Individual Characteristics and Their Effect on Execution of a Standardized Partial Curl-Up Test
Bibliographic record
Abstract
BACKGROUND: According to the Standard Canadian Society of Exercise Physiology (SCSEP), individuals <45 yr are to complete the partial curl-up test at a reach distance of 12 cm. PURPOSE: This study aimed to investigate the effect of spinal flexibility, arm length, height, and torso length on execution of the SCSEP curl-up test, as factors not previously studied according to the knowledge of the researchers, and in addition to previously studied variables of age, waist circumference, plank time and reported physical activity. To the best of our knowledge, no study has assessed all of these variables at varying reach distances of 8, 10, and 12 cm. METHODS: Maximal plank time and anatomical assessments were recorded for 45 [age 22 (18-36)] subjects. Each subject completed a partial curl-up test following the SCSEP protocol as defined in the ACSM’s Guidelines for Exercise Testing and Prescription, Ninth Edition, at reach distances of 8, 10, and 12 cm in randomized order and 24-48 hours apart. A one-way MANOVA was calculated examining the effect of individual characteristics on performance of the three curl-up tests. RESULTS: A significant effect was found for age (Lambda (30, 94.6) = .252, p<.05) on execution of the curl-up test [Lambda (99, 27.8) = .001, p<.05]. Follow-up univariate ANOVAs indicated that execution of the curl-up test at 10cm and 12cm were significantly diminished ([F(10, 34) = 3.063, p < .05], [F(10,34) = 3.348, p<.05], respectively). Execution of the curl-up test was not significantly affected by spinal flexibility, arm length, torso length, waist circumference, maximal plank hold time, and reported physical activity. CONCLUSION: The decline in execution of the curl-up test with increasing age has been reported previously, however, it appears age may impact performance earlier than 45 yrs, warranting further research examining smaller age increments and their effect on curl-up execution. In subjects <45 yr, spinal flexibility, arm length, and torso length do not appear to impact execution of the curl-up test at any of the reach distances examined.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
