LAB REPORT 1 RESULTS DATA ANALYSIS Average each HR per stage Graph HR vs. workload (WL) o See how to graph PowerPoint o Estimate max WL from graph o Calculate estimated VO2 with max workload by: VO2= 10.8 x Watts x (1/body weight) + 7 Figures: o Table of resting values/demographics for your subject (see table below) Results: o Table with stage, time, workload, HR, BP, RPE (see table below) o Extrapolation Graph & Estimated VO2max (use graph to find watts & plug in to the equation) o Include all calculations USE THIS DATA!! Demographics o Age: 20 o Gender: Male o Height: 183cm o Weight: 82kg o APMHR: 220-20 = 200bpm o BMI = 82kg/1.83m2 = 24.5kg/m2 Resting values o Resting HR: 70bpm o Resting BP: 100/78 mmHg Age Gender Stage 1 - 25W - HR1 = 94 - HR2 = 98 - BP = 100/80 - RPE = 8 Stage 2 - 75W - HR1 = 110 Height (cm) Weight (kg) BMI (kg/m2) APMHR (220-age) Resting Resting BP HR (bpm) (mmHg) - HR2 = 116 - BP = 120/90 - RPE = 11 Stage 3 - 100W - HR1 = 124 - HR2 = 128 - BP = 128/92 - RPE = 15 Stage 4 - 125W - HR1 = 134 - HR2 = 144 - HR3 = 148 - BP = 136/98 - RPE = 18 Stage Time Workload (watts) HR1 (bpm) HR2 (bpm) HR3 (bpm) BP (mmHg) RPE (6-20) Warm up 1 2 3 4 Calculations: APMHR: 220 – Age = APMHR (bpm) VO2= 10.8 x Watts x (1/body weight) + 7 LAB REPORT 1 DISCUSSION QUESTIONS 1. Did the HR and BP respond to work as expected? What are the physiological responses for these observations? Explain. 2. List and explain potential sources of error in predicting VO2max for the YMCA submaximal test. How could these sources of error be controlled? 3. Would you expect VO2max to be overestimated or underestimated in well-trained cyclists if you used the YMCA cycle protocol to test them? Give a rationale to support your answer.
