- The purpose of this paper is to explore research opportunities in the Olympic sport of rowing. While innovation in equipment is promoted in rowing the FISA rules don’t allow for it to be a deciding factor in the performance outcome for an individual crew. Thus, the challenge is to look at innovative ways to develop these abilities within a boat and harness their energy to create the most efficient and effective machine. This paper describes an outlook identifying four areas containing research opportunities with an emphasis on being able to ‘fine tune’ the moving parts of the engine that is a rowing crew: Sonification in the learning of motoric movement, rowing dynamics that will impact the hydrodynamics around the hull by inducing pitch and heave instead of forward propulsion, surface structures and finally objectivity in on water performance. A research outlook is made into different research opportunities in Rowing, using a coaches perspective. Another novelty is the comparison of the work carried out by the athletes in the rowing to the situation in production systems with assembly operators working at assembly workstations, opening up an new area of well-established theories to by utilised in sports.

- Previous swim start studies involving electromyography (EMG) consistently comprised unilateral measurements and the attachment of the swimmer via cables to a computer. Therefore the present work aims for an overall picture of the muscle activation pattern during the swim start by conducting bilateral measurements with minimal restriction of motion. On that account a multichannel surface EMG device with a wireless Bluetooth connection and videography is utilized in order to assess the nowadays most common start dive techniques of competitive swimming events - differently weighted track starts from the OMEGA OSB11 starting block. The data analysis identified that the normalized muscle activation levels were higher during the front-weighted than during the rear-weighted start - probably caused by shorter block times and less contribution of the arms. Furthermore the onset of the muscle activation seems to be different in between start dive techniques, as for instance the muscles of the rear leg commence contracting earlier while the muscles of the front leg start later in the rear-weighted compared to front-weighted starts. It is highly likely that this originates in the position of the center of mass relative to the muscles. A general overview over the coordination of the different muscles could also be obtained: It became obvious that some muscles are the main drivers of the swim start (vastus lateralis, soleus) whereas others rather exerted supportive actions (gluteus maximus, semitendinosus, erector spinae longissimus).
