Current UK guidelines for aerobic activity recommend that adults aged 19+ should spend at least 150 minutes (2 1/2 hours) per week in moderately intensive physical activity or 75 minutes per week of vigorous physical activity, or a combination of the two.
In addition to aerobic activity, the guidelines also recommend that adults should undertake muscle strengthening activities on at least two days per week to develop or maintain strength in the major muscle groups.
STATS: HOW ARE WE DOING?
The 2016 Health Survey for England reported that:
Only 26% of adults aged 19 and over meet both the aerobic and muscle strengthening guidelines.
This was higher for men (30%) than for women (23%)
These percentages have dropped from 34% (men) and 24% (women) reported in 2012.
The 2018 Physical Activity Guidelines for Americans echo these, with only around 20% of Americans meeting both the aerobic and resistance training minimums.
Furthermore, it seems that advancing age, increased BMI, and lower household income correlate with reduced participation in exercise.
WHERE CAN I START?
The UK Chief Medical Officers' PA Guidelines state:
Adults should aim to be physically active everyday.
Any activity is better than none, and more is better still.
There are no absolute thresholds: benefits are achieved at levels both below and above the guidelines.
In general, the more time spent being physically active, the greater the health benefits.
WHAT INTENSITY COUNTS?
Intensity can be gauged using the 'Talk Test':
"Moderate and vigorous activity can be differentiated by the ‘talk test’: being able to talk but not sing indicates moderate intensity activity, while having difficulty talking without pausing is a sign of vigorous activity."
WHAT ARE THE TYPES AGAIN?
AEROBIC ACTIVITY/ CARDIOVASCULAR TRAINING
Cardiovascular activity is defined as work that increases breathing rate and heart rate.
Health benefits can be seen from any intensity level of cardiovascular work however higher intensities require shorter durations to achieve the same benefits as lower intensities.
The guidelines recommend moderate-vigorous intensity exercise to achieve the most robust health benefit.
Moderate activity does include walking but it needs to be at a pace that presents a cardiovascular challenge such that the person could talk in sentences but not sing.
Steps accrued walking around the house or shopping are unlikely to constitute to this for healthy individuals but going for a brisk walk or hike may for some.
MUSCLE & BONE STRENGTHENING/ RESISTANCE TRAINING
Muscle strength and bone density contribute to physical function and overall health providing life long benefits.
Placed emphasis on working all of the major muscle groups and stimulating bone growth and repair.
Strengthening exercises have a substantial impact on maintenance of muscle mass and bone density into later life.
The balance training element they also provide paired with improved bone density and increased lean mass is strongly linked with reduced risk of falls and reduced severity of fall related complications.
Note that there is crossover between these two types. For example, running and ball games challenge the cardiovascular system but also increase bone density.
