Altering Focus Of Attention Effects Isometric Muscular Endurance And Heart Rate During Fitness Testing
Abstract
Subtle instructional changes that direct attentional focus can lead to changes in performance, potentially hindering a fitness assessment. An external attentional focus has been found to improve motor performance, however less is known about instructional effects on performance and the physiological response during an isometric endurance test. To better understand how attentional focus effects endurance fitness tests, two experiments were conducted. Experiment 1 showed that an external focus instruction (68.41 sec, SD = 34.20) led to significantly higher endurance performance compared to an internal instruction (60.22 sec, SD = 34.54). Experiment 2 revealed that heart rate during the internal condition (M = 117.51 bpm, SD = 14.19) was higher compared to the external (M = 114.17 bmp, SD = 13.19) and control (M = 115.40 bpm, SD = 16.85). Additionally, performance was greater during external instructions (M = 107.01 sec, SD = 46.35) compared to internal (M = 95.25 sec, SD = 38.19).

In the citing paper
“Evidence from isometric tasks indicates that an external focus of attention can lower heart rate and improve performance (Markwell et al. 2021), whereas in running contexts, studies such as Ziv et al. (2012) report no significant differences in heart rate or running economy between external and internal focus.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
