Why test muscle tone?5 answersAssessing muscle tone is important for the diagnosis, prognosis, and treatment planning of developmental disabilities (DD) in children. It can also help in evaluating the effectiveness of therapeutic interventions in persons with spasticity and other upper motor neuron disorders. Muscle tone is a commonly used but often poorly defined concept in studies of movement and posture. Objective measurement of muscle tone is needed as current assessments, such as the Ashworth Scale, are subjective and unreliable. Muscle tone is an expression of tissue stiffness and can change due to disease, such as hypotonia or hypertonia. The ability to objectively quantify muscle tone can provide valuable information in the research of spasticity and can help in detecting abnormal tone that affects motion performance. Therefore, testing muscle tone is essential for clinical practice and research purposes.
To test muscle flexibility using active or passive length test?3 answersMuscle flexibility can be tested using both active and passive length tests. Passive stretching techniques, such as static stretching and muscle energy technique (MET), have been shown to improve muscle flexibility. These techniques involve applying an external force to lengthen the muscle without active muscle contraction. On the other hand, active stretching tests, such as the active knee extension test, involve actively contracting the muscle while lengthening it. The choice of test may depend on the specific goals and preferences of the individual or the context in which the test is being conducted. Passive length tests may be more suitable for assessing acute changes in muscle flexibility, while active length tests may provide a more functional assessment of muscle length in relation to specific activities or sports.

Does the range of motion in training the quadriceps matter for tendon adaptations ?
5 answers
The range of motion (ROM) in training the quadriceps does matter for tendon adaptations. Research indicates that manipulating joint ROM during squat training can have differential effects on strength training adaptations. Studies comparing deep squats (DS) with shallow squats (SS) show that DS training results in superior increases in front thigh muscle cross-sectional area (CSA), isometric knee extension strength, and squat-jump performance. Additionally, a systematic review and meta-analysis suggest that full ROM resistance training is more effective than partial ROM in maximizing muscle strength and lower-limb muscle hypertrophy. Furthermore, performing large ROM isoinertial exercises at faster movement speeds can provide an additional mechanical stimulus for tendon adaptation. Therefore, the ROM used in quadriceps training can significantly impact tendon adaptations, highlighting the importance of considering ROM in training protocols for optimal outcomes.

5 answers
Lysophosphatidylcholines (LPCs) play a significant role in obesity-related metabolic changes. Studies show that obesity is linked to alterations in the lipidomic profile, with LPCs being highlighted as potential biomarkers of obesity. In individuals with obesity, there is an increase in lysophospholipids (lyso-PLs) and lysophosphatidylcholine acyltransferase 3 (LPCAT3) expression, impacting skeletal muscle insulin sensitivity. Furthermore, a strong correlation exists between lysophosphatidylcholine levels and muscle contractile force, with LPCAT3 influencing muscle strength and myopathy development in obesity. Additionally, specific LPC species like LPC (17:0) have been found to reduce blood glucose, alleviate insulin resistance, and activate G protein-coupled receptors, suggesting a protective role against hyperglycemia and insulin resistance in obesity-related conditions.
How do Lysophosphatidylethanolamines affect obesity?
5 answers
Lysophosphatidylethanolamines (LPEs) play a significant role in obesity-related metabolic disturbances. Studies have shown that alterations in LPE levels are associated with the progression of nonalcoholic fatty liver disease (NAFLD) in obese individuals, leading to increased susceptibility to disease development. In skeletal muscle, obesity accelerates the skeletal muscle Lands cycle, impacting muscle insulin sensitivity through changes in LPE abundance. Additionally, genetic obesity alters the liver phosphatidylcholine/phosphatidylethanolamine ratio, inducing endoplasmic reticulum stress without a concomitant increase in ER chaperones, highlighting the role of LPEs in obesity-related liver dysfunction. These findings collectively emphasize the intricate involvement of LPEs in the pathophysiology of obesity and associated metabolic disorders.
Is the measured tissue concnetration using Microdialysisi or open flow microperfusion dependent on the tissue depth?
5 answers
The measured tissue concentration using Microdialysis or open-flow microperfusion (OFM) can be influenced by the tissue depth. Microdialysis, a technique that studies the biochemistry of tissues, involves inserting a microdialysis catheter into subcutaneous tissues, muscles, or viscera, depending on the type of flap, to sample interstitial fluid. On the other hand, OFM, which utilizes a steel mesh with macroscopic openings, allows unfiltered sampling of interstitial fluid for quantification in the target tissue. The depth at which these techniques are applied can impact the recovery of substances like lipids. Therefore, the tissue depth at which Microdialysis or OFM is performed plays a role in determining the accuracy and reliability of the measured tissue concentrations.

Additionally, a bilateral limb synchronous exercising device has been designed to improve user comfort and achieve exercise training with opposite directions for bilateral lower and upper limbs. Furthermore, a meta-analysis comparing unilateral and bilateral exercises suggests that unilateral training is more effective in enhancing jumping ability, sprinting ability, and maximum strength, while bilateral training is more beneficial for balance and strength quality in bilateral power patterns. Moreover, in stroke patients, bilateral activity with a pilates ring has been found to be more effective in facilitating muscle activation and coordination compared to bilateral activity with hands clasped.
What is the trajectory of muscle oxygenation levels after a single bout of resistance training?
5 answers
After a single bout of resistance training, muscle oxygenation levels exhibit specific trajectories. Studies have shown that resistance exercise induces oxidative damage despite an increase in antioxidant capacity in blood and skeletal muscle. Additionally, maximal concentric contraction exercise does not lead to prolonged changes in muscle oxygenation, with observed changes potentially reflecting excess post-exercise oxygen consumption. Furthermore, the ingestion of carbohydrates or carbohydrates associated with proteins and antioxidants during resistance exercise can decrease muscle damage without affecting lipid peroxidation markers. These findings collectively suggest that muscle oxygenation levels may initially decrease post-exercise but recover within a short period, indicating a dynamic response to resistance training.
How long after a single bout of resistance training is muscle oxygenation decreased?
4 answers
Muscle oxygenation decreases immediately after a single bout of resistance training. This decrease in muscle oxygenation is influenced by the type of training protocol used. For instance, in the 3/7 protocol, muscle oxygenation did not return to resting values between sets, indicating a continuous decrease. Additionally, the rate of decrease in muscle oxygenation was significantly higher in power lifters compared to ordinary healthy individuals, especially at higher intensities of maximal lifting weight, and the recovery time for muscle oxygenation to reach 50% of its original level was delayed in the power lifters group. These findings suggest that muscle oxygenation levels are promptly affected by resistance training and can vary based on the training method and individual muscle fiber composition.
How long after a single bout of resistance training is blood lactate elevated?
4 answers
Blood lactate levels remain elevated after a single bout of resistance training for a significant period. Research indicates that post-exercise blood lactate concentrations were notably higher, reaching levels of around 7.0 mmol/L, compared to pre-exercise levels. This elevation in blood lactate was observed immediately after exercise and persisted for a considerable duration. Additionally, the study highlighted that blood lactate concentrations were still elevated at 5 minutes post-exercise, indicating a sustained effect on lactate levels. The data suggests that blood lactate remains elevated in the post-exercise period, reflecting the metabolic demands and physiological responses associated with resistance training.
Which is best for muscle recovery whey or casein?
5 answers
Whey protein appears to be more beneficial for muscle recovery compared to casein. Research suggests that whey protein promotes faster recovery of muscle functional properties after a period of immobilization, leading to quicker restoration of isometric force and concentric power output relevant for natural locomotion. Whey protein is highlighted for its high-quality protein content, supporting skeletal muscle maintenance during aging and aiding in anabolic support during periods of illness or injury. On the other hand, casein is a standard protein source but may not offer the same rapid recovery benefits as whey protein. While both proteins have their merits, whey protein's ability to enhance muscle recovery and functional abilities makes it a preferred choice for individuals looking to optimize muscle recovery processes.
How do different types of training affect substrate utilization patterns in individuals?
9 answers
Different types of training and dietary interventions significantly affect substrate utilization patterns in individuals, influencing how the body uses fats and carbohydrates during exercise. High-intensity and endurance training, as well as dietary modifications, play pivotal roles in determining the predominant fuel source during physical activity. High-intensity exercise tends to shift substrate utilization towards carbohydrates as the primary energy source. A study found that during maximal efforts, athletes exhibited a later crossover to carbohydrates from fats, indicating a higher reliance on lipids at the onset of high-intensity exercise. This shift was influenced by body composition, with individuals having a higher percent body fat (PBF) showing increased lipid oxidation during intense activities. Conversely, endurance training, especially when coupled with a very low carbohydrate ketogenic diet (KD), has been shown to increase fat oxidation rates and decrease carbohydrate utilization even at moderate-to-high exercise intensities, leading to changes in body composition and substrate utilization patterns. The impact of exercise-induced muscle damage (EIMD) on substrate utilization also reveals a preference for carbohydrate oxidation during recovery from damage, suggesting an increased reliance on muscle glycogen. Similarly, intensified training periods without dietary intervention have been observed to enhance fat oxidation and efficiency while decreasing carbohydrate oxidation, indicating an adaptation towards more efficient fuel use over time. Dietary interventions, such as low-carbohydrate meals, have been shown to result in greater lipid oxidation at rest and during exercise compared to low-fat meals, highlighting the influence of diet on substrate utilization. Moreover, multiday strenuous exercise increases protein catabolism and fat oxidation, further altering substrate utilization patterns. Endurance training and gender differences also affect substrate utilization, with endurance-trained individuals showing specific patterns of substrate use during prolonged exercise. Strategies aimed at reducing skeletal muscle dependence on carbohydrate fuel sources, such as high-fat diets or ketone supplementation, have been explored but show mixed results regarding their effectiveness and impact on performance and substrate metabolism. Lastly, substrate utilization during exercise in trained prepubertal boys compared to adults indicates a higher lipid oxidation in boys at lower exercise intensities, suggesting age and development stage also influence substrate utilization patterns. In summary, substrate utilization patterns are influenced by a complex interplay of exercise intensity, type of training, dietary interventions, body composition, and individual physiological factors, including age and gender.
