Eight-Week Speed Block for Tactical Team Selection
A 34-year-old corrections officer has 8 weeks until tactical team selection. The test is a 1.5-mile run, 40-yard sprint, 6 ft chain-link fence, 165 lb dummy drag, 25 push-ups, and 30 sit-ups. Current results: 1.5-mile 12:45, 40-yard 5.6 seconds, vertical jump 18 in, trap-bar deadlift 1RM 315 lb, body mass 190 lb, estimated 18% body fat. He lifts four days per week in a bodybuilding style, has not sprinted in five years, and had a grade I hamstring strain three years ago. He works 12-hour shifts rotating between days and nights, with two days off. The gym has a trap bar, turf, and a sled; outdoor space is available. He wants to improve his sprint and keep his strength, but his hamstrings tighten after sprint sessions. Selection is competitive; only the top 60% advance.
1. Design the 8-week speed and power progression, including weekly frequency, sets, reps, and how lifting is reduced.
Read the worked answer
Use two high-intensity days and two lifting days, keeping total volume low.
- Weeks 1–2 (mechanics): Day 1 - warm-up, 4×20 m accelerations at 90%, 3×40 m at 90%, trap-bar jump 3×3 at 30–40% 1RM, sled push 3×15 m. Day 2 - 6×10 m starts, 3×5 broad jumps, Nordic curl 3×5, hip hinge 3×8.
- Weeks 3–5 (intensification): Day 1 - 3×40 yd at 95% with full recovery, 3×3 trap-bar jump, 2×20 m sled. Day 2 - 4×30 m fly, 3×5 single-leg hop, Nordic 3×6.
- Weeks 6–7 (peak): one timed 40 yd and one short sprint session; reduce lifting volume 40%.
- Week 8: taper - 2×20 m at 90%, no soreness.
Keep trap-bar deadlift 2×3 at 85% and push-ups/sit-ups once weekly. Sprint volume should not exceed roughly 200–250 m per session initially. The goal is faster 40-yard time without accumulating bodybuilding volume that blunts speed.
2. What hamstring risk-management steps are required given his prior strain and five years without sprinting?
Read the worked answer
Require a 15-minute warm-up with progressive skips, A-marches, and 2×20 m build-ups. Start sprint volume low (80–120 m), progress 10–20% weekly, and never sprint after a 12-hour night shift or with sleep <5 hours. Nordics and hip hinges twice weekly; stop the session if hamstring tightness changes gait. Use the 40-yard test as an exposure, not a maximal effort every week. Because he has a prior grade I strain, the first two weeks are mechanics and submaximal exposures, not timed efforts.
3. How do you adjust the plan for rotating 12-hour shifts without losing the speed stimulus?
Read the worked answer
After a night shift, move the high-intensity session to after 6–7 hours of sleep, or replace it with low-volume mechanics at 80%. Use a readiness rule: resting heart rate +7 bpm or sleep <5 hours means cutting volume 30–40% and removing the sled. Because selection is in 8 weeks, do not add a third sprint day; protect the two quality days. If hamstrings remain tight for >48 hours, reduce fly volume and keep one acceleration day. This preserves the speed stimulus while managing fatigue from shift work.
