Training design improves safety, efficiency, and performance

1. Training principles are fundamental rules that guide the design and execution of exercise programmes.
2. They ensure that the programme is efficient, safe, and tailored to the athlete's goals. This helps improve health and performance.

Training stress sits on a continuum between undertraining and overtraining

1. Training stress and the body's response sit on a continuum, from undertraining (where the stimulus is too small to drive adaptation) to overtraining (where stress exceeds what the body can tolerate).
2. Between them lies a zone of optimal performance enhancement, and the line between optimal and excessive is narrow.

Overreaching

1. Overreaching is when an athlete deliberately pushes their body beyond its current limit of tolerance for a short period to stimulate a training response.
2. Functional overreaching is when performance returns to normal within days to a few weeks, and can be a useful training tool when followed by recovery.
3. Non-functional overreaching is when recovery takes weeks to months instead, performance declines, and psychological and hormonal disturbances appear.

Training principles that shape safe and effective programmes

1. Specificity

1. Specificity means that exercise adaptations are specific to the type of activity being performed (e.g., training for long-distance running will primarily improve cardiovascular endurance).
2. The training should match the demands of the sport, which ensures that the right physiological adaptations occur.

2. Progressive Overload

1. Progressive overload is the principle that stresses the importance of gradually increasing the intensity, volume, or duration of exercise to continue making gains in performance.

Progressive overload is adjusted through frequency, intensity, and duration

1. Frequency: How often training occurs (e.g., training 3 times a week versus 5).
2. Intensity: The level of difficulty (e.g., increasing weight lifted or running at a faster pace).
3. Duration: The length of the training session (e.g., increasing the length of a run or workout).

3. Recovery (Rest Principle)

1. Recovery is crucial to prevent overtraining and to allow the body to adapt to the stress caused by exercise.
2. This is where strength, endurance, and other performance aspects improve.

Recovery includes rest and active recovery

1. Rest: Complete rest or low-intensity activities that allow the body to repair (e.g., taking a day off from exercise or doing light walking).
2. Active Recovery: Low-intensity exercise following a more intense workout, such as swimming or cycling at an easy pace. Active recovery enhances circulation and helps clear metabolic waste products from the body, promoting faster recovery.

4. Variety

1. Variety involves changing aspects of the training programme to prevent boredom, reduce the risk of injury, and stimulate different muscle groups.

5. Reversibility

1. The principle of reversibility states that any gains made from training will be lost if training is reduced or stopped altogether.
2. Detraining begins quickly after training stops, and some adaptations (such as aerobic capacity) decline faster than others (such as maximal strength).

6. Periodization

1. Periodization is the systematic planning of athletic training to maximize performance while minimizing the risk of injury.
2. It involves dividing the training plan into distinct phases, each with specific goals and training intensity.
3. The goal of periodization is to peak at the right time, such as during competition, while maintaining overall progression.

Periodization is organised into macrocycles, mesocycles, and microcycles

1. Macrocycle: The longest period, typically lasting a year or more. It includes all training phases and recovery periods.
2. Mesocycle: A smaller training cycle within the macrocycle, usually lasting 3-4 weeks and made up of several microcycles, focused on specific training goals (e.g., strength or endurance).
3. Microcycle: The smallest training cycle, lasting a week. It involves detailed daily or weekly adjustments to volume, intensity, and rest.

Periodization splits the macrocycle into three phases

Periodization typically splits the macrocycle into three cyclical phases: transition (post-season), preparation (pre-season), and competition.

Transition (post-season)

1. The transition phase allows the athlete to recover and refresh after the competitive season, typically lasting 3 to 4 weeks.
2. Active rest in different environments and activities is preferred over complete rest, which can lead to detraining.

Preparation (pre-season)

1. The preparation phase prepares the athlete physically, psychologically, technically, and tactically for the competition phase, typically lasting 3 to 6 months.
2. The general preparatory sub-phase focuses on building basic fitness and physical conditioning.
3. The specific preparatory sub-phase shifts the focus toward sport-specific training and may include low-stakes competitions to test readiness.

Competition

1. The competition phase runs through the competitive season, with training volume reduced and the focus on maintaining fitness, sharpening sport-specific skills, and gaining competition experience.

Baseline values and progress tracking guide programme decisions

1. Baseline values give a reference point for the individual's current fitness level at the start of a programme.
2. A needs analysis identifies the demands of the sport and the gaps in the athlete, helping the coach design an appropriate programme.
3. Tracking progress through regular retesting (often at the end of each mesocycle) allows the coach to monitor improvement and adjust intensity and volume.
4. Baseline and progress data also help identify potential injury risks and signal when more rest or recovery is needed.

Training load is measured by external and internal indicators

1. External load indicators describe what the athlete does, including distance covered, power output, number of repetitions, and weight lifted.
2. Internal load indicators describe how the body responds, including oxygen uptake, heart rate, blood lactate, and rate of perceived exertion (RPE).
3. Resistance training intensity is often prescribed as a percentage of one repetition maximum (1RM), the heaviest weight that can be lifted once.

Adaptive response depends on the training method

1. Aerobic methods such as endurance running, cycling, and swimming drive central adaptations like increased stroke volume and blood volume, and peripheral adaptations like more mitochondria and capillaries.
2. Anaerobic methods such as sprinting, plyometrics, and heavy resistance training drive adaptations in the phosphagen and glycolytic systems, and in muscle fibre recruitment and strength.
3. Inter-individual differences, such as genetic differences between responders and non-responders, also influence how an athlete adapts
