This study aimed to systematically review the association between telomere length (TL)
and muscular fitness. In October 2020, an articles search was applied to PubMed,
Scopus, and Web of Science. Eligibility criteria included: cross-sectional, prospective,
and experimental study design; outcomes included TL; results expressed the relationship
between muscular fitness and TL; studies published in English, Portuguese, or Spanish.
Nine studies were included in the review. Results from the four prospective studies are
mixed. In one study, the changes in TL were associated with grip strength. Another
study concluded that longer mid-life TL was associated with increased grip strength later
in life. However, in the other two studies, the association between TL and sarcopenia
was not strong. Nevertheless, longer TL was associated with a slower decline in grip
strength in older people. From the four cross-sectional studies, three indicated that TL
was associated with muscular fitness. On the other hand, in a study with powerlifters, TL
remained within the range of values found in subjects with no history of regular strength
training, supporting the notion that muscular fitness was not associated with TL. The
cross-sectional and prospective studies showed that the relationship between TL and
muscular fitness is not conclusive. It seems that there is a positive association between TL
and muscular fitness in middle-aged and older adults. However, among younger adults,
this relationship was not observed.
