Benefit: The flutter kick works the hip flexors. Because it is a small move, it does not get the heart rate up as much as a larger move, even when you flutter kick fast, but the core muscles must tighten to stabilise the body and maintain the upright position.
Common mistakes: Flutter kicking from the knees instead of the hips. Fast kicking from the knees is hard on the knee joints.
Benefit: The kick forward uses the quadriceps and hip flexors.
Common mistakes: 1. Performing the kick in a seated position instead of returning the hips to the fully extended position; 2. Power popping the knees; that is, adding force at the end of the kick, which is hard on the knee joint.
Benefit: The high kick increases the range of motion, therefore increasing intensity.
Common mistakes: 1. Leaning backward to get the toes out of the water, which takes the spine out of neutral alignment; 2. Emphasising the upward motion at the expense of the downward motion, which works the powerful hip flexors more than the weaker gluteus maximus.
Benefit: The Cossack kick is used in place of the kick side-to-side, which is used only in shallow water. The kick side-to-side requires a weight shift, which is not possible in deep water. If the exercise is attempted, the lower back is stressed. The Cossack kick works the trapezius, quadriceps and hamstrings. To perform the exercise, the core is stabilised, the shoulder blades are contracted, and the hips are open in a diamond position; the arms then reach to the sides at the same time as the legs kick to the sides.
Benefit: The kick backward works the gluteus maximus.
Common mistakes: 1. Bending the knee, which takes the work out of the gluteus maximus and puts it in the hamstrings; 2. Arching the back, which puts stress on the lower back. To avoid arching the back, lean forward slightly from the hips.
2. Cross-country ski
Benefit: This exercise works the hip flexors and gluteus maximus, as well as the shoulders. It is a long-lever, high-intensity move, which burns calories.
Common mistakes: 1. You want full hip flexion and hyperextension, but many people limit the range of motion to forward flexion, the same as a kick forward, especially when travelling backward; 2. The arm movement contributes to the intensity, but some people reduce it by pushing the hands forward instead of swinging the arms through their full range of motion.
3. Jumping Jacks
Benefit: Jacks work the adductors and gluteus medius. The arms and legs work opposite in deep water to avoid bobbing and possibly submerging the head.
Common mistakes: 1. Trying to make the legs go too far apart, which is hard on the hip joints; 2. Bending the knee when travelling sideways, which is the same as a Cossack kick, which works the quads and hamstrings instead of the hip adductors; 3. Pointing the toes out, which works the hip flexors instead of the gluteus medius.
You can create many variations of these exercises. Here are some examples:
- Try different arm movements – such as standing row, arm swing, lat pull-down, clap hands, arm curl, and forearm press. Use alternating arms or both arms in unison. If you use one arm or no arms, you will challenge your core muscles, because maintaining neutral posture will be harder.
- Vary the tempo – the speed at which exercises are performed in deep water is slower than in shallow water because the range of motion is greater, but you can still vary the tempo with pauses (3\x\ and hold) or syncopate (slow, slow, quick, quick, quick).
- Change the working position – exercises can be performed upright, at a diagonal angle, side lying, or seated.
- Add turns – you can do quarter turns, half turns or full turns. Diagonal turns are quarter turns toward the right corner and then toward the left corner.
- Combine exercises – putting two or more exercises together creates a new exercise.
Not every variation will work with every exercise, but using even a few variations will increase the number of exercises in your repertoire. Exercisers are able to judge how hard they are working by using perceived exertion. One scale of perceived exertion (see Table 5.3) uses numbers from one to 10. Each number corresponds to a percentage of maximum exertion.
The target heart rate for aerobic exercise is 50-80% of the maximum heart rate. Participants who are working somewhat easy (50%), with moderate effort (60%), somewhat hard (70%), and hard (80%) are working within their target heart rate. During the pre-season, you will ask your participants to work at a minimum of 50% of their maximum exertion during the continuous cardiorespiratory training sessions.
