Decreased hormone levels like testosterone and growth hormone affect muscle fibre composition.
As people age, there are natural adaptations in muscle fibre types that highlight the importance of staying active and maintaining a healthy lifestyle. With advancing years, decreased hormone levels like testosterone and growth hormone cause a gradual shift towards slower-twitch (Type I) muscle fibres, which are well-suited for endurance activities and sustained movement.
While fast-twitch (Type II) muscle fibres may decrease in proportion, regular physical activity, particularly resistance training, can help preserve muscle mass and strength. Engaging in exercise routines that include both aerobic and strength-training components can significantly mitigate the effects of ageing on muscle fibre composition.
Moreover, by staying active, individuals can enhance neuromuscular coordination and motor unit activation, which are essential for maintaining balance and mobility as they grow older.
A balanced diet rich in protein, vitamins, and minerals complements an active lifestyle, supporting muscle health and overall vitality. Embracing these positive habits fosters a fulfilling and active life throughout the ageing process.
