Skill, skill continuums and transfer of skills: Gross – fine.

The idea

The gross–fine continuum classifies skills by the size of the muscle groups and the precision of movement they demand. At the gross end, large muscle groups produce big, powerful actions, such as a shot putter driving the whole body through a heavy throw. At the fine end, small muscle groups control delicate, accurate movements, such as a gymnast adjusting finger and wrist position on the apparatus. Most sports skills sit somewhere between the poles: a tennis serve uses large leg and trunk muscles for power but also fine wrist and finger control for placement. When classifying a skill, ask which muscle groups dominate and how much precision is required, then place the skill nearer the gross or fine end and justify the position with evidence from the action.

What earns the marks

• Gross skills are characterised by the recruitment of large muscle groups to produce forceful, whole-body movements.
• Fine skills are characterised by the recruitment of small muscle groups to produce precise, controlled movements.
• The continuum is a scale rather than two separate boxes, so a skill can sit between the poles.
• Classification should be justified by identifying the dominant muscle groups and the precision demanded by the action.
• A shot put throw illustrates the gross end because large muscle groups generate force.
• A gymnast adjusting finger and wrist position illustrates the fine end because small muscle groups control accuracy.

Common mistakes and how to put them right

• Treating gross and fine as two fixed categories rather than opposite ends of one continuum.

  Put it right: Place each skill at a point on the scale and justify that position.

• Assuming that a sport is wholly gross or wholly fine.

  Put it right: Classify the specific skill, because one sport can contain skills at different points.

• Judging the continuum by how difficult the skill looks rather than by muscle-group size and precision.

  Put it right: Use the defining criteria of muscle groups and accuracy.

• Believing that fine skills never involve force.

  Put it right: Fine skills still produce movement but rely on small muscle groups for precision.

Exam tips

• Name the dominant muscle groups in the skill before choosing a position on the continuum.
• Use a specific sporting example and explain why it sits nearer one end.
• If a skill has both elements, say so and explain which element dominates and why.
