Clinical Pilates Vs Classic Pilates - What is the difference?

As many of you know our ProMOTION Pilates Classes are all taught by experienced Chartered Physiotherapists. This means that we can modify the Classic Pilates exercises depending on the specific needs of the individual attending the class. They may have an injury or health condition that may prevent them doing some of the exercises. A modified version of the exercise is then required. Equally they may have no injuries or health conditions and do not require any modifications.This modification of the Classic Pilates exercises is often referred to as "Clinical Pilates". Chartered Physiotherapists with additional Pilates Training are in a great position to teach Clinical Pilates as they have a wide, in depth knowledge of injury and musculoskeletal conditions.Claire, one of our experienced Physiotherapists and Pilates instructors has written a blog on this topic which you can read all about here:https://www.promotionphysiotherapy.co.uk/.../differences.../ #clinicalpilates #physioledpilates #pilatesedinburgh

"The locust jump is composed of three phases, cocking, co-contraction and triggering."

"In the cocking phase, the tibia are fully flexed and a locking mechanism is engaged to prevent the tibia from extending prematurely.

During the co-contraction phase, the tibia extensor muscle contracts simultaneously with the flexor muscle and power is stored in the extensor apodeme, cuticle deformation, and the semi-lunar process at the femoro-tibial joint.

During the triggering phase, inhibitory neurons reduce the tension in the flexor muscle to allow the locking mechanism to disengage and release the stored energy to extend the tibia and produce the jump."

"The jump direction is determined by the orientation of the prothoracic legs as they rotate the body to point towards the target prior to the jump. The elevation of the jump is determined by the posture of the metathoracic legs."

"Because the energy budget for a grasshopper jump is constrained by the energy that is stored in the elastic processes of the limb, energy used for rotation has to come at a cost to energy used to generate linear velocity."

🔬 High-Intensity Interval Training (HIIT) and Brain Health: Mechanisms and Benefits 🧠 --- A recently published review article titled "HIITing the brain with exercise: mechanisms, consequences and practical recommendations" in The Journal of Physiology explores the profound impact of High-Intensity Interval Training (HIIT) on brain health. This comprehensive review elucidates the underlying mechanisms and practical applications of HIIT, highlighting its potential cognitive benefits. --- Key Highlights: Neurovascular Function: HIIT significantly enhances neurovascular function by improving blood flow and nutrient delivery to the brain, which is crucial for maintaining cognitive function and overall brain health. --- Neuroprotective Factors: The training method increases the production of neuroprotective factors, such as Brain-Derived Neurotrophic Factor (BDNF). BDNF supports the growth, survival, and differentiation of neurons, playing a critical role in brain plasticity and cognitive function. --- Cognitive Benefits: Regular HIIT sessions are associated with improvements in memory, executive function, and processing speed. These cognitive enhancements are particularly beneficial for aging populations and individuals at risk of neurodegenerative diseases. --- Practical Recommendations: The review provides detailed guidelines for safely and effectively incorporating HIIT into fitness routines. It emphasizes the importance of tailoring programs to individual fitness levels and health conditions to maximize benefits and minimize risks. -- Future Research Directions: The article suggests various areas for future research to further explore the neurobiological mechanisms behind HIIT's cognitive benefits. It highlights the need to optimize training protocols for different populations to achieve the best outcomes. --- Importance of the Study: The findings underscore the potential of HIIT as a non-pharmacological intervention to enhance cognitive function and prevent cognitive decline. Incorporating HIIT into regular exercise routines can significantly contribute to brain health, making it an invaluable tool for both healthcare professionals and fitness enthusiasts. --- 1.

The Impact of Digital Devices on Myopia Progression in Adolescents: What You Need to Know

Introduction Myopia, or near-sightedness, is on the rise among teens worldwide, and with the widespread use of digital devices, researchers are digging into the possible connection between screen time and worsening vision in young people [1][2]. From smartphones and tablets to computers, these devices have become a daily part of teens' lives for school, socializing, and entertainment [3]. While we have known that close-up work can contribute to myopia, there is growing interest in understanding exactly how digital screens might impact adolescent eye health [4][5].

What the Research Says

A recent study looked at a wide range of research on screen time and myopia, and the findings were pretty revealing. Here is what they discovered about how different types of digital devices and screen time may be impacting young people’s eyesight:

Screen Time and Myopia Risk The more time adolescents spend on screens, the more likely they are to experience myopia progression. For example, every extra hour of daily screen time increased the risk of myopia worsening by 1.26 times [6]. This effect seems dose-dependent—the more time spent on screens, the greater the risk.

Device-Specific Effects Not all screens are created equal when it comes to eye health. The study found that handheld devices like smartphones and tablets are more strongly linked to myopia progression than desktops or TVs [7]. This might be because we tend to hold phones and tablets closer to our eyes, which could strain vision more over time.

Why Digital Devices May Worsen Myopia

Extended Close-Up Work: When we stare at screens up close for extended periods, it can cause what is called "accommodative stress," potentially leading to the eye growing longer, which makes distance vision blurrier [8].

Less Outdoor Time: Increased screen time often means less time spent outdoors. Studies have shown that outdoor light exposure can help protect against myopia.

Blue Light Exposure: Digital screens emit blue light, which may disrupt circadian rhythms and, some researchers think, may play a role in how our eyes develop.

What This Means for Teens and Parents

The link between screen time and myopia progression suggests that some easy changes could make a significant difference for adolescent eye health. Here are a few ways to help manage screen time for healthier vision:

Encourage Regular Breaks: Follow the 20-20-20 rule—every 20 minutes, look at something 20 feet away for at least 20 seconds.

Get Outdoors: Time spent outside has shown protective benefits against myopia, so encouraging outdoor activities can be a simple but effective way to support eye health.

Use Blue Light Filters: Many devices offer blue light filter settings. These can help reduce eye strain, especially when screen use is necessary in the evening.

Looking Forward Most of the current studies rely on self-reported screen time, which can be a bit subjective. Moving forward, researchers aim to use more objective measures, like screen time tracking apps, to get a clearer picture of screen time's true impact on myopia. Longer-term studies will also be helpful in exploring the lasting effects of digital device use on vision.

Conclusion In summary, the evidence points to a strong connection between digital device use and myopia progression in adolescents. Taking steps to manage screen time, encourage outdoor activities, and use blue light filters can help protect vision health. With eye care professionals and policymakers on board, we can better address these risks and work toward healthier digital habits for the next generation.

Rapid physiological integration of fused ctenophores: Current Biology

Here, we report that two injured Mnemiopsis leidyi individuals, a species of planktonic animals known as comb jellies or ctenophores, are capable of rapidly fusing into a single entity in which some physiological functions are integrated. Our results highlight two interesting phenomena. First, ctenophores may lack an allorecognition mechanism that prevents fusion events between conspecifics. Second, fused individuals rapidly integrate and share physiological functions and neurobehavioral outputs.

Geschlechtsabhängige Auswirkungen von CBD?- Neue Erkenntnisse aus einer Studie

Die Studie von Hopkins et al. (2023) untersuchte die Auswirkungen der oralen Einnahme von CBD-reichem Hanfextrakt auf Entzündungen bei weiblichen und männlichen Ratten. Interessanterweise wurde festgestellt, dass weibliche Ratten, nachdem sie dem Stresstest ausgesetzt waren, eine geringere Zunahme von Entzündungsproteinen zeigten als männliche Ratten. Dies legt nahe, dass die geschlechtsabhängigen Effekte von CBD weiter erforscht werden sollten.

Fazit

Die ForscherInnen schlussfolgerten, dass die Ergebnisse der Studie darauf hindeuten, dass die Effekte der oralen Einnahme von einem CBD-reichen Hanfextrakt geschlechtsabhängig sein könnte. Hier seien weitere Untersuchungen notwendig, da noch völlig unklar ist, ob sich die Ergebnisse auch auf Menschen übertragen lassen.
