How to Maintain Muscle Mass During a Long Sports Season

Many athletes start the season strong, fast, powerful, and resilient, only to feel weaker, flatter, and more fatigued as the season progresses. Performance may hold up temporarily, but muscle mass often declines quietly in the background.

This is one of the most common and overlooked issues in competitive sport. At Kalos, we use DEXA Scan body composition data to help athletes identify muscle loss early and adjust training, nutrition, and recovery before performance drops.

Here is how to maintain muscle mass during a long sports season and why most athletes unintentionally lose it.

Why Muscle Loss Happens During the Season

Muscle loss during a season is rarely caused by lack of effort. It usually comes from accumulated stress.

Common contributors include:

• High training and competition volume
• Reduced strength training time
• Inadequate calorie intake
• Insufficient protein
• Poor sleep and travel stress
• Incomplete recovery between games

Over time, the body prioritises survival and endurance over muscle maintenance.

Why Muscle Loss Hurts Performance

Even small losses of muscle mass can significantly affect performance.

Consequences include:

• Reduced power output
• Slower sprint speed
• Lower jump height
• Poorer change of direction
• Increased injury risk
• Slower recovery

DEXA scans often reveal muscle loss weeks before athletes feel a noticeable drop in performance.

The Mistake of Prioritising Conditioning Only

During the season, many athletes replace strength training with conditioning and sport specific work.

While conditioning is important, removing strength work entirely leads to:

• Loss of muscle stimulus
• Reduced force production
• Declining strength to weight ratio

Strength training volume may decrease in season, but it should never disappear.

How Much Strength Training Is Enough In Season?

Maintaining muscle requires far less volume than building it.

For most athletes:

• 1 to 2 well structured strength sessions per week is sufficient
• Focus on compound movements
• Keep intensity relatively high
• Reduce volume, not load

This sends a clear signal to maintain muscle without excessive fatigue.

Protein Intake Is Non Negotiable

Protein requirements often increase during a long season due to higher physical stress.

Insufficient protein leads to:

• Increased muscle breakdown
• Slower recovery
• Higher injury risk

Many athletes unintentionally under eat protein during travel or congested schedules. DEXA scans frequently show muscle loss even when body weight remains stable.

Energy Availability Matters More Than Leanness

Trying to stay lean throughout a long season often backfires.

Low energy availability leads to:

• Hormonal disruption
• Poor recovery
• Muscle loss
• Increased illness risk

Maintaining muscle requires adequate calories to support training and competition demands.

Recovery Is a Muscle Preservation Tool

Recovery is not optional during a long season.

Key recovery factors include:

• Sleep consistency
• Rest days or low load sessions
• Stress management
• Strategic deloads

When recovery is insufficient, the body sacrifices muscle to cope with ongoing stress.

Why Travel and Scheduling Increase Muscle Loss Risk

Long seasons often include travel, irregular meals, and disrupted sleep.

These factors:

• Increase cortisol
• Reduce training quality
• Suppress muscle protein synthesis

DEXA tracking helps athletes see the impact of scheduling stress and respond before losses compound.

Using DEXA Scans to Protect Muscle In Season

A DEXA Scan allows athletes to:

• Track lean muscle mass directly
• Identify early muscle loss
• Monitor asymmetries from overuse
• Adjust training and nutrition proactively

Without body composition data, muscle loss often goes unnoticed until performance declines.

How Often Should Athletes Track Muscle Mass?

For long competitive seasons:

• Body composition tracking every 6 to 8 weeks is ideal

This cadence allows timely adjustments without over monitoring.

The Bottom Line

Muscle loss during a long sports season is common but not inevitable. It happens when strength training, nutrition, and recovery are deprioritised in favour of volume and competition stress.

Maintaining muscle requires consistent strength stimulus, sufficient fuel, high protein intake, and adequate recovery. With DEXA Scan tracking at Kalos, athletes can protect muscle mass, sustain performance, and reduce injury risk across the entire season.
