0) Introduction: Hemoglobin concentration vs hemoglobin mass

1) Does hemoglobin mass increase with endurance training? - Training camp (Peaking and Tapering) - Training Season - Several years endurance training 2) Can hemoglobin mass be used as a «talent marker» for endurance sports? - Differences in hemoglobin mass between adolescent and elite athletes - Long term development in hemoglobin mass in adolescent athletes - Prediction of hemoglobin mass at elite age based on hemoglobin mass at age 16? Who did it? - Minimal hemoglobin mass neeed for elite endurance athletes?

3) Does hemoglobin mass increase with live high-train low (LHTL) altitude training? - „Hypoxic dose“? - „Individual response“? - Can hypoxic tents be used? - How long is hemoglobin mass increased after the altitude training?

4) Does a small increase in hemoglobin mass increase endurance performance? - Effect of low volume autologous blood doping on performance (increase like LHTL training)

5) Does LHTL increase endurance performance? What are important limiting factors?

6) A Swiss perspective – How do we support athletes and coaches?

6) Conclusions

Federal Office of Sport FOSPO 127 Swiss Federal Institute of Sport Magglingen SFISM Conclusion: Key Questions for elite endurance athletes, coaches and scientists

1) Does hemoglobin mass increase with endurance training?

- Training camp (Peaking and Tapering): No

- Training Season: No

- Several years endurance training: No

2) Can hemoglobin mass be used as a «talent marker» for endurance sports?

- Differences in hemoglobin mass between adolescent and elite athletes => Yes

- Long term development in hemoglobin mass in adolescent athletes =>Yes

- Prediction of hemoglobin mass at elite age based on hemoglobin mass at age 16? Who did it?

=> Those with already high hemoglobin mass at age 16

- Minimal hemoglobin mass neeed for elite endurance athletes?

=> 14g/kg males; 12g/kg females (national level)

=> 15-16g/kg males; 13-14g/kg females (world class level)

Federal Office of Sport FOSPO 128 Swiss Federal Institute of Sport Magglingen SFISM Conclusion: Key Questions for elite endurance athletes, coaches and scientists

3) Does hemoglobin mass increase with altitude training (LHTL)?

- „Hypoxic dose“? 400hours at 2500m

- „Individual response“? Yes, the increase ranges between 0% and 10%

- Can hypoxic tents be used? Yes, similar response in hemoglobin mass increase

- How long is hemoglobin mass increased after the altitude training? 4 (- 6) weeks

4) Does a small increase in hemoglobin mass increase endurance performance?

- Effect of low volume autologous blood doping on performance

Yes, a small amount of hemoglobin mass (like we reach with altitude training (5%)) increases endurance performance (time trial)

Federal Office of Sport FOSPO 129 Swiss Federal Institute of Sport Magglingen SFISM Conclusion: Key Questions for elite endurance athletes, coaches and scientists

5) Does LHLT altitude training increase endurance performance?

We think yes, scientifically it is very hard to prove (but also, that it does not work). Most studies showed increased performance.

Elite sport does not need the perfect study, due to individual different adaptations, every athlete has to try him-/herself

(For competitions at altitude, you have to prepare with altitude (Olympics Beijing 2022)

6) A Swiss perspective – How do we support athletes and coaches?

Since 15years, we support Swiss national team endurance athletes mostly on an individual base

However, it is not a magical tool, it is all about hard work.
