“…The standing-up speed was externally controlled by audio signals via a metronome and visual signals using down and up arrows on the computer screen. The suspension criteria for the ISTS test were as follows: 1) when the general indications for stopping an exercise test, such as shortness of breath, wheezing, or leg cramps, in the ACSM's Guidelines for Exercise Testing and Prescription were met [1]; 2) when the heart rate (HR) reached 85 % of the predicted maximum HR [5]; and 3) when the timing given by the metronome was missed for three times in a row [14,20,22].…”

Incremental sit-to-stand exercise (ISTS) is an incremental exercise test using external signals to control the sit-to-stand rate in a given time frame. This study aimed to investigate the concurrent validity and reproducibility of the ISTS in aerobic fitness evaluation among healthy elderly women. Sixteen elderly women performed the ISTS and cycle ergometer test at 3-day to 2-week intervals, and six of the participants performed the ISTS twice. Peak oxygen uptake (VO), peak heart rate and completion time on the ISTS and cycle ergometer test were determined. Measured peak VO on the cycle ergometer test was significantly related to the peak VO (r=0.80, P<0.05) and the completion time (r=0.65, P<0.05) on the ISTS. The intraclass correlation coefficients were 0.96 for peak VO values and 0.91 for the completion time values during the two ISTSs. In conclusion, the ISTS is a valid, reproducible and safe test for aerobic fitness evaluation in healthy elderly women.

“…ercise load intensity can be easily adjusted by changing the STS speed or the seat's height [14,20]. With its simplicity, an STS exercise has been widely developed to evaluate knee extensor muscle strength for older adults in the clinical setting or for research purposes [13].…”

[Purpose] The aim of this study was to investigate the steady state of oxygen uptake (VO2) at several standing up frequencies to clarify whether workload in the sit-to-stand exercise (STSE) is greater than the anaerobic threshold (AT). [Subjects] Ten healthy young subjects performed the STSE. [Methods] In the STSE, subjects stood up and sat down without using their arms to push-off from the chair at standing up frequencies of 6, 12, 18, 24, 30, and 36 times per minutes. Subjects exercised for 5 minutes at each frequency with 5 minutes of rest between each consecutive frequency trial. The steady state of VO2 was evaluated by the difference in the VO2 between the 3rd and 5th min at each frequency. The correlation between the VO2 of the STSE and the standing up frequency was analyzed. [Results] At standing up frequencies greater than 24 times/min, the steady state of VO2 could not be confirmed. The relationship between the standing up frequency (at less than 24 times/min) and VO2 was strong (r=0.94). [Conclusion] The STSE may be a potentially useful test for determining AT and predicting the physical capacity of patients.

Background and objectives: The purpose of this study was to compare the energy expenditures (EE) of a single sit-to-stand (STS) movements with slow and normal speeds using a multi-stage exercise test. Materials and Methods: Twelve young males, aged 21–27 years (age, 23.0 ± 1.7 years; height, 171.2 ± 6.1 cm; weight, 64.3 ± 5.6 kg), performed repeated 3-s stand-up and 3-s sit-down (slow) or 1-s stand-up and 1-s sit-down (normal) movement on two different days with random order. All the participants completed multi-stage tests at different STS frequencies per minute. The slope and intercept of the linear regression relationship between the EE (kcal/min) and the STS frequency were obtained, and the slope of the regression was quantified as the EE of an STS. Results: The metabolic equivalents (METs) of the STS-slow was 4.5 METs for the frequency of 10 times/min (in total 1 min), and the net EE was 5.00 ± 1.2 kcal/min. The net EE of the STS-slow was 0.37 ± 0.12 kcal, which was significantly greater than that during the STS-normal (0.26 ± 0.06 kcal). The difference between the EEs of the STS-slow and STS-normal was significantly greater in taller and heavier subjects. Conclusions: We concluded that the intensity of STS-slow movement is moderate, and the EE during an STS-slow (0.37 ± 0.12 kcal) is higher than that during an STS-normal (0.26 ± 0.06 kcal). Our study results will help exercise and/or health professionals prescribe physical activity programs using STS movement for healthy young population groups.
