Explain what the muscles in the legs and arms feel like (e.g., they feel tired, they feel hard and tight) when involved in sustained and/or repeated movement activity.

Sustain participation in moderate to vigorous locomotor activities (e.g., walking, running, dancing, snowshoeing, cross-country skiing, swimming, parachute play) and lead-up games (e.g., tag games, follow-the-leader) that increase heart rate and respiration rate, for six consecutive minutes on a consistent basis.

Identify and participate in movement activities that challenge and support muscular endurance and muscular strength (e.g., imitating animal walks, moving while carrying weighted objects such as heavy books, holding balances and other stable positions such as a push-up with arms extended).

Demonstrate an understanding of how muscles and joints move during movement activity through verbal and movement explanation, and/or visual displays such as pictures and drawings.

Explain why heart rate and breathing rate increase during moderate to vigorous activity.

Practise, with guidance, a dynamic stretching (see glossary) routine as a means to warm up.

Explain how dynamic stretching can enhance movement and help to protect the body from injury over the long term.

Recognize and participate in safe and effective movement activities that are good for flexibility (e.g., stretching exercises such as yoga) and that can help to prepare muscles for vigorous activity (e.g., warm-up activities increase blood circulation and stretchiness of muscles and ligaments).

Engage, on a daily basis, in a variety of movement activities that benefit health-related fitness.

Determine own degree of exertion (e.g., put hand on chest to feel increased heart rate, talk test – more exertion means it will be harder to talk, try to feel pulse in neck) and express thoughts about own degree of exertion after participation in movement activities.
