Tubing targets the same muscles, but because of the ease of varying the resistance by simply stretching or slackening the exercise tubing, this variation may be better than the dumbbell variation for an on-deck dryland program.




Lateral Dumbbell Deltoid Raise




Execution


1. Stand and hold a dumbbell in each hand with your arms hanging at your sides and your palms facing your thighs.

2. With a slight bend in your elbows, raise the dumbbells to the side until they are level with your shoulders.

3. Slowly lower the dumbbells.


Muscles Involved

Primary:Middle deltoid

Secondary:Anterior deltoid, posterior deltoid, supraspinatus, trapezius


Swimming Focus

The primary focus of this exercise is the middle deltoid, one of the key muscles involved in the recovery phase of freestyle and butterfly. Unlike freestyle, butterfly lacks a body roll to aid in arm recovery, leading to heavy reliance on the deltoid muscle group, particularly the middle deltoid, to reposition the arm. As with the forward dumbbell deltoid raise, you should emphasize a tall, upright posture when performing this exercise. Like the forward dumbbell deltoid raise, this exercise is a good fundamental starting point for you to practice setting your scapula when performing upper-extremity exercises.



SAFETY TIP

To avoid overstressing the rotator cuff muscles, which are stabilizing the shoulder joint during the exercise, do not raise the dumbbells above shoulder height.


VARIATIONS

Lateral Deltoid Raise With Tubing

Tubing targets the same muscles, but because of the ease of varying the resistance by simply stretching or slackening the exercise tubing, this variation may be better than the dumbbell variation for an on-deck dryland program.

Overhead C

As mentioned previously, raising the arms above the level of the shoulders while the palms are facing down can be detrimental. The addition of the C at the end range changes the position of the shoulders in a way that allows movement of the arms above shoulder height while alleviating the concern of causing excessive stress to the rotator cuff. To complete the C movement, envision each hand as the hand of a clock. Starting in the 6 o’clock position with your palms facing down, rotate both upward in a clockwise manner to the 12 o’clock position.




T Exercise




Execution


1. With a dumbbell in each hand, raise your hands forward until the dumbbells are level with your shoulders.

2. Return to the starting position and then raise the dumbbells laterally, again until they are level with your shoulders.

3. Return to the starting position and then lift the dumbbells back behind your torso at approximately 45 degrees.

4. Start again with the forward raise.


Muscles Involved

Primary:Anterior deltoid, middle deltoid, posterior deltoid

Secondary:Supraspinatus, trapezius


Swimming Focus

This exercise targets all three portions of the deltoid (anterior, middle, and posterior), making it an excellent all-around exercise for strengthening the shoulders. As a result, it strengthens the recovery phase of all four strokes. For the younger swimmer first entering the sport, this is a good exercise for the initial development of shoulder strength, which will be important as the swimmer progresses and increases yardage gradually. For the older swimmer, because of the multiple movements targeted, this exercise is better suited for building endurance at the beginning of the season or when recovering from an injury.




Dumbbell Shoulder Press




Execution


1. Sitting up straight, hold the dumbbells at shoulder level with your elbows in and your palms facing your body.

2. Press the dumbbells upward until your elbows are almost locked.

3. Slowly lower to the starting position.


Muscles Involved

Primary:Anterior deltoid, middle deltoid

Secondary:Pectoralis major, posterior deltoid, trapezius, supraspinatus, triceps brachii


Swimming Focus

To maximize the distanced gained during each stroke, you need to be able to enter the water with your arm or arms extended and your body in an elongated position. This exercise helps develop overhead strength and confidence in extending your reach when entering the water.

The exercise described here is a modified version of the military press motion performed in traditional weight lifting. The traditional version is usually performed with the dumbbells held in the “stick ’em up” position, with the palms rotated outward. Swimmer should avoid this position because it can place undue stress on the shoulders and could be detrimental when combined with the stress already present from the yardage load in the water.

Обручев Сергей Владимирович (1891-1965 гг.) известный советский геолог и географ, член-корр. АН СССР. Высоко образованный человек - владел 10 иностранными языками. Сын академика В.А.Обручева, . будущий исследователь Азии, Сибири, Якутии, Арктики, родился в г. Иркутске, получил геологическое образование в Московском университете, закончив который в 1915 г., после недолгой работы на кафедре оказался в Геологическом комитете и был командирован для изучения геологии в Сибирь, на р. Ангара в ее среднем течении. Здесь он провел несколько полевых сезонов. Наиболее известны его экспедиции на Северо-Восток СССР. Совершил одно из значительных географических открытий в северо-восточной Азии - системы хр. Черского - водораздельной части Яно-Индигирского междуречья. На северо-востоке Якутии в Оймяконе им был установлен Полюс холода северного полушария На Среднесибирском плоскогорье - открыт один из крупнейших в мире - Тунгусский угольный бассейн. С.В. Обручев был организатором и руководителем более 40 экспедиций в неосвоенных и трудно доступных территориях России. С 1939 на протяжении более 15 лет его полевые работы были связаны с Прибайкальем и Саяно-Тувинским нагорьем. В честь С.В.Обручева названы горы на Северо-востоке страны, полуостров и мыс на Новой Земле.
