Safe Practice in Dance Many causes of injury and illness in dance are due to: mistakes in training over-worked hard floors cold rooms repetition in rehearsal touring conditions psychological stress ‘ many teachers lack anatomical, physiological knowledge’ . Peter Brinson, Healthier Dancer Conference. Teachers should know more about exercise physiology: teach students how the body works, injury prevention and how to treat injuries properly. Most dancers do not follow up the care of injuries and continue to dance instead of resting. Injuries should be regarded as a signal that something is wrong, a lesson to be learned, too many times injuries are never identified. Very few dancers are familiar with the vital ‘RICE’ formula. Dancers should be more aware that injuries can result from their lifestyle and attitudes to class or rehearsal. Students should wear suitable clothing in class which allows the teacher to see the body. Self discipline is vital in dance, going to dance classes regularly will aid personal growth, security, respect and self confidence. It should be accepted that dancers ask questions to their choreographers and teachers on what they require. More recently dance companies are being made aware of the importance of nutrition, exercise, physiology and anatomy. However there is still little collaboration between the dance and medical profession except in big schools such as London Contemporary Dance School, Rambert Dance School and the Laban Centre for Movement and Dance. Dance students and professionals are emotionally vulnerable because they usually begin their training before their personalities are fully formed: they succumb easily to pressures. Nutrition - dancers eating habits are extremely bad, even though they know it is wrong to skip meals, snack on chocolate and smoke. Unfortunately they also give each other unreliable advice about diets and do not know where to seek advice and treatment. An increased number of dancers suffer from anorexia or other eating disorders. In an ideal world, dancers should receive regular health counselling and be given a personal health record sheet ( the same support that is available for athletes ) . Dancers should try maintain proper eating habits and knowledge about the kind of nutrition dancers need for maximum energy. ‘ Choreographers demand too much of dancers’ bodies, often repeating difficult movement in too long rehearsals ‘. (Healthier Dancer Conference, Peter Brinson ) Dancers who train in aerobic fitness will increase the blood supply and oxygen to their muscles: ‘ fluid replacement is vital during exercise, dancers are advised to sip water during performances and rehearsals’. (Healthier Dancer Conference, Jann Parry ) Effects of training young dancers (warm ups) ‘ It is essential that students are taught about the importance of a warm up before beginning their classes. The class itself is not the warm up prior to the day’s work. Warm up means that the muscles must be worked gently and thoroughly in order to increase the blood supply and this will then increase the flexibility and smoothness of the contraction of the muscles. It is essential that any dance leader should have a good knowledge of how the body works both anatomically and physiologically ‘ ( Summary of a lecture given at the Dance Medicine Conference in Guildford on May 30, 1992 ( Dancing Times, Oct.1992 ) Training as a Dancer… A dancer requires many attributes before becoming a successful performer. A dancer in training requires a progressive build up of technical ability within in a well designed programme of training. What is essential for safe technique ? Muscular strength - enables dancer to move with assurance, manage technical demands of the dance Stamina - ability to keep going, sustained performance. As the muscle groups are developed so must the heart and lungs be prepared for exercise. The heart develops through use. Raising the heart rate, increases the blood flow around the body and subsequently the efficiency of muscles. What should a training program offer ? There are 4 principles which apply to all fitness training. They are: 1) Specificity - training must be specific to the activity, the type of fitness required and which particular muscle groups you need to work. 2) Overload - training must be raised to a higher level than is normal to create the extra demands to which the body will adapt. This can be done in three ways: - Frequency - 3 times a week ( no. of classes ) - Intensity ( how physically demanding or difficult it is e.g. distance covered in running, lengthen in jumps, decrease less rests, add weight (foot,arm) - Duration of time ( how long the training sessions last ) 3) Progression - as the body adapts to training it progresses to a new level of fitness. Progress to the next level is achieved by a gradual increase in intensity to create an overload. 4) Reversibility - Training effects are reversible. If exercise is reduced in intensity or stopped altogether then the benefit can be quickly lost. Deterioration sets in after about one week. Strength and speed are gradually lost with muscles losing their tone and size. opportunity for regular and sustained use of the cardiac muscle ( this repetitive use will encourage the heart to work effectively ) general class activity will involve aerobic and anaerobic systems ( cardiovascular fitness ) a dancer strives for increased strength and co-ordination by perfecting class exercises and improving technique. .Co-ordination ( neuro-muscular fitness ) is developed through persistent training and practice. Repetition in an exercise programme (which uses all the motor skills ) can stimulate the brain to organise the correct response for the appropriate movement.This happens as a result of familiarisation via technique and the repetition with good feedback from the teacher/choreographer allows the student to make the corrections and the brain learns which response to make. The technique needs to offer all areas of motor skills such as: balance, agility, speed , power and reaction time for optimum results. NB Repetition by itself may achieve nothing. It is only useful if it accompanied by feedback so that subsequent repetitions can be improved until the motor skill can be performed time after time with accuracy. Such technical ability when refined to this degree releases the dancer from concentrating on the activity as a physical act, and allows him/her to involve interpretative and emotional responses for a more complete performance. A programme of classes should include: variation in movement patterns, interesting footwork, changes in direction, additional arm movements, changes of level and pace. * Flexibility: - good for dancers as it increases motion - audiences and choreographers like to see flexibility reasonable flexibility decreases the risk of injuries Factors dictating flexibility type of joint i.e. shoulders are more flexible than the elbows ligaments, tendons are elastic where joined to others quality and texture of connective tissue within the muscles fat deposits - skin thickness and tightness. Stretching techniques: static stretches e.g. holding positions for a maximum length (30sec-1min) go into gently, do not snap, if you do it quickly the muscle tightens bouncing - this is bad, a quick stretch increases muscle tension and soreness leads to muscle tears The best formula is = Propriaceptive neuromuscular facilitation. This method uses contraction and relaxation of the muscles 3 times ending with a static stretch. Other attributes which are important to the dancer’s training include spatial and rhythmic clarity: Spatial clarity: awareness /understanding of the dance/performance space/other dancers. It is developed as part of the dance class. The warm up will include work on the floor, standing and moving between. The dancer becomes aware of levels and her own personal space. The teacher demands accuracy in the execution of the exercises. The three senses: hearing, sight and touch, are extremely important in guiding a dancer's movement with proper appreciation for: distance, space and balance A combination of these senses allows movement to be performed in a controlled, smooth, co-ordinated manner. Rhythmic clarity: achieved by an understanding of the accompaniment. Step patterns and movements can vary in complexity. Summary All round training should include strength and flexibility exercises. ‘ Training the body involves a systematic use of repetitive and progressive exercises to stress the muscular skeletal, respiratory, cardiovascular and nervous system. The goal is to inharness the various components on various fitness, or conditioning including strength,flexibility, neuromuscular co-ordination, and cardiovascular respiratory function such that a given movement can be performed repeatedly, efficiently with optimal and without indue fatigue ‘. ( From K. Clippinger - Robertson, Science of Dance Training 1988 ) Training hopes to achieve: 1. Aerobic and anaerobic fitness 2. Appropriate muscle development and flexibility 3. Neuromuscular co-ordination
