LIFESCI 23L Lecture Notes - Lecture 7: Heart Rate Monitor, Grip Strength, Lung Volumes
Lecture G: Human Physiology
LAB CONCEPTS/SKILLS
● Taking measurements on yourself to formulate hypotheses about various physiological parameters and
testing the
● First part: data collection and data entry
● Second part: data access
● Concepts: how different physiological states relate to physiological activities such as running, squatting,
exercise
○ Or how these relate to physical properties → height, weight BMI
○ Forming hypotheses and using T-test
● Skills: using probes to collect data, taking measurements on human subjects, entering data onto online
database, and how to research a topic related to human physiology
○ No lab coat needed, just proper lab attire
BACKGROUND INFORMATION
● HUMAN PHYSIOLOGY
○ Parameters explored in lab: heart rate, EKG, muscle strength (EMG), lung volume
LAB DETAILS
● Four different stations
○ Station A: Heart rate measurements → wireless heart rate monitor, pace of heart contraction
■ Probe: handheld wireless heart rate monitor
■ Experiments: vital signs, exercisice, squatting, coughing
○ Station B: EKG/EMG → electrical activity of muscle
■ Probe: EKG (electrocardiogram)
● EKG: measures electrical activity in heart, used to measure heart activity and
health
○ Measure different components of EKG and ask questions about (e.g.)
gender
■ PROBE: EMG (electromyogram)
● EMG: graphical recording of electrical activity in muscles
○ Analyze electrical activity in forearm muscles under various conditions
(e.g. using a barbell)
○ Station C: Hand dynamometer → force of muscle contraction
■ PROBE: grip strength measurer
● Measure and compare the grip strength of both hands; correlate limb muscle
strenght to multiple factors such as gender and handedness
● Measuring grip fatigue: how fast do i get tired when i…
○ Grip continuously?
○ Grip repetitively?
○ Station D: Spirometer → volume and rate of air
■ Probe: measures air capacity and flow of lungs
● Measre lung volumes
● Measure respitory response during
○ Breath holding
○ Rapid breathing
○ Exercise
● Analyze lung function
● 11 different measurement probes for 11 different protocols

Document Summary
Taking measurements on yourself to formulate hypotheses about various physiological parameters and testing the. First part: data collection and data entry. Concepts: how different physiological states relate to physiological activities such as running, squatting, exercise. Or how these relate to physical properties height, weight bmi. Skills: using probes to collect data, taking measurements on human subjects, entering data onto online database, and how to research a topic related to human physiology. No lab coat needed, just proper lab attire. Parameters explored in lab: heart rate, ekg, muscle strength (emg), lung volume. Station a: heart rate measurements wireless heart rate monitor, pace of heart contraction. Station b: ekg/emg electrical activity of muscle. Ekg: measures electrical activity in heart, used to measure heart activity and health. Measure different components of ekg and ask questions about (e. g. ) gender. Emg: graphical recording of electrical activity in muscles. Analyze electrical activity in forearm muscles under various conditions.
