Relative Energy Deficiency in Sport (RED-S)

Relative Energy Deficiency in Sport (RED-S) is a condition characterized by insufficient energy intake relative to the energy expended by an athlete, affecting their overall health and performance. RED-S impacts sports performance, affecting both physical capabilities and mental well-being. Here is a list of the primary effects:

Physical Performance:

1. Chronic Fatigue: Persistent tiredness reduces overall energy levels and stamina.
2. Reduced Endurance: Lower ability to sustain prolonged physical activity.
3. Decreased Strength: Diminished muscle power affects performance in strength-dependent sports.
4. Impaired Coordination: Reduced motor skills and precision, leading to technical errors.
5. Slower Reaction Times: Delayed responses can impair performance in fast-paced sports.
6. Increased Injury Risk: Higher likelihood of stress fractures, bone injuries, and muscle strains.
7. Slower Recovery: Prolonged recovery times after training sessions and competitions.
8. Frequent Illnesses: Weakened immune system leads to more frequent infections and illnesses.

Psychological Effects:

1. Increased Stress and Anxiety: Heightened mental strain can impact focus and motivation.
2. Depression: Negative impact on mood and overall mental health.
3. Reduced Concentration: Difficulty maintaining focus during training and competitions.
4. Poor Decision-Making: Impaired cognitive function can lead to strategic and tactical errors.
5. Decreased Motivation: Reduced drive to train and compete.

Overall Athletic Impact:

1. Inconsistent Performance: Fluctuating energy levels and mental state lead to variable performance outcomes.
2. Decreased Competitive Edge: Overall decline in performance reduces competitiveness.
3. Longer Recovery Periods: Extended time needed to return to peak performance after training or injury.
