Quadrathlon Power Test Calculator

The Quadrathlon (or Quad test) is a series of four power tests, originally devised in 1982 by Max Jones, a throwing event coach for England's track and field team, to test for explosive power improvement of the national throws squad (javelin, shot-put, discus, hammer throwers). The four events of the quadrathlon are the standing long jump, 3-hop test, 30m sprint and the overhead shot throw. This series of tests were developed to measure the athlete's level of speed, strength, explosiveness, and power.

The Four Tests of the Quadrathlon

• Standing long jump — jump off two legs into a sand pit for maximal distance.
• 3-hop test — three consecutive horizontal double-leg jumps, taking off both legs at once.
• 30m sprint — running speed test over 30 meters.
• Overhead shot throw — start facing away from the throwing direction. Bend legs, then drive upwards to throw the shot back over the head to achieve maximum horizontal distance. Use a 16lbs. (male) or 12 lbs. (female) shot put.

Scoring the Quadrathlon Test

The athlete gets three attempts at each test, with the greatest distance or fastest time recorded for each used in the scoring procedure. Points are allocated from the Quadrathlon points table depending on the distance or time achieved for each activity. You can also use these equations to determine the points for each test, where D and T are the distance and time result for the tests:

• Standing Long Jump Points = -36.14048 + (D × 37.268536) + (D² × -0.128057)
• Three Hop Test Points = -36.36996 + (D × 12.478922) + (D² × -0.007423)
• 30-meter Sprint Points = 209.70039 + (T × -36.94427)+ (T² × 0.165766)
• Overhead Shot Throw Points = -22.32216 + (D × 5.8318756) + (D² × -0.000334)

How to Use This Calculator

The Quadrathlon calculator lets you convert your results from all four power events into a single combined points score. Follow these steps to get an accurate reading of your explosive athletic power:

1. Perform each test — complete the standing long jump, 3-hop test, 30m sprint, and overhead shot throw, each with three attempts. Record your best distance or fastest time for each event.
2. Choose your units — the calculator defaults to metric (meters). If you prefer imperial units (feet), toggle the switch above the inputs. Times are always entered in seconds.
3. Enter your results — input your best standing long jump distance, 3-hop distance, 30m sprint time, and overhead shot throw distance into the matching fields.
4. Calculate your score — click the green Calculate button. The calculator applies the original Max Jones polynomial equations to convert each result into points.
5. Interpret your results — each event returns a points total (usually in the 0-100 range), and the four are summed to give your overall Quadrathlon score. Compare against elite benchmarks listed above.

For best accuracy, perform all four tests on the same day after a thorough warm-up. Rest 2-3 minutes between attempts and ensure consistent technique. The calculator works entirely offline in your browser — no data is stored or transmitted.

Understanding Your Quadrathlon Score

Your total Quadrathlon score is the sum of points from all four events. Each event is scored independently using a quadratic equation fitted to the Max Jones points table, with points typically ranging from near 0 for novice performance up to approximately 100+ for elite-level results.

General score interpretation guidelines for trained athletes:

• Elite (300+ total points) — world-class explosive power; this range includes Olympic decathletes and top throwers.
• Excellent (250-299 points) — national-level athletic power across speed, jumping and throwing qualities.
• Good (200-249 points) — well-developed power for competitive club athletes and many team-sport players.
• Average (150-199 points) — typical recreational athlete or untrained active adult.
• Below average (under 150 points) — indicates significant scope for developing explosive power.

Look at the breakdown as well as the total. A strong sprint time combined with a low shot throw suggests relative underdevelopment of upper-body power, while the opposite pattern is typical of pure throwers. Balanced scoring across all four events is characteristic of multi-event athletes.

The Science Behind the Quadrathlon

The Quadrathlon was created because no single field test captures the full picture of athletic power. Max Jones selected four events that together sample lower-body horizontal power (long jump and 3-hop), whole-body reactive power (overhead shot), and horizontal sprinting power (30m). The battery design follows the same logic used in multi-event scoring: combine complementary performance qualities into a single aggregated score.

The scoring equations used in this calculator are quadratic regressions of the form Points = a + (X × b) + (X² × c), fitted to the original Max Jones points tables. Quadratic functions capture the diminishing returns at the elite end of each event — the curve flattens out so that further improvements in already-excellent performance yield proportionally fewer points.

Research by Stauffer and colleagues at the University of Pittsburgh evaluated the Max Jones Quadrathlon against established laboratory measures of anaerobic power, specifically the vertical jump and Wingate cycle ergometer test. Their work supports the Quadrathlon as a practical, field-based alternative for assessing anaerobic power in athletic populations where lab testing is not feasible.

Sport-Specific Applications

Although originally designed for throwing events, the Quadrathlon has become a standard power assessment across many sports:

• Throwing events (shot-put, discus, javelin, hammer) — the original target population. The overhead shot throw is especially relevant to throwers, while the sprint and jumps assess general ballistic power development.
• Decathlon and heptathlon — multi-event athletes like Daley Thompson, Tom Pappas, Trey Hardee and Bryan Clay have all scored highly. The battery mirrors the power demands of decathlon jumping and throwing events.
• Sprinting — elite sprinters like Justin Gatlin and Linford Christie score very well on the sprint and jump components, with lower (but still respectable) shot-throw scores.
• American football, rugby, basketball — sports demanding explosive acceleration, jumping and throwing/striking power map well onto the four events. Coaches use the battery to benchmark off-season power development.
• Collegiate and high-school athletics — the Quadrathlon requires minimal equipment (a sand pit or marked surface, tape, stopwatch, shot) and can be run on a track and field facility in under an hour, making it practical for team-wide testing.

Coaches typically re-test every 4-8 weeks during the preparation phase to track power development and adjust training emphasis. A drop in a single event's points score despite improvements elsewhere is a useful red flag for weaknesses needing targeted work.

How to Improve Your Quadrathlon Score

Improvements come from targeting the specific power qualities each event assesses:

• Standing long jump — develop horizontal concentric leg power through box jumps, broad jumps, squat jumps, and Olympic lift variants (power clean, hang snatch). Perfect your arm swing and hip drive technique.
• 3-hop test — emphasize reactive strength with bounding, depth jumps, repeated broad jumps and hurdle jumps. This event rewards efficient elastic energy use between ground contacts.
• 30m sprint — work on acceleration mechanics with resisted sprints, starts, and short accelerations (10-30m). Posterior chain strength (squats, deadlifts, hip thrusts) transfers directly.
• Overhead shot throw — train whole-body triple extension with overhead med ball throws, rotational throws, and heavy cleans/snatches. The shot throw rewards total-body ballistic coordination rather than pure upper-body strength.

A balanced power programme — combining Olympic lift variants, heavy strength work, plyometrics, and sprint work — tends to lift all four event scores simultaneously. Avoid chasing single-event improvements at the expense of the others.
