Q

Purpose of pace/tempo training

A

Purpose:
To stress the athlete at a specific intensity & improve energy production from both aerobic & anaerobic metabolism.

24
Q

2 types of pace/tempo

A

Steady Pace/Tempo Training

Intermittent Pace/Tempo Training

25
Q

Steady Pace/Tempo Training

A

Continuous training conducted at an intensity equal to the lactate threshold for durations of ~ 20-30 min.

26
Q

Intermittent Pace/Tempo Training

A

Training session is composed of a series of work:recovery periods.

short work and brief recovery

steady intensity

27
Q

HIIT has (short/long) recovery periods.

A

short (brief)

28
Q

Work intervals for HIIT are?

A

can either be short or long intervals

29
Q

Cross-Training

A

is a mode of training that can be used to maintain general conditioning in athletes during:

periods of reduced training due to injury or

recovery from a training cycle.

30
Q

Detraining occurs when?

A

occurs when an athlete reduces training frequency, duration, and/or intensity, or stops training altogether due to a break in the training program, injury, or illness.

31
Q

Tapering

A

is the systematic reduction of training duration & intensity, combined with an increased emphasis on technique work & nutritional intervention.

32
Q

Tapering objective

A

To attain peak performance at the time of competition.

33
Q

Typical tapering period

A

7-28 days

34
Q

benefit of tapering

A

Helps facilitate recovery & rehydration.

Promotes increases in muscle & liver glycogen stores.

35
Q

Linear tapering

A

a gradual decrease in the overall daily training volume throughout the duration of the taper.

36
Q

Step Tapering Model

A

an abrupt & considerable reduction (≥ 50%) in training volume that is maintained throughout the duration of the taper without change.

37
Q

Progressive Tapering Model

A

is a combination of the linear & step tapering models.

rapid 10% to 15% immediate reduction in training volume, with smaller, more gradual reductions in volume at each tier.

partial, not full, recovery

48
Q

HIT improves endurance performance to a greater extent than continuous ________ training alone. Why?

Increased expression of type 1 fibres.
Increased capillarisation.
Increased oxidative enzyme activity.

50
Q

decreases

increases everything else basically!

51
Q

Central adaptions to HIT

Increased oxidative enzyme activity.
Greater use of fatty acids.
Increased glycolytic enzyme activity,
Increased glycogenolytic capacity.
Increased capacity of skeletal muscle to buffer H+ ions.
Altered expression of Na+-K+-ATPase & SR Ca2+-ATPase.
An up- or down-regulation of muscle cation pumps.
Increases in myoglobin stores.
Increased capillary density.
Increased expression of type I fibres.

53
Q

Vmax

A

is a variable that has been used with reasonable success in prescribing endurance exercise training intensities in runners.

is the velocity at which VO2max is achieved.
is defined as the running speed during an incremental test at which VO2max is attained.

has been shown to predict performance in middle- & long-distance running events.
appears useful for prescribing HIT programmes.

54
Q

What is T max

A

The time that an athlete can run at his or her Vmax.

The time to exhaustion at Vmax.

Highly subjective, even amongst runners with the same Vmax.

Fractional utilization of Tmax emerges as an appropriate marker for establishing interval duration.

55
Q

Tmax has been shown to correlate (positively/negatively) with VO2max & Vmax and (negatively/positively) with the anaerobic threshold.

A

negatively

positively with anaerobic threshold

56
