HIIT Training vs. Plyometrics - Maximize HIIT Workout Results with Plyo- Thomas DeLauer

The misconception that many runners have is that each fiber type is exclusive i. In reality, with the right training, we can manipulate and improve all three. Before we can outline how to improve fiber function and conversion, we must understand under what circumstances we use each fiber type, when they are recruited, and when they change. This process starts with what we call the recruitment ladder. The recruitment ladder is a way of envisioning how and when each fiber type is activated. At the bottom of the ladder, we have the slowest, least explosive fiber type, Type I slow-twitch, and at the top you have fast-twitch fibers.

You move up the ladder based on how much force you need to generate to sustain a given pace. If you were to head out to the streets right now and begin running easy, your body would start by using slow-twitch fibers. If you were to pick up the pace, your body would start recruiting some of the Type IIa intermediate fibers to supplement the need for more power from the muscles to generate more force during the stride. Finally, if you were to sprint across the road to beat traffic, your body would then engage the fast twitch muscle fibers to give you the explosive burst you need to sprint. As a consequence, you start to recruit some intermediate fibers to help maintain pace.

Now that we better understand the different muscle fiber types and under what circumstances we use them, we can employ this knowledge to better structure our training. The long run targets the slow-twitch fibers, making them more efficient by building their aerobic capabilities, and also making them more fatigue-resistant. Continuous long runs also help convert a greater percentage of your muscle fibers into slow-twitch fibers, which is one reason you continue to get better with years of mileage.

Tempo runs target slow-twitch and intermediate muscle fibers. Slow-twitch fibers reach maximum recruitment and contraction speed at tempo pace, which is one reason why tempo runs are so critical to endurance training. In addition, tempo runs help improve the recruitment patterns of intermediate fibers with slow twitch fibers. In essence, it improves the ability of both fiber types to work together for maximum effectiveness. Traditional interval workouts like 12 x meters help recruit intermediate and fast twitch muscle fibers. By being used together, these two fiber types learn to interact more efficiently by reducing activation of unnecessary fibers.

More importantly, it improves our neuromuscular coordination — the speed at which the brain can send signals to the muscles to fire, thus making you more efficient. There are also several potential disadvantages to the linear program. The linear program was originally devised as a training model for preparing for one peak competition per year in Olympic weightlifters. Another potential disadvantage is that maintenance of specific training parameters is difficult once an athlete transitions to another phase.

Unfortunately, all of these potential advantages and disadvantages are speculative at this time. These more frequent changes may be highly conducive to strength gains. There are many potential advantages to the NP approach, although no definitive conclusions can be made at this time. First of all, the weekly fluctuations in training loads may lead to better neuromuscular adaptations compared to the LP approach, as loads are more unpredictable.

Additionally, in the NP model, several training parameters may be addressed at the same time. Therefore, an athlete may address power and strength within the same week. Finally, due to the concurrent nature of the training, the detraining effects that occur in a LP approach might be avoided. Like LP, there are a few potential disadvantages for the NP approach. Particularly in the recovering athlete, the athlete may not be appropriate for lifts focusing on power development, like the clean and snatch, if an appropriate strength base has yet to be achieved or established.

Finally, the NP program may not allow each performance characteristic to be optimally developed due to focus on several parameters at once. Again, definitive conclusions cannot be made at this time about the advantages or disadvantages to the NP approach. The results suggest that novelty or training variety are important for stimulating further strength development. To date, most authors have found only minimal differences in strength and power measures between LP and NP. Although there were subtle differences in outcome measures studied, but these differences were not statistically significant. No definitive conclusions can be made at this time as to which method is preferred.

Block periodization is an approach to the periodization of strength that has experienced a renewed interest of late. Each step in the training cycle has a large volume of exercises focused on specific, targeted training abilities to ensure maximum adaptation. The LP model increases basic qualities, but these tend to decline during the competitive season.

The block system allows for these qualities to be maintained throughout the year. In the block approach, if an athlete doesn't require endurance for their sport, it is not a focus of training. Similarly, the block approach would not include balance, strength, and agility in one training block — they would be performed separately with a specific focus. Because these exercises comprise two different training modalities strength and power , they would not be performed simultaneously. On the contrary, complex training would be used in an LP or NP programs. In other words, an athlete may do strength, power, and peaking within four weeks while it may be several months before each phase is completed in the LP or NP because they are of longer duration.

The block approach is divided into three distinct phases. Untrained athletes would require more time in this phase. The second phase is the transmutation phase. Accommodating resistance, like the use of chains or elastic bands with squats, may be used to promote a strength overload. For example, accommodating resistance in not typically used in this phase. There are a few studies that have utilized the block approach compared to other approaches. Another study by Bartolomei et al 60 found there were no differences between the block and a more traditional LP program on upper and lower body strength in trained athletes.

Compared to the LP approach block training was found to be a superior method of training by Ronnstad et al 61 in a group of cyclists for VO2max and power output, Ronnstad and others 62 in a group of elite cross country skiers for peak power and maximal oxygen uptake, and by Breil and coauthors 63 in elite junior alpine skiers. Interestingly, two studies found that the block program lead to greater improvements in strength per volume of load when compared to other programs. In summary, block periodization is showing some promise when compared to more common approaches like LP and NP.

The positive results may be partially explained by the fact that the block periodization studies were short in duration and the intensity was high. The intensity seemed to be a direct correlate to performance. Furthermore, it appears that the block program was indeed better for athletes who have multiple events per year cycling, skiing, track, etc. More research is needed before definitive conclusions can be made. The periodization schemes laid out previously define methods of sequencing the training process over time.

In turn, the creation of the specific program within the selected periodization scheme drives the desired adaptations. This process is built around the principles of overload, variation, and specificity. Overload is described as a stimulus of sufficient strength, duration, and frequency as such that it forces an organism to adapt. These variables are traditionally considered to be the exercise type, the order performed, the intensity percentage of repetition maximum prescribed, as well as the sets, repetitions and rest periods assigned.

Siff and Verkoshansky laid out a number of considerations for addressing mechanical specificity such as looking at the movement's amplitude and direction, the dynamics of the effort, the rates of force development, and contraction types. When viewed from a bioenergetics perspective, a task analysis must be performed and the identified demands on the energy systems should be reflected in the programming.

A growing body of literature exists specific to the energy system demands of sport. The rehabilitation programming should be structured to prepare the athlete for the metabolic demands of their specific sport. Without monitoring and adaptation the most elegant program can quickly become irrelevant. Furthermore, the sports physical therapist has the added challenge of dealing with the healing process.

While adherence to a consistent approach will drive adaptation, structured variability is also necessary within this framework to ensure relevance on any given day. Because of this, a method of programming that is modifiable based on relevant feedback is important. One such method is autoregulation, a modification of the daily adjusted progressive resistive exercise DAPRE system that allows for a more flexible application than more traditional approaches. This approach has been applied successfully in both rehabilitation and performance based settings and has been shown to actually outperform more standard methods of periodization in some cases.

Other models exist to estimate 1RM without actually lifting a true 1RM such as the Oddvar Holten Curve 74 and other models by Baechle et al which are used to establish an estimated 1RM based off of submaximal loads taken to failure. Research at this point is still emerging but a few practical models have been developed that determine intensity based on the velocity of the bar during the lift and the end of the set being based on a predetermined decrease in velocity. Strength should be considered fundamental to all other aspects of training and forms the foundation of most successful return to play RTP approaches. Strength is closely correlated with the capacity to rapidly produce high levels of force and as a result maximal force development should be the initial emphasis with those presenting with lower levels of strength.

This brief review of strength principles highlighted some of the considerations that the sports rehabilitation professional must consider when programming within any of the periodization schemes. Practical recommendations for strength training loads are presented in Table 7. Many aspects of sport and daily life require the ability to produce relatively high levels of force in a brief period of time. This characteristic is commonly described as power although there are some concerns that this term may not be as accurate as the biomechanical term, impulse.

Power is defined as the rate at which work is performed and is the product of force and velocity. As a result it becomes apparent that the ability to apply high levels of force in a brief period of time and to contract at high velocities are vital components of its development. Power development can be subdivided into a focus on muscular strength, rate of force development, and maximal force at high velocities of movement. Regardless of the specifics, maximal strength levels constrain the upper limits of maximal power output. The ability to generate force rapidly is of little use if the level of force generated is below a necessary threshold and thus adequate strength levels form the foundation of maximal neuromuscular power development. Cormie et al randomized individuals into groups based on their squat 1RM to body mass ratio.

As a result, the authors concluded that there is potential benefit to developing strength initially before performing a focused ballistic program. There is a paucity of data with regard to power development or training in the upper body, but the same trend for stronger athletes to respond better to ballistic work compared to their weaker counterparts has also been seen.

Young et al found that athletes with a lower bench press repetition maximum benefited more from strength work, however, those with higher relative strength also benefit from the inclusion of ballistic work. Their findings indicated that the addition of ballistic exercise increased power when compared to strength training alone. Ballistic training, which includes techniques such as jump squats, medicine ball throws, and box jumps has been argued to impact the high velocity area of the force velocity curve.

This is in contrast to power work done with heavier loads, such as the Olympic lifts, which will have a greater effect on the higher force aspect of this relationship. The concept of optimal load training indicates that training loads should be chosen to allow for maximal power output as this is the most effective means of further power development. Table 8 gives some general recommendations for power training intensity zones based on various exercises commonly used for power development. At this time, the research on periodization is limited, not only in the rehabilitation literature but also in strength and conditioning. The block model has not yet been studied in rehabilitation literature. Additionally, use of these periodization models has not been utilized in interval sport programs.
