Question

HLPaper 1B

A cross-sectional study involving over 200 elite and sub-elite endurance athletes examined their preference for various recovery modalities. The aim was to understand patterns in usage and rationale for techniques such as massage, sleep, compression garments, and cold water immersion, based on sex, event type, and competition level.

Figures 1 to 3 summarize the reported use of these methods across different population segments.

Figure 1: Recovery Modalities: Sex-Based Usage

Figure 2: Recovery Modalities by Discipline

Figure 3: Recovery Modalities by Competitive Tier

(a)

Based on Figure 1, which recovery method was most widely adopted overall, and by how many more men than women used this method?

[2]

(b)

Using Figure 1 only, the recovery method with the lowest reported usage and one reason it may be less preferred.

(c)

Of racewalkers, middle-distance, and long-distance runners, which reported the highest uptake of sauna bathing?

[1]

(d)

one physiological benefit and one psychological benefit associated with sauna use in recovery.

In hot environments, which factor most increases fatigue risk for marathon runners?

HLPaper 1A

Which physiological process is a characteristic of the fast (alactacid) component of excess post-exercise oxygen consumption (EPOC)?

HLPaper 2

A competitive swimmer trains twice a day. The figure shows the relationship between sleep duration on the night after training and a next-morning recovery marker (countermovement jump).

Figure: Next-morning countermovement jump recovery against sleep duration

(a)

Using the figure, the relationship between sleep duration and next-morning recovery.

[2]

(b)

why sleep is important for recovery from training.
