In comparing the two types of cycling exercises, the perceptual responses, such as perceived exertion and fatigue, as well as subjective feelings of energy, are crucial metrics. Lower limb cycling is traditionally associated with higher levels of exertion due to the larger muscle groups involved. However, when EMS is applied, both upper and lower limb cycling might exhibit altered perceptions of effort and energy levels, with EMS potentially equalizing the exertional differences. This research is significant for designing exercise programs that optimize energy expenditure and enhance performance, particularly in rehabilitative settings or for individuals looking to diversify their physical training regimens.
Perceptual responses, such as perceived exertion and enjoyment, play a critical role in exercise adherence and overall experience. By examining the differences in these responses between upper and lower limb cycling combined with EMS, we can identify which modality might be more favorable for maintaining motivation and engagement in young adults. This demographic is particularly crucial as they transition into lifelong fitness habits. Exploring how EMS impacts these perceptual responses can provide insights into optimizing exercise regimens for enhanced user experiences, potentially leading to better adherence and improved fitness outcomes.

Upper Limb Cycling with EMS: Participants will perform cycling exercises using an arm ergometer combined with EMS applied to the upper limbs. (Biceps, triceps, and deltoids) Jones et al., 2011
Lower Limb Cycling with EMS: Participants will engage in traditional cycling exercises using a stationary bike with EMS applied to the lower limbs. (Quadriceps, hamstrings, and calf muscles)

Perceptual Responses
Assessed using the Rate of Perceived Exertion (RPE) scale.
Time frame: at baseline and at 8 weeks
Self-Perceived Energy Feeling
(All participants will fill a short questionnaire (from 1 to 5 points) about their perception of energy before every training. Energy Feeling will be assessed (Evergy level, Fatigue Level, Feeling of Alertness, and Feeling of Focus for the task, valued from 1 = low energy to 5 = high energy).
Time frame: at baseline and at 8 weeks
Perception of Effort during Endurance Training
(Borg Scale (6-20) will be used to collect the perception of effort during endurance training (every 5 minutes) and 15-20 minutes after each session).
Time frame: at baseline and at 8 weeks
Blood lactate concentration
measured using capillary puncture during submaximal and maximal incremental exercise
Time frame: at baseline and at 8 weeks
