# Talent Evaluation

Studies conducted at Indiana University USA (not published) revealed that it is possible to accurately predict performance in selected track and field events using relatively simple tests.

### Objectives

To assist coaches to recognise the potential of young athletes and predict their performance in selected track and field events. All of the performance tests and calculations are detailed in Rogers (2000)[1]. The following are the basic tests and calculations.

### Tests

The basic tests are undertaken in the order given:

• Male Athletes - Standing long jump, vertical jump, five bounds and standing 30 metres
• Female Athletes - Weight, standing long jump, stride length and stride frequency

#### Standing Long Jump (Male & Female)

The athlete places their feet over the edge of the sandpit. The athlete crouches, leans forward, swings their arms backwards, then jumps horizontally as far as possible, jumping with both feet into the sandpit. The coach should measure from the edge of the sandpit to the nearest point of contact. The start of the jump must be from a static position. Two trials are performed, and the best performance used in the calculations. Result to be in metres.

#### Vertical Jump (Male)

The athlete chalks the end of his fingertips stands side onto the wall, keeping both feet remaining on the ground, reaches up as high as possible with one hand and marks the wall with the tips of the fingers (M1). From a static position, the athlete jumps as high as possible and marks the wall with the chalk on his fingertips (M2) The coach then measures the distance from M1 to M2. Two trials are performed, and the best performance used in the calculations. Result to be in metres.

#### Five Bounds for Distance (Male)

From a stationary position with both feet together the athlete executes 4 bounds and a jump into the sandpit. Measurement is made from the start point to the landing point nearest to the starting line. Two trials are performed, and the best performance used in the calculations. Result to be in metres.

#### Standing 30 metres (Male)

From a standing start, the athlete runs 30 metres. Two trials are performed, and the fastest time is used in the calculations. Result to be in seconds.

#### Stride Frequency (Female)

From a standing start, the athlete runs 60 metres. The time is recorded for athlete to complete 30 metres and 60 metres. The number of strides taken from 30 metres to 60 metres is recorded. The number of strides is divided by the time for the last 30 metres (60 metres time minus the 30 metres time) to give stride frequency. Result to be strides/second.

#### Stride Length (Female)

From a standing start, the athlete runs 60 metres. The number of strides taken from 30 metres to 60 metres is recorded. The number of strides is divided by 30 to give stride length. Result to be in metres.

#### Weight (Female)

Wearing running clothes, not shoes, measure the athlete's weight. Result to be in pounds.

### Male

Enter the test results and then select the "Calculate" button for an analysis.

### Analysis

The IAAF Scoring Tables for Combined Events (edition 2001) are used to estimate performance in a selected event. On the appropriate male event table locate the number of points and read off the distance or time. The 90% confidence levels for each event are detailed below.

### Female

Enter the event results and then select the "Calculate" button for an analysis of the results.
