Exercise Physiology Flashcards

‥ Decrease BP ‥ Increase HR

Answer: Diuretics

Diuretics are medications that increase the excretion of water and sodium, primarily used to lower blood pressure (decrease BP) by reducing fluid volume. While they decrease BP, some diuretics can cause a compensatory increase in heart rate (increase HR) as the body attempts to maintain cardiac output. This matches the described physiological effects.

To see results, resistance training needs to be done frequently (a few times each week). 2-3 times weekly.

Answer: Frequency

The principle of frequency in exercise training refers to how often workouts are performed. For resistance training, performing sessions 2-3 times per week is a standard recommendation to achieve results and allow for adequate muscle recovery and adaptation. This aligns with the statement that training needs to be done frequently to see results.

It declines because the heart may beat less frequently since more blood is pumped per beat.

Answer: What happens to resting HR as stroke volume increases?

As stroke volume (the amount of blood pumped by the heart per beat) increases, the heart becomes more efficient at delivering blood. To maintain the same cardiac output, a more efficient heart can beat less frequently. Therefore, an increase in stroke volume typically leads to a decrease in resting heart rate.

In plyometrics it is the amount of time it takes to change direction from eccentric to concentric. ought to be as brief as feasible. to maximize training adaptations (0.1s).

Answer: What is the amortization phase?

In plyometric training, the amortization phase is the critical, brief period between the eccentric (muscle lengthening) and concentric (muscle shortening) contractions. It represents the time it takes to reverse the motion. A shorter amortization phase (ideally <0.1s) is crucial for maximizing the effectiveness of the stretch-shortening cycle and enhancing power output.

A minimal need for participation in programs of moderate intensity exercise. enables participants to assess their own level of medical fitness. poorly screens for those who are at low to moderate risk.

Answer: What is the PAR-Q? Limitation?

The Physical Activity Readiness Questionnaire (PAR-Q) is a self-screening tool designed to identify individuals who should consult a doctor before starting or increasing physical activity. While it's a minimal requirement for moderate exercise, its primary limitation is that it poorly screens for those at low to moderate risk, as it mainly flags individuals with known medical conditions.

Influence based on reward and punishment. capitalize productivity and efficiency. Answer: 3 assessments for muscular endurance

Answer: FALSE

The description 'Influence based on reward and punishment. capitalize productivity and efficiency' refers to a transactional leadership style or a motivational approach, not to assessments for muscular endurance. Muscular endurance assessments typically involve tests like push-ups, sit-ups, or timed bodyweight exercises to measure the ability of a muscle or group of muscles to sustain repeated contractions.

Stroke volume is significantly increased during eccentric phase Answer: stroke volume and eccentric phase

Answer: TRUE

During the eccentric phase of muscle contraction, where the muscle lengthens under tension, there can be a significant increase in stroke volume. This is often due to higher venous return and greater cardiac filling, which allows the heart to pump more blood per beat. This physiological response contributes to the cardiovascular adaptations seen with eccentric exercise.
