Abstract

Neuromuscular properties decline with ageing and low-level physical activities. Alaska pollack protein (APP) is reportedly effective for improving skeletal muscular functions, even if the amount is small and exercise is not conducted. However, it is unclear whether APP intake without an exercise program affects neuromuscular dysfunction in community-dwelling adults conducting normal, everyday activities. This study aimed to investigate changes in motor unit firing properties by adding APP to daily meals in community-dwelling older adults. They were divided into an APP group or a placebo control (CON) group for randomised, double-blind treatment. Participants in APP (

Research summary

The paper investigates the effects of Alaska pollack protein on motor unit firing rates in older adults, which relates to neuromuscular decline associated with aging. While it addresses a specific aspect of aging, the study focuses on dietary intervention rather than tackling the root causes of aging or lifespan extension. The findings may contribute to understanding age-related muscular decline, but the overall impact on the field of longevity research is limited.
