Abstract
OBJECTIVE To clarify the effect of growth and advancing age on lymphatic capillarization in rat skeletal muscles, we examined the histological and biochemical changes of lymphatic capillaries in different fiber types of skeletal muscles across juvenile, young, and middle-aged generations. METHODS We collected the tibialis anterior (TA), extensor digitorum longus (EDL), and soleus (SOL) muscles. Immunohistochemical staining using LYVE-1 and CD31 markers was used for lymphatic and blood capillaries, respectively. Real-time PCR was used to analyze mRNA expression of lymphangiogenic factors. RESULTS The density of LYVE-1-positive lymphatic capillaries in the muscles peaked during the juvenile period and subsequently decreased with increasing age. In contrast to blood capillaries, fast-twitch dominant muscles (i.e., TA and EDL) exhibited an age-related decrease in lymphatic capillaries. Similar to blood capillaries, lymphatic capillaries were abundant in SOL, a slow-twitch dominant muscle, which showed less susceptibility to age-related lymphatic decline. The mRNA expression of lymphangiogenic factors was significantly upregulated in SOL and decreased in all muscles of middle-aged rats. CONCLUSIONS The age-related decrease of lymphatic capillaries in fast-twitch muscles might be associated with age-related muscle atrophy.

Abstract
With the rapid development of sports science and molecular biology technology, academia refers to molecules or microorganisms that mimic or enhance the beneficial effects of exercise on the body, called "exercise mimetics." This review aims to clarify the concept and development history of exercise mimetics, and to define the concept of exercise mimetics by summarizing its characteristics and functions. Candidate molecules and drug targets for exercise mimetics are summarized, and the relationship between exercise mimetics and exercise is explained, as well as the targeting system and function of exercise mimetics. The main targeting systems for exercise mimetics are the exercise system, circulatory system, endocrine system, endocrine system, and nervous system, while the immune system is potential targeting systems. Finally, future research directions for exercise mimetics are discussed.

Abstract
Many neuromuscular disorders can have a differential impact on a specific myofibre type, forming the central premise of this review. The many different skeletal muscles in mammals contain a spectrum of slow- to fast-twitch myofibres with varying levels of protein isoforms that determine their distinctive contractile, metabolic, and other properties. The variations in functional properties across the range of classic 'slow' to 'fast' myofibres are outlined, combined with exemplars of the predominantly slow-twitch soleus and fast-twitch extensor digitorum longus muscles, species comparisons, and techniques used to study these properties. Other intrinsic and extrinsic differences are discussed in the context of slow and fast myofibres. These include inherent susceptibility to damage, myonecrosis, and regeneration, plus extrinsic nerves, extracellular matrix, and vasculature, examined in the context of growth, ageing, metabolic syndrome, and sexual dimorphism. These many differences emphasise the importance of carefully considering the influence of myofibre-type composition on manifestation of various neuromuscular disorders across the lifespan for both sexes. Equally, understanding the different responses of slow and fast myofibres due to intrinsic and extrinsic factors can provide deep insight into the precise molecular mechanisms that initiate and exacerbate various neuromuscular disorders. This focus on the influence of different myofibre types is of fundamental importance to enhance translation for clinical management and therapies for many skeletal muscle disorders.

Abstract
Objectives: To investigate the effect of kinesio taping (KT) and manual lymphatic drainage (MLD) on pain severity, breast engorgement, and milk volume in postpartum women. Materials and Methods: In this prospective randomized-controlled trial, we recruited 67 postpartum women who had breast engorgement and randomly assigned them to the KT, MLD, and control group. In the KT group, taping plus breast care was performed, MLD plus breast care was performed in the MLD group, and in the control group, only routine breast care was given for 10 days. Pain, breast engorgement, body temperature, and milk volume were measured. Examinations were repeated on days 1, 4, and 10. Results: The MLD group had significant reductions in pain and breast engorgement at all postintervention days compared with the control and KT group (p < 0.05). Milk volume increased among three groups, but the change in the MLD group was higher than in the KT and control groups (p < 0.05). There was no significant difference in the milk volume among the KT and control groups at all postintervention days (p > 0.05). Conclusions: MLD relieved breast pain and firmness more and increased milk volume in postpartum women compared with the KT and control groups. MLD can be recommended to postnatal mothers to better manage breast engorgement.
