In Periodic Paralysis (PP), a rare inherited condition caused by mutation in skeletal muscle ion channels, the phenotype changes with age, transitioning from episodic attacks of weakness that give its name, to more degenerative permanent progressive and myopathy. This leads disability reduced quality life. Neither cause this transition, nor why it occurs around age 40 is known. However, also onset ‘normal’ age-related physiological decline when we consider (a) mass strength (b) physical function at world class level (c) mitochondrial dysfunction.

Finding cost-effective prevention treatment strategies for sarcopenia the growing ageing population therefore great public health interest. Although nutrition considered important factor aetiology sarcopenia, its potential and/or still being evaluated. Nutrition research utilises three main approaches to understand muscle-nutrition relationships, evaluating: single nutrients, whole foods diet effects - both alone or combined exercise. Applying these approaches, we summarise recent evidence from qualitative quantitative syntheses findings observational intervention studies healthy adults, those sarcopenia. We consider protein supplements, (fruits vegetables) Mediterranean as exemplars. There some beneficial supplementation ≥ 0·8 g/kg body weight/d on when exercise training sarcopenic adults.

In skeletal muscle, calcium is not only essential to stimulate and sustain their contractions but also for muscle embryogenesis, regeneration, energy production in mitochondria, fusion. Different ion channels contribute achieving the various functions of muscles. Muscle contraction initiated by releasing from sarcoplasmic reticulum through ryanodine receptor gated mechanically four dihydropyridine receptors T-tubules. The influx store-operated sustains stimulates regeneration. Mitochondrial uniporter allows entry into mitochondria oxidative phosphorylation. Aging alters expression activity these different channels, resulting a reduction force generation regeneration capacity.

Methods was conducted Prishtina region, Kosovo, community-dwelling adults over 40 years of age. Genomic DNA extracted from saliva samples assess single nucleotide polymorphisms receptor (VDR) gene (rs7975232, rs2228570, rs731236, also referred as ApaI, FokI, TaqI, respectively) binding protein (GC) (rs4588, rs2282679).

Sarcopenia refers to the rapid loss of skeletal muscle mass and strength, which can result in serious consequences such as falls, fractures, a higher risk mortality. The prevalence sarcopenia is observed be twice high individuals with type 2 diabetes mellitus. Notably, there bidirectional relationship between mellitus, where each condit‑‑ion exacerbate progression other. Overlapping pathophysiological mechanisms, insulin resistance, inflammation, oxidative stress, accumulation advanced glycation end products, mitochondrial dysfunction, myosteatosis, aging process itself contribute development both conditions. A few treatments, myostatin antagonists, testosterone supplementation, selective androgen receptor modulators have been explored, but many remain experimental or clinical trial stages. cornerstone management involves nutritional intervention foods rich protein, essential amino acids, vitamin D, omega-3 fatty acids. Additionally, incorporating regular physical activity, particularly resistance exercises, minimizing sedentary behavior are key components for sarcopenia.
