Aerobic Activity
What counts as vigorous-intensity aerobic activity?
Examples of activities that require vigorous effort for most people include:

•jogging or running
•aerobics
•swimming fast
•riding a bike fast or on hills
•playing singles tennis
•playing football
•hiking uphill
•energetic dancing
•martial arts
Vigorous-intensity aerobic activity means you're breathing hard and fast, and your heart rate has gone up quite a bit. If you're working at this level, you won't be able to say more than a few words without pausing for a breath.

In general, 75 minutes of vigorous-intensity activity can give similar health benefits to 150 minutes of moderate-intensity activity.

What counts as muscle-strengthening activity?
Muscle-strengthening exercises are counted in repetitions and sets. A repetition is one complete movement of an activity, like lifting a weight or doing a sit-up. A set is a group of repetitions.

For each activity, try to do 8 to 12 repetitions in each set. Try to do at least 1 set of each muscle-strengthening activity. You'll get even more benefits if you do 2 or 3 sets.

Preventing falls
Older adults at risk of falls, such as people with weak legs, poor balance and some medical conditions, should do exercises to improve balance and co-ordination on at least two days a week. These could include yoga, tai chi and dancing.

To gain health benefits from muscle-strengthening activities, you should do them to the point where you find it hard to complete another repetition.

There are many ways you can strengthen your muscles, whether at home or in the gym. Examples of muscle-strengthening activities include:

•carrying or moving heavy loads such as groceries
•activities that involve stepping and jumping such as dancing
•heavy gardening, such as digging or shovelling
•exercises that use your body weight for resistance, such as push-ups or sit-ups
•yoga
•lifting weights
You can do activities that strengthen

    An acute response of the musculoskeletal system during exercise includes an increase in blood supply. The short term effects on your muscles increases the temperature therefore there is more activation energy so chemical reactions are used by the musculoskeletal system and the metabolic activity increases. As the oxygen demand increases, more oxygenated blood needs to be supplied to the muscles so vasodilatation occurs so more blood can pass through the arteries. This affected me during the bleep test because vasodilation allows more oxygenated blood to travel to the actively respiring muscle tissues.…

    To develop strong abdominal, back and hip muscles, you need to perform core strength workouts. While these muscles are fairly large compared to the other muscles in your body, they still need time to rest and recover so they grow strong. Thus, you should do core strength exercises no more than three times a week on alternate days. Also, if you are performing bodyweight exercises for core strength, strive to do twenty repetitions. If you have added weights to your routine, strive only for 15 repetitions.…

    The main aim of the practical was to assess, what affects did light exercise have on the systolic and diastolic blood pressure, heart and respiration rate, tidal volume, minute volume and percentage of gas. The readings were taken before exercise, during exercise and after exercise. Blood pressure is defined as the amount of pressure exerted on the vessels walls, during blood flow. Blood pressure can be measured using a sphygmomanometer. The upper value indicates the systolic pressure; this is the highest level of pressure obtained. This is usually 120mm Hg in healthy adult. The diastolic blood pressure is the pressure achieved before the aortic valves reopen, which is usually between 70- 80mm (Barbara, J.C. 2005). The heart rate is the number of beats that is pumped by the heart per minute. It’s measured by taking the pulse rate. Respiratory rate is the number of breath exhaled and inhaled in a single breath. Respiratory rate can be measured simply by observing the person’s chest and stomach rise and fall. It is usually measured in breath per minute. Tidal volume is the amount of air inhaled or exhaled in a single breath. In an average human, the tidal volume is about 0.5litres, while the lungs can hold up to ten times more than this. Minute volume, is the amount of air or fluid moved per minute.…

    Weight training is more than developing a sculpted body. Strong and healthy muscles are important for all activities performed throughout the day. Weight training helps with mundane tasks such as housecleaning, mowing the lawn and shoveling snow. It also aids in the body’s efficient use of oxygen, placing less strain on the heart. Good posture is the result of strong muscles being able to support the rest of the body’s mass 24 hours a day. In addition, weight training is useful in injury rehabilitation, thus returning people to pain-free activity. Weight training increases power, speed, muscular endurance, and flexibility for many types of activities.…

    Gym Set Vs Single Set

    Therefore, it will be wise to use single set exercises for quite a number of different reasons. For example, I will use single over multiple sets during an off season and coming back from an injury. It will not make sense for me to destroy my body after a full season of sports. Body needs rest and eight hours a day just is not enough at a higher level. In addition, if the athlete is rehabilitating from a recent injury, single sets will be the better choice to progress to his or her normal weight range. If the person is not an athlete and never been to a gym or lifted a dumbbell; then single set exercises will be a great introduction to learn the fundamentals and gain the confidence to work out. Another example, Person A does 1 set of 5 repetitions with 5 different exercises with max load. Person B does 5 sets of 10 reputations with 5 different exercises with 70-80% load. Who will gain more strength over a longer period of time? The answer is not important because it implies both are achieving the same amount of results over a period of time. Therefore, I believe both single and multiple sets are useful based on the training plan and…
