Warm-Up and Handgrip Strength in Physically Inactive Chilean Older Females According to Baseline Nutritional Status

“…Among the strengths of the study, we could mention the randomization of the intervention conditions and the analysis of the effects of the warm-up conditions according to baseline nutritional status. Based on the results found in the present study, it can be indicated that the warm-up based on static flexibility led to a decrease in HGS in physically inactive older females, while three isometric tests, without warm-up, allow reaching HGS with high reliability, which is beneficial in the time spent in performing this test, as well as in its applicability in the clinical setting [ 20 ]. Future research could delve deeper into exercise characteristics such as volume and intensity that may positively affect HGS in various age and gender ranges.…”

“…While it is well known that excess intramuscular fat can affect HGS [ 37 ], the scientific literature results do not agree with the impact of warm-up on HGS in overweight females. In the study of Hernández-Martínez, Rauch-Gajardo, Cisterna, Ramírez-Campillo, Moran, Knechtle, Nikolaidis, and Álvarez [ 20 ] in overweight youth females, no statistically significant differences were observed between the warm-ups with static flexibility and muscle strength compared to the control condition (no warm-up). However, the findings in our study report a decrease in HGS in obese older females with SSC being a statistically significant difference ( p < 0.05), presenting a moderate ES ( d < 0.60) concerning the CC and a magnitude of change between 10.2% and 11%.…”

“…In addition, it has been found that warm-up with muscular endurance or flexibility improves HGS in physically active older people [ 19 ]. On the contrary, Hernández-Martínez, et al [ 20 ] detected that warm-up did not lead to improvements in HGS, observing a trend of decreased HGS by static flexibility warm-up; however, such study was conducted with a physically inactive, young female.…”

“…Based on the above background, it seems relevant to confirm or refute these results in other populations by exploring the limits of the theories and, ultimately, to help the progress of specific knowledge related to this subject [ 20 , 21 , 22 , 23 ]. Taking into account that the type of warm-up can influence HGS as previously described, the main aim of this study was to analyze the effect of different types of warm-ups (static stretching and muscle strength) on HGS in physically inactive older females, and secondarily, to compare HGS according to their baseline nutritional status.…”
