Who says coffee isn’t good for you, well at least for sports performance! The following high-quality study demonstrates the effectiveness of caffeine on power output (i.e. Explosive lifting, short powerful combat techniques) a few caveats though:
- The recommended dose of 3 mg/kg would equate to 240 mg (about 2 – 3 cappuccinos ), I would not recommend you try and consume 9 mg/kg the side effects as stated might be very uncomfortable.
- Because caffeine content of coffee can vary, to get the best results, it may be best to use caffeine tablets, to ensure you get the correct dose.
ABSTRACT:
Purpose:
The purpose of this study was to determine the oral dose of caffeine needed to increase muscle force and power output during all-out single multijoint movements.
Methods:
Thirteen resistance-trained men underwent a battery of muscle strength and power tests in a randomised, double-blind, crossover design, under four different conditions:
(a) Placebo ingestion (PLAC) or with caffeine ingestion at doses of
(b) 3 mg·kg−1 body weight (CAFF3mg),
(c) 6 mg·kg−1 (CAFF6mg)
(d) 9 mg·kg−1 (CAFF9mg)
The muscle strength and power tests consisted in the measurement of bar displacement velocity and muscle power output during free-weight full-squat (SQ) and bench press (BP) exercises against four incremental loads (25%, 50%, 75%, and 90% one-repetition maximum [1RM]). Cycling peak power output was measured using a 4-s inertial load test. Caffeine side effects were evaluated at the end of each trial and 24 h later.
Results:
Mean propulsive velocity at light loads (25%–50% 1RM) increased significantly above PLAC for all caffeine doses (5.4%–8.5%, P = 0.039–0.003). At the medium load (75% 1RM), CAFF3mg did not improve SQ or BP muscle power or BP velocity. CAFF9mg was needed to enhance BP velocity and SQ power at the heaviest load (90% 1RM) and cycling peak power output (6.8%–11.7%, P = 0.03–0.05). The CAFF9mg trial drastically increased the frequency of the adverse side effects (15%–62%).
Conclusions:
The ergogenic dose of caffeine required to enhance neuromuscular performance during a single all-out contraction depends on the magnitude of load used. A dose of 3 mg·kg−1 is enough to improve high-velocity muscle actions against low loads, whereas a higher caffeine dose (9 mg·kg−1) is necessary against high loads, despite the appearance of adverse side effects.
