Background
This study aims to calculate and compare aerobic and anaerobic energy expenditure in women participating in recreational mini-trampoline activities.
Methods
Thirteen women volunteered to participate in this study. Cardiorespiratory and metabolic variables—including \(\:\dot{V}{O}_{2}\) (L/min), \(\:\dot{V}{O}_{2\:}/kg\) (ml/min/kg), \(\:\dot{V}{O}_{2}/HR\) (ml/beat), HR (bpm), \(\:\dot{V}E/\dot{V}{O}_{2}\) , \(\:\dot{V}E/{\dot{V}CO}_{2}\) , RER, \(\:\dot{V}E\) (L/min), FAT (g/h), METs, and \(\:{\dot{V}CO}_{2}\) (L/min) were measured using a portable gas analyzer (Cortex Metamax 3B). The mini-trampoline protocol was structured to progressively increase exercise intensity over a 5-minute period (2 and a half min aerobic rhytym; 2 and a half min anaerobic rhytym intensity), with load progression achieved through gradual increases in jump amplitude and movement frequency. The exercise protocol was performed to an instrumental music track characterized by a constant tempo of 128 bpm, a regular 4/4 meter, distinct metrical accents, and no lyrics. Although the tempo was kept constant, rhythmic variations were utilized to distinguish between the aerobic and anaerobic phases. Data were analyzed using a paired-samples t-test to compare the phases, with statistical significance set at p < .05.
Result
As a result of the research, there were significant differencies found between Phase 1 (aerobic) and Phase 2 (anaerobic) according to \(\:\dot{V}{O}_{2}\) (L/min), \(\:\dot{V}{O}_{2\:}/kg\) (ml/min/kg), \(\:\dot{V}{O}_{2}/HR\) (ml/beat), HR (bpm), \(\:\dot{V}E/\dot{V}{O}_{2}\) , \(\:\dot{V}E/{\dot{V}CO}_{2}\) , RER, \(\:\dot{V}E\) (L/min), FAT (g/h), METS, \(\:{\dot{V}CO}_{2}\) (L/min) variables (p < .001).
Conclusion
Mini-trampoline exercise emerges as a robust and time-efficient training method capable of eliciting significant aerobic and anaerobic responses, alongside high energy expenditure.
