal strength of eight major muscle groups: rectus abdominals, abdominal oblique, shoulder girdle, chest, upper limbs, quadriceps, biceps and gastronomies. The effects of training on motor speed and strength were measured twice, prior to each of the two seasons. The functional training resulted in significant changes in the strength of various muscle groups: quadriceps (Δ17.1 kg; p < 0.05), abdominal oblique muscle (Δ9.1 kg; p < 0.05), shoulder girdle (Δ3.6 kg; p < 0.05) and chest (Δ3.5 kg; p < 0.05). There was also a significant reduction in the time of the 30 meter sprint (p < 0.05) (Δ0.1 s; p < 0.05). In summary, functional training had a positive effect on the strength and running speed of the tested female footballers.

The aim of this study is to review the available literature for factors affecting a basketball throw and the stabilization of the trunk. Searching for the most important elements which ought to be improved during training to increase the effectiveness of a throw and those which condition the correct stabilization of the trunk. The obtained results, after analyzing the literature, show that it is not possible to determine a single factor affecting a throw and the stabilization of the trunk. There are many factors that influence each other and, therefore, must be trained as one. There are biomechanical relationships between the effectiveness of making a throw, the positioning of the limbs, the trunk and the trajectory of the ball. It is important to mention the role of a factor outside biomechanics, such as the player’s psyche. Muscles have the greatest impact on stabilization. Muscle function would not be possible without proper control by the nervous system The conclusion section shows a large number of interacting factors responsible for the quality and effectiveness of the throw as well as for the stabilization of the trunk. This allows better planning and conducting of basketball training aimed at improving technique and throw effectiveness.

Background: Low back pain is a common problem in ballroom dancers. In the United States of America about 23% of all injuries in dancers is low back pain. Low back pain in dancers can be related to the extended position of the spine during dancing. The activity of the abdominal muscles, such as transverse abdominis and multifidus muscles can play significant role in the pathomechanics of the problem. These muscles are important for stability of the pelvis and the lumbar spine. The purpose of the study was to estimate the effectiveness of stability exercises of the lumbo-pelvic-hip complex in reducing low back pain among ballroom dancers. Material/Methods: 30 professional dancers (mean age of 19 years) both males and females participated in the research. Subjects were randomised into two groups. Dancers from the first group continued normal dance training with extra stability training (the experimental group). Participants from the second group continued normal dance training only, without any modifications (the control group). The pain rate was measured by the Numerical Pain Rating Scale. The stability muscles activity was estimated with the biofeedback pressure unit in supine and prone position. Results: After 6 weeks of stability trainings in dancers from experimental group low back pain significantly decreased and the stability muscles activity improved (p < 0.05). Conclusions: Results of the study show that stability exercises can be effective in reducing low back pain in ballroom dancers. However, prolonged observations and research comparing different training regimens (e.g. general exercises or Pilates) are needed.

No study has compared sling exercise training with elastic band resistance training in healthy older adults. Therefore, the purpose of this study was to determine whether different effects on functional mobility, strength and balance ability were produced by using different devices (sling trainer and elastic bands). Twenty-four participants were assigned to two different training groups, INT (TRX-OldAge) and CON (elastic bands). Participants trained three times per week for 30 minutes for 12 weeks. The Multisurface Obstacle Test for Older Adults (MSOT) and the 1-repetition maximum test using the chest press and the leg press were performed to assess functional mobility and dynamic strength, respectively. To examine balance ability, data of body-worn sensors and a force plate measured during different standing positions have been investigated. A main time effect occurred for functional mobility (p = 0.009) with a significant improvement within INT (p = 0.044), and for the chest press (p = 0.017) with a significant improvement within INT (p = 0.019). However, there was no group-by-time interaction in any of the measured parameters. Compared to elastic band resistance training, TRX-OldAge induced similar effects on the functional mobility, strength and balance ability of healthy older adults.

Background: Chronic low back pain (LBP) is the most common cause of disability, hence multiple attempts have been undertaken to develop therapeutic strategies aimed at addressing the issue. The most commonly used strategies include motor control exercises of deep core muscles that stabilize the lower back. However, on the practical side, they require application of special devices, such as ultrasonography or electromyography as well as instructions and support provided by trained personnel. Despite the lack of high-quality empirical evidence, these exercises are extensively used in clinical practice. Narrative Review: The vast body of literature collected suggests that the cause of chronic LBP should be sought in the structural and functional alterations within different levels of the central nervous system. These alterations and maladaptations apply to both the molecular and tissue levels. Nevertheless, successful treatment of these changes is currently possible due to an affordable, cognitive therapeutic approach. It encompasses a number of strategies that aim to restore the normal function of the nervous system using brain plasticity processes. These include graded motor imagery, mirror therapy, graded exposure, pain education, sensory training and pain coping strategies. Conclusions: Lack of clear advantage in the application of the core stability exercises over other, potentially cheaper alternatives, implies a shift-paradigm from the existing biomedical model of chronic LBP treatment towards modern cognitive approaches. As results of numerous studies confirm the validity of the approach aimed at restoring the structure and function of the central nervous system in contrast to the still common concept of treatment of the peripheral tissues of the body, more rigorous systematic reviews and meta-analysis are required. Evidence from this kind of evaluation may contribute to the shift in current beliefs regarding the treatment of chronic LBP.
