Alice Irwin Young, 42, a physical education teacher and coach at the Holton-Arms School in Bethesda, died of cancer Friday at Suburban Hospital.

Mrs. Young had played on national and regional lacrosse and field hockey teams before joining the school in 1969. She introduced lacrosse to the school and served as coach of its lacrosse team.

She was born in Philadelphia and earned a bachelor's degree in physical education from Ursinus College in Collegeville, Pa., in 1959.

In 1957, she was a member of the U.S. Lacrosse Team. The following year, she played on the All-College and Philadelphia No. 1 field hockey teams.

Mrs. Young also played for the Washington Field Hockey Association and was a member of the Southeast No. 1 field hockey team from 1959 to 1964.

In 1963, she coached the American University women's field hockey team.

She was director of the Metropolitan Field Hockey and Tennis Day Camp and had been a sectional umpire for the U.S. Field Hockey Association, which qualified her to officiate at international field hockey competitions.

Mrs. Young was a member of the U.S. Field Hockey Association and was active in the Juvenile Diabetes Foundation and the American Diabetes Association.

Survivors include her husband, David A., two daughters, Tamara and Ellen, and two sons, David A. Jr. and Andrew, all of the home in Gaithersburg; her mother, Mrs. James F. Irwin of Bala-Cynwyd, Pa., and a sister, Rugh I. Weidner of West Chester, Pa.

The family suggests that expressions of sympathy be in the form of contributions in her name to the Juvenile Diabetes Foundation, Lanham, Md.
