BIOL251 TEST QUESTIONS WITH CORRECT ANSWERS
2026 RATED A+
1. Describe the benefits of exercise -ANSWER- Increase life expectancy, increase aerobic fitness,
delay osteo
porosis, increase strength, decrease morbidity (heart disease, diabetes, high blood pressure),
increase brain blood
flow, increase psychological well being, maintain a healthy weight.
2. What are the ACSM guidelines for cardiorespiratory exercise? -ANSWER- At least 150 minutes
of moderate intensity per week, could be 30-60 minutes a day for 5 days or 20-60 minutes of
high intensity for 3 days.
Exercise can be done in either one continuous session or several shorter sessions (of at least 10
minutes). Gradual
progressions of exercise time, intensity and frequency is recommended for adherence and
reducing injury risk.
3. What are the ACSM guidelines for resistance exercise? -ANSWER- Train major muscle groups
2-3
days per week, waiting 48 hours between sessions. Training should consist of 2-4 sets of 8-12
reps of each exercise.
4. What are the ACSM guidelines for flexibility exercise? -ANSWER- Perform flexibility exercises
2-3
days per week. Do 2-4 sets of each stretch, holding each stretch to the point of discomfort for
10-30 seconds for a total
of 60 seconds for each stretch.
5. What are the ACSM guidelines for neuromotor exercise? -ANSWER- Perform exercises that
involve
motor skills (e.g balance, agility and coordination) such as yoga and tai chi for 20-30 mins 2-3
days per week. These
exercises improve physical function and prevent falls in older people.
6. Which health risks is sedentary behaviour associated with? -ANSWER- Adiposity, insulin resis
, tance, inflammation and possibly the progression of some cancers.
7. What are the acute responses to exercise? -ANSWER- Responses to exercise are controlled by
the nervous
and endocrine systems. Oxygen consumption and demand increases, glucose and fats are
mobilised for metabolism,
heart rate, body temperature, blood flow, breath frequency VE, VO2, VCO2 and blood lactate all
increase.
8. What body systems are impacted by exercise? -ANSWER- Respiratory, cardiovascular and
muscular
systems are all affected by exercise, they aim to increase oxygen and blood transport and
remove waste in order to
maintain homeostasis (balance) during exercise.
9. What are the three types of muscle? -ANSWER- Skeletal, cardiac and smooth.
10. What are the functions of muscles? -ANSWER- Locomotion, posture, assist with venous
blood return,
thermogenesis, energy transduction and protection of internal organs.
11. What are the properties of skeletal muscles? -ANSWER- Irritability (receive and respond to
signals),
Contractibility,(able to shorten, which requires ATP) Extensibility (able to stretch, doesn't
require energy) and Elasticity
(able to revert to resting length after stretching).
12. What is a neuromuscular junction? What is it's function? -ANSWER- Where a motor neuron
and muscle fibres meet (without touching). Impulses travel down the neuron and when the
neuromotor junction is
encountered the neurotransmitter is released across the gap which allows contraction of the
muscle.
