Final answer:
Vibration is not the best choice for sports inter-competition massage as it can be stimulating rather than relaxing and may cause muscle fatigue.
Step-by-step explanation:
The technique that is not the best choice for sports inter-competition massage is D. Vibration. Vibration is a technique that involves shaking or vibrating movements, which may cause muscle fatigue and disrupt athletic performance. While other techniques like effleurage, tapotement, and compression are commonly used in sports massage to promote muscle relaxation, improve blood circulation, and reduce muscle soreness, vibration may not be suitable during inter-competition as it can be stimulating rather than relaxing.
