Anna Espenschade: notating and analysing field hockey in 1936

Introduction

Anna Espenschade is rarely mentioned in the discussion of performance analysis in field hockey.

I have reported her work in Clyde Street posts but in the context of basketball (with Nancy Miner and Pauline Hodgson, 1940).

I have no excuse for missing her 1936 paper on field hockey. In her valedictory article for Anna, Roberta Park (2000:100) notes that Anna had been involved in field hockey from 1920 and was named left halfback on the All United States Reserve Field Hockey Team in 1925 (2000:103). She was Chair of the Pacific Southwest Section of the United States Field Hockey Association (USFHA), was involved in the development of officiating and became a National ‘A’ umpire. She was vice president of the USFHA 1938-1940 (2000:103).

Roberta makes explicit mention of Anna’s hockey paper in her summary of Anna’s publications (2000:107) and it is included as reference 93 (2000:114). Roberta would have known Anna well. Roberta was a colleague of Anna’s, at the University of California, Berkeley, from the mid-1950s when she was appointed as an assistant supervisor in physical education. Anna had been at the University for two decades prior to Roberta’s arrival on the staff.

Recording Field Hockey

Anna’s 1936 paper, An Analysis of Activity Records of Field Hockey Players, appears in volume 7(3) of the Research Quarterly (pp.62-74).

The paper reports information from 500 records of positional play (1936:63). 48 players (from three ability groups) were observed during the study.

Literature review

Anna notes in the introduction to her paper “no studies have been made to determine whether or not all positions with the exception of goalkeeper are equally strenuous” (1936:62). Her paper includes one reference: Lloyd Messersmith and Stephen Corey, 1931, The Distance Traversed by a Basketball Player.

Purpose

The purpose of her paper was “to determine the distances traveled and the rate of speed of movement of players in the various positions of the field hockey team”. (1936:62)

Delimitation

Anna delimited her study to five field positions: center forward, right and left halfback, right and left fullback. She noted that “some of these positions were studied more thoroughly than others”. (1936:62)

Methodology

The paper reports data collected in real-time by two research assistants, Mildred Martin and Mae Moore. Mildred and Mae stood on a terrace above the hockey field (possibly the terrace shown in this picture of the Hearst Gym West Field from the late 1940s).

They traced the path of players on a scaled sheet of stiff cardboard (the scale used was eleven yards to the inch) fixed to a drawing board. Translucent onion-skin paper was overlaid on the cardboard template of the field. They tracked players for a three-minute interval (“the longest time period practical for making legible records” and “it divided the official sixty-minute game into a convenient number of parts” (1936:62)).

Each sheet contained: name and field position of player observed; date; path of player; number of times the ball was played; number of seconds rested. (1936:63)

The notation of the three-minute intervals included “a small circle … each time the player under observation hit the ball”. (1936:62) A stopwatch was used to time when players under observation stood still.

Observer agreement

Anna reports the practice undertaken to ensure and assure the accuracy of the records taken by Mildred and Mae. (1936:63)

I take it from her discussion that she focused on inter-observer agreement as there is no explicit mention of intra-observer agreement procedures. Anna used an agreement within 5 per cent of total distance and time for simultaneous records. She notes that after four weeks of consistent practice, forty-five minutes of records “showed an average deviation from the mean in time of 1.6 per cent; in distance of 5.4 per cent”. (1936:63) She provides information about subsequent accuracy measures.

The distances notated by the observers was measured “at least four different times” by two students. If their inter-observer agreement exceeded 5 per cent of the total additional measurements were made. (1936:63)

Distances traveled

Anna reported these data:

Visualisation of data

Anna’s paper includes a number of visualisations:

Positional tracks (1936:67)

Areas covered (1936:68)

Distances (1936:71)

Conclusion

Anna concludes her paper with eleven summary points. These make fascinating reading for anyone interested in movement patterns in field hockey.

Reflection on Anna’s work

I am disappointed to have overlooked this paper for so long. It is an important paper in the history of notational analysis. Elsewhere on Clyde Street, I have written about other researchers in the 1930s and their interest in distances traveled and traversed. I have mentioned Anna in these accounts.

Anna’s field hockey paper stands in the middle of a decade of research. Anna cites Lloyd Messersmith and Stephen Corey (1931). Lloyd and Stephen’s paper has no reference to earlier work. Anna’s (1940) paper co-authored with Pauline Hodgson and Nancy Miner, used some of the tracking methodologies reported in her 1936 paper. The 1940 paper refers to two earlier papers by Pauline (1936, 1939) but not to Anna’s 1936 paper.

All of these are important primary source material as we contemplate our methodologies in quite a different age, but one that stands upon the shoulders of these pioneers.
