A partial curl-up protocol for adults based on an analysis of two procedures.

The reliability and objectivity of two curl-up protocols in assessing abdominal muscle endurance were evaluated in 262 adults (18-69 + years of age). The two protocols consisted of the Canada Fitness Award procedure (Type I) and a partial curl-up described by Fitness Canada (Type II). The relationship of these protocols, body mass, trunk flexion, body mass index and waist/hip ratio to the incidence and degree of low back pain also was investigated. Based on the results, Fitness Canada recommended that a modified Type II partial curl-up be considered for adoption into the Canadian Standardized Test of Fitness (CSTF) procedure.
