All of those events are reflected by one measurement: O 2max.

Not all Fitness training adaptations aspire trainnig be adaptatoins athletes, but all people do value the freedom associated with being able to take care of themselves. People engage in training to enhance functional capacity, be it to improve physical performance or simply to improve quality of life.

Mitochondria contain more than 1, different proteins. Training increases the number of mitochondria, antioxidants within mitochondria, and a variety of proteins that protect the muscle cells against stress.

The most important adaptation for athletes is improved performance. Better performance is also an interest of exercise scientists because improving the capacity for exercise is important not only for athletes but also for everyone because improved aerobic fitness is related to a reduced risk of noncommunicable diseases such as heart disease, obesity, and diabetes; improved recovery from surgery; and all the other health-related issues listed in figure 9.

Regular exercise and the improved fitness that results help reduce the risk of many diseases and disorders. Aerobic capacity - as measured by O 2max - reflects the capacity of muscles to produce ATP from the aerobic metabolism of carbohydrate glucose and fat fatty acids.

To improve fitness and endurance performance, the ability to produce ATP aerobically has to increase. That ability is reflected in O 2max. The higher the O 2maxthe greater the ability to produce - and continue to produce - ATP.

As mentioned, the athlete with the highest O 2max does not always finish first. Many other factors interact to determine overall athletic success; in endurance sports, O 2max is just one of those factors.

However, it is one of the major factors in the ability to complete endurance events. Athletes and clients who want to improve their endurance have to complete the right amount and type of training in order to reach their performance goals. Figure 9. Training programs - including nutrition, hydration, and rest - should improve all of these responses.

Factors that determine O 2max. An obvious answer to this question is training. Adhering to an endurance training program is perhaps the single most important factor that determines how much aerobic capacity O 2max improves. However, individual response to an aerobic training program can vary.

Larry Kenney. Why Is O 2max So Important for Endurance? What Factors Determine How Much Aerobic Capacity Improves? Following are key factors that combine to determine the overall improvement in O 2max : Initial fitness.

An athlete with a high O 2max before training will have a smaller improvement than an athlete who begins training with a low O 2max. Genes establish the upper limit of improvement in O 2max as the result of training.

High or low responder. Genetics heredity also determines the extent to which people respond to training. High responders improve quickly and to a greater extent than low responders.

Even after O 2max plateaus with training, endurance performance can still improve in terms of movement economy and anaerobic threshold.

Proper rest intervals are important for maximizing tension, both between exercises and training sessions. Insufficient rest results in inadequate recovery and a diminished capacity of the muscle to exert full force.

Unfortunately, the ideal rest interval between exercises has not been determined. Most athletes strength train three to four days per week with large muscle exercises, such as the squat and bench press, rarely done more than twice a week. This practice has been empirically derived.

It allows adequate recovery between training sessions. The overload must be progressively increased for consistent gains in strength to occur. However, because of the high dangers of over-training in strength building exercises, constantly increasing the resistance is sometimes counter-productive.

A relatively new practice among strength trained athletes is periodization of training. This practice varies the volume and intensity of exercises so the nature of the exercise stress frequently changes.

Many athletes believe that this practice produces a faster rate of adaptation. Periodization of training will be discussed further in the section on the progressive resistance training programs of athletes.

Muscles adapt specifically to the nature of the exercise stress. The progressive resistance training program should stress the muscles how they are to perform. The most obvious example of specificity is that the muscle exercised is the muscle that adapts to training. Thus, if you exercise the leg muscles, they hypertrophy rather than the muscles of the shoulders.

There is specific recruitment of motor units within a muscle depending upon the requirements of the contraction. The different muscle fiber types have characteristic contractile properties.

The slow twitch fibers are relatively fatigue-resistant, but have a lower tension capacity than the fast twitch fibers.

The fast twitch fibers can contract more rapidly and forcefully, but they also fatigue rapidly. The use of a motor unit is dependent on the threshold levels of its alpha motor neuron. The low threshold, slow twitch fibers are recruited for low intensity activities such as jogging and for that matter, most tasks of human motion.

However, for high speed or high intensity activities, such as weight lifting, the fast twitch motor units are recruited. The amount of training that occurs in a muscle fiber is determined by the extent that it is recruited.

High repetition, low intensity exercise, such as distance running, uses mainly slow twitch fibers. Endurance training improves the fibers' oxidative capacity.

Low repetition, high intensity activity, such as weight training, causes hypertrophy of fast twitch fibers. There are some changes to the lower threshold slow twitch fibers. The training program should be structured to produce the desired training effect.

Increases in strength are very specific to the type of exercise, even when the same muscle groups are used Figure 1. Specific motor units are recruited for specific tasks.

If a person is weight training to improve strength for another activity, the exercises should be as close as possible to desired movements. Likewise, when attempting to increase strength after an injury or surgery, rehabilitation should include muscle movements as close as possible to normal activities.

Figure 1: The importance of specificity during strength training. Subjects performed squats for 8 weeks and made impressive strength gains. On different exercises that used the same muscles, strength gains were much less.

Adapted from Sale 4. Muscle fiber type appears to play an important role in determining success in some sports. Successful distance runners have a high proportion of slow twitch muscles percent slow twitch fibers is highly related to maximum oxygen consumption.

Sprinters have a predominance of fast twitch muscles. Several studies have shown that a high content of fast twitch fibers is a prerequisite for success in progressive resistance training. This is understandable, as the fast twitch fibers experience selective hypertrophy as a result of high resistance, low repetition exercise.

However, all sports do not require prerequisite fiber characteristics. For example, in world class shot-putters there is a surprisingly diverse muscle fiber composition. In those athletes, larger muscle fibers rather than percent fiber type, accounted for their performance.

There are differences in the relative percentage of fast twitch fibers in explosive strength athletes. Having a high percentage of fast-twitch fibers is not necessary critical for success. Many strength athletes have a higher fast-to-slow twitch fiber area ratio than in sedentary subjects and endurance athletes.

Individual differences in training intensity and technique can make up for deficiencies in the relative percentage of fast twitch fibers in these athletes. It would be interesting to speculate about the performance of a shot-putter with a high percentage of fast twitch fibers.

What would performance be like in an athlete who developed good strength and technique? The high percentage of fast twitch fibers would probably be a decided advantage. Simultaneous participation in a training program designed to stimulate both strength and endurance has been found to interfere with gains in strength.

Strength athletes may inhibit their ability to gain strength by participating in vigorous endurance activities. Muscles may be unable to adapt optimally to both forms of exercise.

Muscles will atrophy as a result of disuse, immobilization, and starvation. In this context, I typically advise adopting a cautious approach. Balancing stress and recovery is a fundamental training principle that plays a crucial role in optimizing adaptations and ensuring long-term engagement in the sport.

A prevalent misstep I often encounter involves the inclination to arrange demanding endeavors—like races or extensive training sessions—in close proximity to the designated race day. An illustrative case arises when an athlete intends to participate in a mile race merely two weeks ahead of their target mile event.

However, the aftermath of the mile exertion might not yield its complete physiological benefits until a week or even more after the intended mile race. Consequently, rather than enhancing fitness, this mile race inadvertently adds to the burden of fatigue, leaving the athlete more tired than fit.

In this scenario, comprehending the progression of adaptations over time empowers the athlete, or coach, to strategically position their high-volume training sessions well in advance of the race day, guaranteeing complete adaptations and sufficient recovery.

In essence, understanding the time course of adaptations empowers endurance athletes, particularly trail and ultrarunners, to embark on a purposeful journey.

With insights into physiological changes that progress through early, intermediate, advanced, and long-term phases, athletes can fine-tune their training strategies for optimal performance.

This awareness not only ensures physical progression but also reinforces mental resilience. Through this synergy, athletes can navigate challenges, avoid common pitfalls, and run on a path that blends resilience, science, and commitment to achieve their fullest potential in the world of endurance running.

GAS helps us to understand how the body adapts to stressors and SAID helps us understand what specific movement or response we're asking the body to adapt to.

As fitness professionals, we can use the GAS model to our advantage to help our clients see results without suffering the negative consequences of exhaustion. When it comes to programming, GAS helps us understand why it's important to periodize, or systematically cycle through, different phases of training.

We plan our clients' workouts based on the physical adaptations, or outcomes, that they want to achieve. To help them achieve their goal, it's important to make a plan that will systematically help the client achieve the physical adaptations that they're seeking without stalling out staying in one phase for too long or burning out reaching exhaustion because of intolerable amounts of stress placed on the body.

Using the GAS model, we can expect a client to experience some fatigue, joint stiffness, or DOMS after the first couple of sessions while they're in the alarm stage. After a few weeks of consistent training, the symptoms of the alarm stage should lessen, and the client should enter the resistance development stage and begin to see improvements in their performance.

Their performance will continue to improve until their body adapts to what they're doing, and they possibly hit a plateau. Currently, or the end of 6 weeks in any given phase, it's time to move the client into the next phase of training, whether that means advancing to the next level or cycling back to an earlier phase to change the stimulus.

Cycling through the phases every weeks will allow your client enough time to recover from more difficult phases and to continue to see results as the stimulus continues to change. Keeping the GAS model and the SAID principle in mind while programming will help you better develop a fitness plan for your client that helps them reach their goal effectively and efficiently.
