Objective: The objective of this study is to investigate if sustained and repetitive prone press-ups could reverse decreased spinal height following spinal loading and if there was a correlation between the degree of end range of motion spinal extension and spinal height gains. Design: Pretest-posttest crossover design is used in this study. Setting: Study was carried out in research laboratory. Subjects: Forty-one healthy men and women were included in this study. Intervention: Participants were seated in the stadiometer for 5 min with a 4.5-kg weight placed on each shoulder; the load was removed for 5 min and spinal height was measured using a stadiometer before and after 5 min of repetitive or sustained prone press-ups. Main Measures: Two-by-two repeated-measures ANOVA to identify significant interactions and main effects is used in this study. Significance of α = 0.05. A Pearson correlation coefficient was used to assess the correlation between spinal height changes and spinal extension ROM. Results: Participants 24.1 ± 2.03 years grew using both repetitive (4.85 ± 3.01 mm) and sustained press ups (4.46 ± 2.57 mm). There was no significant interaction between the repetitive versus sustained press-ups and the time before and after each prone press-ups strategy and no main effect for strategy (sustained vs. repetitive press-ups). There was a significant main effect for time (before vs. after press-ups) (F(1,30) = 140.771; p < 0.0001; partial η2 = 0.82). No correlation was found between the degree of end ROM spinal extension and spinal height changes following press-ups strategies. Conclusion: Following periods of spinal loading, both repetitive and sustained press-ups increased spinal height. Such strategies could be used to help recover spinal height and limit the effects of decreased spinal height as a result of activities of daily living.
