This lesson teaches a provider-set cycle-ergometer bout: set the bike consistently, warm up gradually, settle into a target power and cadence, check breathing, symptoms and perceived effort at fixed times, finish without a sprint and cool down. The provider controls clearance, mode, duration, intensity, recovery and whether oxygen-uptake testing is justified. Target outcome: The learner completes one supervised constant-power cycle bout inside the prescribed power/cadence band, with time, symptoms, effort and any oxygen-uptake data interpreted separately. ### Authority and setup conditions - Tell the provider about chest symptoms, fainting, unusual breathlessness, infection, medication changes and current joint pain. - Record the cycle model, seat/handle position, target power, cadence band and planned duration. - Check that emergency stop, foot retention and communication signals can be used without delay. - Rebuild saddle, handlebar and pedal settings from the fit sheet and pedal easily for a brief check. Continue only if cadence is smooth, the learner is not rocking and no concerning symptom appears. - Increase cycle work in planned stages until the target cadence and fit are stable; familiarisation minutes are not added to the measured bout. ### Required or supplied materials - Calibrated cycle ergometer with recorded seat and handlebar settings - Cadence and power display - Provider-approved heart-rate or gas-analysis equipment when relevant - Perceived-exertion and symptom scale - A cycle-endurance log for ergometer model and fit, power, cadence, duration, heart rate when authorised, effort, symptoms, interruptions, cool-down and recovery. ## 1. Rebuild the same bike fit Set seat and handlebars to the recorded positions, secure feet as authorised and pedal easily to confirm no reaching or joint pain. Why: Fit changes efficiency and which tissues limit the bout. Success check: Settings match the sheet and the learner pedals without rocking. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “Settings match the sheet and the learner pedals without rocking.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 2. Warm up in stages Begin at the provider's easy power and raise workload only at the stated times while keeping cadence inside the band. Why: A staged warm-up reveals problems before the work interval. Success check: Power and cadence rise without symptoms or abrupt breathing change. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “Power and cadence rise without symptoms or abrupt breathing change.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 3. Settle into target power At the work cue, adjust resistance and cadence until power stays within the target band; do not surge above it to build a buffer. Why: Early surges distort sustainable-performance measurement; this preserves the aerobic endurance rule for 'Settle into target power'. Success check: Power remains in band for the first two minutes. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “Power remains in band for the first two minutes.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 4. Hold a repeatable rhythm Keep cadence in its band, shoulders relaxed and hands light. Make small resistance or cadence corrections rather than repeated large changes. Why: Large oscillations waste effort and change the task. Success check: Minute averages stay within the declared tolerance. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “Minute averages stay within the declared tolerance.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 5. Report at fixed checkpoints At the scheduled minutes, state perceived effort, breathing comfort and any pain while continuing the same workload. Why: Symptoms and effort show how the same output is being tolerated. Success check: Every checkpoint has a complete response without missed warning signs. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “Every checkpoint has a complete response without missed warning signs.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 6. Finish without a sprint At the work endpoint, reduce resistance; do not accelerate for a final number unless the protocol specifically requires it. Why: A finishing sprint changes a constant-power test. Success check: The final work minute remains inside the same target band. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “The final work minute remains inside the same target band.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 7. Cool down and interpret Pedal easily for the provider-set time, then dismount only when stable. Record completed time/distance or power and keep VO2, heart rate and symptoms as separate measures. Why: Physiological and performance outcomes are related but not interchangeable. Success check: The log shows mode-specific output, effort, symptoms and recovery. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “The log shows mode-specific output, effort, symptoms and recovery.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## Reflection What changed? ________________________________________________________________________________ What remains difficult? ________________________________________________________________________________ What will I repeat, adapt, ask for help with, or stop? ________________________________________________________________________________ --- Completion of this worksheet demonstrates tutorial participation only.
