I will be at the NSCA Sport-Specific Training Conference in Orlando this weekend. I have a short 20-minute “From the Field” presentation on Friday at 12:20, where I’ll talk about overload-underload training and drills for bat speed development. Send me a message if you’ll be there…….
The Bratt Bat has been around for a long time and if you pay attention you can probably see one in the on-deck circle of most major league baseball teams. Although Bratt Bat’s are traditionally used as a warm-up device, I think they can also serve a purpose for learning specific areas of the swing, such as rotation and swing path. Even though these heavy weighted bats are out of the suggested range for use with standard overload-underload bat speed training, they still can be an effective tool for teaching mechanics that generate power and increased bat speed.

Swingtraining.net has joined with Perfect Competition sports performance facility in order to provide comprehensive strength, speed, and hitting specific workout programs in the Southeast Florida area. Perfect Competition already has a well established reputation for their MLB Performance Enhancement program, and now Swingtraining.net will add the most specific hitting training available.
Below is another bat speed training research abstract. This really was one of the best, if not the best, controlled research study that has been published regarding overload & underload training and its effects on bat swing velocity – and it was done all the way back in 1995!
The basics are that 3 groups of 20 college players were trained 4 times per week for 12 weeks under the following conditions: batting practice group, dry swing group, control group. The BP and dry swing group followed this swing training protocol using varied heavy and light weighted bats while the control group just dry swung with a regular weighted bat.
The results say that each group significantly imrpoved bat speed, but that’s a little misleading if you don’t read the whole study. The batting practice group improved 10%, the dry swing group imroved 6%, and the control group improved 1%.
Pasted below is the abstract from a bat speed training article published by Chester Sergo and Douglas Boatwright in 1993. The italics and red text are emphasis added by me. Read the abstract, but I’ll summarize and make a few points:
- 24 subjects averaged 19-20 years old and were college students practicing in the off-season
- All the training was done with just dry swings, during practice. 100 swings in sets of 20 performed 3x/week for 6 weeks
- Group 1 (regular bat only), Group 2 (62 oz. bat), Group 3 (alternated sets with 62 oz. & fungo bat)
- Each group improved bat speed 8-9%, with no statistically significant difference. Group 1 (8.8%, highest), Group 2 (8.0% lowest), Group 3 (8.2 %)
- FYI the average bat speeds reported for these players began in the low 90′s and ended around 100 mph, measured by some light timing device made by the school’s engineering department
This video clip is of a college player who was looking for a way to improve after a redshirt freshman year at a Division I baseball school. I’d say he figured it out! This is one of the most drastic improvements I’ve seen in such a very short period of time. Bat speed work with overload-underload bats, reaction and timing training, several different drills for rotation and swing path…we did it all:
