HIIT (High Intensity Interval Training)

 HIIT (High Intensity Interval Training) is an aerobic exercise that replaces short periods of intense anaerobic exercise with less intense recovery periods. The main aspects of HIIT are described here:

• Benefits:
• Efficient exercise: Although HIIT training is usually shorter in terms of training duration, it can be as effective as, or even more effective than, a long steady-state aerobic exercise session.
• Increased metabolic rate: HIIT can boost metabolism for several hours after exercise.
• Improved cardiovascular health: Regular HIIT improves heart health, blood pressure and cardiovascular function.
• Muscle preservation: HIIT helps preserve muscle mass while promoting fat loss.
• Versatility: HIIT can be combined with a variety of other exercises such as running, cycling and bodyweight exercises.

Basic structure:

• Warm-up:  Begin with a 5-10 minute warm-up to prepare the body.
• Intervals: alternate high-intensity exercises (e.g. sprints, jumping jacks, burpees) with low-intensity recovery time or rest.
• High intensity: 20-60 seconds of maximal effort.
• Low intensity: 10-60 seconds of active or complete rest.
• Cool down: 5-10 minutes of cool down and stretching to finish.

Examples of HIIT workouts

• Warm-up: 5 minutes jogging or brisk walking. 
• Intervals:

1. Sprint 30 sec.
2. 30 seconds walking.
3. Repeat for 10 rounds.

• Cool down: 5 minutes of light jogging or walking, followed by stretching.

HIIT tips

• Start slowly: If you are new to HIIT, start with short intervals and gradually increase intensity and duration.
• Start with form: To avoid injury, use correct form, especially for high-intensity exercises.
• Rest and recovery: Allow your body to recover between HIIT sessions to avoid overtraining.
• Listen to your body: Adjust the intensity and duration according to your fitness level and your body's response.

Variations:

• Tabata: 20 seconds of exercise followed by 10 seconds of rest for 4 minutes.
• Circuit training: Combine different exercises in a circuit format with minimal rest between exercises.
• Pyramid intervals: lengthen or shorten the duration of the intervals (e.g. 30, 45, 60, 45, 30 seconds).

HIIT is an adaptable and effective method of exercise as it can be customized to suit individual fitness levels and preferences.

High intensity exercise and hot flashes

High- Intensity Exercise and Hot Flashes Recent research has shed light on the relationship between high- intensity exercise and hot flashes, particularly in women experiencing menopause. Here are some crucial points from current findings  

Key Findings:

1. Triggering Hot Flashes: 

• High- Intensity Exercise: Intense physical activity can increase core body temperature, which might trigger hot flashes in some women. This occurs because the body’s attempt to cool down during and after violent exercise can mimic the physiological changes that cause hot flashes.
• Physiological Stress: High- intensity workouts can cause significant physiological stress, which may complicate the frequency and severity of hot flashes in some individuals. 

2. Alternative Exercise Recommendations:

• Low- Intensity Activities: Switching to lower- intensity exercises, similar as walking, swimming, yoga, or pilates, may help reduce the frequency and intensity of hot flashes. These activities are less likely to cause a significant rise in core body temperature.
• Moderate Exercise: Engaging in moderate exercise like brisk walking, cycling, or light aerobics can still offer cardiovascular and overall health benefits without the same level of threat for triggering hot flashes.

3. Exercise Benefits:

• Overall Health: Despite the potential for high- intensity exercise to trigger hot flashes, regular physical exertion remains crucial for overall health. It can improve cardiovascular health, maintain muscle mass, reduce stress, and promote internal well- being. 
• Symptom Management: Regular, moderate exercise can help manage other menopausal symptoms, such as mood swings, sleep disturbances, and weight gain. 

Recommendations for Women passing Hot Flashes:

• Monitor Symptoms: Keep a log of exercise activities and hot flash occurrences to identify potential triggers.
• Hydration: Ensure acceptable hydration before, during, and after exercise to help regulate body temperature. 
• Cooling Strategies: Use cooling towels, fans, or air- conditioned environments during exercises to help manage body temperature. 
• Clothing: Wear lightweight, moisture- wicking clothing to stay cool during exercise. 
• Consult Healthcare Providers: Discuss exercise plans with a healthcare provider, especially if experiencing severe hot flashes or other menopausal symptoms. 

Conclusion:

• While high- intensity exercise can potentially trigger hot flashes in some women, modifying exercise routines to include lower- intensity activities can help manage these symptoms while maintaining overall health benefits. It’s essential to listen to your body and adjust exercise intensity based on particular comfort and health needs.
