• Students will sit and relax for 2 minutes. They will then take their pulses (heart rate) for
30 seconds, multiply by two, and record this as the "resting pulse" in beats per minute.
• The demonstrator will tap three times (E.g., with a pencil on the table) and immediately
the students will stand up and hop on one leg for 30 seconds. After the jump the students
will take their pulse rates again, double it and record it as "Hop #1."
• This procedure will be repeated four more times (to give a total of 5 experimental hops),
and data recorded each time. Remember to rest for 3 minutes between experiments.
• After the five replications the students will sit and relax for 10 minutes until the pulse
returns to the initial resting pulse rate.
• The demonstrator will then tap the signal and the students will take their pulses without
having to hop.
• Record and tabulate the data.
Results
Table 1. Results of the classical conditioning practical where the heart rates (beats per
minute) of 30 students were measured: Rest HR = resting rate, Reps 1-5 = the average
rates measured for each student during the five exercise (hop) repetitions, Rest = re-
established resting rates of the students after the exercise routine, Signal = heart rates
measured after the signal (three pencil taps without exercise (hopping).
Task:
Use the data supplied in Table 1 to do the tasks:
1. Calculate the average hart rates for:
Rest HR = resting rate,
Reps 1-5 = the average rates measured for each student during the five exercise
(hops) repetitions,
Rest = re-established resting rates of the students after the exercise routine,
Signal = heart rates measured after the signal (taps without hops).
2. Construct a suitable graph using the averages calculated in 1 above with the
following title:
